For the next four days, "Benham" screened troop transports at sea while other warships conducted gunfire missions against enemy forces on Tinian. After the landings on 24 July, the destroyer spent the rest of the month firing at targets around Sunharon town during the day and covering Marine Corps battalions with defensive gunfire at night. "Benham" also closed the island in the evenings to fire interdiction missions and pound enemy gun emplacements. On 6 August, the destroyer shifted to Guam and spent four days bombarding the last Japanese positions on the northeast corner of the island. With the island declared secure on 10 August, "Benham" steamed east to Eniwetok for repairs alongside a tender.
