4. Battle of the Coral Sea
The Battle of the Coral Sea was the first combat that brought together the American and the Japanese aircraft carriers during World War II. It was exclusively an aircraft fight as none of the ships involved in the battle shot at the enemy ship. While this was the case, several enemy carriers were spotted by the Japanese aircraft, and on May 8, the Allied Forces fleet (U.S. and Australian) were forced to withdraw.
However, the Japenese were more vigilant and expected more U.S. carriers in the area. Considering their options, they decided to cancel Operation MO, which was their objective of capturing both Port Moresby (New Guinea) and Tulagi (the Solomon Islands). By the end of the war, the combined U.S. and Australian forces emerged victorious.
