The Battle of Roosevelt Ridge was fought between 21 July and 14 August 1943 between U.S. and Japanese forces in the Salamaua area of the Territory of New Guinea during World War II. The battle was fought in conjunction with several other actions of the Salamaua–Lae campaign. Throughout the first half of 1943, Australian forces had clashed with the Japanese around Wau and then Mubo as they had pushed the Japanese back towards Salamaua. As the campaign had developed, the Japanese had brought in reinforcements from elsewhere in New Guinea, effectively reducing their garrison, particularly around Lae. Following fighting on Lababia Ridge, the Australians had begun securing positions around Bobdubi, with a view to extending towards Mount Tambu. With a view to driving on Salamaua from several different axes, and also to establish a port with which to relieve the aircraft and native carriers that were supplying their forces, a landing at Nassau Bay was made in early July by US troops, and they subsequently began a drive north along the coast.
