The other relocated battalion, the 1st Battalion, 5th Marine Regiment (1/5), was landed by boat west of the Matanikau near Kokumbuna village on 27 August with the mission of attacking Japanese units in the area, much as in the first Matanikau action of 19 August.
Den anden overførte bataljon, 1. bataljon af 5. marineregiment, blev landsat fra både vest for Matanikau nær landsbyen Kokumbuna den 27. august med henblik på at angribe japanske enheder i området, stort set ligesom i de første kampe ved Matanikau den 19. august.
