The naval clash at in the Coral sea was pivotal in the war against Japan. Since the attack on Pearl Harbor nothing had stood in the way of the Japanese typhoon that had swept across the pacific. Fortress Singapore, the Dutch East Indies there was nothing seemingly the Royal Navy or Americans could do to stop them.
At the Coral Sea three Japanese Aircraft Carriers would face two US Carriers, this would be the first time a naval battle would take place without any belligerent ships seeing one another, it was a new war of carrier launched aircraft.
Was it a draw? Both sides withdrew. History shows us it would be a tactical victory for the Japanese and a strategic victory for the Americans. Perhaps more importantly it was the first time the Japanese were stopped.
