"Gansevoort" departed San Francisco 13 March 1944 to join the screen of a convoy bound from Hawaii to Majuro Atoll in the Marshall Islands where she arrived 1 April. During several months of blockade and antisubmarine patrol in waters off the bypassed enemy garrisons in the eastern Marshalls, she rescued several Marine aviators. Once she closed to within 500 yards of a beach to shell shore batteries while her whaleboat picked up an aviator. She also helped reduce enemy coastal defenses by assisting in the bombardment of Mille Atoll (26 May and 9 June) and Taroa Atoll (8 August). Detached from this duty 19 August, she replenished in Pearl Harbor, then sailed via New Guinea to Manus, Admiralty Islands, to join forces staging for the liberation of the Philippine Islands.
