Infamy: LIFE Presents Rare and Unseen Photos from Pearl Harbor

From LIFE:

President Franklin Roosevelt declared December 7, 1941 — when Japan launched more than 350 fighters, bombers, and torpedo planes against the U.S. naval base in Hawaii — a “date which will live in infamy.” In fact, that Sunday morning 70 years ago is so seared into America’s memory that the tumult of the weeks and months afterward, as the U.S. responded to the attack, is often overlooked. Here, on the 70th anniversary of Pearl Harbor, LIFE.com presents rare and unpublished photos from Hawaii and the mainland, chronicling a nation’s answer to an unprecedented act of war.
