At 7:55am sixteen U. S. Marine Corps (USMC) SBD Dauntless led by SBD Dauntless 2129 piloted by Major Lofton R. Henderson attacked Hiryu without result and was lost leading the attack.

After Kaga, Sōryū and Akagi were disabled by aerial attacks by 10:25am, Hiryu was the last undamaged carrier in the Japanese force. At 10:50am and 12:45pm she launched two waves of planes against USS Yorktown (CV-5). Her A6M2 Zeros escorting D3A Vals scored three bomb hits damaging the carrier.

Forty minutes later, two B-17s piloted by Lt. Wuertele and Lt. Grundman also located Hiryu and Haruna and made bomb runs on both, claiming hits (but none were scored).
