War in the Pacific
Japan’s refusal to surrender
World War II in the Pacific• Japan forced soldiers from Korea,
Thailand, Burma & India to fight for their army.
• By 1945, several countries were aiding US efforts in the Pacific: Canada, Australia, China, Philippines, New Zealand and the Netherlands (b/c of Dutch East Indies)
• Between 1942 and 1945, the Pacific War was fought in 4 main areas: China, Central Pacific, SE Asia & SW Pacific

• Led by General Douglas McArthur
Japanese Offensive: 1941-1942• Japan attacks American and British military bases
across the Western Pacific.• Rapid conquests of Hong Kong, Burma, New

• By early-1942, it became difficult for Japanese to maintain control of vast empire.
• Low on resources and weapons• Codebreakers discovered several planned attacks• Once a 2nd front in Europe is opened (1942), American forces
concentrated on island hopping: a military strategy of attacking specific enemy-held islands.
• Battle of the Coral Sea: (5/4/1942) mutual bombing of navies• Battle of Midway: (6/4/1942) U.S. wins its first Pacific battle by
fighting entirely from the air and destroying the Japanese navy.

Hiroshima and Nagasaki
Civilian Warning Pre-Hiroshima• TO THE JAPANESE PEOPLE:
America asks that you take immediate heed of what we say on this leaflet.
• We are in possession of the most destructive explosive ever devised by man. A single one of our newly developed atomic bombs is actually the equivalent in explosive power to what 2000 of our giant B-29s can carry on a single mission. This awful fact is one for you to ponder and we solemnly assure you it is grimly accurate.
• We urge that you accept these consequences and begin the work of building a new, better and peace-loving Japan.
• You should take steps now to cease military resistance. Otherwise, we shall resolutely employ this bomb and all our other superior weapons to promptly and forcefully end the war.
Civilian Warning Pre-Nagasaki• ATTENTION JAPANESE PEOPLE. EVACUATE YOUR CITIES.
Because your military leaders have rejected the surrender declaration, two momentous events have occurred in the last few days.
• The Soviet Union, because of this rejection on the part of the military has notified your Ambassador Sato that it has declared war on your nation. Thus, all powerful countries of the world are now at war with you.
• Also, because of your leaders' refusal to accept the surrender declaration that would enable Japan to honorably end this useless war, we have employed our atomic bomb.
• A single one of our newly developed atomic bombs is actually the equivalent in explosive power to what 2000 of our giant B-29s could have carried on a single mission. Radio Tokyo has told you that with the first use of this weapon of total destruction, Hiroshima was virtually destroyed.
• Before we use this bomb again and again to destroy every resource of the military by which they are prolonging this useless war, petition the emperor now to end the war. Our president has outlined for you the thirteen consequences of an honorable surrender. We urge that you accept these consequences and begin the work of building a new, better, and peace-loving Japan.
• Act at once or we shall resolutely employ this bomb and all our other superior weapons to promptly and forcefully end the war.
• EVACUATE YOUR CITIES.
