I think we sunk three carriers. Was it Midway where we lost the Lexington?
It was USS Yorktown, CV-5 that was badly damaged by aircraft from the one surviving Japanese Carrier. Later she was torpedoed by a Japanese submarine and sunk. My dad was on the Yorktown during the battle of Midway.
We sunk four carriers (Kaga, Akagi, Hiryu, Soryu), but lost the Yorktown.
We lost the Lexington at Coral Sea, and the Yorktown took heavy damage. Hasty repairs were performed at Pearl and the Yorktown was sent out to Midway.
