On 25 July (Jig+1), Lieutenant Colonel Hays' 1st Battalion, 8th Marines began the day under control of the 24th Regiment. They received orders to relieve the 1st Battalion, 24th Marines, along the coast on the extreme left flank of the beachhead. This shift was accomplished at 09:20, almost the same moment that Hays' unit reverted to its parent regiment, the newly landed 8th Marines. The latter, now attached to the 4th Division, assumed the northernmost sector of the front with 2 medium and 2 light (flamethrower) tanks from the 2nd Tank Battalion attached. 8th Regiment then began to struggle northward toward Ushi Point.
