After the Allies broke out from Normandy in July 1944, they drove quickly through the rest of France and were threatening the German border by the autumn. To halt the Allies, Hitler’s last throw of the dice was the massive gamble of a counter-attack in the Ardennes.
Sensing the Allies were fatigued, with stretched supply lines after their rapid advance, Hitler presented to his commanders an ambitious plan to force two Panzer armies through the Allied forces, to take the vital port of Antwerp. He intended to exploit the differences between the British and American commands and separate their forces, driving the British to another Dunkirk and buying him time to launch a full-scale assault on Britain with his 'miracle weapons' and undermine the Allies Western alliance.
The massive German attack launched on 16 December 1944 achieved complete surprise but heavy fighting in the American sectors, halted their advance after two days. Known as the Battle of the Bulge because of the bulge in the German lines at this point, a battle of attrition followed in the bitter winter weather but Allied air power and limited fuel supplies on the German side gradually turned the battle in the Allies favour and by mid-January German forces were in retreat. This had been the largest battle fought by the Americans in World War 2 and at the end of it Germany was facing its final defeat.
