Naval Base Borneo

Map of the 1942 American-British-Dutch-Australian Command

To the north, the US Naval Base Philippines fell to Japan before Borneo in 1941 and 1942, as such many US Navy ships and submarines escaped the Philippines and traveled south to ports in Borneo and the Dutch East Indies. On 25 November 1941 knowing that hostile Japan actions in the Pacific was coming, Admiral Hart, commander of the Asiatic Fleet, movef Destroyer Division (DesDiv) 57 (USS Whipple, USS Alden, USS John D. Edwards and Edsall) with the destroyer tender USS Black Hawk, to Balikpapan, Borneo, so the whole fleet would not be at Manila Bay in the Philippines. As Japan advanced south into Borneo these vessels fled further south to form the new US Naval Bases in Australia.[1] Some of the Royal Netherlands Navy vessels, like Netherlands submarines: HMAS K9 and HNLMS K VIII, also fled to bases in Australia.[3] With the American-British-Dutch-Australian Command (ABDACOM) the Allies tried to limit the advance of Japan. ABDACOM did not have enough troops or supplies to carry out the mission. Japan viewed the Dutch East Indies as a prize for its vast quantities of natural resources. In 1941, the Dutch East Indies was a major producer of: rubber, oil, quinine, coffee, tea, cacao, coconut, sugar, pepper, and tobacco. Due to Japan's aggression in China and other places, the US put an oil embargo on Japan.[4][5]

During the Borneo campaign in 1944 and 1945 the Allies both built new bases and used captured Japan bases for staging advances in Borneo and the Philippines.[6] Many ports and cities held by Japan did not surrender until the end of the war.[1][7][8] As the Allies won more battles and moved in on Japan, Japan moved many of the 1942 Prisoners of war, mostly British and Australian in the 1945 Sandakan Death Marches. Like the Bataan Death March of 1942, many died in the Marches.[9][10]

Dutch East Indies became independent from the Netherlands and Japan on 27 December and is now the nation of Indonesia.[11] British Borneo the northern parts of the island of Borneo, became the nation of Brunei on 1 January 1984 and parts became two states in Malaysia.[12] For current base since 1949 see Indonesian Navy.

As in other theaters of war Japan's treatment of POWs and civilians was very poor. Many were exhausted from hunger and disease. Many deaths were caused by the diversion of food, such as rice, to Japanese troops from the Dutch East Indies population. Between 4 and 10 million Indonesians from the Dutch East Indies were turned into Japan's forced labourers, called romusha. Four million died in the Dutch East Indies as a result of famine and forced labour.[39][40]International Red Cross packages were not distributed to POWs.[41][42] In the Dutch East Indies there were both massacres and executions of POWs:[43][44]
