What happened

Japan's South Seas Detachment under Major General Tomitaro Horii landed near Gona and Buna on Papua's north coast on July 21, 1942, intending to cross the Owen Stanley Range on the Kokoda Track and seize Port Moresby, cutting the supply line between Australia and the United States. Australian militia and later Australian Imperial Force troops fought a fighting withdrawal along the single-file jungle track, trading ground for time against a numerically superior Japanese force in some of the harshest terrain of the war, mud, disease, and near-vertical ridgelines. The Japanese reached Ioribaiwa Ridge, about 25 miles from Port Moresby, by mid-September before the loss of Japanese troops at Guadalcanal forced a diversion of resources and a Japanese withdrawal. Australian forces retook Kokoda village on November 2 and cleared the track by November 16.

Why it matters

Kokoda stopped the only serious Japanese attempt to take Port Moresby by land, protecting the staging base the Allies needed for the later New Guinea and Philippines campaigns, and it remains, for Australia, one of the war's most symbolically important campaigns precisely because it was fought defending Australian territory itself. Roughly 625 Australians died on the track and more than 1,600 were wounded, with sickness casualties exceeding 4,000.

How we know
