History
Kaiapit was 45 air-miles northwest of Nadzab and a Japanese force, equivalent to a brigade, moved down the valley in a last-ditch attempt to retake Nadzab. The 2/6th Australian Commando Squadron and B Company Papuan Infantry Battalion arrived at Kaiapit just before the leading elements of the Japanese force. The Japanese fanned out but was quickly routed and they withdrew up the Markham Valley to Dumpu. On September 29, 1943 the Australians entered the Ramu Valley. With Gusap in their hands, the Australians had a valuable advanced airfield and Dumpu was occupied without opposition on October 4, 1943.

Today
Much of the WWII battlefield area was covered over during a natural land slide in the 1980's.
