1945
After disembarking her passengers and discharging her cargo, the ship shifted to Honolulu on 5 January 1945 and immediately began loading cargo for the Army's 752d Anti Aircraft (AA) Battalion. On the 7th, she embarked 235 soldiers attached to the unit, and sailed independently for the Marshall Islands on the 8th. Reaching Eniwetok on the 16th, Birgit tarried there for a week, topping off her fuel bunkers from Chotauk (IX-188) before leaving the lagoon on the 23d for a round-trip voyage to Saipan and back. The attack cargo ship made Saipan on the 27th and returned to Eniwetok on 3 February. At this point, turbine damage forced Birgit to return to Hawaii for repairs. She set sail alone on 5 February, reached Oahu on the 15th, and entered the Pearl Harbor Navy Yard on the 19th.
Following this availability, Birgit trained near Maui, practicing amphibious landings and tactical maneuvers between 24 March and 29 March. The attack cargo ship then returned to her cargo hauling duties, taking on board freight at Honolulu on the 30th and embarking 235 soldiers on 1 April. Sailing that afternoon for the Marshalls and Marianas, Birgit visited Eniwetok from 10 April to 11 April and Saipan from 14 April to 28 April before she discharged her remaining cargo at Guam on the 28th. This task completed, she sailed for Eniwetok and, for almost four months, served the Commander, Marshalls Gilberts Area, making interisland cargo runs to such places as Eniwetok, Kwajalein, Majuro, and Tarawa.
While Birgit performed the prosaic, but vital, cargo-carrying tasks in the rear areas, the Allied war effort came to a victorious conclusion, sped along by two atomic bombs. V-J Day found Birgit at Eniwetok atoll. On 22 August, after taking on fuel from Meredosia (IX-193), the attack cargo ship got underway for the Philippines as part of 5th Fleet's Amphibious Group 8 and arrived at Guiuan Roadstead off Samar on the 29th. She then sailed for Manila on 4 September and reached that port late on the 6th.
Three days later, Birgit sailed for Lingayen Gulf, routed via Subic Bay, and anchored off Aringay Point on 10 September. There, she loaded 785 tons of ammunition, vehicles, gasoline, and rations, completing the evolution early on the 15th. She then embarked 225 men of the Army's 33d Infantry Division. Birgit took part in a landing rehearsal at Aringay Point on the 17th and then sailed for Japan on the 20th.
Birgit navigated the 600 yard swept channel passing through Kii Suido between Shikoku and Honshū and arrived off Wakayama before dawn on 25 September. Reaching her assigned position off the beachhead at 06:23, Birgit lowered her landing craft, getting them all waterborne within 10 minutes. Then, she proceeded to the inner anchorage area, where she anchored at 10:25. An hour later, she started discharging cargo, using her landing craft. Still, lack of lighterage kept the unloading moving slowly for the balance of the day. The supply of boats improved on the 26th and Birgit's cargo operations speeded up correspondingly. By 17:30, she had unloaded her cargo and disembarked her troops.
Birgit's part in the occupation completed, she weighed anchor on the 27th, sailing for Leyte in company with Duplin (AKA-87), Washburn (AKA-108) and Henninger (DE-476). Routed via Subic Bay, Birgit reached Leyte's San Pedro Bay on 5 October, tarrying there briefly before shifting south to Mindanao, anchoring in Davao Gulf on the 8th. There, the attack cargo ship embarked 135 men of the Army's 21st Regimental Combat Team and loaded 795 tons of cargo. Clearing Davao Gulf on 15 October, Birgit headed back to Japan, arriving at Hiro Wan, off Honshū, on late the 21st. She unloaded her cargo and disembarked her troops at Matsuyama early on the 23rd.
At that point in time, Birgit joined the armada of ships assigned to Operation "Magic Carpet" duty, as she lay in Hiro Wan. Sailing for Okinawa on the 30th, she reached Buckner Bay on 1 November and embarked 407 returning servicemen the following afternoon. She weighed anchor for the United States shortly thereafter and arrived at San Francisco on 17 November. After repairs at the Kaiser dockyard at Richmond, California, Birgit sailed for the Philippines on the 25th, making Guiuan Roadstead at Samar on 13 December. Two days later, Birgit sailed for San Francisco once more with 478 homeward bound men and reached her destination on New Year's Day 1946.
