Operation Fall Weiss

Operation Fall Weiss, or Case White, was the German military plan for the invasion of Poland during World War II, initiated on September 1, 1939. This strategy involved a swift and overwhelming attack using Blitzkrieg tactics—combining speed, coordination, and surprise with air and ground forces. The goal was to quickly defeat Polish defenses and seize key cities. The operation marked the start of the war in Europe, leading to the swift defeat of Poland and the subsequent partition of the country between Germany and the Soviet Union. It illustrated the effectiveness of new military tactics that would dominate early WWII.
