Battle of Midway
Hiryū, the sole surviving Japanese aircraft carrier attacked. Hiryū'''s first attack consisted of 18 dive bombers and six fighter escorts. They followed the retreating American aircraft and attacked the Yorktown, hitting her with three bombs, which blew a hole in the deck, put out her boilers, and destroyed several anti-aircraft guns. Despite the damage, repair teams were able to fix the flight deck and fix several boilers in an hour. Twelve Japanese dive bombers and four escorting fighters were lost in this attack.
