Alsace
On 5 December 1944, the corps moved north against German defenses in the Maginot Line around Bitche. The fighting for the old French forts continued until 20 December 1944. Thereafter, the corps assumed a defensive stance. The corps withstood a fierce German counter-offensive (Operation Nordwind) into Alsace during January, 1945. During this period, XV Corps defended well, restored most of its original position by 7 January 1945, and assumed a defensive stance again until mid-February. From 15 to 23 February 1945, the corps made limited attacks, seizing Forbach, Gros Recherding, and hills south of Saarbrücken. Subsequently, the corps rested and prepared for offensive action designed to breach the Siegfried Line and invade Germany.
