The camps were founded in April 1945 and remained in existence until September. There was a similar plan for the construction of all the camps. Open farmland close to a village with a railroad line was enclosed with barbed wire and divided into 10 to 20 camps, each housing 5,000 to 10,000 men. Existing field paths were used as streets of the camp and surrounding buildings as the administration, kitchen and hospital. The prisoners of war, forced to surrender their equipment, had to dig holes in the earth by hand in which to sleep.
