The Battle of Balikpapan was the concluding stage of the Operation Oboe. The landings took place on 1 July 1945. The Australian 7th Division, composed of the 18th, 21st and 25th Infantry Brigades, with KNIL troops, made an amphibious landing, codenamed Operation Oboe Two a few miles north of Balikpapan, on the island of Borneo. The landing had been preceded by heavy bombing and shelling by Australian and US air and naval forces. The Japanese were outnumbered and outgunned, but like the other battles of the Pacific War, many of them fought to the death.
