30 September 1942

The Kokoda campaign turns as small groups of Japanese defenders fight desperate rearguard actions against the advancing Australians.

These small groups hope to hold up the Australian advance sufficiently so that the bulk of their comrades can retreat successfully back their landing beachheads at Buna, Gona and Sanananda, where they have prepared powerful defensive positions.

The Japanese South Seas Force hopes to establish itself safely at the beachheads until HQ in Rabaul can re-supply and reinforce them.
