After battle of Midway

  • US + allies → gradually → drove Japanese back across Pacific from the territories they had taken.
    • used strategy known as island-hopping

US island hopping strategy → led to several key victories → 1942-1945

  • such as in battle to regain Philippines → which continued to weaken Japanese military.

Japans resources → severely overstretched → was not able to defend entire empire.

  • Japanese fought fanatically → for each island → in Pacific + each territory in China and Burma.

Soon → war reached pivotal stage.

  • 1945 → US raids on Japanese soil → such as bombing of Tokyo.

April 1945 → Br. and US forces → took island of Okinawa

  • Allies → had to kill/capture → all 100000 Japanese soldiers → defending the island as none of them would surrender. Allied ships → also badly damaged → by Japanese kamikaze → suicide bombers → crashed their planes deliberately into them.
  • attacks were used as last resort by Japanese. Although Japan was being pushed back → came at great cost for Allies.

May 1945 → US → confident → of winning war eventually.

US troops → would have to beat Japanese → island by island → and then invade Japan itself. Alternative:

  • international team of scientists in US → working on what was known as the Manhattan project → had perfected the worlds first atomic bomb

Truman → had to deliberate whether or not to drop the bomb on Japanese.

  • also thought about whether or not he should warn the Japanese or arrange demonstration in unpopulated area.

  • Decided to use bombs without warning

  • accepted military advice → dropped 2 bombs in quick succession.

  • was to convince Japanese → that US → had large stockpile of weapons, which it did not

6 Aug 1945 → American Bomber → Enola Gay → dropped 5 ton atomic bomb → over Hiroshima. 9 Aug 1945 → second atomic bomb → over Nagasaki

→ both caused appalling damage + horrific casualties.

  • reduce both cities to ruins
  • also left legacy of cancer and other radiation related diseases among survivors
