The Attack on Pearl Harbor
Early on the morning of 7th December 1941, a surprise attack by Japan on Oahu, Hawaii, smashed a large part of the US fleet docked in Pearl Harbor just within 2 hours. This is a significant turning point that brought the full might of the USA into the battle and forced the U.S to enter the World War II.
The Imperial Japanese Navy intended to destroy as much of the US Pacific Fleet as possible. The devastating attack killed 2,400 Americans, damaged nearly around 21 ships and destroyed more than 188 U.S. aircraft.
