When did the Japanese attack Pearl Harbor?

Sunday, December 7, 1941 at 7:55 AM.

The surprise attack on Pearl Harbor, Oahu, Hawaii, was aimed at the Pacific Fleet of the United States Navy and its defending Army Air Forces and Marine air forces. The U.S. public saw the attack as a treacherous act and rallied against the Imperial Japan, causing the United States to enter World War II. Since the attack was on Sunday, the US was undermanned.

The attack damaged or destroyed 12 American warships, destroyed 188 aircraft, and killed 2,403 American servicemen and 68 civilians.

By 10 A.M. the last attack wave was on it's way back to the aircraft carriers that they took off from. A surprise attack, that went off smoothly and caught the Americans asleep .

It was not by chance that the attack was timed for early on a Sunday morning. The Japanese had studied the habits of the US navy and knew that many men would be drunk and sleeping it off by that time. Many more would be " in town " and unable to take part in the defence of their ships.

This attack has also been called the Bombing of Pearl Harbor and the Battle of Pearl Harbor but, most commonly, the Attack on Pearl Harbor or simply Pearl Harbor
