The attack on Pearl Harbor occurred on December 7, 1941, when the Japanese navy launched a surprise assault, resulting in significant damage to the U.S. Pacific fleet and the loss of 2,403 lives. This event prompted the United States to declare war on Japan, thus entering World War II, alongside allies Britain and France against the Axis powers. The subsequent U.S. involvement in the war continued for four and a half years, culminating in the defeat of the Axis powers.

4. When in History At this point in history, Japan and China had been at war for some time. Germany and the British had also been at war. The U.S. had not joined forces with anyone yet, but this attack sent them into war. They became allies with the British and Chinese, and WWII had begun. Quit

5. Why Japan Attacked The objective of the Japanese was to strike and destroy the heart of the U.S. Navy before they had a chance to defend themselves. The Japanese believed that it would be inevitable that the U.S. would enter the war, so they set out to destroy the Navy before they could attack. Quit

6. Where the Attack took Place Pearl Harbor is a relatively shallow bay within the island chains of Hawaii. The entire U.S. Pacific Naval fleet was stationed here by President Franklin D. Roosevelt in order to intimidate the Japanese. 100 Naval ships were stationed in this area and it was a safe bay for the fleet, so they thought. Quit

7. Where the Attack took Place The U.S. thought Pearl was a safe bay because it was to shallow for submarines and torpedoes to be affective. This was true, but the Japanese developed new technology by placing wooden boards on the torpedoes so they could travel at more shallow depths. The results were devastating for the U.S. fleet. Quit

8. Outcome The U.S. Naval fleet of the Pacific was caught completely by surprise. The devastation included the deaths of 2,403 people, 188 destroyed aircraft, and 8 destroyed or damaged battleships. Even though the Japanese crippled the U.S. Navy by trying to wipe them out, the result was that they only woke the sleeping giant. This attack single handedly pushed the U.S. into WWII. Five days later, the U.S. declared war on Japan and also Nazi Germany, and Italy. Quit

10. American Response As a result of the Japanese Attacks on Pearl Harbor, the U.S. declared war on the Japanese. The Japanese were allied with the Nazi party of Germany and the Fascist party of Italy. As a result, Germany and Italy declared war on the U.S. U.S. forces had already been allied with the British and French forces but had yet to fight. Great Britain and France were already at war against the Nazi’s and Italy so the U.S. joined forces with the British. WWII was now at full strength. Quit

11. Doolittle’s Attack of Tokyo Four months after the attack on Pearl Harbor, Lieutenant Colonel James Doolittle commanded a raid on Tokyo Japan. This was to be the first attack on the Japanese home islands. This was only a small raid, but it was at the heart of the Japanese industrial center.
