<P> During World War II, following the Fall of Singapore in February 1942, the Japanese military detained about 3,000 civilians in Changi Prison, which was built to house only 600 prisoners . The Japanese used the British Army's Selarang Barracks, near the prison, as a prisoner of war camp, holding some 50,000 Allied soldiers, predominantly British and Australian; and from 1943, Dutch civilians brought over by the Japanese from the islands in the Dutch East Indies (now Indonesia). POWs were in fact rarely, if ever, held in the civilian prison . Nevertheless, in the UK, Australia, The Netherlands and elsewhere, the name "Changi" became synonymous with the infamous POW camp nearby . </P> <P> About 850 POWs died during their internment in Changi during the Japanese occupation of Singapore, a relatively low rate compared to the overall death rate of 27% for POWs in Japanese camps . However, many more prisoners died after being transferred from Changi to various labour camps outside Singapore, including the Burma Railway and the Sandakan airfield . </P> <P> Allied POWs, mainly Australians, built a chapel at the prison in 1944 using simple tools and found materials . Stanley Warren of the 15th Regiment, Royal Regiment of Artillery painted a series of murals at the chapel . Another British POW, Sgt . Harry Stodgen built a Christian cross out of a used artillery shell . After the war, the chapel was dismantled and shipped to Australia, while the cross was sent to the UK . The chapel was reconstructed in 1988, and is now located at the Royal Military College, Duntroon, Canberra . </P> <P> After the war, the prison was used to hold former Japanese staff officers, Kempeitai, police, and guards from concentration camps . Executions were conducted in the inner yard where three gallows were erected . British soldiers were stationed there as prison guards . On 17 October 1945, all 260 German seamen of the former U-Boats were moved from Pasir Panjang to the prison . On 26 June 1946, all German soldiers and civilians were notified they would be shipped back to England on a passenger liner, the Empress of Australia . </P>
