World War II: The “Big Three” Turn the Tide President Franklin D. Roosevelt In 1940, FDR viewed Germany as the greatest threat to U.S. security and the future of democracy By giving material aid to GB, the U.S. would act as “the great arsenal of democracy” Wished to defend the “four freedoms” = freedom of speech, freedom of religion, freedom from want, freedom from fear. Lend-Lease Act (1941) permitted GB to obtain all the U.S. arms it needed on credit The Atlantic Charter (1941) with Churchill affirmed their peace objectives -self-determination for all people, no territorial expansion, and free trade Goal = defeat Germany first with fewest U.S. casualties

The Big Three meet at the Yalta Conference, February 1945

Winston Churchill Prime Minister of Great Britain Believed that German defenses were too strong in northern and western Europe Supported an Allied strategy of first attacking German troops in North Africa Goal = move on the attack Germany from the south through the “soft underbelly” of Europe = Italy Joseph Stalin Leader of the Soviet Union (Union of Soviet Socialist Republics) The Soviets faced a brutal attack from Germany Death rates were extremely high among Russian forces and civilians (outnumbered that all Allied deaths combined) Goal = open up a second front in western Europe -promised a 2nd front early in war, didn’t come until 1944

World War II: The Battlefronts Fighting Germany Coordinating their military strategy, the British and Americans concentrated on two objectives in 1942: 1.Overcome the threat of German submarines in the Atlantic 2.Begin the bombing campaign of German cities Battle of the Atlantic Naval war to control the shipping lanes of the Atlantic German submarine warfare contained through developments in the use of radar, sonar, and the bombing of naval bases

Battle of Stalingrad (August 1942-January 1943) Very bloody fighting between German and Russian forces Russian forces defeated the Germans and forced them to retreat Importance Turning point in the fighting of the war in Europe Proximity to Russian oil fields made this a strategic location for the war effort

D-Day Invasion (June 6, 1944) Allied invasion of Normandy in western France Largest invasion by sea in world history Involved over 200,000 Allied troops, 11,000 aircraft, and 4,000 vessels General Dwight Eisenhower commanded troops from the U.S., G.B., France, and Canada Within six weeks over one million more Allied troops landed in western France Allied offensive moved quickly to push back the German occupying forces August 1944 = Allied troops had liberated Paris September 1944 = Allied troops had crossed the German border for the final push to Berlin

The War in the Pacific Fighting Japan The war in the Pacific was dominated by naval forces battling over a vast area Turning points in halting the Japanese advance: 1.Battle of the Coral Sea (May 1942) U.S. aircraft carriers stopped a Japanese invasion of Australia 2.Battle of Midway (June 1942) U.S. destroyed four aircraft carriers and 300 planes = major turning point

Island Hopping Strategy Campaign to get within striking distance of Japan by seizing strategic islands in the Pacific Bypassed strongly held Japanese islands and isolated them with naval and air power 1.Battle of Leyte Gulf (October 1944) the Japanese navy was nearly destroyed, kamikaze attacks were used 2.Battle of Iwo Jima (Feb-March 1945) bloody battle with 27,000 U.S. casualties = 1/3 of all Marines killed in the Pacific

World War II in the Pacific

Bombing of Tokyo (March 1945) Over 80,000 Japanese killed = mostly civilians 200,000 buildings destroyed 16 square mile section of the city was targeted for destruction The Japanese continued to fight even after this serious loss of life and property Potsdam Conference (July-August 1945) Stalin was the only remaining member of the Big Three = Harry Truman (U.S.), Clement Atlee (G.B.) 1.Issued a declaration to Japan to surrender unconditionally or face “prompt and utter destruction” 2.Pledged to hold war-crime trials of military leaders
