The moment in context
Six Japanese carriers left Hitokappu Bay on 26 November 1941 while diplomacy was still under way, and on 7 December their 353 aircraft attacked Pearl Harbor. The raid killed 2,403 Americans and sank or damaged eight battleships, a stunning tactical success. Yet it missed the American carriers, left the fuel stores and repair yards intact, and so much of the base remained usable, which meant the fleet could be rebuilt far faster than Japan had assumed.
From Pearl Harbor and US entry into WW2, chapter 12 of The Road to War, 1931–1941 (1941).
