Built as a series of forts, bunkers, and tank traps, the West Wall--known as the Siegfried Line to the Allies--stretched along Germany's western border. After D-Day in June 1944, as the Allies raced across France and threatened to pierce into the Reich, the Germans fell back on the West Wall. In desperate fighting--among the war's worst--the Germans held off the Allies for several months.
