Comes with C.O.A.

SECRET Australian target map used during Operation Oboe for the assault of North Borneo and the objective of securing the rich Seria oil wells.

This incredibly rare SECRET marked enemy defense map is dated June 1945 was used during Operation Oboe during the Borneo campaign of 1945. Operation Oboe was the last major Allied campaign in the Southwest Pacific Area during World War II to liberate Japanese-held British Borneo and Dutch Borneo. Designated collectively as Operation Oboe, a series of amphibious assaults between 1 May and 21 July were conducted by the Australian I Corps, under Lieutenant-General Leslie Morshead, against Imperial Japanese forces.

The campaign had netted two great naval bases-Brunei Bay and Balikpapan, seven important airfields, the rich Seria-Miri oil wells, the refineries at Lutong, and huge stores of Japanese equipment.

This rare operations target map shows updated Japanese defenses as of June 14th, 1945. The map itself features an incredible legend labeling Japanese bunkers, shelters, foxholes, trenches, AA medium, and AA M.G. of Seria. An amphibious landing was made on 20 June at Lutong, the refinery center for the Seria and Miri oil fields, eighty miles down the coast from Brunei Bay. The uninterrupted advance along the west coast continued toward Seria, 26 miles southwest of Tutong. The Australians reached Seria on 22 June and three days later took Miri, one of the oldest oil fields in Borneo. At Miri, 300 oil wells with a peacetime annual production of 1,318,000 barrels had been set afire by the Japanese and the 600,000-barrel storage tanks had been destroyed. Nevertheless, the capture of the northwest Borneo oil fields had been virtually completed, and Dutch oil experts were soon at work exploiting the vast liquid wealth still underground.

The Australian ground forces were supported by the US and other Allied air and naval forces, with the US providing the bulk of the shipping and logistic support necessary to conduct the operation. The campaign was initially planned to involve six stages, but eventually, landings were undertaken at four locations: Tarakan, Labuan, North Borneo, and Balikpapan.
