context_page_description: The prehistory of Papua New Guinea can be traced to about 60,000 years ago, when people first migrated towards the Australian continent. The written history began when European navigators first sighted New Guinea in the early part of the 17th century.
context_section_description: Shortly after the start of the Pacific War, the island of New Guinea was invaded by the Japanese. Most of West Papua, at that time known as Dutch New Guinea, was occupied, as were large parts of the Territory of New Guinea (the former German New Guinea, which was also under Australian rule after World War I), but Papua was protected to a large extent by its southern location and the near-impassable Owen Stanley Ranges to the north.
  The New Guinea campaign opened with the battles for New Britain and New Ireland in the Territory of New Guinea in 1942. Rabaul, the capital of the Territory was overwhelmed on 22–23 January and was established as a major Japanese base from whence they landed on mainland New Guinea and advanced towards Port Moresby and Australia. Having had their initial effort to capture Port Moresby by a seaborne invasion disrupted by the U.S. Navy in the Battle of the Coral Sea, the Japanese attempted a landward invasion from the north via the Kokoda Trail. From July 1942, a few Australian reserve battalions, many of them very young and untrained, fought a stubborn rearguard action against a Japanese advance along the Kokoda Track, towards Port Moresby, over the rugged Owen Stanley Ranges. Local Papuans, called Fuzzy Wuzzy Angels by the Australians, assisted and escorted injured Australian troops down the Kokoda trail. The militia, worn out and severely depleted by casualties, were relieved in late August by regular troops from the Second Australian Imperial Force, returning from action in the Mediterranean theatre.
  The Japanese were driven back. The bitter Battle of Buna-Gona followed in which Australian and United States forces attacked the main Japanese beachheads in New Guinea, at Buna, Sanananda and Gona. Facing tropical disease, difficult terrain and well constructed Japanese defences, the allies only secured victory with heavy casualties.
  In early September 1942 Japanese marines attacked a strategic Royal Australian Air Force base at Milne Bay, near the eastern tip of Papua. They were beaten back by the Australian Army, and the Battle of Milne Bay is remembered as the first outright defeat on Japanese land forces during World War II. The offensives in Papua and New Guinea of 1943–44 were the single largest series of connected operations ever mounted by the Australian armed forces. The Supreme Commander of operations was the United States General Douglas MacArthur, with Australian General Thomas Blamey taking a direct role in planning and operations being essentially directed by staff at New Guinea Force headquarters in Port Moresby. Bitter fighting continued in New Guinea between the largely Australian force and the Japanese 18th Army based in New Guinea until the Japanese surrender in 1945.
  The New Guinea campaign was a major campaign of the Pacific War. In all, some 200,000 Japanese soldiers, sailors and airmen died during the campaign against approximately 7,000 Australian and 7,000 American service personnel.
