A line of German defense during World War II that crossed the Italian peninsula from the Garigliano in the west through Cassino and then to the Sangro in the east. German forces held the line against the invading Allies from autumn 1943 until May 11-18, 1944, when the line was breached and the Germans retreated into northern Italy.
