Panther–Wotan line

The Panther–Wotan line (German: Panther-Stellung), also known as the Ostwall ("Eastern Wall"), was a defensive line of the Wehrmacht on the Eastern Front of World War II from 1943 to 1944. The Panther–Wotan line ran from the Baltic Sea at Narva in the north, across the western Soviet Union, then along the Dnieper to the Black Sea. It was only partially built by the time the Red Army broke through the line in mid-1944.
