After this, the St. Louis was released from their duties of a successful operation. Early on the 8th the St. Louis weighed anchor and steamed for Phuket, Thailand, where her crew was granted their first liberty in weeks. The St. Louis arrived in Phuket, Thailand on 11 June and would depart on 15 June. As the St. Louis left Phuket her tasking again was changed. On orders from the Seventh Fleet, the St. Louis was to make the best possible speed to Subic Bay in the Philippines. There the St. Louis would provide humanitarian assistance to the naval base and nearby Cubi Point Naval Air Station during Operation Fiery Vigil after the volcanic eruption of Mount Pinatubo, followed by several days of torrential rains and severe earthquakes.
