Map contrasting German objectives for the Battle of the Bulge  with the actual furthest extent of penetration. 
 Prelude Initial German assault Allied defense and counteroffensive German counterattack Massacres Background  
The Ardennes Counteroffensive , commonly known as the Battle of the Bulge Nazi Germany  in southern Belgium  and northern Luxembourg  which lasted from 16 December 1944 until 25 January 1945. The intent of the offensive was to split the ground forces of the Western Allies  from each other and encourage them to make peace with Germany, leaving all of Germany's military might to fight off the resurgent USSR . 
The operation was conceived entirely by German head of state and armed forces chief Adolf Hitler . The plan was vigorously opposed by the two ranking generals who would oversee the assault, who saw only a waste of men and material with little chance of success. The Führer dismissed all objections, convinced that the elite German forces would roll over the war-weary and/or inexperienced American formations in the Ardennes Forest  and drive all the way to the English Channel  port of Antwerp . 
In order to mislead any Allied intelligence personnel who might discover the plan, it was given the defensive sounding name Wacht am Rhein , meaning "watch on the Rhine". 
The order of battle presented here reflects a point near the end of the campaign. As with any large army organization in extended combat, forces and their assignments shifted over the course of the battle. For example, when the German attack began on 16 December, the US 7th Armored Division was assigned to XIII Corps, US Ninth Army, 12th Army Group. Later that day, its alignment became VIII Corps, US First Army, 12th Army Group. On 20 December, the alignment switched to XVIII Corps, US First Army, 12th Army Group — and later that day to XVIII Corps, US First Army, 21st Army Group. On 18 January 1945, the alignment changed one last time, to XVIII Corps, US First Army, 12th Army Group — as it is given in the following hierarchy. This OOB  — specifically, at a point near the end of the battle, which lasted from 16 December 1944 until 25 January 1945.

Notes    ^ Both Runstedt and Model were deeply skeptical of the offensive's chances of success, but Hitler ignored all their objections. Runstedt in particular was miffed when he learned that the Allies were referring to the operation as the "Runstedt offensive." [Beevor, p. 82]  ^ Both Runstedt and Model were deeply skeptical of the offensive's chances of success, but Hitler ignored all their objections. [Beevor, p. 82]  ^ In contrast with Manteuffel, Dietrich opened the offensive on his front with a massive artillery bombardment. [Beevor, p. 112]  ^ Manteuffel disregarded Hitler's desire for an opening artillery bombardment; he felt such an action was "a World War I concept and completely out of place in the Ardennes, in view of the thinly held lines," and would only serve to destroy the element of surprise.

[Beevor, p. 112]  ^ Later Oberst Hugo Dempwolff  ^ After the war, served as commandant of the former Palace Hotel (called "Camp Ashcan ") in the Luxembourg town of Mondorf-les-Bains  where high-level German prisoners were kept in the months leading up the Nuremberg Trials .  ^ In England when the German assault began; during the Korean War , provided vigorous leadership to the US Eighth Army , followed by a term as Chief of Staff of the Army .  ^ Private Kurt Vonnegut , later a noted author, was captured while serving in this unit. [Beevor, p. 186]  ^ Regular CO Maj. Gen. Maxwell D. Taylor  was in the United States and his deputy, Brig. Gen. Gerald J. Higgins, was in England; McAuliffe was the divisional artillery commander. [Beevor, p. 154]  ^ The 37th Tank Bttn. was commanded by Lt. Col. Creighton W. Abrams , later commander of all US forces in Vietnam. [Beevor, p. 268]
