TG 76.4. On 2 March, Thomaston departed Subic Bay to execute Operation Eagle Pull which evacuated Americans and designated Cambodian citizens from the capital city of Phnom Penh. The civilians were to be picked up by helicopters and ferried to the ships offshore. She remained in readiness until the evening of 5 April, when Thomaston was ordered to Phú Quốc island to assist Vietnamese nationals evacuated from Da Nang. She transferred food and medical supplies via her LCUs and LCM-8 assault craft to Vietnamese refugees quartered on Military Sealift Command (MSC) vessels. TG 76.4 executed "Eagle Pull" on 12 April, and Thomaston took part as a plane guard on station to the south. Upon the successful completion of the operation, designated units of the group proceeded to Sattahip, Thailand, to debark civilians airlifted from Cambodia. Meanwhile, Thomaston sailed for the Philippines, arriving at Subic Bay on the morning of 17 April, but her much deserved in-port period was again abbreviated by operational necessity. Underway once more at 23:30 on 18 April, Thomaston sailed for Vietnamese waters to take part in the evacuation of the besieged capital, Saigon. On 29 April, Operation Frequent Wind commenced at 15:00. During the next nine hours Thomaston received 811 Vietnamese, American, and other refugees. During this operation — for which the ship received the Meritorious Unit Commendation — Thomaston received evacuees via helicopter, landing helicopters as large as CH-46's on her flight deck aft. All Vietnamese citizens were to be processed and placed aboard MSC ships. American citizens would be retained on board for transportation to the Philippines. Although limited by space, all individuals were provided with food, clothing, and medical attention. Makeshift shelters, "tents" made from marines' blankets, were set up on board. Returning to Subic Bay on 3 May, Thomaston immediately commenced preparations for her homeward voyage. Civilians embarked during Frequent Wind were debarked at Subic Bay. The ship then headed on for the west coast of the United States, via Buckner Bay, Okinawa; and Pearl Harbor; and arrived at San Diego on 6 June 1975. 1975–1998 Thomaston subsequently operated with the Pacific Fleet in 1976, conducting training and local operations in waters off Okinawa, Japan, Korea, and Hawaii, before returning to San Diego at the close of the year. Following a material inspection by the Navy Board of Inspection and Survey in January 1977, Thomaston commenced preparations for her forthcoming overhaul. On
