The identity of British soldier Sidney Allen, a native of Cornwall who went missing in action in 1945 during the Second World War, has been established after decades. His grave is located at the Commonwealth War Graves Commission (CWGC) Reichswald Forest cemetery in Germany. The identification resulted from the work of a special unit of the British Ministry of Defence dedicated to locating and identifying fallen soldiers, known as the 'War Detectives'. A reburial dedication ceremony was held in honor of Private Allen, attended by representatives of the military authorities and, presumably, the soldier's relatives. Such ceremonies are conducted to pay tribute to fallen soldiers and to officially recognize their identity many years after the end of the war. Sidney Allen's case adds to the list of Second World War soldiers whose names have been recovered through modern methods of archival research and forensic science. The work of the 'War Detectives' enables the families of the fallen to learn about the fate of their ancestors and receive official confirmation of the location of their final resting place.
