From Kokoda, the route to Wairopi, and then, to Buna–Gona, was mainly easterly, whereas the advance from Eora Village was mainly to the north. On the main track from Kokoda to Waropi (at the crossing of the Kumusi River) Horii had constructed strong defensive positions, prepared several weeks before. These were centred on the heights overlooking Oivi, with a position in depth at Gorari, which also covered an approach from the southern parallel track. The 41st Regiment, with a battalion of the 144th Regiment and seven artillery pieces faced an advance from the west. Two battalions of the 144th Regiment held the position at Gorari and a track approaching from the south. The force headquarters was to the immediate rear.
