101 Miles in 47 Hours — German Generals Said Patton’s Bastogne March Was Physically Impossible

December 19th, 1944. Verdun, France. George Patton has just told Eisenhower he can attack with three divisions in 48 hours, and every professional military officer in the room thinks he is lying. The room is the war room of the Supreme Allied Headquarters Forward Command Element, assembled in emergency session as the scale of the German Ardennes Offensive becomes clear.

Field Marshal von Rundstedt has thrown 250,000 men >> [music] >> and 1,400 tanks through the weakest sector of the Allied line in the early morning darkness of December 16th, and in three days the German advance has achieved the deepest penetration of Allied lines since the Normandy breakout, pushing 25 miles west through the Ardennes, threatening the Meuse River crossings that a German armored force reaching the coast would need to cross, and encircling the town of Bastogne in Belgium with a force that has surrounded the 101st Airborne

Division and elements of the 10th Armored Division in a pocket that the German command is certain will surrender within days. Eisenhower’s commanders are gathered to discuss the response. Field Marshal Montgomery, commanding the 21st Army Group, whose forces hold the northern shoulder of the penetration, General Omar Bradley, commanding the 12th Army Group, whose Army Group has been split by the German advance into northern and southern portions [music] that can no longer coordinate directly, and Patton, who has driven from Nancy to

Verdun through the specific and dangerous roads of a French December in a Jeep whose heating system is inadequate for the temperature, and whose speed is Patton’s characteristically impatient resolution to the inadequacy. The discussion has the specific character of emergency planning whose timelines have been compressed by the operational situation from weeks to days to hours.

The northern shoulder of the German penetration is being held by the American First Army’s units in the Elsenborn Ridge sector. The southern shoulder, the sector from which a relief of the Bastogne garrison must come, if it comes at all, is currently occupied by elements of Patton’s Third Army, who are 75 to 100 miles south of Bastogne, oriented east toward Germany, in the middle of their own offensive operations in Lorraine that have been ongoing since September.

Patton’s claim is not merely that he can redirect this force 90° north and attack toward Bastogne in 48 hours. It is that he can do it in winter conditions, over icy roads, through a German force of unknown size and position, >> [music] >> with three divisions, the Fourth Armored, the 80th Infantry, and the 26th Infantry, that are currently deployed for a completely different operation, and that must be extracted, reoriented, resupplied with ammunition and fuel, configured for a different axis of advance, and committed to contact with the enemy, before the enemy’s

operational timeline produces the Bastogne garrison’s surrender. The professional military officers in the room, who know what army movement at this scale and in these conditions requires, consider the claim operationally impossible, not as a rhetorical characterization of the difficulty, but as a technical assessment of the specific logistics and movement planning that the claim implies.

Moving three divisions from a Lorraine orientation to a northward attack axis in 48 hours >> [music] >> requires a road movement planning exercise whose complexity and whose timeline Patton’s peers in the room have been calculating against the standard logistics parameters that their professional experience has established. How long it takes to move a division size force on a [music] winter road network at winter vehicle speeds.

How long it takes to resupply a division from one axis of advance to another, how long [music] it takes to develop the operational orders and distribute them to every echelon from core to platoon that must execute them, and how long it takes to coordinate the fire support and the air support and the traffic management and the route security that the movement requires.

Every officer in the room has done this calculation for operations of this type. Every officer in the room has arrived at a number significantly larger than 48 hours. They have not spent the last 3 weeks calculating precisely what Patton has spent the last 3 weeks calculating. Have not had access to the contingency plans that Maddox has been developing since December 12.

Have not known that the calculation has already been done and the answer already exists and the orders are already written and have therefore arrived at a conclusion about what 48 hours allows that is technically correct for an army starting from scratch and operationally wrong for an army whose planning has been running since before the crisis began.

George Patton has not arrived at the Verdun war room without preparation. He has arrived with something that military planning culture rarely produces in emergency situations. A plan that already exists in operational detail for exactly the emergency that is being discussed. Beginning December 12 when Third Army intelligence began detecting the build-up of German forces in the Ardennes and when Patton had instructed his operations officer, Brigadier General Halley Maddox, to begin preliminary planning for the eventuality of a German attack in the Ardennes

sector and the necessity of Third Army reorientation. Patton’s G3 section has been developing three contingency plans all oriented toward the northern axis of advance that a Bastogne relief would require. The plans have been developed in secret without informing Army Group or Shaef of their existence because Patton’s operational planning style has always prioritized preparation over announcement and because the specific political and institutional dynamics of the Allied command structure in December 1944 make unapproved contingency planning for

a German offensive that the intelligence community’s official assessment considers unlikely a form of professional heresy that Patton’s instincts have judged the situation warrants regardless. When the Ardennes attack begins on December 16th, Patton instructs Maddox [music] to begin converting the contingency plans from planning documents to operational orders.

By December 19th, when Eisenhower’s emergency session convenes at Verdun in the headquarters building that Patton has arranged for himself in the conference room with the specific and deliberate confidence of a man who is planning to announce a solution rather than participate in a problem discussion, the operational orders for the fourth armored division’s northward movement have already been drafted and are awaiting only the command authority that the Verdun conference will provide to become executive.

Three separate operational plans have been developed for three separate scenarios. Plan A for a turn north at the earliest moment the intelligence suggests the German attack’s axis of effort. Plan B for the turn north assuming a 24-hour delay in the command decision and plan C for a turn north from positions further east than Plan A’s assumptions require.

All three plans have been developed to the level of detail that the operational order format requires. Specific unit assignments, route assignments, time distance calculations for each unit’s movement, fire support coordination, supply arrangements, and the traffic management plan that the simultaneous movement of three divisions on the Belgian road network requires.

The plan that Patton implements on December 19th is plan B, modified by the 24 hours of actual movement data that the first day of execution produces. When Patton tells Eisenhower he can attack with three divisions in 48 hours, he is not making a boast. He is announcing that the plan is already written and the orders are ready to issue.

The specific proof of this is the phone call that Patton makes from the Verdun conference room >> [music] >> in the brief interval between receiving Eisenhower’s authorization to proceed and returning to his seat at the conference table. A call to third Army headquarters in Nancy, in which he delivers a single code word.

The code word that he has prearranged with Maddox to signal that the contingency plan is now an executive order and that the fourth armored division’s movement orders should be transmitted immediately. The call takes 45 [music] seconds. The movement begins within the hour. The German intelligence network monitoring third Army radio traffic will detect the change in signal pattern by the following morning, but will not be able to interpret it accurately because the traffic has been deliberately managed to conceal the reorientation’s

direction for the first critical 12 hours. The operational movement that Patton is planning, the reorientation of three divisions from their Lorraine positions to a northward attack axis toward Bastogne, requires solving in 48 hours a set of military logistics and operational planning problems that the German professional military assessment reviewing the same operational situation from the other side of the line is concluding requires a minimum of five to seven days under the most optimistic assumptions about road conditions,

weather, vehicle availability, and the German defensive force that the third Army will have to fight through on the way to Bastogne. The specific problems are not abstract. Each division must be physically moved from its current position to a new assembly area oriented north rather [music] than east.

The fuel and ammunition that the division has been consuming in the Lorraine offensive must be replaced with fuel and ammunition appropriate for a northward advance through different terrain against a different opponent. The road movement of three divisions on the limited road network of the Belgian Ardennes in December with the same road network simultaneously carrying the supply traffic of the First Army and the movement of the German forces whose interdiction of the roads is one of the operational difficulties the march must

overcome requires traffic management of a complexity that the Third Army’s G-3 section has been planning for since December 12 and whose execution requires the simultaneous and coordinated action of every traffic control element available to the core. The air support coordination must be revised from the east-facing close support patterns that the Lorraine offensive has been using to the north-facing patterns that the Bastogne approach requires.

The medical evacuation system oriented for the Lorraine axis must be reoriented for the Belgian axis. Each of these problems is individually manageable on a timeline of several days. Together in 48 hours they constitute what the German professional assessment has concluded is impossible. The German 47th Panzer Corps under General der Panzertruppen Heinrich Freiherr von Lüttwitz a career panzer officer whose command of armored forces through the Eastern Front’s most demanding operations has given him the specific and extensive baseline for the

assessment of winter armored operations that his December 1944 calculation of the relief timeline reflects is pressing the Bastogne perimeter with four divisions while simultaneously holding the corridor between Bastogne and the Third Army’s position to the south, with the Fifth Parachute Division and elements of the 15th Panzer Grenadier Division.

Forces that the German command believes are sufficient to prevent relief before the garrison’s resistance collapses. Von Luttwitz’s assessment of the relief timeline is built on the standard German military calculation of what an army of this size can achieve in winter conditions on roads whose icing has been degrading vehicle speeds to levels that the movement planning must account for.

A calculation that uses the German Army’s own extensive Eastern Front experience of winter vehicle operations as its baseline. Since the Eastern Front is the theater where the German professional military has accumulated its most extensive and most current data on what armored movement in winter conditions requires and produces. The calculation also incorporates [music] the specific road network analysis of the Ardennes region.

Whose secondary road network the relief force must use because the primary roads are either in German possession or under German direct observation. And whose suitability for armored vehicle movement in December conditions the German engineers on the ground have been assessing in exactly the same way that the Third Army’s engineers are assessing it on the relief force’s side.

The assessment is built on the German Army’s own experience of winter operations in Russia and in the [music] Ardennes. On the specific road network’s capacity for vehicle traffic at winter speeds and on the specific and documented limitations that winter conditions impose on the combined arms coordination that an attacking force requires when the attacking force has been oriented in a different direction and must reorient while under observation.

The German calculation produces the five to seven-day estimate. The German calculation is about to be proved wrong. December 20th, 1944. Arlon, Belgium. The 4th Armored Division, Patton’s spearhead for the Bastogne relief, the formation that in the summer of 1944 has been one of the primary instruments of the 3rd Army’s August advance across France, and that in December 1944 has been fighting in the Saar River sector of the Lorraine offensive.

Combat Command A under Brigadier General Herbert Earnest, and Combat Command B under Brigadier General William Roberts, and Combat Command Reserve under Lieutenant Colonel Creighton Abrams, whose specific assignment is the main effort on the most direct route to Bastogne, is beginning its movement north from its Lorraine positions.

The division’s commanding general, Major General Hugh Gaffey, has been given the mission in a personal meeting with Patton that has produced in Gaffey’s operations section the specific and intense planning activity of a headquarters converting contingency planning to operational reality in the most compressed timeline that military operations permit.

The order of march, the route assignments for each combat command, the artillery positioning for each phase of [music] the advance, the supply schedule for the fuel and ammunition that the advance’s pace will consume, and the specific and critical coordination with the IX Tactical Air Command, whose P-47 Thunderbolts have been providing close air support for the Lorraine offensive, [music] and must be reoriented to the Bastogne approach axis, and briefed on the new operational areas identification procedures [music]

and bomb line positions. All of this is being done simultaneously with the physical movement that it is managing. The conditions are the conditions of the Ardennes winter at their most specific and most demanding. The temperature has dropped below 0° C during [music] the nights and has not risen significantly above it during the days.

The The surfaces that the movement must use are coated with ice, whose specific coefficient of friction is producing vehicle speeds of 15 to 20 mph on secondary roads and under 10 on the most treacherous sections. >> [music] >> And the combination of the German interdiction of the road network and the simultaneous movement of other Third Army units on the same road network is producing traffic congestion at the critical junctions whose resolution requires the specific and disciplined traffic management that the MPs of the Fourth Armored’s traffic control

elements are attempting to provide in conditions that make traffic management a physically dangerous occupation for men standing at road junctions in sub-zero temperatures directing the flow of armored vehicles on iced road surfaces. The tanks themselves, M4 Shermans and M5 light tanks and tank destroyers and half-tracks carrying the armored infantry and the artillery tractors pulling the 105-mm howitzers whose support will be required when the column encounters resistance are moving in conditions that the tanks

track mechanism and the Sherman’s twin parallel tracks have not been specifically designed for. The crews are attempting to compensate with ice chains on some vehicles and none on others, which creates the specific and dangerous situation of a column >> [music] >> in which adjacent vehicles have different effective traction and therefore different cornering capabilities, creating the possibility of rear-end collisions when a vehicle with chains stops in a situation where the following vehicle without chains cannot stop at the same rate. The

specific and chronic problem of vehicles sliding on turns and requiring recovery before the column can continue is being managed by the combat engineers whose M4 dozer tanks are moving with the column specifically for the recovery mission. Men who are working in sub-zero temperatures without the possibility of warming up by returning to a heated space because the heated spaces are not available and the timeline does not permit the stops that warming up would require.

The engine starting difficulties that winter temperatures impose on vehicles that have been running hot from sustained operational use and that must be restarted in the mornings from cold in temperatures that the lubricant specifications have not anticipated [music] as the standard condition of sustained winter operations are being addressed by the maintenance teams who have been keeping their vehicles idling through the coldest hours rather than shutting them down.

Accepting the fuel consumption and the mechanical wear of idling over the certainty of not being able to restart. The Fourth Armored moves anyway. The Fourth Armored moves anyway. The pace is not what Patton wants, but the direction is correct and the intention is absolute. The near failure in the Bastogne relief operation, the moment that comes closest to validating the German professional assessment of the March as impossible and to confirming the timeline that the 47th Panzer Corps has calculated as the minimum required

for relief, arrives on December 22nd at the village of Chaumont, Belgium, where Combat Command R under Lieutenant Colonel Creighton Abrams encounters a German defensive position that the operational planning had assessed as light >> [music] >> and that turns out to be a strong point of the Fifth Parachute Division with anti-tank guns in positions that the approach roads geometry has made effectively impossible to flank and that the available artillery support has been unable to suppress before the leading tank platoons approach.

The lead platoon loses three tanks in the initial engagement >> [music] >> and the response of the combat command’s forward elements, the specific and shock producing experience of an armored advance encountering a defensive position that has been specifically designed to stop exactly this kind of advance on this specific approach road produces a momentary hesitation at the command level that the operational timeline cannot afford.

Abrams has been pushing his command at the pace that Patton’s orders specify and that the operational timeline requires. And the Chaumont engagement is the specific and personal test of whether the pace can be maintained when the pacing counters the specific opposition that it has been warned to expect and that has arrived on the schedule that the operational planning had assessed as most likely.

Abrams makes the decision that the operational situation requires and makes it in the specific and rapid way that a commander who has been making these decisions under pressure for 7 days makes decisions that the organizational doctrine has trained him to make without waiting for higher command confirmation, without requesting clarification of the operational order, without the specific delay that passing a significant tactical decision up the chain and waiting for the response would impose on a timeline that measures its margin in

hours rather than days. He flanks Chaumont with Combat Command A’s elements moving on an alternate route that the map and the available engineer reconnaissance have identified as passable for tracked vehicles if not for the wheeled support elements that will have to follow on the primary route once it is cleared.

He continues the advance with Combat Command R on the primary route after the flanking movement has disrupted the German defensive positions command and supply connection to the main defensive line. And he continues to Bastogne at the pace that the reorientation of the flanking movement allows rather than the pace that the direct advance would have permitted.

A pace that is slower than the direct advance would have produced but faster than the German defensive position at Chaumont would have permitted the direct advance to achieve. The delay is measured in hours. The advance continues. The delay is measured in hours. The advance continues. December 26th, 1944. 16:45 hours.

The lead tanks of Combat Command A, 4th Armored Division, crack through the last German defensive position south of Bastogne at the village of Assenois and make contact with the 101st Airborne Division’s perimeter. Lieutenant Colonel Creighton Abrams, the man who will eventually command the United States Army in Vietnam and whose name will be given to the tank that the Army builds after the lessons of the Second World War and the Cold War have been incorporated into the American armored doctrine that the Second World War has produced, is in the

lead vehicle personally directing the break through in the specific and documented way of a commander who understands that the last mile of this march [music] requires the same direct command presence that the first mile has required. His M4 Sherman is at the front of Combat Command A’s column as it approaches Assenois.

Not because the regimental command doctrine prescribes that the commanding officer should be in a position to be killed by the first anti-tank gun the column encounters, but because the operational situation of December 26th, 1944, the specific operational situation of a force that is breaking through the last German defensive position between itself and the garrison it has been moving toward for 7 days, is the operational situation in which the presence of the commander at the point of decision is the most important single element of

what the decision-making process requires. Abrams is making the decisions as the situation produces them rather than waiting for the situation to report back through the chain. The road into Bastogne is open. The garrison that the German command has been certain would surrender within days, within the specific timeline that the German High Command’s assessment of the 101st Airborne supply situation and the pace of the relief forces movement has established as the outer limit of the garrison’s ability to continue organized

resistance has not surrendered. The 101st Airborne under Brigadier General Anthony McAuliffe, who has famously responded to a German surrender demand with the single word “Nuts” on December 22nd, a response that the German officers receiving it have to have translated by an American-educated German officer who explains that it means the same as the German equivalent of a specific and profane refusal, holding a perimeter of approximately 10 mi in circumference against four German divisions pressing from all directions

with ammunition running low to the point where the artillery battalions are rationing shells per gun per day to single digits, medical supplies exhausted to the point where the aid stations are using German surgical dressings captured from supply vehicles the garrison has intercepted, and the specific [music] cold of the Ardennes winter producing in the men holding the foxholes a form of physical suffering that the word cold does not adequately describe, [music] the kind of cold that freezes the lubricant in the rifle mechanism and

requires firing the weapon to melt it before the next shot is possible, the kind of cold that kills the wounded who cannot be moved to shelter before their core temperature drops below the survivable threshold >> [music] >> has held, and Patton has delivered what he promised Eisenhower in the Verdun war room 7 days ago.

The German professional assessment of the Bastogne march as impossibility is documented in the Foreign Military Studies interviews that the Army Historical Division conducts with senior German officers in the years following the war. General Heinrich von Lüttwitz, who commanded the 47th Panzer Corps, whose forces the March defeats, provides in his interview the most detailed German professional assessment of what the Third Army accomplished between December 19 and December 26, that the movement of a core-sized force with its

supporting artillery and logistics and the air support coordination that the March’s operational direction change requires from a Lorraine orientation to a northward Ardennes attack in the time period that Patton has achieved is a feat that the German professional calculation had concluded was not achievable under the conditions of December 1944.

He does not offer this assessment as an excuse. He offers it as a professional analysis of an opponent’s performance whose accuracy he has been compelled by the evidence to acknowledge. The March distances vary across accounts. The Fourth Armored Division’s different combat commands traveled different distances from different starting positions, and the measurement of road distance through the Ardennes network produces different numbers depending on which element’s movement is being measured and which waypoints are being

counted. The general scale, 75 to 100 miles in 48 to 72 hours in winter conditions culminating in a combat breakthrough, is consistent across the accounts. And that scale is what von Luttwitz’s assessment declares impossible. A force of this size in these conditions moving on this timeline is in the documented assessment of the German professional military observers who faced it, a performance without precedent in the winter operations of a war that has been producing winter operations since December 1941 on the Eastern Front, and that has

therefore produced in the German professional military’s experience a specific and extensive baseline for what winter operations in comparable conditions require. The Eastern Front has produced winter marches of extraordinary endurance by forces operating at the extreme limits of human physical capacity.

The German winter withdrawals of 1941 and 1942, conducted by men who had been fighting continuously and who were simultaneously moving and fighting in temperatures that killed the inadequately clothed and the inadequately fed at rates that the military casualty records document separately from combat losses. None of them has been conducted with the organizational coherence and the operational effectiveness at the end point that the Fourth Armored Division’s arrival at Bastogne demonstrates.

The men who arrive at Assenois on December 26th are not men who have exhausted themselves in a desperate march [music] and can now only await relief. They are men who have fought their way through a German defensive force that has had five days to prepare positions on the route of the march. Positions at Chaumont and Remichampagne and Vaux le Rozier and the approaches to Assenois itself that each required its own tactical solution and each produced its own delay and its own casualties [music] and who arrive at the breakthrough point

with the residual combat effectiveness to complete the operation. This is what the German professional assessment calls impossible. It is not impossible. It is planned. It is what Patton has been planning since December 12th. The Bastogne garrison that Abrams reaches on December 26th has been holding for 10 days against the German pressure that the 47th Panzer Corps has been applying with four divisions and that the German command has been certain will [music] produce the garrison’s surrender before any relief could arrive. The 101st

Airborne’s 11,840 men have held a 10-mi perimeter with approximately 300 artillery rounds per gun remaining on the morning of December 26th, enough for perhaps one more day of the defensive fire rate that the German infantry assaults have been requiring. The December 23rd clearing of the weather has allowed air supply drops to reach the garrison.

241 tons of supplies delivered by 241 C-47 aircraft on December 23 and December 24th, enough to sustain the defense, but not enough to replenish it to the levels that would allow indefinite resistance. The garrison’s medical situation has been described by its surgeons as catastrophic. No anesthesia, minimal surgical supplies, the wounded being held in facilities designed for non-combat administrative functions and receiving care at the level of what is available, rather than what the wounds require. The road that Abrams has opened

on December 26th is the road that changes all of this. The legacy of the Bastogne relief march is not primarily a legacy about Patton’s genius or about American military excellence or even about the operational achievements, specific and documented technical qualities. It is a legacy about the specific relationship between planning and opportunity, about the specific and rare combination of conditions that produces the moment when an impossible thing becomes possible, and about the specific and unusual combination of

institutional qualities that allows those conditions to be met. The advance preparation that exists before the crisis requires it. Patton’s contingency planning from December 12th, invisible to the chain of command and therefore unavailable to the institutional approval process, whose timeline would not have permitted the planning to be completed before the crisis arrived.

The command authority that is willing to commit to a course of action on incomplete information, Eisenhower’s authorization at the Verdun conference, given to a general whose claim of 48-hour readiness, the professional military officers in the room have considered impossible, and whose institutional track record has given Eisenhower the specific and hard-won trust that allows the authorization to proceed without the verification that normal operational planning requires.

The command culture that pushes decision-making to the lowest level at which the decision can be effectively made, and that therefore allows a Creighton Abrams to make the call at Chaumont that preserves the operational timeline, rather than waiting for the decision to be made at the core level, where the timeline’s pressure is less directly felt.

And trust, the specific and institutional trust that allows Patton to stand in the Verdun war room on December 19th and tell Eisenhower he will attack with three divisions in 48 hours without showing Eisenhower the planning documents that justify the claim. Because the claim is specific enough, and the institutional relationship is secure enough, that the claim itself is the justification.

The German generals who assessed the Bastogne march as physically impossible were wrong. Not because they misunderstood the physics of winter operations or the logistics of armored movement. They were wrong because they had no framework for an opponent who had been planning for the crisis 3 days before the crisis began, who had the operational orders written before the command authority had been given, and who was therefore not operating on the timeline that winter conditions and road networks [music] and German defensive positions impose on armies

that begin planning when the crisis arrives. Patton began planning when the intelligence suggested the crisis was coming. That is the difference between what the German assessment projected and what Patton delivered. That is the 48 hours that the German generals said no army could find. He had been finding them since December 12th [music] in the contingency planning that his professional instincts and his intelligence officers warnings had led him to initiate before the command authority that would authorize the

planning had been given. In the specific and quiet work of a planning staff turning an anticipated crisis [music] into a prepared response before the crisis had officially arrived in the institutional courage of a general who was willing to plan for a contingency that his superiors had not authorized him to plan for because the contingency was coming regardless of whether it had been authorized.

[music] The march was physically possible. Patton had been proving it since December 12th 7 days before he stood in the Verdun war room and announced that he would attack in 48 hours because the 48 hours that the professional military officers in the room considered impossible was the 48 hours that he had spent the previous week turning from a military calculation into a military plan and a plan when it already exists is not an impossibility.

It is an order waiting to be issued.
