On 3 January 1942, Japanese forces captured Labuan unopposed during the Battle of Borneo. The Japanese developed two airfields (Labuan and Timbalai) on the island, which were built by labourers who had been conscripted from the Lawas and Terusan regions of mainland Borneo. The island population was also subjected to harsh occupation policies. After Japanese forces suppressed a revolt at the town of Jesselton in late 1943, which was led by Chinese-ethnic civilians, 131 of the rebels were held on Labuan. Only nine rebels survived to be liberated by Australian forces in 1944. Until mid-1944, few Japanese combat units were stationed in Borneo.
