On April 19, 1943, the Warsaw ghetto uprising began after German troops and police entered the ghetto to deport its surviving inhabitants. Seven hundred and fifty fighters fought the heavily armed and well-trained Germans. The ghetto fighters were able to hold out for nearly a month, but on May 16, 1943, the revolt ended. The Germans had slowly crushed the resistance. Of the more than 56,000 Jews captured, about 7,000 were shot, and the remainder were deported to killing centers or concentration camps.
