"Caperton" cleared Espiritu Santo 15 March 1944 for the air operations covering the invasion of Emirau Island, then sailed for the stunning blows hurled from the air at the Japanese on Palau, Yap, Woleai, and Ulithi late in March. Tireless TF 58 continued the crescendo pace of its attacks, and in April "Caperton" screened air strikes preparatory to the invasion of Hollandia, saw the force's planes hit Truk once more, and blasted at Satawan and Ponape in shore bombardment.
