Introduction
Background and causes of the Kokoda Track Campaign
Key events of the Kokoda Track Campaign
The Kokoda Track Campaign unfolded through a series of intense engagements between July and November 1942, centred on the march of Japanese forces southward over the Owen Stanley Range and the determined Australian resistance.
Initial advances and early battles
The campaign began in mid-July 1942 when Japanese troops landed near Gona and rapidly advanced towards Kokoda. The Japanese vanguard reached the Kokoda area by the 23rd of July, encountering patrols of the Australian 39th Battalion and the local Papuan Infantry Battalion. After initial skirmishes, the Australians made a stand near Oivi on 26 July but were forced to withdraw to Deniki to avoid encirclement. A small platoon had held Kokoda itself but later retreated to Deniki as well. On 28–29 July, a fierce battle was fought at Kokoda where the Australians were pushed back, and their commanding officer, Colonel Owen, was mortally wounded. This marked a significant early setback for the Australian defenders.
Tactical withdrawal and regrouping
Following the initial Japanese successes, Australian forces regrouped and slowly withdrew to stronger defensive positions further south. Reinforcements from the 39th Battalion arrived overland, and leadership shifted to Major Allan Cameron. An attempted counter-attack on 8 August managed to recapture Kokoda temporarily, but the isolated Australian troops were soon forced to withdraw during the night due to heavy pressure. By mid-August, the Australians conducted a deliberate retreat to the area around Isurava, where they prepared to make a firm stand.
Fierce battles along the track
From mid-August onwards, the campaign was marked by brutal fighting at key points such as Isurava, Eora Creek, and Brigade Hill. Australian troops, despite being outnumbered and facing difficult terrain, held off the Japanese advance through determined resistance and guerrilla tactics. The Battle of Brigade Hill in August was notably important in halting the Japanese progress. As supply lines stretched thin and Japanese troops suffered logistical problems, the tide began to turn.
Turning point and Japanese withdrawal
By late September and October, the momentum shifted firmly to the Australians. Following heavy fighting including the Battle of Ioribaiwa and actions at Eora Creek, the Japanese forces started withdrawing along the Kokoda Track. The Australians pursued, engaging in several sharp skirmishes on the way back to Kokoda Village. By October 1942, Australian troops had retaken Kokoda, marking a decisive shift in the campaign and ending the immediate threat to Port Moresby from an overland advance.
Throughout the campaign, the harsh jungle terrain, difficult supply routes, and tenacious combat defined the struggle along the Kokoda Track, with both sides suffering heavy casualties in a campaign noted for its endurance and determination.
