September 1939. A Polish cavalry officer peers through binoculars at the horizon. What he sees makes no sense. Columns of dust rising from three directions at once. The rumble of engines, not dozens, but hundreds. Overhead, aircraft he cannot identify streak toward positions his commanders believed were secret.
Within 48 hours, his entire division will cease to exist as a fighting force. not destroyed in some titanic battle, but simply bypassed, encircled, cut off from supply, from communication, from [clears throat] hope. Across Poland, this scene repeats itself with horrifying consistency. Armies that mobilize to fight vanish before they can form proper lines.
Headquarters issue orders to units that no longer exist. Airfields burn before pilots can reach their planes. In Paris, in London, in capitals across Europe, leaders stare at dispatches they cannot believe. Poland, a nation of 35 million people with an army of nearly a million men, is collapsing, not in months, not in weeks, in days.
How is this possible? How does a country simply disappear from the map in the time it takes to read about it in newspapers? This is the question that haunted the world in September 1939. And it is the question that should haunt us still because the answer reveals something profound about how wars are won and lost about the gap between preparing for the last war and understanding the next one.
And about what happens when one side moves faster than the other can think. The world had seen wars before. The world had seen conquests before. But no one had ever seen anything like this. An entire nation with a proud military tradition stretching back centuries with fortifications and armies and aircraft gone in barely a month.
The implications were staggering. If Poland could fall this quickly, what about Belgium? What about the Netherlands? What about France itself? The nation that had bled Germany white for 4 years in the previous war. Suddenly, the comfortable assumptions of European security seemed like illusions. Suddenly, the future looked terrifying.
The easy answer, the one that dominated headlines then and persists in popular imagination now, is that Germany possessed some revolutionary secret. A wonder weapon, a new way of war so advanced that traditional armies simply could not compete. The newspapers called it blitzkrieg, lightning war. The term suggested something almost magical, a military sorcery that transformed the plotting, muddy, yearslong slaughter of the First World War into something swift, decisive, and unstoppable.
But this explanation, satisfying as it might be, is wrong. Or rather, it is so incomplete as to be misleading. Because what Germany actually possessed in 1939 was not magic. It was not even in many measurable ways superiority. What Germany possessed was a different understanding of time, of tempo, of what happens when you force your enemy to make decisions faster than their system allows.
And that difference, invisible on paper, impossible to quantify in tank counts or artillery pieces, would prove to be worth more than all the steel in Europe. To understand why Hitler’s early campaign succeeded so spectacularly, we need to strip away the mythology and examine what Germany actually had. And perhaps more importantly, what it did not have.
Because the myth of German military perfection is just that, a myth. The Vermacht that invaded Poland was not a fully modernized mechanized juggernaut. It was an army in transition, an army that had rearmed at breakneck speed, cutting corners everywhere, gambling that war would come before its weaknesses became apparent. The reality was stark and it would have surprised the terrified observers in London and Paris.
Most German infantry divisions in 1939 moved the same way infantry had moved in 1918 on foot with horses pulling their artillery and supply wagons. The German army of 1939 relied on approximately 750,000 horses for transport and logistics. This was not a force from the future. In many ways, it was still a force from the past, dressed in modern uniforms.
The famous Panza divisions, those spearheads of armored warfare that would terrify Europe, numbered just six at the start of the Polish campaign. Six out of more than 50 divisions committed to the attack. The overwhelming majority of German forces moved at the pace of a walking man. Roughly 3 mph on a good road, less across country.
German tanks themselves were often inferior to their opponents on paper. The most numerous German tank in Poland was the Panza 1, a training vehicle never intended for combat, armed with two machine guns and protected by armor so thin it could be penetrated by anti-tank rifles and even heavy machine guns at close range.
The Panza 2, only slightly better, mounted a 20 mm cannon, inadequate against anything but light targets and thin skinned vehicles. These two models made up the majority of German armor in 1939. The more capable Panza 3 and Panza 4,which would later become the backbone of German armored forces, existed in only small numbers.
French tanks, British tanks, even Polish tanks in some cases were more heavily armored and more powerfully armed than what Germany fielded. The French Char1, for example, mounted a 75 mm gun and carried armor that German tank guns struggled to penetrate. On paper, it should have been dominant. So, if Germany was not superior in raw military power, if its tanks were often weaker, if most of its army still marched on foot, if its industrial base was smaller than those of its combined enemies, what was different? what allowed this incomplete,
still developing military machine to achieve results that seemed impossible. The difference lay in how Germany prepared for war and how it thought about war. Beginning in the 1920s, even while officially disarmed under the Treaty of Versailles and limited to a token force of just 100,000 men, German military thinkers had studied the lessons of the First World War with an intensity bordering on obsession.
The Reichkes, as the interwar German army was called, became essentially a school for officers. With so few soldiers allowed, quality became paramount. Every enlisted man was trained to eventually become a non-commissioned officer. Every officer was trained to think at levels above his current rank, and the intellectual work that occurred in this period would shape everything that followed.
German strategists asked questions their counterparts in France and Britain largely avoided. They did not simply celebrate their victory or mourn their defeat. Germany had lost the war after all. They dissected it. Why did the Western Front become a stalemate? What would it take to restore mobility to warfare? How could an attacking force break through entrenched defenses before the defender could bring up reserves? How had infiltration tactics developed late in the war achieved local successes? Could these be scaled up? And crucially, how could
modern technology, particularly the tank and the airplane, change the answers to all of these questions? The German military that emerged from this intellectual firmament, was not necessarily better equipped than its rivals. But it was better prepared to use what it had. Officers were trained to think in terms of tempo, the pace of operations, rather than simply position.
They understood that in modern warfare, time was a weapon as surely as artillery. They were taught to seek decision points where concentrated force could shatter enemy cohesion rather than grinding through defenses inch by inch. They learned to think not just tactically about winning the firefight in front of them, but operationally about how tactical actions could combine to achieve campaign objectives.
Most importantly, they were given authority to act on their own initiative when opportunities appeared rather than waiting for orders from distant headquarters. This command culture, often called AFRA’s tactic or mission type tactics, was perhaps Germany’s greatest military advantage. The concept was deceptively simple.
Commanders would receive objectives rather than detailed instructions. They were told what to achieve, not precisely how to achieve it. A division commander might be told to seize a particular crossroads by a certain time. How he organized his forces, which routes he chose, how he responded to unexpected enemy resistance or opportunities.
These decisions were his to make. This required exceptional training and mutual trust between ranks. It required officers who could think independently and enlisted men who could adapt when plans fell apart. But it also meant that German forces could react to changing situations with a speed that centralized command systems simply could not match.
In an era when radio communication was still unreliable and easily disrupted, this was an enormous advantage. A French battalion commander whose radio failed might halt and wait for new instructions paralyzed without guidance from above. A German battalion commander in the same situation would assess the situation, consider the mission, consider what his superior would want him to do, and act.
While the French commander waited, the German commander moved. Multiply this across hundreds of units, dozens of engagements, and the cumulative effect was devastating. The German army didn’t just move faster physically, it decided faster, adapted faster, exploited opportunities faster. It operated inside the enemy’s decision cycle, acting before the enemy could react, forcing the enemy into a perpetual state of responding to yesterday’s situation while today’s situation had already changed. But here we must pause because
if you have been listening closely, a question should be forming in your mind. If German advantages were primarily doctrinal and organizational, why didn’t other armies adopt similar approaches? The French had tanks, good tanks, arguably better tanks than Germany inmany cases. The British had radios and a proud military tradition.

Poland had brave soldiers and competent officers who had successfully defended their nation against Soviet invasion in 1920. Why didn’t everyone simply copy what worked? Why didn’t French generals study the same lessons from the First World War and reach the same conclusions? The answer reveals one of the most important truths about military innovation and one of the most important reasons for Germany’s early success.
Military institutions are conservative by nature. They prepare for the wars they remember. They are shaped by their experiences, their victories, their traumas. And the war that Britain and France remembered was the First World War. A conflict that had taught them with millions of casualties that defense was stronger than offense, that artillery was king, that attacking fortified positions meant slaughter, that wars were won through attrition, through blockade, through the slow strangulation of enemy resources.
Everything about French strategic planning in the 1930s reflected these assumptions. The Magino line, that massive fortress system along the German border with its underground railways and airond conditioned barracks and retractable artillery turrets, was not a failure of imagination. It was the physical embodiment of lessons learned at Verdon and the SO.
The idea was simple and in its own way brilliant. Force Germany into the same attritional war it had lost before. Make the Germans bleed themselves white against concrete and steel while French industry outproduced them and the British naval blockade starved them. Don’t attack. Don’t waste lives in futile offensives. Let the enemy come to you.
Let the enemy die. It was a perfectly rational strategy for fighting the last war. The French had won that war after all. Why change what worked? But Germany had no intention of fighting the last war. Germany couldn’t afford to fight the last war. German strategists understood perfectly well that in a long attritional conflict, Germany would lose.
Germany’s industrial base was smaller. Germany lacked access to global resources. Germany could be blockaded and starved just as it had been in 1918. Every assumption that made French strategy rational made German strategy desperate. Germany had to win quickly or not at all. And that desperation drove innovation.
This is where the concept popularly known as blitzkrieg enters our story. Though we should immediately note that German military planners rarely used this term themselves. It was largely a creation of journalists, a catchy label applied after the fact to describe operations that succeeded beyond anyone’s expectations. German doctrine didn’t call itself blitzkrieg.
It simply called itself modern warfare. What the Germans actually practiced was something more subtle and more profound than a single tactical innovation. It was an approach to warfare that integrated multiple elements into a coherent whole. Elements that individually were not revolutionary, but together created something far greater than the sum of their parts.
Start with the fundamental insight that had emerged from studying the First World War. Breakthrough means nothing if it cannot be exploited. In the first world war, attackers occasionally punched holes in enemy lines. The British at Cambri in 1917. The Germans in their spring offensives of 1918. Both achieved dramatic initial breakthroughs.
But infantry exhausted from the assault could not advance fast enough to prevent defenders from sealing the breach. Reserves moving by rail and road always arrived in time to create a new line. The breakthrough became a bulge. The bulge became a salient. The salient became a trap. Attackers who pushed too far forward found themselves vulnerable to counterattack on three sides.
The solution was obvious in retrospect, but revolutionary in practice. Mobile forces, tanks, motorized infantry, motorcycle troops had to exploit breakthroughs before defenders could react. Speed was not just an advantage. Speed was the weapon itself. If you could advance 50 mi in a day, you could be behind enemy lines before the enemy knew you had broken through, you could cut communications, sever supply lines, capture headquarters, spread panic far beyond the immediate battlefield.
The enemy wouldn’t just be fighting you. They would be fighting their own confusion, their own fear, their own disintegrating command structure. But speed alone was not enough. Mobile forces advancing deep into enemy territory would quickly become isolated, their flanks exposed, their supply lines stretched thin.
They would outrun their artillery support, outrun their infantry, outrun their fuel and ammunition. A bold thrust could become a disaster if the enemy could concentrate against it. This is where the second element became critical. Coordination. German doctrine emphasized combined arms, the integration of tanks, infantry, artillery, and aircraft into asingle synchronized effort.
Tanks would break through. Infantry would follow to hold the ground and protect the flanks. Artillery would suppress enemy positions. And aircraft, this was crucial, would provide both reconnaissance and fire support far beyond the range of groundbased artillery. The technology that made this synchronization possible was the radio.
German tanks carried radios. German headquarters could communicate with forward units in real time. German aircraft could respond to calls for support within minutes rather than hours. Commanders could adjust plans as situations developed, shifting forces to exploit success or shore up failure. This seems unremarkable today in an age of instant global communication.
But in 1939, it was genuinely revolutionary. French tanks, by contrast, often lacked radios entirely. Coordination between French armored units depended on hand signals, flags, colored penants, or messengers physically traveling between vehicles. These methods were adequate for the pace of 1918 and hopeless against an enemy operating at the speed of 1939.
A French tank commander who spotted an opportunity would have to stop, dismount, find a messenger, send word back to headquarters, wait for a response, and only then act. By that time, the opportunity would be gone. The Germans would already be somewhere else. The third element was perhaps the most important and the least visible, operational art.
German planners thought in terms of entire campaigns, not just individual battles. They sought to create situations where tactical victories could cascade into strategic collapse. The preferred method was encirclement, what the Germans called kessel, literally cauldron battle. The goal was not to push the enemy back through bloody frontal assault.
The goal was to cut off enemy forces from supply and reinforcement, to surround them, to force them to surrender or be destroyed peacemeal. An encircled army might still be intact, might still have ammunition and food for days, might still be full of soldiers willing to fight, but it was already defeated.
It could not receive reinforcements. It could not coordinate with other forces. It could not retreat to fight another day. It could only surrender or die. This was not a new idea. Hannibal had encircled the Romans at Cana more than 2,000 years earlier, destroying a force twice the size of his own. German military theorists had studied CA endlessly, dreaming of replicating it with modern technology.
What they developed was a doctrine that systematized encirclement thinking, trained officers at every level to identify opportunities for it, and provided them with the mobile forces to execute it at unprecedented speed and scale against an enemy. expecting a linear first world war style advance, an enemy planning to trade space for time, to fall back to prepared positions, to fight a methodical defensive campaign.
This approach was devastating. Now we come to Poland, the first test of these ideas against a real opponent in a real war. And here we must be careful to understand what actually happened because the Polish campaign has been distorted by myth from both directions. The German myth portrayed Poland’s defeat as inevitable, the crushing of a backward nation by an invincible war machine.
According to this version, Polish cavalry charged German tanks with lances, a story that persists to this day, despite being largely propaganda. The Polish myth sometimes went to the opposite extreme, portraying the campaign as a hopeless struggle against overwhelming odds, minimizing German skill and maximizing German numbers, suggesting that nothing Poland could have done would have changed the outcome.
Neither version captures the reality. Poland in 1939 was not a military pushover. It had an army of roughly 1 million men when fully mobilized, including cavalry formations that were genuinely elite. Though they fought dismounted as mobile infantry, not charging tanks with sabers. Poland had well-trained infantry and competent artillery.
It had a small but capable air force. Polish soldiers would fight with extraordinary courage. In some cases, holding positions for days against odds that should have made resistance impossible. Polish cryptographers had already broken early versions of the German Enigma code, sharing their work with the British and French, an achievement that would later prove crucial to Allied victory.
Poland’s problem was not lack of courage or capability. Poland’s problem was time and geography and enemies on all sides. Consider the strategic situation. Poland’s western border curved around Germany like a crescent with German territory to the west and to the north in East Prussia. This meant that any German attack could come from multiple directions simultaneously.
Polish forces attempting to defend the border would be spread thin across hundreds of miles, vulnerable to being cut apart by converging thrusts. The alternative, concentrating forcesfurther east to avoid encirclement, meant abandoning Poland’s industrial heartland without a fight, seeding the coal mines and factories and major cities that would be needed to sustain a long war.
It also meant abandoning millions of Polish citizens to German occupation. Neither option was acceptable. Polish planners chose a compromise. defend forward, delay the German advance, and wait for France and Britain to attack Germany from the west, forcing Hitler to divert forces. If Poland could hold for three or four months, the thinking went, German attention would have to shift westward.
It was a reasonable plan. It assumed allies would act. It assumed the war would last months, not weeks. Both assumptions proved tragically wrong. Germany attacked on September 1st, 1939 with a force of 54 divisions, including those six precious Panza divisions. The assault came from three directions, from the west, from the southwest through Slovakia, which had become a German client state, and from East Prussia in the north.

Polish border defenses designed to delay rather than halt the German advance, were overwhelmed not by sheer numbers, but by speed and coordination. Luftvafa aircraft struck airfields, rail junctions, communication centers, and mobilization points in the opening hours, disrupting Polish mobilization before it could complete. Many Polish reserveists never reached their units.
Orders never reached their destinations. Headquarters lost contact with subordinate formations. The chaos was not accidental. It was the point. German ground forces did not advance methodically along the entire front the way armies had moved in the First World War. Instead, armored spearheads punched through at key points and race deep into Polish territory, bypassing strong points, severing communication lines, creating chaos in the rear.
Infantry followed to reduce bypassed positions and hold captured ground, but the tanks never stopped. Polish units prepared to defend against a frontal assault found themselves fighting not the enemy in front of them but the enemy behind them. Cutting their supply lines, threatening their headquarters, encircling them before they could retreat.
And here is where the tempo advantage became decisive. Polish commanders, brave and competent as individuals, could not make decisions fast enough to respond. Their command structure required detailed orders from above. Their communications were being systematically destroyed. By the time they identified a German thrust and issued orders to counter it, the Germans had already moved.
The panzas might be 20 or 50 mi beyond where Polish intelligence placed them. Reserves marching to reinforce one sector arrived to find it already bypassed, the battle somewhere else entirely. Orders issued in the morning were obsolete by noon. The entire Polish command structure was operating on information that was hours or days out of date, while German commanders were operating in something approaching real time.
The psychological effect was devastating. Units that had not been defeated in combat. Units still at full strength, still willing to fight, found themselves encircled, cut off from supply, ordered to surrender to prevent senseless slaughter. This was the German way of war in action. Not destroying the enemy army through bloody frontal assault, but dislocating it, shattering its cohesion, forcing it to collapse under the weight of its own confusion.
Polish soldiers didn’t lose because they were cowards or incompetence. They lost because they were operating in a system that could not adapt fast enough to survive. Yet, even as German forces sliced through Poland with terrifying efficiency, there were moments when the outcome remained uncertain. >> [clears throat] >> Polish resistance in some sectors was fiercer than expected.
The battle of Bizura launched in the second week of the campaign saw Polish forces counterattack with surprising force, temporarily disrupting German timets and causing real concern at German headquarters. German logistics stretched by the speed of the advance showed signs of strain. Tanks broke down. Fuel ran short.
Casualties while light by First World War standards were not trivial. German forces suffered roughly 16,000 killed in the campaign with many more wounded. The Vermacht was learning that mobile warfare extracted its own costs. And then on September 17th, any hope of prolonged Polish resistance ended. The Soviet Union invaded from the east.
Under the terms of the secret Molotov ribbon pact signed just weeks earlier, Stalin and Hitler had agreed to partition Poland between them. Whatever else divided Nazi Germany and communist Russia, and much did, they shared a desire to destroy the Polish state that stood between them. Polish forces, already reeling from the German assault, now faced a two-front war they could not possibly win.
Roughly 800,000 Soviet troops poured across the eastern border, meeting little organized resistance. ThePolish government fled to Romania, then to France, eventually to London. Warsaw held out heroically until September 27th, enduring aerial bombardment and artillery fire that killed tens of thousands of civilians and reduced much of the city to rubble.
But by early October, organized Polish resistance had ceased. A nation had been erased from the map in 35 days. It would not reappear for nearly 50 years, and then only after the Soviet Union itself collapsed. In London and Paris, the shock was profound. Intelligence estimates had assumed Poland would resist for at least several months, buying time for the Western powers to mobilize their vastly greater resources.
Instead, Poland had fallen before French forces could even complete their deployment to the front. The implications were clear. Whatever had happened in Poland could happen elsewhere. Germany’s full might could now turn westward. But here, something strange happened. Something that would prove almost as consequential as the Polish campaign itself.
The Western Allies did almost nothing. Britain and France had declared war on Germany on September 3rd, honoring their treaty obligations to Poland. French forces had made a tentative advance into the Sar region of Germany in the war’s opening days, occupying a few German villages against minimal resistance.
For a brief moment, there was an opportunity. Germany had committed nearly all its combat power to Poland, leaving the western border lightly defended. A determined French offensive might have achieved significant results. But by midepptember, with Poland clearly doomed, the French halted and withdrew. And then nothing.
Through the autumn of 1939 and into the winter of 1940, the Western Front remained quiet. Soldiers on both sides stared at each other across fortifications. Artillery fired sporadically, more to maintain readiness than to achieve any objective. patrols probed enemy lines without conviction. Troops trained, dug trenches, played cards, wrote letters home, and waited for something to happen.
Journalists, bewildered by this war without fighting, called it the phony war. The Germans called it sitskrieg, the sitting war. The French called it droll dear, the funny war, though there was nothing funny about it. Millions of men under arms. Two of the world’s largest empires formerly at war with Europe’s most aggressive power. And yet peace, an eerie, tense, waiting peace that everyone knew could not last, but that no one seemed willing to break.
Why did the Western Allies wait? Why, with Germany still consolidating its conquest of Poland, still off balance, still vulnerable in the West, did France and Britain fail to attack? The reasons were multiple and mutually reinforcing. First, there was the memory of the First World War, a trauma that hung over French strategic thinking like a shroud.
France had lost nearly 1.4 million dead in that conflict. An entire generation bled white in futile offensives that gained nothing but corpses. The French military leadership of 1939 had served as junior officers in those battles. They had led men over the top at Verdon and the Som.
They had seen what happened when armies attacked prepared defenses. They were not eager to repeat the experience. Every instinct, every lesson, every scar told them the same thing. Let the enemy attack. The Majino line was not just a fortification. It was a philosophy made concrete. Let Germany attack. Let Germany bleed. France would wait, conserve its strength, and win through superior staying power, just as it had in 1918.
Second, the Western Allies genuinely believed time was on their side. British and French industrial capacity, combined with access to global resources through their colonial empires, would eventually outproduce Germany. The British naval blockade, which had slowly strangled Imperial Germany in the First World War, would do the same to Hitler’s Reich.
Germany was already rationing food. German industry depended on imported raw materials that the blockade was cutting off. Why rush into battle when patients would deliver victory at lower cost? Why spend French lives when time itself was killing Germany? Third, and this is often overlooked, the Western Allied militaries simply were not ready for offensive operations.
French mobilization was slow and methodical, designed for a long war rather than a short campaign. British forces in France numbered barely a dozen divisions by the end of 1939 compared to the 60 that had fought in 1918 and the hundreds that would eventually be needed. Launching a major offensive with these forces against German defenses that grew stronger every day seemed not bold but reckless.
Better to build up strength, train troops, accumulate reserves, and strike when the moment was right. Finally, there was the political dimension that complicated everything. Neither the French nor British governments were entirely certain their populations would support an aggressive war.
Poland had fallen tooquickly for public outrage to truly build. Hitler was making peace overures, offering to negotiate now that he had what he wanted in the East. Some in London and Paris hoped the war might simply end, that some face-saving compromise might be found. There were those who wondered whether the war was really necessary at all. Why sacrifice thousands of lives for a war that might not need to be fought? Why not wait and see if diplomacy might succeed where Poland’s army had failed? These questions would later seem obscene in light of what Hitler actually intended.
But in the autumn of 1939, before the full horror of Nazi rule became apparent to the world, they did not seem unreasonable. But while the allies waited and hoped and debated, Germany acted. Every day of the phony war was a gift to the Vermacht. Divisions that had fought in Poland were rested, refitted, and reinforced.
Tank losses were replaced, often with improved models. Lessons from the campaign were studied, analyzed, and incorporated into doctrine. Factories that had strained to equip the Polish campaign now accelerated production. New divisions were formed. The army that would face the West in 1940 was significantly more capable than the one that had invaded Poland.
Larger, better equipped, more experienced, more confident. Meanwhile, the opportunity costs for the Allies mounted invisibly but relentlessly. Time that could have been spent launching offensives while Germany was off balance was instead spent building more fortifications. Time that could have been spent developing new tactics was spent refighting the last war in planning documents.
Time that could have been spent integrating tank and air forces into coherent combined arms formations was spent treating tanks as infantry support weapons dispersed among divisions rather than concentrated for breakthrough. Every month of inaction allowed Germany to concentrate its forces westward to prepare the blow that would fall in spring.
And this brings us to the edge of disaster, to the moment when Germany’s early successes would compound into something that almost defied belief. Because what came next would make Poland look like a preliminary bout, a warm-up exercise for the main event. By the spring of 1940, German planners had developed something audacious.
A campaign designed not just to defeat France, but to knock it out of the war entirely, to achieve in weeks what Imperial Germany had failed to achieve in four long years. The plan that emerged after months of debate, revision, and argument at the highest levels violated every principle of cautious military strategy. It concentrated forces at their most vulnerable point rather than their strongest.
It sent tanks through terrain that experts declared impossible. It gambled everything on speed and shock, assuming the enemy would react exactly as expected. It was, by any reasonable measure, reckless to the point of madness, and it was about to work beyond the wildest dreams of those who conceived it. But before Germany turned west in full force, there would be another theater, another campaign that would demonstrate the same principles of speed, coordination, and operational daring that had crushed Poland.
To the north, neutral nations watched the phony war with growing unease. Norway, Sweden, Denmark. They hoped perhaps that the conflict would pass them by. They clung to neutrality as a talisman, as if declarations of non-involvement could protect them from the storm that was reshaping Europe. They were about to learn otherwise.
Scandinavia, with its iron ore that German industry desperately needed, with its coastlines that could shelter German naval forces or British ones was next. And what happened there would shock the world almost as much as Poland had. It would prove that Poland was not a fluke, not a lucky accident.
The lightning was about to strike again. And after Scandinavia, the main blow would fall. France, the enemy that Germany had failed to defeat in four years of the bloodiest fighting in human history. France with its mighty army and its impregnable fortresses. France that had bled Germany white at Verdon. France was next.
And France had no idea what was coming. May 1940. A French general stares at a map in disbelief. The reports cannot be accurate. German tanks, hundreds of them, have appeared in a sector where tanks should not exist. The Arden’s forest, that impenetrable tangle of hills and ravines and narrow winding roads, was supposed to be impossible for armor.
Every French military expert had said so. Every war game had confirmed it. The entire defensive strategy of France rested on the certainty that no army could push a major armored force through those woods quickly enough to matter. And yet here they are somehow impossibly the Germans have done what doctrine declared impossible.
And they are not just through the forest. They are across the Muse River. They are behind the French lines. They are racing for the EnglishChannel at a speed that defies every principle of military logistics. The reports say German armor is advancing 40, 50, even 60 mi in a single day. Impossible. Tanks cannot sustain that pace. Fuel runs out. Engines break down.
It must be an error. But the reports keep coming and they keep getting worse. In Paris, the government begins burning documents. In London, Churchill receives dispatches he refuses to believe. In the fields of Northern France, the most powerful army in Western Europe is dying. Not from lack of courage, not from lack of equipment, but from something harder to name.
It is dying because it cannot think fast enough to survive. This is the story of how Adolf Hitler achieved the most stunning military victories in modern history and why those victories contained the seeds of his eventual destruction. You saw the Vermach’s real advantages. Not superior tanks or overwhelming numbers, but tempo.
The ability to make decisions and execute actions faster than the enemy could respond. You saw how combined arms coordination and radio communication allowed German forces to concentrate overwhelming power at decisive points while their opponents struggled to understand what was happening. And you saw how the Western Allies sat paralyzed through 8 months of the phony war, watching their assumptions crumble, but unable to adapt.
Now we continue that story through 1940 and into 1941. Campaigns that would see Germany conquer most of Western Europe in weeks, push Britain to the brink of defeat, and sweep through the Balkans with terrifying efficiency. But we will also see the first cracks in the edifice, the first signs that speed alone cannot win every battle.
and the gathering storm of a decision so catastrophic that it would doom everything Hitler had built. Before Germany could turn its full attention westward, there was unfinished business to the north. Scandinavia held resources that both sides desperately needed. Swedish iron ore, among the highest quality in the world, flowed to German factories through Norwegian ports.
In winter, when the Baltic froze, the ice-free harbor at Narvik became Germany’s lifeline. Without that ore, German steel production would collapse. Tanks would not be built. Shells would not be manufactured. The war would be lost in the factories before it was decided on battlefields. Britain understood this vulnerability.
Plans developed to mine Norwegian waters to cut the ore route, perhaps to occupy Norway entirely. Churchill pressed for action, but British planning moved slowly through committees and debates and political considerations. German planning moved faster. On April 9th, 1940, Germany struck Denmark and Norway simultaneously.
Denmark fell in 6 hours, the fastest conquest in modern military history. The Danish king surrendered to avoid pointless bloodshed, and by noon, German forces occupied Copenhagen. Norway was far more difficult. The distances were vast, the terrain mountainous, the coastline endless. For the first time, Germany would project power across water, challenging British naval supremacy.
German naval forces vastly inferior to the Royal Navy carried invasion troops to multiple Norwegian ports simultaneously. Oslo, Bergen, Tronheim, Narvik. It was a gamble that defied conventional wisdom and German losses were severe. The heavy cruiser Blucer was sunk by Norwegian coastal guns on the first day. At Narvik, the Royal Navy destroyed 10 German destroyers, half the German destroyer force.
Other cruisers were lost or damaged. The German surface navy would never fully recover. But the gamble worked. German troops seized objectives before effective opposition materialized. Paratroopers captured crucial airfields, allowing Luftvafa aircraft to contest British air superiority. By the time Allied expeditionary forces arrived, the Germans were already entrenched, already operating inside the Allied decision cycle.
The Allied forces that landed found themselves fighting uphill in every sense. German air power punished their supply lines. The British actually recaptured Narvik in late May, but by then catastrophe had struck in France. Every available soldier was needed on the western front. Norway was evacuated. By early June, the country fell under German occupation.
What truly matters about the Norwegian campaign beyond immediate military outcomes is three-fold. First, it secured Germany’s strategic northern flank for the remainder of the war and guaranteed uninterrupted access to Swedish iron ore, approximately 10 million tons annually, without which German war production would have been impossible to sustain.
That ore would flow to German factories throughout the war years, becoming the steel for tanks and aircraft, the shells for artillery, the hulls for yubot. The strategic value was incalculable. Second, the campaign demonstrated that Germany was willing to accept painful costs, genuinely painful, crippling costs in some categories when thestrategic gain justified them.
The naval losses were severe enough to affect German surface fleet operations for the remainder of the war. But the strategic gain was worth the price. This risk tolerance combined with meticulous planning and ruthless speed of execution could achieve results that conventional military wisdom declared impossible. Third, and perhaps most critically, for understanding the pattern of German success, the Norwegian campaign happened while Britain and France were still debating what to do.
Germany acted while Britain discussed. The tempo advantage was operating again, now across air, sea, and land. The pattern was unmistakable, but the true demonstration was days away. May 10th, 1940. The blow Europe had awaited for 8 months finally fell. German forces attacked the Netherlands, Belgium, Luxembourg, and France with over 3 million men, thousands of aircraft, and 10 Panza divisions.
On paper, the forces were roughly equal. The Allies had more tanks, over 3,000 French alone. Many were superior to German models. The French Char B1 mounted a 75 mm gun with armor. German weapons could not penetrate frontally. French artillery was excellent. The British expeditionary force was professional and well equipped.
Behind them stood the Majino line and the resources of two global empires. Against this, Germany had speed, coordination, and a plan so reckless that many of Hitler’s own generals opposed it. The original plan fal gelb was conventional a strong thrust through Belgium essentially a modern schlie plan allied intelligence expected this because military logic dictated it Belgian terrain was ideal for armor flat well-roaded the allies positioned their best forces to meet this expected attack planning to advance into Belgium when Germany struck but the
plan actually executed was different a scheme pushed by General Eric von on Mannstein supported by tank commanders like Gderion and adopted by Hitler over the objections of the army high command. Instead of Belgium, the main blow would fall through the Arden forest. The Ardens was hilly, forested, crossed by narrow roads.
French doctrine stated moving major armor through such terrain would take 2 weeks, enough time to detect and respond. Therefore, the sector was held by second rate reserveist divisions. Seven Panza divisions, 1500 tanks, would thread through those forest roads, emerge at the Muse River at Sudan, smash through weak French positions, and race for the channel.
If it worked, Allied armies in Belgium would be encircled and destroyed. If it failed, if columns got stuck, if French aircraft bombed the traffic jams, if the river crossings were defeated, Germany would have trapped its best forces with no escape. The entire war hung on a single throw. Why take such risk? Because German planners understood that the Arden was not truly impossible.
Difficult, yes, but traversible with speed and determination. And French doctrine guaranteed light observation. Because French doctrine said no rational commander would attempt it, the gamble would work precisely because it violated what the enemy believed possible. Germans attacked on May 10th. By May 12th, armor was emerging from the forest.
Terrain covered in 3 days that French doctrine said would take 2 weeks. French reconnaissance spotted the massive traffic jams. Reports went up the chain, but French high command could not process information contradicting their assumptions. It must be a faint. The real attack must be in Belgium. Then came May 13th, the day the war was decided.
Under relentless Luftvafa bombardment, waves of stookers screaming down with their wailing sirens. German infantry crossed the muse in rubber boats. The air attack was psychological as much as physical. French soldiers who had endured First World War shelling had never experienced this sustained terrifying assault from the air.
Many broke. Engineers began bridging the river under fire. By evening, German troops held bridge heads. By morning, tanks were crossing. By May 15th, armor was breaking out into open country. The French high command confronted the impossible. The enemy was where the enemy could not be. What happened next illustrates why Germany won so completely.
The French had reserves, tanks, artillery, millions of men. What they did not have was time. German armor, having broken through, did not pause to consolidate. They ran. Gderrion drove his panzas westward so fast that Hitler himself tried to halt the advance, terrified of exposed flanks. Gudderion essentially ignored the orders.
Every mile advanced was a mile France could not recover. Every hour gained put the French decision cycle further behind. The French command system collapsed under the strain. Orders were issued to positions already abandoned. Reserves marched to reinforce sectors already bypassed. Communications broke down. The fog of war descended like blindness, and through it, German armor moved with certainty toward thecoast.
On May 20th, 10 days after the offensive began, German tanks reached the sea at Abil. The trap had closed. Allied armies in Belgium were completely cut off from France. Nearly a million men, including the entire British Expeditionary Force, were trapped in a rapidly shrinking pocket with their backs to the sea and no prospect of relief.
What followed was one of the most remarkable episodes of the war. Remarkable not for German success, but for Allied deliverance. The evacuation from Dunkirk, Operation Dynamo, was made possible by several factors. Hitler’s controversial decision to halt the Panzer advance on May 24th, giving the Allies crucial days to establish a defensive perimeter, the desperate sacrifice of French rear guard units who held the perimeter while British and French troops embarked.
The extraordinary courage of the Royal Navy and the famous little ships, civilian vessels of every description that crossed the channel to rescue soldiers from the beaches, and weather that at times grounded the Luftvafa. Over 9 days, 338,000 soldiers were evacuated to Britain, a number far exceeding anything planners had thought possible.
It was a deliverance that saved an army. But it was not a victory. The evacuated troops left behind every tank, every artillery piece, every vehicle, every piece of heavy equipment the British army possessed. France had nothing left to save it. The second offensive phase launched June 5th, shattered remaining resistance. Paris fell June 14th.
France requested an armistice June 17th. On June 22nd, French representatives signed surrender terms in the same railway car where Germany had accepted the armistice in 1918. 6 weeks. France, the nation that had bled Germany white for 4 years, conquered in 6 weeks. German dead approximately 27,000. French dead over 90,000.
With 200,000 wounded and nearly 2 million prisoners, the disparity was not courage. It was tempo. The fall of France left Britain alone. The last major power in Western Europe, still resisting German domination. Across the English Channel, German forces assembled, flushed with victory, seemingly unstoppable.
20 mi of water separated the conquered continent from the unconquered island. Those 20 mi would prove impossible, but no one could be certain of that. In the summer of 1940, Churchill rallied his nation with unforgettable defiance. We shall fight on the beaches. We shall fight on the landing grounds.
We shall fight in the fields and in the streets. We shall never surrender. The words stirred British resolve, but rhetoric alone could not stop Panza divisions. The army that had evacuated from Dunkirk had left behind virtually all its heavy equipment, tanks, artillery, transport vehicles, ammunition.
If German forces crossed the channel and established themselves on British soil, there was genuine doubt whether the British army could mount effective resistance. What would stop Germany, if anything could, was the English Channel and the aircraft of the Royal Air Force that guarded the skies above it.
Hitler understood that invasion of Britain required air superiority. German forces could not cross the channel if British fighters and bombers sank the invasion barges at will. The landing craft, the transport ships, the support vessels, all would be sitting ducks if the RAF controlled the skies above the crossing. So began the Battle of Britain.
The first major campaign in history fought primarily in the air and the first significant German defeat of the entire war. Why did the winning streak stop here? Why could Germany conquer France in 6 weeks but not cross 20 m of water? The answer reveals the fundamental limits of the German approach that had worked so brilliantly on land.
Germany’s advantages, tempo, combined arms coordination, operational encirclement, all assumed continuous ground where mobile forces could maneuver. The English Channel negated every one of these advantages. Tanks could not swim across it. There was no possibility of a flanking movement, no way to encircle the enemy.
Either you crossed the water or you did not. There was no middle ground, no partial solution, no operational art that could transform a difficult situation into a winning one. The battle became a contest of attrition. Exactly the kind of fight Germany had organized its entire military to avoid. Exactly the kind of fight that favored the side with greater resources and staying power.
And in that contest of attrition, Britain possessed advantages Germany had not faced in any previous campaign. The heart of British air defense was radar, a technology Britain had developed with urgency through the 1930s and deployed in a chain of stations along the entire southern and eastern coastline. These radar stations could detect German aircraft as they assembled over France, track their approach across the channel, and provide early warning that allowed RAF fighter command to respond with maximum efficiency. This singletechnological advantage transformed the
entire nature of the air battle. British fighters did not have to patrol endlessly, burning precious fuel and wearing out engines and exhausting pilots. They could wait on the ground, conserving their strength, and scramble only when raiders approached. Ground controllers could vector them toward incoming German formations, allowing them to climb to advantageous altitude and position themselves for effective interception.
German fighters faced exactly the opposite mathematics. Messmid 109’s, the Luftvafer’s best fighters, had limited fuel capacity. crossing the channel and fighting over England, they could spend perhaps 15 or 20 minutes in actual combat before fuel ran critically low. That was barely enough time to engage and certainly not enough to sweep British fighters from the sky in the sustained way that air superiority required.
Worse still, British pilots who were shot down over their own country could parachute to safety. If uninjured, they could be flying again within days, sometimes within hours. German pilots who bailed out over England became prisoners of war, permanently removed from the battle. Every German pilot lost was gone forever.
Many British pilots lost were recycled back into the fight. British aircraft production, dispersed and protected, replaced losses faster than the Luftwaffer could inflict them. Lord Beaverbrook, placed in charge of aircraft production with emergency powers, drove British factories to extraordinary output. Fresh pilots trained in Canada and elsewhere in the Commonwealth, where they were safe from German bombs, arrived to replace the fallen.
Week by week, the mathematics of the battle turned inexraably against Germany. The Luftvafa was bleeding, losing experienced pilots and irreplaceable aircraft, and it was not achieving its fundamental objective of destroying fighter command. In September 1940, after particularly heavy losses in a series of daylight raids on London, Germany effectively conceded defeat in the air war.
The invasion barges that had been assembled in French and Belgian ports were quietly dispersed. Operation Sea Lion, the planned invasion of Britain, was postponed indefinitely, which meant permanently. The crisis passed. Britain survived. The war would continue. Germany had conquered Poland, Denmark, Norway, the Netherlands, Belgium, Luxembourg, and France.
It had won every campaign on the continent of Europe, and yet it had not won the war. The implications of this failure, though not fully apparent at the time, would prove decisive. As long as Britain held out, Germany faced an undefeated enemy to its west. An enemy with access to the resources of a global empire.
An enemy increasingly supported by the industrial might of the United States. The ring had not closed. The victory remained incomplete. The year 1941 opened with Germany dominant across Western and Central Europe, but the strategic situation was more fragile than surface appearances suggested. Britain remained defiant.
its factories producing weapons, its air force rebuilding, its navy still ruling the seas. American support for Britain was growing through lend lease and other programs. Time was not obviously on Germany’s side, and complications had emerged in the south. Italy, Germany’s principal ally, had invaded Greece in October 1940 with expectations of easy conquest.
Instead, the Greeks had routed the Italian forces with embarrassing completeness, driving them back into Albania and inflicting humiliating defeats. By early 1941, British forces were arriving in Greece to support the Greek defense. A British presence in the Balkans threatened Germany’s southern flank and more critically endangered the Romanian oil fields upon which German industry and the German military depended absolutely.
Hitler could not tolerate this threat. Germany would have to intervene to clean up the mess Mussolini had created. But events moved faster than German planning. Yugoslavia, which had initially agreed to join the Axis powers, underwent a military coup on March 27th that brought an anti-German government to power.
Hitler, furious at this betrayal, ordered immediate invasion. Yugoslavia would be destroyed as a state, he declared. On April 6th, 1941, German forces attacked Yugoslavia and Greece simultaneously. The Balkan campaign of April 1941 demonstrated German operational superiority one final time, but with characteristics that should have served as warnings.
The pattern was familiar. Coordinated air and ground assault, rapid armored thrusts, finding gaps in enemy lines, encirclement of defending forces, collapse of command and control under the pressure of speed and shock. Yugoslavia, torn by internal tensions between Serbs, Croats, Sloines, and other ethnic groups who trusted each other almost as little as they trusted the invader, shattered in 11 days.
Belgrade was devastated by Luftvafa bombing on the campaign’s first day andGerman armored columns sliced through the country before effective resistance could coalesce. The Yugoslav army surrendered on April 17th. Greece held longer, 3 weeks in all, despite mountainous terrain that theoretically should have strongly favored the defense.
The Greek army, already exhausted from months of fighting against the Italians in Albania, now faced a far more formidable opponent. Greek and British forces fought with genuine determination, and the terrain offered natural defensive positions that seemed almost impregnable. Mountain passes could be held by small forces against large ones.
The road network was limited, canalizing any advance along predictable routes. All the advantages seemed to favor the defenders, but the same German operational advantages that had crushed Poland and France operated once again. Speed dislocated defenders before they could establish stable positions.
When Greek forces prepared to hold one pass, German units found alternative routes or simply advanced so rapidly elsewhere that the defended position became irrelevant. Luftwafa air superiority punished any attempt to move or concentrate forces during daylight hours. Greek and British artillery, infantry, supplies. Anything that moved on the roads became targets.
Coordination between German ground and air forces proved far superior to the improvised cooperation between Greek and British units who had never trained together and who communicated through different systems in different languages. By late April, British forces were evacuating Greece in scenes grimly reminiscent of Dunkirk.
Another hurried abandonment of equipment and heavy weapons. Another humiliating retreat that preserved men at the cost of material. The swastika flew over the Acropolis. By the end of April, Germany controlled the entire Balkan Peninsula from the Austrian border to the Mediterranean Sea. The campaign concluded with the airborne invasion of Cree in late May.
a spectacular tactical success that demonstrated the potential of vertical envelopment, but at a cost so staggering that Hitler forbade large-scale airborne operations for the remainder of the war. German paratroopers suffered over 6,000 casualties, including nearly 4,000 dead. Losses that represented an irreplaceable investment in training and experience.
The elite airborne forces would never again be used in their designed role. It was a victory that felt like defeat. The Balkan campaigns were victories undeniably. German operational art had proven itself yet again multiple opponents simultaneously, but the price was higher than the immediate casualty figures suggested, and the strategic implications were troubling.
The campaigns consumed precious time. Weeks in April and early May 1941, weeks that had originally been allocated for final preparations for the main event, the invasion of the Soviet Union, were instead devoted to crushing Yugoslavia and Greece. Operation Barbarosa, the attack on Russia, had been planned for launch in mid-May.
The Balkan distraction forced postponement until late June. Whether those five or six weeks made the difference between success and failure in Russia remains one of the great counterfactual debates of World War II history. What is certain is that they did not help. The campaigns consumed more than time.
They consumed fuel, ammunition, spare parts. They wore out tanks and trucks on mountain roads never designed for heavy military traffic. They exhausted troops who should have been resting and refitting for the supreme test ahead. Units that fought through the Balkans were not at full strength or full readiness when Barbarasa began.
And the campaigns illustrated a pattern that was becoming fatally clear to anyone who examined the strategic situation honestly. Germany kept winning battles but could not end the war. Each victory seemed to lead not to peace but to another campaign, another front, another set of enemies. Poland had fallen but Britain and France remained at war.
France had fallen, but Britain would not negotiate. Britain could not be invaded. So perhaps the solution was to knock out Russia and thus complete the Continental Empire that would make Germany invincible. Each problem’s solution created new problems. The ring of enemies was not shrinking. If anything, it was growing.
The United States was edging toward active intervention. The war that was supposed to be quick and decisive was becoming long and complicated. But in the summer of 1941, such concerns seemed abstract, almost theoretical. Germany dominated territory from the Arctic Circle to the Mediterranean, from the Atlantic to the borders of the Soviet Union.
The Vermacht appeared invincible. Its methods, speed, coordination, encirclement, shock, had shattered every opponent in less than 2 years. Surely the pattern would continue. Surely the Soviet Union with its officer corps decimated by Stalin’s purges, with its military performance embarrassed in thewinter war against Finland, with its vast territories apparently ripe for the same treatment that had worked against smaller nations.
Surely Russia would fall as quickly as France, perhaps faster. The campaign would be over before winter, the generals promised. 6 weeks, 8 weeks at most. On June 22nd, 1941, Operation Barbarasa began. In the pre-dawn darkness, along a front stretching nearly a thousand miles from the Baltic Sea to the Black Sea, over 3 million German and Axis soldiers attacked the Soviet Union.
Artillery barges of unprecedented intensity fell on Soviet border positions. Luftvafa aircraft destroyed over a thousand Soviet planes on the first day, most of them caught on the ground, lined up wing tip to- wing tip on airfields where commanders had been forbidden to disperse them, lest dispersal be interpreted as a provocative act.
Armored columns poured across the border, pushing deep into Soviet territory before defenders even understood that war had begun. It was the largest military operation in the history of warfare. Nothing in the annals of human conflict had approached this scale. Not Alexander’s conquests, not Napoleon’s Grand Army, not the vast offensives of the First World War.
And in those first weeks, as German forces sliced through Soviet defenses with terrifying efficiency, everything seemed to confirm German expectations and German doctrine. Soviet forces caught off guard by an attack that Stalin had refused to believe was coming despite abundant warnings were shattered. Encirclement after encirclement trapped hundreds of thousands of prisoners.
At Minsk, at Smealinsk, at Kiev, vast Soviet armies were surrounded and destroyed. German tanks raced across the steps, covering distances that made the French campaign look like a limited operation. The speed that had conquered Western Europe seemed to be working again, now on an even grander scale. But there was something different this time, something that would not become fully apparent until later, but was already present from the first days.
The scale was different, not just larger, but qualitatively different in ways that mattered. The distances were measured not in hundreds of kilometers, but in thousands. Supply lines stretched across terrain that fought back. roads that dissolved into bottomless mud in rain that choked tanks with dust in drought that would freeze solid in winter and become impossible in spring thor.
The Soviet Union was not France. It did not have a capital whose fall would mean surrender. A government that would negotiate when the situation became hopeless. A population that might accept occupation as the price of ending the bloodshed. It had space, endless space stretching east beyond the eurals, beyond the reach of any army.
Space into which factories could be relocated, armies could retreat and reform. Resistance could continue indefinitely. And it had something else, a willingness to pay costs that no western nation would contemplate. The Soviet Union would lose more soldiers killed in single battles than Germany lost in entire campaigns.
It would sacrifice cities, populations, entire regions, and keep fighting. The German war machine, optimized for short, decisive campaigns against civilized opponents who would recognize when they were beaten and negotiate rational surrenders, was about to encounter an enemy that operated by entirely different rules.
The autumn rains came. The roads of Western Russia turned into rivers of mud. The infamous Rasputs that had defeated invaders for centuries. Tanks that had raced across France at 40 m a day now sat immobilized, waiting for the ground to freeze. And still Moscow had not fallen. And still the Red Army kept fighting, kept retreating, kept reforming, kept counterattacking with forces that German intelligence said should not exist.
And winter was coming, a Russian winter for which the German army was not prepared because the campaign was supposed to be over before winter arrived. In December 1941, as German forces reached the suburbs of Moscow and could see the spires of the Kremlin through their binoculars, the Soviets launched a massive counteroffensive.
Fresh divisions from Siberia, equipped for winter warfare, slammed into exhausted German troops who lacked proper winter clothing, whose vehicles would not start in the cold, whose weapons froze and jammed. For the first time, the Vermuck was pushed back in significant retreats. The vision of quick victory evaporated in the snow and blood of the Russian winter.
Everything Germany had learned about modern warfare. The tempo, the coordination, the encirclement, the shock, all of it was now being tested on a scale that exceeded its design parameters. The methods that had conquered Western Europe in weeks were failing against an enemy too vast to encircle, too deep to reach, too determined to break.
The speed that had been Germany’s greatest weapon was becoming a trap. The further they advanced, the longer the supplylines, the more vulnerable the flanks, the harder to maintain the very tempo that had made victory possible. The greatest winning streak in modern military history was ending. Not with a single dramatic defeat, but with the slow grinding realization that this war would not be short, would not be decisive, would not follow the pattern of 1939 and 1940.
December 1941, German soldiers stand in the frozen suburbs of Moscow, close enough to see the spires of the Kremlin through their field glasses. They have come over a thousand miles in 6 months. They have destroyed entire Soviet army groups, captured millions of prisoners, occupied territory larger than Western Europe.
By every measure they have used for the past 2 years, they have won. And yet they have not won. The Soviet Union has not surrendered. The Red Army has not collapsed. And now in temperatures that freeze oil in engines and skin to metal, fresh Soviet divisions are counterattacking with a fury that defies everything German intelligence believed possible.
Soldiers who invaded in summer uniforms are dying of frostbite. Tanks that conquered France sit immobilized, their engines dead in the cold. The greatest military machine the world has ever seen is learning a terrible lesson. There are some enemies that cannot be defeated by speed alone. Some distances that cannot be crossed before winter comes.
Some victories that are simply preludes to catastrophe. The winning streak is over. The question now is not whether Germany will conquer the world, but whether Germany can survive what it has started. At Minsk, in the first week of the campaign, German pincers closed around 300,000 Soviet soldiers. At Smealinsk in July, another 300,000 were trapped in a pocket that took weeks to reduce.
At Oman in August, two Soviet armies were surrounded and destroyed, yielding over 100,000 prisoners and enormous quantities of equipment. And then came Kiev in September, the largest encirclement in military history, where over 600,000 Soviet troops comprising multiple armies were trapped when German forces closed the ring. The Kiev encirclement alone produced more prisoners than Germany had captured in the entire Western campaign of 1940.
The numbers were almost incomprehensible, exceeding anything in the prior history of warfare. In the first 5 months of the campaign, Germany captured over 3 million Soviet prisoners of war. These were not small units caught by surprise. These were entire army groups, field armies, core, and divisions swallowed whole by German operations.
The Soviet Air Force, which had been one of the largest in the world, lost aircraft by the thousands, over 20,000 in the first 6 months, a rate of destruction that should have been unsustainable. Tank divisions were annihilated before they could effectively engage. Artillery was captured in position, never having fired.
The speed of the German advance exceeded even the most optimistic planning estimates that staff officers had considered unrealistic. Army Group Center driving toward Moscow along the historic invasion route covered 400 m in the first month, a rate of advance that matched or exceeded anything achieved in the French campaign, sustained over far greater distances and against far larger opposing forces.
German commanders and soldiers experienced a sense of invincibility that seemed confirmed by everyday’s advance. The techniques that had conquered Western Europe were working again. Combined arms coordination between tanks, infantry, aircraft, and artillery shattered Soviet formations before they could organize coherent resistance.
German units exploited gaps, bypassed strong points, drove deep into rear areas, cut communications, and created the same kind of command paralysis they had inflicted on the French. Soviet counterattacks, when they came, were often poorly coordinated, launched peacemeal, and defeated in detail. The Red Army seemed to be doing everything wrong, exactly as German intelligence had predicted.
Hitler declared in early October that the Soviet Union was finished, that the Eastern campaign was essentially won. German newspapers began discussing postwar settlement plans. The foreign ministry prepared for Soviet capitulation. But beneath the surface of these stunning victories, problems were accumulating that would prove fatal.
The first was distance. The Soviet Union was not France. The distances involved were not hundreds of kilometers but thousands. From the German border to Moscow was over 600 m, farther than from the Channel Coast to the Pyrenees. From the border to the Caucasian oil fields was over 1,200 m. German logistics already strained in the relatively compact campaigns in Western Europe began to break down across these vast spaces.
Supply lines stretched impossibly thin. The further German forces advanced, the longer the supply route from rail heads to frontline units, and the Soviet rail network used a different gauge than Europeanrailways, meaning that captured track had to be converted before German trains could use it. A slow, laborintensive process that could not keep pace with the advance.
Trucks already in short supply broke down on roads that were often little more than dirt tracks. In dry weather, dust clogged engines. In rain, mud swallowed vehicles to their axles. German mechanized divisions, the spearheads that had sliced through France, found themselves immobilized for days at a time, waiting for fuel and ammunition that could not reach them.
The second problem was scale. Specifically, the scale of the enemy. Germany had achieved enormous encirclements, had captured millions of prisoners, had destroyed what should have been the entire Soviet military establishment. But the prisoners kept coming. The Soviet Union kept mobilizing.
Divisions that were destroyed were replaced by new divisions. Armies that were encircled were followed by more armies. The German military had no experience with an enemy that could absorb such losses and keep fighting. France had surrendered after 6 weeks and 90,000 dead. The Soviet Union lost more than 90,000 soldiers in single days and did not consider negotiating.
The vastness of Soviet manpower reserves, drawing on a population of nearly 200 million people, meant that the encirclement strategy that had worked so brilliantly in smaller theaters, could not achieve the same decisive results. There was always more enemy behind the enemy you had just destroyed.
The third problem was production, and here German intelligence failed most catastrophically. German assessments had dramatically underestimated Soviet industrial capacity and completely missed the most important development of the campaign’s early months, the massive evacuation of Soviet industry eastward. Beginning in July 1941, as German forces advanced, the Soviet government undertook one of the most remarkable organizational achievements in the history of warfare.
Entire factories, not just the machines, but the workers, the engineers, the raw material stockpiles, the organizational knowledge were dismantled, loaded onto trains, and shipped east beyond the Eural Mountains, beyond the range of German bombers, beyond any possible German advance. Over 1,500 major industrial enterprises were relocated in this manner, including tank factories, aircraft plants, ammunition works, and steel mills.
The chaos was indescribable. Factories set up in open fields, workers living in tents through the Russian winter. Production starting before walls were erected around the machinery. But production started and it increased. By late 1941, Soviet factories in the Eurals and Siberia were producing military equipment at rates that German planners had believed impossible.
The relocated tank factories began turning out T34s, a medium tank that proved superior in almost every meaningful way to Germany’s main battle tanks with better armor, a better gun, better mobility in mud and snow, and a simpler design that allowed mass production on a scale Germany could never match. While German supply lines stretched to breaking across conquered but empty territory, while German factories struggled to replace losses and maintain production, Soviet industrial capacity was not just surviving, but expanding. By 1942, the
Soviet Union was outproducing Germany in tanks, aircraft, and artillery. The material balance that had favored Germany at the campaign’s start was reversing and would continue to reverse with every passing month. The fourth problem was the Soviet soldier himself and the population behind him. German assumptions about Red Army fragility based largely on the poor Soviet performance in the winter war against Finland proved almost entirely wrong.
Soviet troops in those terrible summer months of 1941 often fought with extraordinary determination, even in situations that seemed completely hopeless. Units that should have surrendered according to any rational calculation of military odds continued to resist, tying down German forces that were needed elsewhere, inflicting casualties that mounted day by day, slowing advances that needed to maintain momentum to succeed.
Encircled formations did not always capitulate quietly. Many fought to the last, requiring expensive reduction operations that consumed time and ammunition Germany could not spare. Behind the lines, partisan activity began almost immediately after German occupation, growing in scale and effectiveness. As the occupation continued, resistance fighters attacked supply convoys, cut communication lines, assassinated German officers, sabotaged railways, and forced Germany to divert increasingly large numbers of troops to rear area security
duties. By late 1941, German commanders estimated that hundreds of thousands of troops who should have been at the front were instead guarding supply lines and occupation zones against partisan attack. The anticipated political collapse, subject nationalities risingagainst Russian rule, the communist system disintegrating under military pressure, mass defections and collaborations making occupation easy did not materialize in the way German planners had expected.
Some collaboration occurred particularly in areas like Ukraine and the Baltic states where Soviet rule had been harsh and recent. But German occupation policies, deliberate brutality toward prisoners of war, mass shootings of civilians, starvation policies, the treatment of Slavic peoples as subhuman, stiffened resistance rather than breaking it.
Soviet soldiers and civilians came to understand with terrible clarity that surrender meant death, that cooperation meant exploitation, that the only hope of survival lay in fighting. The choice between resistance and submission became no choice at all. And then came the factor that no planning could have overcome the Russian winter.
German forces had invaded in summer uniforms because the campaign was supposed to be over before winter. When the autumn rains came, bringing the Rasputs, the season of mud that turned roads into impossible quagmires, the advance ground to a halt. When the mud froze and movement became possible again, German forces made one last push toward Moscow in November.
They reached the suburbs, they could see the city, and there they stopped. Temperatures dropped to 40 below zero. Vehicle engines would not start. Weapons froze and jammed. Soldiers suffered frostbite at catastrophic rates. Some divisions lost more men to cold than to enemy action. Horses died by the tens of thousands. And the Soviet Union, which had seemed on the verge of collapse, launched a massive counteroffensive.
The Soviet winter counteroffensive of December 1941 did not destroy the German army, but it shattered forever the myth of German invincibility. Fresh divisions from Siberia, released for transfer west when Soviet intelligence confirmed that Japan would not attack the Soviet Union’s eastern frontier, slammed into German lines with devastating effect.
These were not the poorly led, poorly equipped formations that Germany had been destroying all summer. These were elite troops equipped for winter warfare, trained to fight in conditions that paralyzed their enemies. They wore white camouflage, moved on skis, operated weapons and vehicles designed to function in extreme cold.
Against them stood German soldiers in summer uniforms and standard boots, whose weapons froze, whose vehicles would not start, whose frostbitten fingers could not load ammunition. For the first time in the war, German forces retreated. Not tactical withdrawals as part of larger maneuvers, but genuine retreats.
giving up ground they had spent months and tens of thousands of lives to capture. In some sectors, retreat turned toward route as units that had never experienced defeat simply broke under the combined pressure of Soviet attack and killing cold. Entire divisions lost cohesion. Equipment was abandoned. Positions that had been won at enormous cost were surrendered without serious resistance.
Hitler, in what was arguably the most consequential and arguably correct decision of his military leadership, ordered German forces to hold their positions at all costs rather than retreat into the open steps where they might disintegrate entirely. The standfast order probably saved the German army from complete collapse, though it also resulted in enormous casualties among units that might have escaped encirclement through earlier withdrawal.
The line stabilized barely. The German army survived the winter of 1941 to42, but it was a fundamentally different army now. Battered bled white of experienced soldiers and junior officers, its confidence shattered, its aura of invincibility forever dispelled. The campaign that was supposed to last 8 to 12 weeks had become an open-ended war of attrition against an enemy who simply refused to be decisively defeated.
So, we come to the central question. Why was Hitler so successful in the early years of World War II? Having traced the ark from Poland to the gates of Moscow, having watched victory after victory give way to the first terrible signs of overreach, we can now answer that question with some precision. The answer is not simple because the phenomenon was not simple.
German success in 1939 to41 resulted from the intersection of multiple factors, none of which alone would have been sufficient, but which together created a military advantage that seemed for a time almost supernatural. The first and most important factor was tempo. Germany had developed a way of war that operated faster than its enemies could respond.
This was not primarily about physical speed. German tanks were not notably faster than French tanks. German soldiers did not march faster than Polish soldiers. It was about decision speed. German doctrine, training, and command culture all emphasized rapid action, initiative at every level, and the exploitation of fleetingopportunities.
German officers were trained to act on their own judgment when situations developed faster than orders could arrive. German units could shift direction, exploit breakthroughs, and adapt to changing circumstances in hours rather than days against enemies whose command systems require detailed orders from above, whose doctrine emphasized methodical preparation over rapid action.
This tempo advantage was decisive. Time and again, German forces acted before their enemies could react, seized the initiative, and forced opponents into a reactive posture from which they never recovered. The second factor was combined arms coordination. Germany had integrated its tanks, infantry, artillery, and aircraft into a coherent system that multiplied the effectiveness of each component.
Radio communication, a technology Germany had invested in heavily, allowed real-time coordination between units and between branches. Tanks did not operate alone. They operated with infantry support, artillery preparation, and air cover. All synchronized through a communication network that enemies could not match.
French tanks were often superior to German tanks in individual capabilities. But French tanks operated in isolation without radios, unable to coordinate with each other or with supporting forces. German combined arms teamwork consistently defeated superior individual platforms. The third factor was operational art.
Specifically, the German focus on encirclement and systemic collapse rather than linear advance. German planning thought in terms of campaigns, not just battles. The objective was not to push the enemy back, but to cut him off, surround him, force him to surrender or be destroyed. This required mobile forces capable of deep penetration and Pinser’s movements, which German Panza divisions provided.
But it also required a mental framework that prioritized position over attrition, maneuver over firepower, and decisive action over methodical progress. German commanders were trained to see opportunities for encirclement, to accept risks in pursuit of decisive results, and to exploit success ruthlessly rather than pausing to consolidate.
The fourth factor was enemy weakness, specifically the doctrinal and organizational failures of Germany’s opponents. Poland was caught in an impossible geographic position with an army still transitioning to modern warfare. France, despite massive resources, was trapped in a defensive doctrine designed for the previous war with a command system too slow and too centralized to respond to German tempo.
Britain, though it ultimately survived, was nearly knocked out by the loss of its continental army at Dunkirk. The Soviet Union, despite its enormous resources, suffered from Stalin’s purges, from a rigid command culture that punished initiative, and from a political leadership that refused to believe war was coming until it arrived.
In each case, German strengths were magnified by opponent weaknesses. Speed was most valuable against enemies who were slow. Initiative was most valuable against enemies who waited for orders. Coordination was most valuable against enemies who fought in isolation. The fifth factor was political and moral shock.
German operations were designed not just to defeat enemy armies, but to shatter enemy will. The speed of German advances, the collapse of armies thought invincible, the fall of capitals, the apparent unstoppability of the vermarked. All of this created psychological effects that multiplied military effects. French resistance collapsed not because every French soldier was killed or captured but because the French political system could not absorb the shock of military disaster.
Polish resistance though courageous could not survive the psychological blow of Soviet invasion on top of German attack. The political dimension of German warfare, the exploitation of shock, the targeting of enemy morale, the deliberate creation of panic was as important as the military dimension. The sixth factor was calculated risk backed by luck.
German operations consistently accepted levels of risk that more cautious opponents would never have considered. The Norwegian campaign accepted naval losses that could have crippled Germany if things had gone slightly differently. The Arden’s gamble staked everything on a single throw. If French air power had caught those columns packed on forest roads, the war might have ended differently.
Barbarasa assumed the Soviet Union would collapse before winter with no contingency for what would happen if it did not. In each case, the gamles worked, but they were gamles nonetheless. German success required not just skill, but luck. Good weather at critical moments, enemy mistakes at critical junctures, accidents that favored Germany rather than its opponents.
Luck is not a strategy, but Germany benefited from it repeatedly in the early years. The seventh factor was compounding advantage. Each victory made the nextvictory more likely. Poland’s defeat freed German forces for the western campaign. France’s defeat gave Germany the resources of Western European industry and eliminated the threat of two-front war.
The fall of the Balkans secured Germany’s southern flank for Barbar Roa. Success bred confidence, provided resources, eliminated opponents, and created momentum that seemed unstoppable. German soldiers in 1941 believed they would win because they had won so many times before. German commanders took risks because risks had paid off so often.
The psychology of victory fed on itself until it encountered an enemy that did not fit the pattern. And this brings us to the crucial insight. The very factors that produced early success also produced later failure. The German way of war was optimized for short, decisive campaigns against opponents who would recognize when they were beaten and negotiate surrender.
It was not designed for long wars of attrition against enemies with greater resources and greater resolve. Tempo was devastating against slow opponents. But what happened when the enemy was simply too big to defeat quickly? When there was always more enemy behind the enemy, you had just destroyed. Encirclement worked brilliantly.
when encirclement meant victory. But what happened when you encircled an army of 600,000 and there were still 3 million more soldiers behind it? Risk tolerance produced spectacular successes until the risks finally went wrong. Until the gamble that assumed victory before winter met a winter without victory. Germany’s early success created what we might call the success trap.
Each victory reinforced the belief that the same methods would work again. Each gamble that paid off encouraged the next gamble. The stunning triumphs of 1939 to41 convinced German leadership that they had discovered a formula for victory that could overcome any obstacle. When that formula encountered the Soviet Union, an enemy of unlimited space, unlimited manpower, and unlimited willingness to absorb punishment, the formula failed.
But by then, Germany was committed to a war it could not win through the methods it knew. The speed that had been Germany’s greatest weapon became a trap. The further German forces advanced into Russia, the longer their supply lines, the more exposed their flanks, the more exhausted their troops. The initiative that had won so many campaigns could not be sustained against an enemy who simply refused to be decisively defeated.
The encirclements that had destroyed Polish and French armies were swallowed by Russian space and Russian replacements. The early success of Hitler’s military campaigns was real, was earned, and reflected genuine innovations in the practice of warfare. Germany had developed an approach to modern combat that was genuinely superior to what its early opponents could offer.
The Vermach of 1940 was probably the most effective military instrument in the world at that moment. But effectiveness in short, sharp campaigns against limited opponents did not translate into effectiveness in total war against global coalitions. The skills that won battles did not win the war. The mindset that achieved spectacular early triumphs led directly to the catastrophic overreach of Barbarasa.
In the end, the question is not just why Hitler was so successful in the early years. It is why that success proved so misleading. Why it led to decisions that guaranteed eventual destruction. The winter of 1941 to42 marked the true turning point. The myth of German invincibility died in the snow outside Moscow.
The Soviet Union had survived the worst blow any nation had ever absorbed and was preparing to strike back. The United States, brought into the war by Pearl Harbor in December 1941, was mobilizing industrial resources that would eventually dwarf everything Germany could produce. Britain remained undefeated, its strength growing rather than diminishing.
The war that was supposed to be quick and decisive had become long and attritional, exactly the kind of war Germany could not win. Everything that followed, Stalingrad, Kursk, Normandy, the collapse of the Reich, flowed from what happened in 1941. The decisions made in that year, the successes won and the failures incurred shaped everything that came after.
Germany had gambled everything on one throw of the dice, and the dice had finally come up wrong. There would be years more of fighting, millions more deaths, destruction beyond calculation. But the outcome was no longer in doubt. The question was no longer whether Germany would lose, but when and how many would die before the end.
This is the lesson of the early years, that military success, however spectacular, cannot substitute for strategic wisdom. That speed and initiative, however valuable, have limits that cannot be overcome by will alone. That enemies who refuse to accept defeat, cannot be defeated by methods designed for enemies who surrender when beaten.
that the veryqualities that produce stunning early victories can lead directly to fatal overconfidence and catastrophic overreach. Hitler’s early success was real. It was earned through genuine military innovation, through the development of doctrines and techniques that were genuinely superior to what opponents could offer, through the exploitation of enemy weaknesses, and the calculated acceptance of risks that more cautious leaders would not have taken.
But that success was also the beginning of Germany’s destruction. The methods that conquered Poland and France could not conquer Russia. The tempo that paralyzed smaller opponents could not paralyze an enemy of unlimited space. The encirclements that had destroyed entire national armies could not destroy an enemy who always had more armies behind the ones that had been surrounded.
The lightning that struck so brilliantly across two years, from the plains of Poland to the beaches of Dunkirk to the mountains of Greece, had finally met the one thing it could not overcome. An enemy vast enough to absorb every blow, patient enough to wait for the attacker to exhaust himself, resilient enough to suffer losses that would have broken any Western nation, and determined enough to pay any price whatsoever for survival.
Germany had awakened something that could not be put back to sleep. The age of German victories was ending. The age of German defeats was about to begin. And in 1942, at a city on the bend of the Vulgar River, a city that bore the name of the Soviet dictator who had so catastrophically misjudged the threat in 1941, the world would see the first unmistakable proof that the war had turned. Stalingrad.
The name would become synonymous with catastrophe for German arms, with the moment when the myth of the Vermach died in the rubble and snow of a city that refused to fall. That story, the story of how the tide turned, of how the hunters became the hunted, of how the war came home to Germany itself, is what comes next.
