In early 1943, the Australian Army started offensive actions to recapture Lae and Salamaua from the entrenched Japanese. This culminated in the capture of Lae, held by the 7th Division in early September 1943, from a successful combined amphibious landing and airborne offensive. The seaborne assault was notable as it was the first large–scale amphibious operation since Gallipoli. Subsequently, Salamaua was taken days later on 11 September 1943, by a separate joint Australia–US attack. The Battle of Lae was additionally part of the wider Huon Peninsula campaign (September 1943 – January 1944). Following Lae's capture, the Battle of Finschhafen commenced with a relatively swift control of objectives, with subsequent Japanese counterattacks beaten off. On 17 November 1943, a major offensive that began with the Battle of Sattelberg, continued with the Battle of Wareo, and concluded with the Battle of Sio on 15 January 1944, was unleashed. The momentum of this advance was continued by the 8th Brigade, as they pursued the enemy in retreat, which culminated with the Battle of Madang.
