The above image shows the sinking of the USS Arizona at Pearl Harbor.
December 7, annually, was formerly known as Pearl Harbor Day from 1942 until 1993. It was observed in the USA as a day to remember all of the lives lost during the airborne attack by the Empire of Japan on the U.S. Pacific fleet anchored at Pearl Harbor in the then-U.S. territory of the Hawaiian Islands (since 1959, the U.S. State of Hawaii). As the event occurred without a formal declaration of war, the effects of the bombardment were catastrophic and the loss of life severe.
