"Hall" carried out varied duties during the month-long invasion of the Marshalls. On 4 February, she supported the landing of troops on Burnet Island in the Battle of Kwajalein. During the Battle of Eniwetok on 18 February, she covered the landings of Engebi Island and supplied gunfire support, and furnished star shell illumination for landings on 22 to 23 February on Parry Island. After an escort voyage with transports to Pearl Harbor and back between 29 February and 26 March, "Hall" was assigned patrol and lifeguard duties in the Kwajalein area. On 4 April, while searching for a downed Marine flyer near Wotje, she received two 6-inch shells close aboard from an enemy shore battery. Suffering one sailor killed, she returned the fire, continued her search, and finally rescued the airman. "Hall" continued her effective role in the overwhelming amphibious victory until departing Majuro atoll 12 May for Pearl Harbor, where she arrived 18 May.
