General Events on 7 December


Attack on Pearl Harbor The Imperial Japanese Navy launched a well-planned surprise attack on the US Navy home base at Pearl Harbor, Hawaii. The US Navy lost many capital warships, but the aircraft carriers were not in port and thus escaped. The attack was a major victory for the IJN. This was, of course, the beginning of the war between United States and Japan. Ironically the USN had themselves "attacked" Pearl Harbor in a wargame scenario a few years earlier, showing the feasibility of such an attack.
