How Japanese Aircraft Carriers did the US sink?

The U.S. won the battle of the Midway only because the code breakers could figure out the Japanese codes.

During the battle, the U.S. sunk four aircraft carriers, the Akagi, the Kaga, the Soryu, and the Hiryu.

The Japanese, however, only sunk the carrier, the U.S.S Yorktown, which was later repaired and sent back into action.
