After the Allied ground forces had pushed the fighting front inland out of range of the destroyer's guns, Walke departed European waters on 3 July and arrived at the Boston Navy Yard on the 9th. Following repairs there and refresher training at Casco Bay, Maine, she sailed south and arrived at Norfolk on 26 August.
Four days later, the ship departed Norfolk in the screen of Ticonderoga (CV-14), bound ultimately for the western Pacific. Steaming via the Panama Canal and San Diego, Calif., the destroyer arrived in Pearl Harbor on 25 September. She conducted training exercises there for almost a month before departing the Hawaiian Islands on 23 October in the screen of North Carolina (BB-55). Steaming via Eniwetok and Manus, she arrived in Ulithi on 5 November. There, she became a unit of Task Group (TG) 38.4, of the fast carrier task force, with which she sortied that day for a series of air strikes on targets in the Philippines. The warship returned from that foray to Ulithi on 22 November and lay at anchor there until the 27th when she got underway with Destroyer Squadron (DesRon) 60 for the Philippines. She arrived in San Pedro Bay, Leyte, on the 29th and joined the screen of TG 77.2 operating in Leyte Gulf. She returned to the anchorage at San Pedro Bay on 4 December and remained there until the 6th when she departed with TG 78.3 to support landings from Ormoc Bay on the western coast of Leyte. The troops of the Army's 77th Infantry Division stormed ashore unopposed on the 7th, but the Japanese mounted heavy kamikaze attacks on the supporting ships in an attempt to foil the assault. During those air raids, Walke assisted Mahan (DD-364) when three kamikazes of a nine-plane raid succeeded in crashing into her. After rescuing a number of Mahan's crewmen, Walke sent the stricken destroyer to the bottom with a torpedo and gunfire. The next day, en route back to San Pedro Bay, she helped to splash an attacking enemy aircraft. She safely reached her destination later that day and operated in Leyte Gulf and at San Pedro Bay until the 13th.
That day, she got underway with TG 77.3 to support the assault on Mindoro. She arrived off that island on 15 December as a part of Rear Admiral Berkley's close covering force, made up of one heavy cruiser, two light cruisers, Walke, and six other destroyers. Besides protecting the heavier elements from air and submarine attack, she destroyed by gunfire the grounded Japanese destroyer Wakaba. After completing that mission, she headed back to Leyte Gulf. En route, she drove off by antiaircraft fire several planes which approached her and arrived safely in San Pedro Bay on 18 December 1944.
The destroyer remained there until 2 January 1945 when she got underway for Lingayen Gulf and the invasion of Luzon. American minesweepers moved into the gulf on 6 January, and Walke steamed in with them to provide covering fire and antiaircraft defense. That day, four enemy "Oscars" approached the destroyer from her starboard side forward, low on the water. She opened fire and succeeded in splashing the first two attackers. The third plane pressed home his combination strafing run-suicide attack and, though hit several times, managed to crash into Walke's bridge on the port side and burst into flames. The destroyer lost all communications, radars, gyro repeaters, and electricity throughout the superstructure. She also suffered extensive damage to the bridge itself as well as to her gun and torpedo directors. The 250-pound bomb the plane carried fortunately did not explode but passed completely through the ship in the vicinity of the combat information center.
Two minutes after the first suicider crashed Walke, the last of the four "Oscars" began his death dive. As this attacker came in toward the destroyer's starboard quarter, he was subjected to fire from 5-inch mount number 3 in local control and from the starboard side 40- and 20-millimeter guns. Their concentrated fire saved the ship from a second crash when the plane burst into flames and splashed into the sea close aboard. Soon thereafter, control was shifted aft to secondary conn, and fires were under control within 15 minutes.
Throughout the action, though seriously wounded and horribly burned, the warship's commanding officer, Comdr. George F. Davis, continued to conn his ship and exhorted her crew to heroic efforts to save the ship. Only after he was certain that she would remain afloat and intact, did he consent to relinquish command to the executive officer and allowed himself to be carried below. Comdr. Davis succumbed to his wounds several hours later but, for his gallant action, he was awarded the Medal of Honor, posthumously. He was further honored by having Davis (DD-937) (q.v.) named for him.
Amazingly, Walke continued to operate with TG 77.2 until after the landings on 9 January. The next day, she departed the gulf with Task Unit (TU) 78.4.2 and headed for Leyte. She arrived in San Pedro Bay on the 13th and remained there undergoing patching for two days before getting underway for the Admiralty Islands. She received further temporary repairs at Manus from 18 to 21 January and then resumed her voyage home, via Pearl Harbor. The ship reached the Mare Island Navy Yard on 6 February and began permanent repairs. The last of her extensive battle damage had been corrected by 4 April.
