The Sandakan Death Marches were a series of forced marches in Borneo from Sandakan to Ranau which resulted in the deaths of 2,434 Allied prisoners of war held captive by the Empire of Japan during the Pacific campaign of World War II at the Sandakan POW Camp, North Borneo. By the end of the war, of all the prisoners who had been incarcerated at Sandakan and Ranau, only six Australians survived, all of whom had escaped. It is widely considered to be the single worst atrocity suffered by Australian servicemen during the Second World War. Background In 1942 and 1943, Australian and British POWs who had been captured at the Battle of Singapore in February 1942 were shipped to North Borneo to construct a military airstrip and prisoner-of-war camps at Sandakan, North Borneo (Sabah). As on the Burma Railway the prisoners were forced to work at gunpoint, and were often beaten whilst also receiving very little food or medical attention. In August 1943, with the intention of controlling the enlisted men by removing any commanders, most officer-ranked prisoners were moved from Sandakan to the Batu Lintang camp at Kuching. Conditions for the remaining prisoners deteriorated sharply following the officers' removal. Rations were further reduced, and sick prisoners were also forced to work on the airstrip. After construction had been completed, the prisoners initially remained at the camp. In January 1945, with approximately 1,900 prisoners still alive, the advancing Allies managed to successfully bomb and destroy the airfield. It was at this time, with Allied landings anticipated shortly, that camp commandant Captain Hoshijima Susumi decided to move the remaining prisoners westward into the mountains to the town of Ranau, a distance of approximately . He claimed that this was an order of Lieutenant General Baba Masao, commanding officer of the 37th Japanese Army. The former military airstrip is now known as Sandakan Airport, which serves Sandakan town. Events The first marches The first phase of marches across wide marshland, dense jungle, and then up the eastern slope of Mount Kinabalu occurred between January and March 1945. The Japanese had selected 470 prisoners who were thought to be fit enough to carry baggage and supplies for the accompanying Japanese battalions relocating to the western coast. In several groups the POWs, all of whom were either malnourished or suffering serious illness, started the journey originally under the intention of reaching Jesselton (Kota Kinabalu).
