Stalag X-B was a World War II German prisoner-of-war camp located near Sandbostel in Lower Saxony in north-western Germany. Between 1939 and 1945 several hundred thousand POW's of 55 nations passed through the camp. Due to the bad conditions in which they were housed, thousands died there of hunger, disease, or were killed by the guards. Estimates of the number of dead range from 8,000 to 50,000.
