The Battle of the Bulge, also known as the Ardennes Offensive and referred to by the Germans as Unternehmen Wacht am Rhein, was an offensive campaign on the Western Front during the Second World War, taking place from 16 December 1944 to 25 January 1945. It was launched through the densely forested Ardennes region of eastern Belgium and northern Luxembourg and was intended to stop Allied use of the Belgian port of Antwerp and to split the Allied lines, allowing the Germans to encircle and destroy each of the four Allied armies and force the western Allies to negotiate a peace treaty in the Axis powers' favor.
