Arriving in Lingayen Gulf, Luzon, 9 January 1945 for the initial landings on Luzon, "Dashiell" remained there on patrol and fire support duty until 10 February. She downed at least three suicide planes, sank several Japanese small craft, and destroyed key positions ashore. She arrived at Ulithi 28 February to join the fast carrier task groups of the 5th Fleet for the raids on Japan and Okinawa during March in preparation for the Okinawa invasion. "Dashiell" screened the assault on 1 April, and remained off the island on radar picket duty. Her toughest battle against the kamikaze flights came on 14 April, when 20 planes attacked her station. She splashed four and outmaneuvered the rest, but was damaged by the near miss of a bomb and put into Ulithi 23 April for repairs. Returning to Okinawa 17 May, she joined the 3d Fleet for continued air attacks on Japan into August. At the end of the war she entered Tokyo Bay and remained there until 6 September, when she sailed for Pearl Harbor and Charleston, South Carolina, arriving 21 October. "Dashiell" was placed out of commission in reserve there 30 March 1946.
