Battle of the Bulge 1944–45: Ardennes Offensive, Bastogne & the Allied Response — Complete Field Guide

The German Ardennes offensive of December 1944 was designed to split the Allied armies, cross the Meuse and seize Antwerp before the Western Allies could recover.

The attack began on 16 December against a largely American-held sector. Surprise, poor weather and difficult terrain helped German forces create a deep bulge in the Allied line.

The German plan

Hitler intended armoured forces to drive through the Ardennes toward Antwerp, separating British and Canadian forces in the north from American forces farther south. Fuel, road capacity and the speed of the advance were all critical assumptions.

Surprise

Bad weather initially restricted Allied air power. German units penetrated thinly held sectors and disrupted communications. Some American formations were overrun or forced back.

Bastogne

101st Airborne Division and other US units defended the road hub at Bastogne after German forces surrounded it. The defence complicated German movement but was only one part of a much larger battle.

British command role

As the crisis developed, Eisenhower temporarily placed US First and Ninth Armies north of the German penetration under Montgomery's operational command. British XXX Corps moved toward the Meuse as a reserve, although the main ground fighting remained overwhelmingly American.

Air power returns

When weather improved, Allied aircraft attacked German columns and supply routes. Fuel shortages and road congestion increasingly constrained the offensive.

The offensive fails

German forces never reached the Meuse. Allied counter-attacks reduced the salient through January 1945, leaving Germany with major losses in men, armour and fuel it could not readily replace.
