Ebook: Ruhleben: A Prison Camp Society

"Ruhleben internment camp was a civilian detention camp during World War I. It was located in Ruhleben, then a village 10 km (6.2 mi) to the west of Berlin, now split between the districts of Spandau and Charlottenburg-Wilmersdorf. The camp was originally a horse racecourse ... The camp detainees included male citizens of the Allied Powers living, studying, working or on holiday in Germany at the outbreak of World War I. They also included the crews of several civilian ships stranded in German harbours or captured at sea. There were also quite a number of fishermen captured from trawlers which were sunk in the North Sea in the first days of the war - these were mainly men from Hull, Grimsby and Boston. The camp contained between 4,000 and 5,500 prisoners, most of them British."--Wikipedia.
