The Siege of Bastogne was an engagement in December 1944 between American and German forces at the Belgian town of Bastogne, as part of the larger Battle of the Bulge. The goal of the German offensive was the harbour at Antwerp. In order to reach it before the Allies could regroup and bring their superior air power to bear, German mechanized forces had to seize the roadways through eastern Belgium. Because all seven main roads in the Ardennes mountain range converged on the small town of Bastogne, control of its crossroads was vital to the German attack.
