Kokoda Track campaign

Kokoda Track campaign. The campaign was a series of battles fought between July and November 1942 between Japanese and primarily Australian forces along the Kokoda Track in the Territory of Papua. Occurring within the broader South West Pacific Area under the command of Douglas MacArthur, the brutal jungle fighting prevented a Japanese advance on the strategically vital Port Moresby. The successful defence marked a turning point in the Pacific War, halting Japan's southward expansion and boosting Allied morale after a string of defeats.

Background

Following their rapid conquests after the attack on Pearl Harbor, Japanese forces sought to isolate Australia and threaten Allied lines of communication. The Imperial Japanese Navy's attempt to capture Port Moresby by sea was thwarted at the Battle of the Coral Sea in May 1942. This led the Imperial Japanese Army to launch an overland offensive from the north coast of Papua, landing at Gona and aiming to cross the rugged Owen Stanley Range via the Kokoda Track. The Allied commander, General Douglas MacArthur, headquartered in Brisbane, directed Australian Military Forces to defend the territory, with the Papuan Infantry Battalion and local Angau personnel providing crucial reconnaissance and support.

Japanese advance

On 21 July 1942, advance elements of the South Seas Detachment under Major General Tomitarō Horii landed near Gona. They quickly overwhelmed the small Australian garrison at Awala and began their arduous advance inland. After sharp engagements at Kokoda and the disastrous Australian stand at the Battle of Isurava, Japanese forces broke through the mountainous spine of the island. The Battle of Brigade Hill and the Battle of Mission Ridge saw further Australian withdrawals under intense pressure. By mid-September, forward Japanese patrols reached Ioribaiwa Ridge, within sight of the lights of Port Moresby, as the Battle of Milne Bay raged concurrently on the eastern tip of Papua.

Australian defence

The initial defence was conducted by the ill-prepared 39th Battalion and elements of the Papuan Infantry Battalion, later reinforced by the veteran 7th Division returning from the Middle East. Commanded initially by Sydney Rowell and later by Edmund Herring, Australian forces employed delaying tactics along the narrow, muddy track. Critical actions at Efogi, the desperate holding action on Imita Ridge, and the heroic efforts of the Fuzzy Wuzzy Angels were pivotal. The appointment of George Alan Vasey to command the 6th Division brought renewed vigor, as logistical efforts from the United States Army Air Forces and the Royal Australian Air Force improved supply lines.

Allied counter-offensive

With Japanese supply lines overextended and resources diverted to the Guadalcanal campaign, the Allied counter-offensive began in late September 1942. Australian forces, now better supplied and reinforced by United States Army engineers from the 32nd Infantry Division, commenced a relentless advance back over the Owen Stanley Range. They recaptured Ioribaiwa, Kokoda village in a pivotal action on 2 November, and pushed the Japanese back toward their coastal beachheads. This phase involved brutal fighting to dislodge determined defenders from positions like Oivi and Gorari, setting the stage for the subsequent Battle of Buna–Gona.

Aftermath and significance

The campaign concluded with the Japanese forced into a defensive perimeter around their beachheads at Buna, Gona, and Sanananda. Total casualties were high, with Australian forces suffering over 7,000 battle and sickness casualties, while Japanese losses exceeded 12,000. The victory prevented the capture of Port Moresby, securing Australia's northern approaches and protecting the vital sea lanes to the United States. It provided a crucial morale boost for the Allies, demonstrated the fighting prowess of Australian militia and veteran units in jungle warfare, and marked the first major reversal of Japanese land forces in the Pacific, shifting the strategic initiative to the Allies.
