Beginning at 10:22, the two squadrons of "Enterprise"s air group split up and attacked two targets. By accident, both groups attacked the "Kaga". Lieutenant Commander Richard Halsey Best and two other planes headed north to attack "Akagi". Coming under an attack from almost two full squadrons, "Kaga" was hit by four or five bombs, which caused heavy damage and starting fires that could not be put out. One of the bombs landed near the bridge, killing most of the senior officers.
