Batu Lintang camp (also known as Lintang Barracks and Kuching POW camp) at Kuching, Sarawak on the island of Borneo was a Japanese internment camp during the Second World War. It was unusual in that it housed both Allied prisoners of war (POWs) and civilian internees. The camp, which operated from March 1942 until the liberation of the camp in September 1945, was housed in buildings that were originally British Indian Army barracks. The original area was extended by the Japanese, until it covered about 50 acres (20 hectares). The camp population fluctuated, due to movement of prisoners between camps in Borneo, and as a result of the deaths of the prisoners.
