Pearl Harbor (World War II)

Template:TOC-right On December 7, 1941, units of the Imperial Japanese Navy conducted air and submarine operations against American forces in the Battle of Pearl Harbor. This battle was a key element in the major Japanese escalation of what they call the Pacific War.

While the United States had intelligence suggesting a high probability of Japanese attacks in December 1941, and some specific information that either did not reach the Pearl Harbor commanders, Admiral Husband E. Kimmel (Navy) or Lieutenant General Walter Short (Army), the attack was a tactical surprise.

Few battles, and the circumstances leading to them, have been studied as extensively as this one. Many concepts of the discipline of intelligence and warning resulted from this action.
