In World War II, the city again suffered significant damage, and Nazi Germany occupied it from 19 September 1941 to 6 November 1943. Axis forces killed or captured more than 600,000 Soviet soldiers in the great encirclement Battle of Kyiv in 1941. Most of those captured never returned alive. Shortly after the Wehrmacht occupied the city, a team of NKVD officers who had remained hidden dynamited most of the buildings on the Khreshchatyk, the main street of the city, where German military and civil authorities had occupied most of the buildings; the buildings burned for days and 25,000 people were left homeless.
