"Shōhō" and the rest of the Main Force were spotted by aircraft from "Lexington" at 10:40. At this time, "Shōhō"s combat air patrol (CAP) consisted of two A5Ms and one A6M Zero. The Dauntlesses began their attack at 11:10 as the three Japanese fighters attacked them in their dive. None of the dive bombers hit "Shōhō", which was maneuvering to avoid their bombs; one Dauntless was shot down by the Zero after it had pulled out of its dive and several others were damaged. The carrier launched three more Zeros immediately after this attack to reinforce its CAP. The second wave of Dauntlesses began their attack at 11:18 and they hit "Shōhō" twice with bombs. These penetrated the ship's flight deck and burst inside her hangars, setting the fuelled and armed aircraft there on fire. A minute later, the Devastators began dropping their torpedoes from both sides of the ship. They hit "Shōhō" five times and the damage from the hits knocked out her steering and power and flooded both engine and boiler rooms. "Yorktown"s aircraft trailed those from "Lexington", and the former's Dauntlesses began their attacks at 11:25, hitting "Shōhō" with another eleven 1,000-pound bombs by Japanese accounts and the carrier came to a complete stop. "Yorktown"s Devastators trailed the rest of her aircraft and attacked at 11:29. They claimed ten hits, although Japanese accounts acknowledge only two. As the Devastators were exiting the area, they were attacked by the CAP, but the Wildcats protecting the torpedo bombers shot down two A5Ms and an A6M Zero. Total American losses to all causes were three Dauntlesses. After his attack, Lieutenant Commander Robert E. Dixon, commander of "Lexington"s dive bombers, radioed his famous message to the American carriers: "Scratch one flat top!"
