Back in Pearl Harbor from 12 July 1944 to 12 August, Fremont sailed then for rehearsal landings in the Solomons, and on 8 September she sortied for the Palau Islands operation.
She came under enemy air attack on several occasions, and on 24 October, during the decisive Battle for Leyte Gulf, a small caliber shell which exploded on her bridge injured seven men.
On 16 May Fremont returned to Leyte Gulf with troops and sailors, and there received men for transportation to the west coast, where she began an overhaul 26 June 1945.
Two voyages to Pearl Harbor, and two more to Pacific islands and the Philippines to bring servicemen eligible for immediate discharge home kept Fremont at sea between 9 October 1945 and 12 August 1946.
The Lebanon Crisis broke out during her 1958 tour of duty, and she joined in landing Marines at Beirut 17 July to 6 August, returning to reembark troops in September.
