Late in the afternoon, a "Yorktown" scout aircraft located "Hiryū". "Enterprise" launched a strike of dive bombers (including 10 SBDs from "Yorktown"). Despite "Hiryū" being defended by more than a dozen Zero fighters, the attack by "Enterprise" was successful: four, possibly five bombs hit "Hiryū", leaving her on fire and unable to operate aircraft. ("Hornet"s strike aimed at the escort ships but it did not get any hits.) After hopeless attempts to control the fire, most of the crew remaining on "Hiryū" were taken off the ship. The rest of the fleet continued sailing northeast to catch the American carriers. "Hiryū" stayed afloat for several more hours. She was discovered by an aircraft from the light carrier "Hōshō". This led to hopes she could be saved or towed back to Japan. However, soon after being spotted, "Hiryū" sank. Rear Admiral Yamaguchi chose to go down with his ship, costing Japan her best carrier officer.
