15 December, she moved in with the close covering group to participate in the preinvasion shore bombardment, and the subsequent landings went forward against negligible opposition. Some enemy aircraft attempted to attack the invasion force, and Allen M. Sumner joined Moale and in splashing an enemy light bomber. On the following day, the destroyer departed Mindoro to return to Leyte where she arrived on 18 December. Between 26 and 29 December, the warship escorted a resupply echelon to Mindoro and back to San Pedro Bay. 1945 On 2 January 1945, the destroyer stood out of San Pedro Bay, bound for the invasion of Luzon at Lingayen Gulf in the screen for the cruisers and battleships of Vice Admiral Jesse B. Oldendorf's Bombardment and Fire Support Group (TG 77.2). Early on 6 January, Allen M. Sumner moved into Lingayen Gulf to support minesweeping operations. Around noon, her unit came under air attack by kamikazes. The first plane retreated in the face of a heavy antiaircraft barrage while the second attacker hovered just out of range as a decoy to mask a run in by a third suicider. The latter plane dove on Allen M. Sumner strafing as he came. He swooped in out of the sun on the destroyer's port bow and crashed into her near the after stack and after torpedo mount. The warship lost 14 men killed and 19 injured. Extensive damage required her to retire from the gulf and join the heavy units of TG 77.2. Nevertheless, Allen M. Sumner remained in action with that unit and supported the Lingayen operation until 14 January. On that day, she began a long and somewhat circuitous voyage back to the United States for repairs. She arrived at Manus in the Admiralties on 18 January and remained there for nine days. She got underway again on 27 January in company with the escort carrier and, after stopping at Majuro en route, arrived in Pearl Harbor on 6 February. She departed Oahu the next day and arrived at Hunters Point, California, on 13 February to begin repairs. Her renewal work was completed on 10 April and, four days later, she began duty training prospective destroyer crews along the west coast. Just over three months later, on 17 July, she was relieved of training duty and departed San Francisco to return to the western Pacific. The destroyer arrived at Oahu on the 23rd
