Allied operations to retake Borneo from the Japanese began on 1 May 1945 with an amphibious landing on Tarakan off the northeast coast of Borneo. This was followed by operations to secure North Borneo, which commenced on 10 June 1945, under the designation Operation Oboe Six. This operation had two phases. In the first, Brigadier Selwyn Porter's 24th Brigade was to secure the island of Labuan and Victor Windeyer's 20th Brigade was to capture Brunei Town. Once these objectives were captured, the region between Brunei Bay and Beaufort on the North Borneo mainland was to be occupied, as was the Miri–Lutong–Seria area of Sarawak. Allied forces would then construct bases in these regions, protect oil and rubber resources and re-establish civil governance.
