Five Avengers from "Kitkun Bay" meanwhile at 1105 attacked Chikuma. The Japanese heavy cruiser had already fired most of her antiaircraft ammunition against the U.S. planes that attacked her while crossing the Sibuyan Sea—some of her guns expended all of their live rounds and the gun crews resorted to shooting training rounds. Two torpedoes sliced into the cruiser's port side amidships and water poured into her engine room, causing the ship to lose power. Chikuma drifted to a stop and began listing to port. Nowaki swung around at 1110 to render assistance to her stricken cohort Chikuma.
