This routine was interrupted for the destroyer on 20 January 1944 by an order to proceed to
Bougainville Strait. There,
Anthony encountered several small
Japanese ships and destroyed a
gunboat and several
barges before resuming her escort duties. The ship got underway on 15 February to shepherd a group of
LSTs to the landing sites on
Green Island. Although
Anthony was originally slated to perform gunfire support duties, the American troops encountered such light enemy opposition when they went ashore that she was not required to carry out that assignment. After a brief respite at Purvis Bay, the destroyer sailed on 23 February to take part in a bombardment of the enemy stronghold at
Rabaul,
New Britain Island. Then, during March, she covered the
invasion of Emirau Island before serving as an escort on several supply runs between
Guadalcanal and Emirau. On 24 April,
Anthony was assigned to duty with a
battleship task force. The destroyer screened , , and to Australia. The warships arrived at Sydney; and, on the 29th after a week of liberty in that city,
Anthony weighed anchor on 6 May to return to Purvis Bay. After brief training,
Anthony and a group of ships sailed on 2 June for the invasion of the
Marianas. They arrived in
Kwajalein on 8 June to refuel, then turned westward toward the Marianas. On 14 June, the destroyer fired her guns on
Saipan and, the next day, screened other ships during
landings on Saipan. On 16 June, she bombarded
Guam. The destroyer then detached to join Task Force 58 (TF 58), the
Fast Carrier Task Force. Her duties then included screening the
carriers and rescuing downed aviators. On 8 July,
Anthony began providing harassing fire on Guam, and the bombardment continued for several days. When relieved, the destroyer proceeded to
Eniwetok to refuel and take on provisions. She returned to the action off Guam on 21 July and assumed anti
submarine patrol duty. On 10 August,
Anthony was ordered to proceed to Hawaii. She made an intermediate stop at Eniwetok before arriving at Pearl Harbor on the 20th. There, the ship was briefly dry-docked for repairs and then took part in training exercises off
Maui.
Anthony sailed for
Ulithi on 15 September and arrived safely in that lagoon on 3 October. Shortly thereafter, the destroyer got underway to return to the west coast of the United States. Soon after her reaching San Francisco, Calif. on 25 October,
Anthony entered the
Mare Island Navy Yard for an overhaul. She left the shipyard on 13 December to travel to
San Diego for a week of refresher training. The destroyer departed the west coast on 20 December with a convoy bound for Hawaii and reached Pearl Harbor on 30 December. == 1945 ==
