On 16 December 1944, the Wehrmacht launched its last major offensive campaign of the war. The operation codenamed "Unternehmen Wacht am Rhein", or Battle of the Bulge (16 December 1944 – 25 January 1945), which failed to achieve its objectives, intended to split the British and American Allied line in half, so the Germans could then proceed to encircle and destroy four Allied armies, forcing the Western Allies to negotiate a peace treaty in the Axis Powers' favor.
