That night, Japanese Marines counterattacked and 2/7 took the brunt of the assault and the fighting continued throughout the night. By the time the sun began to rise, the entire Japanese force had been wiped out. On 14 January, 2/7 along with the rest of the regiment assaulted and took the last Japanese stronghold on the island, Hill 660. Two days later, the counter-attack came but the Marines held the hilltop often resorting to hand-to-hand fighting.

However, Chesty Puller's 1st Marines were having the worst time as they were on the left flank and adjacent to where the mountainous area on Peleliu called the Umurbrogal Pocket began – where all the Japanese holed up. On the night of 20 September the 2nd battalion went out to the transfer line, but there were not enough LVT's. Instead, they had to wait and go in the next morning directly in support of Chesty Puller's 1st Marines. The 2nd battalion went right into the middle of the fighting of the 1st marine regiment. When they landed they were met by intense artillery and mortar fire from Japanese positions that had not been touched by the pre-invasion bombardment. On 20 September, the 7th Marines broke out of their beachhead and linked up with the 1st Marines. The battalion fought on the island for another eight weeks before it was secured.

For 30 days, along with the rest of the Division and the Army 77th Infantry Division, battled the Japanese stronghold.
