Two trails toward the Kumusi

On 21 October 1942, Australian troops who had fought through Templeton’s Crossing on the Kokoda Trail closed on the main Japanese positions at Eora Creek. The clash belonged to a wider Allied effort to cut off Japanese forces withdrawing before the Australian advance. It was not a single-road pursuit: General MacArthur had ordered a coordinated movement on two trails, with the Kumusi River as the intended barrier to retreat.

The Australians moved along the Kokoda Trail. They had taken Efogi and continued toward Myola. From Australia, MacArthur ordered U.S. forces to use the Kapa Kapa Trail, which ran parallel to the Kokoda Trail, in an attempt to trap Japanese troops between the two Allied columns. The plan called for closing their retreat at the Kumusi River. It also included landings on the northern coast between Milne Bay and Cape Nelson, with Wanigela a focus for part of the landing force.

The U.S. troops assigned to the Kapa Kapa route came from the 32nd Division. Elements of the division began moving down the trail, about 30 miles southeast of the Kokoda Trail. The distance between the routes was measurable; the terrain between them was the harder part. The chronology described the ground as very difficult. That mattered to a plan whose purpose depended on two forces advancing in coordination rather than simply moving in the same general direction.

At Templeton’s Crossing, the Australians and Japanese had fought heavily for more than a week before the Japanese fell back toward Eora Creek. The report placed the fighting amid continuing Australian movement on the Kokoda Trail, while the American column pressed along the Kapa Kapa Trail. These were connected efforts, but not interchangeable ones. The Australians applied pressure along the route the Japanese were using to withdraw; the U.S. advance was meant to threaten that withdrawal from the side. The northern-coast landings formed another part of the same effort to close the space available to the Japanese.

The plan’s geography was plain enough: two trails, a river, and a retreat to be blocked. Its execution depended on columns advancing through difficult country and on coastal landings adding pressure elsewhere. MacArthur’s order set out that design. The fighting at Templeton’s Crossing showed the Australian advance meeting resistance on the trail, while the parallel American movement sought to make withdrawal harder. The operation’s neat map logic did not make the ground neat. The two approaches had to converge in effect, even when the terrain kept them apart.
