The Japanese immediately began to prepare for their next attempt to recapture Henderson Field. The 3rd Battalion, 4th (Aoba) Infantry Regiment had landed at Kamimbo Bay on the western end of Guadalcanal on 11 September, too late to join Kawaguchi's attack. By now, though, the battalion had joined Oka's forces near the Matanikau. Tokyo Express runs by destroyers on 14, 20, 21 and 24 September brought food and ammunition as well as 280 men from the 1st Battalion, Aoba Regiment, to Kamimbo on Guadalcanal. Meanwhile, the Japanese 2nd and 38th Infantry Divisions were transported from the Dutch East Indies to Rabaul beginning on 13 September. The Japanese planned to transport a total of 17,500 troops from these two divisions to Guadalcanal to take part in the next major attack on the Lunga Perimeter set for 20 October 1942.
