After halting the Japanese advance, Allied forces went on the offensive across the SWPA from mid-1943. Australian forces played a key role throughout this offensive, which was designated Operation Cartwheel. In particular, Blamey oversaw a series of highly successful operations around the north-east tip of New Guinea which "was the high point of Australia's experience of operational level command" during the war. After the successful defence of Wau the 3rd Division began advancing towards Salamaua in April 1943. This advance was mounted to divert attention from Lae, which was one of the main objectives of Operation Cartwheel, and proceeded slowly. In late June the 3rd Division was reinforced by the US 162nd Regimental Combat Team, which staged an amphibious landing to the south of Salamaua. The town was eventually captured on 11 September 1943.
