The task group returned to Saipan on 14 April, disembarked the marines, and unloaded its cargo. "Southampton" remained at Saipan until 4 June, when she was ordered to the South Pacific to pick up cargo for the Marianas. Over the following two and one-half months, she made two such voyages to the South Pacific and back to the Marianas. During the Nouméa to Kwajalein leg of the return voyage of her second run, she received news of the end of hostilities.
