Question

Where did the Germans retreat and what did they begin to build?

Answer 1

During World War II, the Germans retreated to the Atlantic Wall and began building fortified defensive structures along the coasts of occupied Europe. The Atlantic Wall was a series of fortifications designed to defend against an Allied invasion. It stretched from Norway all the way to the Spanish border, heavily fortified with concrete bunkers, gun emplacements, and obstacles to hinder amphibious landings. The Germans also constructed extensive minefields, tank traps, and other obstacles in an attempt to prevent Allied forces from successfully breaching the defenses.
