Learnt before Chapter 5 Japan attacked Pearl Harbour in 1941.

  • was devastating attack ended in near total success for Japanese.
  • US intelligence failed to warn US forces + Japanese planes from aircraft carriers achieved almost complete surprise against American forces.
  • Attack lasted around 90 minutes, killed over 2000 American Personnel.
    • US lost 18 ships including 5 battleships

3 days after Pearl Harbour Japanese forces sank most powerful British battleships in Pacific Region, prince of wales, and repulse.

In long run Pearl Harbour did not prove to be as decisive as Japanese thought.

  • US was able to recover quickly within few months + retaliate against Japan
  • Outrage over surprise attack - allowed US President Roosevelt to rally the country
  • US now probably more united + organised than it had ever been to declare war on Japan

Country’s huge resources directed towards war. US shipyards quickly constructed new ships esp. aircraft carriers.

  • also produced large number of superior carrier based aircraft

Also some comfort for US navy as its aircraft carriers were not at pearl harbour during attack

  • Japan also made massive error: failed to hunt down + destroy the carriers which US continued to use throughout 1942.
    • Meant that Japan did not gain control of Pacific as they had hoped.

Japanese made many other errors prevented them from capitalising on their initial successes.
