Main articles: Battle of Borneo (1941–42) and Japanese occupation of British BorneoBorneo was divided into five territories: four in the north under the British – Sarawak, Brunei, Labuan (island), and British North Borneo (now Sabah); and the remainder and bulk of the island to the south under the jurisdiction of the Dutch East Indies (now Indonesia).
The Japanese invasion plan called for the British territories to be taken and held by the Imperial Japanese Army and the southern Dutch territory to be taken and held by the Imperial Japanese Navy.[23] On 8 December 1941, the Brooke government instructed that the oilfields at Miri and Seria and refinery at Lutong be quickly demolished. At dawn on 16 December, two Japanese landing units secured Miri and Seria with little resistance from British forces. A few hours later, Lutong was captured.
