Location
Cause → Event → Consequence
Japanese forces from Major General Tomitaro Horii's South Seas Detachment landed near Buna and Gona in mid-July 1942 with the objective of capturing Port Moresby via the overland Kokoda Track. Preliminary fighting north of Kokoda and around Deniki forced Australian Maroubra Force to fall back to Isurava, where they were reinforced by two veteran Second Australian Imperial Force battalions of the 21st Infantry Brigade.
Between 26 and 31 August 1942, four Australian infantry battalions defended the village of Isurava against a comparably sized Japanese force supported by artillery. Simultaneously, Japanese battalions attempted flanking movements via Abuari and west of Isurava. Lacking their own artillery to counter Japanese bombardment, the Australians held for four days before executing a fighting withdrawal southward.
The Japanese succeeded in capturing Isurava, and Australian forces fell back toward Templeton's Crossing, where further fighting occurred in early September 1942. The battle became central to Australian national memory as a courageous delaying action, though later historical reassessment attributed the successful Australian withdrawal in part to Japanese tactical errors rather than solely to Australian defensive achievement.
