In an attempt to lure the US Pacific Fleet’s few remaining aircraft carriers into a trap, the Imperial Japanese Navy launched an offensive against Midway Atoll. Warned of Japanese plans by its code-breakers, the US was prepared for the attack and successfully ambushed the Japanese force, sinking all four of its major aircraft carriers—Akagi, Kaga, Soryu, and Hiryu—and a heavy cruiser for the loss of just the carrier Yorktown and a destroyer.
