With Halsey's force out of the way, the Japanese intended to attack the Allied landings on Leyte. The U.S. responded with their few remaining forces, the three escort carrier groups of the Seventh Fleet. Escort carriers and destroyer escorts had been built to protect slow convoys from submarine attack, and were later adapted to attack ground targets, but they had few torpedoes, as they normally relied on Halsey's fleet to protect them from armored warships. These ships, organized as Task Unit 77.4.3 ("Taffy 3"), and commanded by Rear Admiral Clifton Sprague, possessed neither the firepower nor the armor to oppose the 23 ships of the Japanese force, which included "Yamato"s 18-inch guns, but took the initiative and attacked. In addition to ships firing on the Japanese from point-blank range, aircraft including FM-2 Wildcats, F6F Hellcats and TBM Avengers, strafed, bombed, torpedoed, rocketed, and depth-charged the Japanese force until they ran out of ammunition. They then resorted to deception, including numerous "dry runs" at the Japanese ships. Concerned that he faced a larger force than he actually did, Japanese commander Admiral Takeo Kurita decided to withdraw.
