Reaching Eniwetok on 25 September for replenishment, "Almaack" took on fuel and supplies there and pushed on for Manus, in the Admiralties, reaching that place—the staging area for the assault on Leyte—on 3 October. Now assigned to the 7th Fleet for the Leyte operation, Almaack remained at Seeadler Harbor, Manus, from 3 to 13 October, provisioning, fueling, and exercising troops. On the latter date, the ship transferred three wave guide officers, 21 men and six LCVPs to various tank landing ships for the operation, receiving in their place six boat officers, 36 men and six LCSs, for transportation to Leyte.
