Battles of the Pacific Theatre

Japanese Bomb Pearl Harbor

December 7th, 1941 Japan surprised American fleet in Hawaii

Island Hopping: Allied troops moved past Japanese strongholds seizing islands that were not well defended and moved Allied troops closer to Japan

Kamikaze:Japanese suicide pilots crashed bomb-filled aircraft into Allied ships

January of 1942: Japanese attacked the Philippines

Americans fought them from Bataan Peninsula

3 months of fighting before Japan overtook American forces

Japanese considered it dishonorable to surrender and had contempt for prisoners of war

Bataan Death March- 50 mile forced march of POWs

70,000 POWs only 54,000 survived

“I was questioned by a Japanese officer, who found out that I had been in the Philippine Scout Battalion. The [Japanese] hated the Scouts… Anyway, they took me outside and I was forced to watch as they buried six of my Scouts alive. They made the men dig their own graves, and then had them kneel down in a pit. The guards hit them over the head with shovels to stun them and piled earth on top.”

- Lieutenant John Spainhower

Allies from resupplying troops Four days of battle Entire Japanese fleet was destroyed

protect the empire A bloody land battle 100,000 Japanese
