The Battle of Madang, fought between early February and late April 1944, was the break-out and pursuit phase of the Markham and Ramu Valley – Finisterre Range and Huon Peninsula campaigns, which were part of the wider New Guinea campaign of World War II. After overcoming the Japanese defences around Shaggy Ridge, the Australian forces descended the steep slopes of the Finisterre Range and pursued the withdrawing Japanese towards Bogadjim and then Madang on the north coast of New Guinea. There they linked up with US and Australian forces that had advanced along the coast from the Huon Peninsula, while the remnants of three Japanese divisions withdrew towards Wewak, where further fighting would take place throughout late 1944 and into 1945.

The Markham Valley, Ramu Valley and Finisterre Range campaigns were a series of battles within the broader New Guinea campaign of World War II. The campaigns began with an Allied offensive in the Ramu Valley, from 19 September 1943, and concluded when Allied troops entered Madang on 24 April 1944. During the campaign, Australian forces – supported by Australian and US aircraft – advanced through the Markham Valley and Ramu Valleys during which there were minor clashes with Japanese forces, which withdrew towards their main defensive line in the Finisterre Range.
