Bougainville is the largest of the Solomon Islands, near the northern end of that chain, in southwestern Pacific. It is part of Papua New Guinea. Surrounded by cora reefs, Bougainville is 75 miles (120 km) long and 40-60 miles (65-95 km) wide and the northern half of the island is dominated by the Emperor Range, with two active volcanoes reaching 9000ft. The Crown Prince Range occupies the southern half.
Discovered in 1768 and named after its French explorer, it came under German occupation until captured by the Australians in 1914. The Japanese occupied the island early in 1942 and although U.S. troops landing at Kangu Beach had essentially captured it by March 1944, remnants of the Japanese garrison remained until the end of the war.
