Was the Japanese attack on Pearl Harbor a failure? What caused the defeat of Allies fleet in the Battle of Java Sea ? What caused the defeat of Japanese fleet in the Battle of Midway? This book try to find the answer. The battle in Coral Sea was a very specific sea war, because for the first time in history of sea war, a task force of carrier ships confronted with another task force of carrier ships. In the Coral Sea battle, it was quite obvious that the sea state and bad weather gave a lot of influence to the morality and nuance of both sides in war. Under such a chaotic, doubtful condition and each not knowing exactly the results of their attacks, both sides tried to "mutually flee away" to save their remaining power.
