ヘンダーソン基地艦砲射撃
The Japanese determined that the reestablishment of their forces on the east bank of the Matanikau would be prohibitive in terms of the number of troops required to accomplish it. Therefore, the Japanese devised a plan of attack for their scheduled offensive that sent many of their troops on a long and arduous journey to attack the U.S. Lunga perimeter from inland. The march—which began on 16 October—exhausted the Japanese troops involved to such an extent that it was later considered as one of the major factors in the decisive Japanese defeat in the subsequent Battle for Henderson Field from 23–26 October 1942. Thus, the failure of the Japanese to gain and hold a strong position on the Matanikau proved to have lasting strategic consequences in the battle for Guadalcanal, significantly contributing to the ultimate Allied victory in the campaign.
