The plan had been conceived in secrecy and delivered to the generals who would execute it with the force of a command that admitted no professional objection. Adolf Hitler had assembled the senior commanders of the Western Front at his headquarters in late November 1944 and unveiled the operational design that he had been developing since September.

 An armored thrust through the Arden forest in Belgium and Luxembourg. The same terrain through which the spectacular May 1940 offensive had cut the Allied armies in two, driving northwest to the Muse River and then beyond to Antwerp, the great port city whose capture would split the Allied armies and cut off the British and Canadian forces in the north from their American counterparts in the south.

 The operation would be called Watch on the Rine, and Hitler presented it with the conviction of a man who believed that the circumstances of 1940 could be recreated in 1944, as though the four years between them had not occurred, and as though the German army of December 1944 was the German army of May 1940. The generals listened.

 Field Marshal Gear von Runstead, recalled from retirement for the second time to serve as commanderin-chief West, sat through the briefing with the expression of a man who had heard too many impossible plans delivered with total certainty to show his reaction on his face. He was 69 years old and had spent the war managing the tension between his professional judgment and the commands of a supreme leader whose strategic instincts he had respected in the early years and had come to regard with increasing dismay as the war turned against Germany.

Runstead understood immediately that the plan was beyond the capacity of the forces available to execute it. That reaching Antwerp, some 250 km from the start line through terrain that would channel the advancing columns into narrow roads and expose their flanks to counterattack required a German army that had not existed since 1942.

He said nothing that would constitute direct opposition in Hitler’s presence because direct opposition to Hitler’s strategic concepts had destroyed the careers of better men than him and instead privately described the plan to his staff as an enormous bluff whose only realistic objective was to reach the muse and hope that the shock of the offensive would produce some political result that the military result alone could not achieve.

Field Marshal Walter Model, commanding Army Group B, the formation that would actually execute the offensive, was a different kind of general from Runstead. Where Runstead was aristocratic and professionally reserved, model was aggressive and operationally creative. The officer Hitler had called his firefighter for his ability to stabilize desperate defensive situations on the Eastern Front through sheer force of will and tactical improvisation.

Model had genuine military talent and genuine loyalty to the regime. And he examined the Arden plan with the eyes of an officer who wanted it to succeed and who was honest enough with himself to see that it could not succeed in the form Hitler had prescribed. He proposed a scaled down version, a smaller offensive with a shallower objective designed to destroy Allied forces in the Arden rather than reach Antworp, an operation proportion to the actual resources available rather than the resources the plan required. Hitler

rejected the modification and ordered the original plan executed in full. The forces assembled for the offensive represented Germany’s last significant operational reserve in the west. The sixth SS Panza army under SS Obus Grupenfura Sepitrich was the strongest formation committed to the attack with four SS Panza divisions that had been refitted and rearmed specifically for this operation.

The fifth Panza army under General Hasso Fon Mantofl, a gifted armored commander who had distinguished himself on the eastern front, was assigned the central sector. The seventh army under General Eric Brandenburgger, a standard infantry formation with limited armor, was tasked with protecting the southern flank of the offensive.

 Together, these formations represented the largest single concentration of German military power assembled in the West since the Normandy battles, and they had been gathered at enormous cost to other sectors of the front, stripped from positions where their absence would be felt as immediate tactical vulnerability. The fuel situation was understood to be critical before the offensive began.

 The German planning assumed that the advancing forces would capture Allied fuel dumps in the forward areas, an assumption that contained within it an acknowledgment of German logistical insufficiency. The admission that the operation could not sustain itself on fuel it brought to the start line and would need to live off the enemy’s supply system to reach its objectives.

The assumption was not irrational given the scale of Allied logistics in the west where forward fuel dumps of the kind that would service the armored columns driving toward Antworp did exist and were sometimes lightly guarded. But it was an assumption that made the entire operation dependent on a specific tactical success.

 the rapid capture of those dumps that could not be guaranteed and that if it failed to materialize in the first days of the advance would strand the armored columns on roads they had no fuel to travel. The offensive began on December 16th, 1944 with an artillery preparation along an 80 km front that achieved the surprise the planners had been hoping for.

 The American units holding the Arden sector had been thinly positioned precisely because the terrain was considered unsuitable for major offensive operations. The same assessment of the Arden that had made the French position there so vulnerable in 1940 and the initial German assault struck formations that were either newly arrived in the theater and still finding their footing or exhausted units that had been sent to the quiet sector to rest.

The results in the first days were dramatic enough to create at Hitler’s headquarters the brief intoxication of apparent success that had characterized the early phases of Barbarosa and several subsequent German offensives before reality reasserted itself. The tanks of Yakim Piper’s camp grouper operating as the spearhead of the sixth SS Panza army drove deep into the American rear area with a speed that created genuine alarm at Allied headquarters and established Piper’s name in the history of the battle as the

embodiment of what the German offensive had briefly threatened to accomplish. But Piper’s column was driving on a single road through terrain that offered no alternative routes for the heavy vehicles and supply trucks that a sustained armored advance required. And the fuel situation that had been critical before the offensive began, became acute almost immediately.

American units ahead of Piper’s column, conducting the rapid demolitions and defensive actions that the shock of the initial assault had not prevented them from organizing, destroyed fuel dumps that Piper’s tanks needed to continue their advance and blocked road junctions that the routting of his column could not bypass in the constricted terrain.

The generals who were closest to the actual fighting, the division and core commanders whose formations were driving into the Allied positions and measuring the resistance against their available strength, began understanding within the first 72 hours of the offensive that the plan was not developing as Hitler had prescribed.

 General Fonantul’s fifth Panza army was making better progress than Dietrich’s sixth SS whose axis of advance had been planned as the operation’s main effort but whose actual performance was being slowed by the same combination of road conditions fuel shortages and stiffening American resistance that was constraining every formation in the advancing line.

Monturfl was an officer of genuine operational skill who drove his formations with aggressive intelligence rather than the bureaucratic compliance that characterized some senior German commanders. And he recognized quickly that the operation’s center of gravity was shifting from Dietrich sector to his own.

 that if the offensive had any realistic chance of achieving even its limited intermediate objectives, the fifth Panza army was more likely than the sixth SS to achieve them. The town of Bastonia became the operational problem that the German advance could not solve. And the problem it could not solve was the clearest possible demonstration of why the offensive was failing.

 Bastonia sat at the junction of seven roads through the Arden and in the terrain of the Arden, where the forests and the ridgeel lines channeled all movement onto the existing road network. A town that controlled seven roads controlled the movement of everything in its vicinity. The German operational plan had assumed that Bastonia could be bypassed and taken later, that the momentum of the advance would render its garrison irrelevant, that the speed of the German armored thrust would prevent the Americans from reinforcing the town before it became untenable.

The assumption was wrong. The 101st Airborne Division rushed from its rest area at Rams and arriving in Baston just ahead of the encircling German forces turned the town into a fortress that the German formations could neither reduce nor safely bypass because the road network it controlled was the road network that the German supply columns needed to sustain the advance beyond it.

General Hinrich von Llutvitz, commanding the 47th Panza Corps, whose formation surrounded Bastonia, sent the famous demand for surrender to the American commander, Brigadier General Anthony McAuliffe on December 22nd. And McAlliff’s equally famous one-word response, nuts, communicated in the most economical possible form what the American position was.

 But the significance of the exchange was not primarily in its rhetorical memorability. It was in what it revealed about the German operational situation, that a German core was investing a single American town and demanding its surrender rather than driving past it. That the momentum of the offensive had been arrested before it had reached the muse.

 That the timetable on which the entire plan rested was already beyond recovery. Model understood this before Lutvitz sent his demand. He was driving himself through the battlefield with the relentless personal presence that characterized his command style, visiting formations, questioning commanders, measuring the gap between the operational orders and the operational reality with the professional honesty that made him, whatever his other qualities, a genuinely useful instrument of assessment.

What he was measuring in the last days of December was the progressive deterioration of the German armored formations, the declining fuel, the tank losses that could not be replaced, the infantry casualties that were hollowing out the division’s fighting strength, the weather that had grounded the Luftwaffer and would when it cleared exposed the German columns to Allied air power that had been waiting for visibility to operate.

The weather cleared on December 23rd, and Allied air power returned to the battlefield with an effect that the German generals had known was coming, and that hit the advancing columns with a force that made the preceding week’s difficulties appear manageable by comparison. American P47 Thunderbolts and P-51 Mustangs and medium bombers hit the German supply columns on the roads through the Arden with the accumulated fury of a week’s worth of missions that the weather had prevented them from flying. And the supply system that was

already inadequate became catastrophically worse as the vehicles and the fuel and the ammunition that the advancing formations needed were destroyed on the roads before they reached the front. Runstead watched the reports arriving at his headquarters with the resigned clarity of a man whose professional assessment had been correct and whose correctness had cost him nothing except the knowledge that he had been right.

 while being required to execute the plan he had known would fail. He was not in operational control of the offensive in any meaningful sense. Model commanded Army Group B and Hitler commanded the strategic concept and Runstead’s role was largely ceremonial, a senior presence whose reputation provided the operation with the legitimacy that his actual authority did not match.

 But the reports crossing his headquarters told a story that needed no professional analysis to read. The offensive had failed to reach the muse. The fuel was running out. The Allied counterattack that Patton was organizing from the south was developing faster than the German defensive arrangements in that sector could absorb. and the formations that had been committed to the attack had taken losses that would leave the western front weaker after the offensive than before it.

General Patton’s third army began its counterattack on December 22nd, turning 90° in the middle of a winter campaign and driving north toward Bastonia with a speed that German operational planning had not fully credited as possible. The logistics of turning three army corps in the middle of an active campaign and reorienting their axis of advance by 90° within 72 hours was an achievement that German staff officers assessing the Allied capability before the offensive began had rated as unlikely under realistic conditions.

Patton executed it, and by December 26th, his leading armor had broken through to Bastonia and relieved the garrison, eliminating the operational problem that had been consuming German strength since the encirclement began and restoring the road junction to Allied use. Seb Dietrich commanding the sixth SS Panza army was not a professional staff officer in the sense that Mantto or model were professional staff officers.

He was a Nazi loyalist whose senior command had been given to him for political reasons rather than professional qualifications, and his operational management of his formations reflected the limitations of a man whose military instincts had not been refined by the systematic training of the German staff system.

 His army’s performance in the Arden had been the offensive’s greatest disappointment, the main effort that had not become the main effort. And by late December, he was reporting to model with an honesty about his formation’s condition that the circumstances no longer allowed him to disguise. The Panza divisions that had been the offensive central striking power were depleted in tanks and fuel and infantry to the point where offensive action on the scale the operational plan required was no longer possible.

Hitler received the reports of the offensive developing failure at his headquarters with responses that had become the signature of his command in the final year of the war. Rage at the commander responsible insistence that the objectives were still achievable with sufficient will orders for counterattacks that the available forces could not execute.

 He ordered the sixth SS Panza army to continue its advance to the muse. At the same moment that Dietrich was reporting that his forward divisions had no fuel to move. He ordered Bastonia retaken at the same moment that Patton’s armor was consolidating the corridor that his relief column had opened. He ordered the southern flank held against Patton’s counteroffensive with forces that the attrition of the preceding 10 days had reduced to fractions of their nominal strength.

The generals executing these orders were men who had spent varying amounts of time learning how to operate in the gap between what Hitler’s commands required and what the actual situation permitted, and who had developed varying degrees of skill at maintaining the forms of compliance while managing the practical impossibility of the substance.

Model was the most skilled at this navigation. He had been performing it since his days as a core commander on the Eastern front and had refined it into something approaching an art and he used his freedom of movement through the battlefield to make the adjustments that the situation required without framing them to Hitler as the retreats and withdrawals that they actually were.

Mantofl was similarly pragmatic, managing his formation’s retirement from the deepest points of the penetration with the professionalism that preserved their coherence for the defensive fighting that he understood was the only remaining mission the western front could realistically perform. The German armies withdrew from the Ardens through January 1945, pressed by American forces on three sides and constrained by Hitler’s orders to hold positions that the fuel and ammunition situation made holding impossible. The formations that

came out of the bulge were smaller than the formations that had gone in. Their equipment losses replaced by nothing. Their infantry strength reduced by casualties that the replacement system could not make good. Their senior leadership exhausted by weeks of the most demanding operational management under the worst possible conditions of weather and supply and command.

 Runet assessed the situation on the Western Front after the Arden’s offensive in the language of professional bleakness that his position entitled him to use in private communications to his own staff. The last significant reserve of German offensive power in the west had been committed and consumed.

 The rine which might have been defended with the forces that had been expended in the Ardens was now to be defended with what remained after the Ardens had taken what it took. The Allied armies pressing from the west had absorbed the shock of the German offensive, recovered their balance, and were now advancing with the confidence of forces that understood they were fighting an opponent that had shown its last card.

 The generals, who had sat in Hitler’s briefing room in November 1944, and heard the Antwer plan delivered with total certainty, had known, most of them, what the outcome was likely to be. They had known it from the forceto space ratios and the fuel calculations and the road network analysis and all the other tools of professional military assessment that the German general staff had refined over generations of institutional development.

 They had executed the plan anyway because the command structure they operated within did not permit the honest professional response that the assessment demanded and the execution had consumed the resources that might have extended the war’s conclusion by months while changing nothing about its direction. The Battle of the Bulge was the last time the German army in the West mounted a major offensive operation.

 After January 1945, it defended and then it retreated and then it surrendered. and the generals who had known it was hopeless before it began, lived to write their memoirs in Allied captivity, and explain in careful professional language why they had been right, and what had prevented them from saying so at the time when saying so might have mattered.
