Remembering December 7, 1941

"Yesterday, December 7, 1941 — a date which will live in infamy — the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan." President Franklin D. Roosevelt so began his address to Congress the day after the attack.

Later that day Congress declared a state of war between the U.S. and the Imperial Government of Japan. Remember Dec. 7Three days later Congress approved similar declarations of war against Germany and Italy. American had entered World War II.

Read the complete text of Roosevelt's speech from Quoteland.com as you listen to a recording of the original broadcast through RealAudio. Also read  the short text of the Congressional Declaration of War on Japan.

An Armed Forces recruiting poster from 1942 reads "...we here highly resolve that these dead shall not have died in vain... Remember Dec. 7th!" In this week's online lesson you will have the opportunity to study and reflect on the event that brought the United States into the second world war.

The Attack on Pearl Harbor

Attacking ZeroYou know the essentials from listening to President Roosevelt's Congressional address — Japan attacked Pearl Harbor and other strategic targets across the Pacific. But how were they able to launch such a successful a surprise offensive? Why were U.S. forces caught so off-guard? President Roosevelt described the damage to American naval and military forces as "severe," but what exactly was the extent of the damage, and how many lives were lost?

Begin your research of The Attack on Pearl Harbor at this site. Although this narrative gives a minimal account of the attack and its aftermath, it provides a lot of good insight into events leading up to the attack.

Explosion of the USS ArizonaFor more detail of the events of that day, visit The History Place and its December 7, 1941 page. View the five photos with captions, and then study the Sequence of Events. Also go to Pearl Harbor: Remembered for a detailed timeline of the attack. As you study the timeline, refer to this Pearl Harbor Anchorage map detailing the location of ships, aircraft, oil storage, and other targets.

What peacetime conditions at Pearl Harbor left ships and aircraft vulnerable, and why were servicemen unable to defend Pearl Harbor against the attack? How many ships and aircraft on both sides were destroyed or sustained damage? How many servicemen and civilians were killed or wounded?

USS Arizona

USS Arizona sinksNearly half those who lost their lives in the attack on Pearl Harbor were aboard the USS Arizona battleship when an 800-kilogram bomb penetrated the hull and struck munitions in the forward magazine. The explosions were enormous and devastating, and the ship  quickly sank to the harbor floor. The complete destruction of the Arizona came to symbolize the blow to America of the Pearl Harbor bombing. Read the Brief History of the USS Arizona at the University of Arizona Library site. View images of the USS Arizona, including photos taken after the attack, at the Special Collections, Photographs page.

The USS Arizona is now a graveyard and war memorial under the direction of the National Park Service. The 184-foot-long Memorial structure floats freely above the mid-portion of the sunken battleship. Arizona MemorialThe memorial, accessible by boat, includes an assembly room, an observation, and a shrine room with the names of those killed on the USS Arizona engraved on the walls. In the words of its architect, ""...the structure sags in the center but stands strong and vigorous at the ends, symbolizing initial defeat and ultimate victory."

Visit the USS Arizona Memorial extended site, view photos of the memorial, and read the additional information about Pearl Harbor and December 7, 1941.
