Landing operations began early that morning. "Alshain" had difficulty unloading her cargo due to a shortage of boats and congestion on the beach itself. She finally completed the process on 3 August and retired toward Eniwetok. The ship then sailed independently to Pearl Harbor where she embarked more Army troops and loaded their equipment before getting underway on 27 August for amphibious landing rehearsals at Lahaina Roads, Maui. On 15 September, "Alshain" sailed with Task Group (TG) 33.1 for Eniwetok and a planned invasion of Yap. However, the attack on Yap was later cancelled, and Leyte, Philippines, was substituted as an objective. The cargo vessel departed Eniwetok on 26 September, bound for Manus, Admiralty Islands, the forward staging area for the assault on Leyte.
