The Battle of Salamaua was an Australian capture of the Japanese supply base at Salamaua in September 1943, during the Second World War. The Japanese launched their attack on Port Moresby over the Kokoda Trail from Salamaua, a seaport on the north coast of New Guinea, and when the attack failed, turned the port into a major supply base. It was eventually attacked by Australian troops flown into Wau, about 40 km away. Japanese reinforcements failed to arrive and the town was taken in September 1943. Research Battle of Salamaua
