  2. Axis Troubles • Never had a coordinated strategy • Shared the same enemies • Had different end games • Germany • Hitler Wanted to dominate Europe and eliminate “inferior” peoples. • Italy • Mussolini had dreams of an Italian Empire from the Adriatic to East Africa. • Japan • Tojo wanted control of the Western Pacific and Asia

  3. Benefits of Partnership • Allies shared a more unified goal for the war. • All, Roosevelt Churchill and Stalin, considered Germany the most dangerous enemy • Didn’t think Italy or Japan posed long term threats • Germany had the resources to bomb Britain, Fight the US and British Navies and invade the Soviet Union. • Allies agreed to fight the war with a “Europe First” strategy • Take care of Germany and Italy then worry about Japan.

  4. Turning the Tides in Europe • America Joining the war boosted the Allies almost immediately • Increase in war supplies and industries • Problem came with delivering the goods across the Atlantic. • Hitler’s U-Boats • Used to stop the supplies before they could make the a difference • Hunted in “Wolf packs” • Sunk more then 3,500 merchant ships and killed thousands of sailors

  5. Gaining advantage over U-boats • In 1943 the tides turned. • Convoys began protecting the merchant ships and major aircraft carriers • Plus, RADAR, a new invention helped locate U boats on the surface at night • Long range bombers and depth charges allowed allied forces to sink U boats faster than the Germans could replace them • Captured a u boat in 1944 and captured the German Enigma Machine and code book.

  6. Enigma Machine • Code machine that encoded typed messages and could only be decoded with matching plugs and another machine. • German codes were almost impossible to decode without it. • Capturing an enigma was a huge boost for helping the Americans decode German messages.

  7. Hitler in Russia • Germans invasion of Russia went in 3 different groups • One group to Leningrad, one group towards Moscow, and one group headed towards Stalingrad • Germans made it into Russia but didn’t reach the goal of capturing the Soviet Union • Resistance by Soviets and Brutal Winter caused halted Germans.

  8. Focus on Stalingrad • In 1942 Hitler focused on southern Russia • Looking at the oil fields in the Caucasus mountains • To get access to Oil he set his sights on Stalingrad. • Battle for Stalingrad was slow and brutal • Fought in city streets, moving a block or two at a time • Soviets counter attacked and trapped the Germans • Hitler didn’t allow a retreat • Winter hit hard and the troops starved and surrendered on Jan 31 1943 • Stalingrad stopped the momentum of the Germans and shifted power to the Allies

  9. Allies in Africa • While the battle for Stalingrad was taking place the Allies were fighting the Italians and Germans in the Deserts of North Africa • Stalin was not happy the Americans and the British were in Africa, wanted to start fighting in France • Roosevelt and Churchill wanted more time to prepare an attack on the Germans in France • Africa required less planning and less supplies • US Forces lead by Eisenhower, Germans lead by Erwin Rommel • Rommel got the early victory in Tunisia, but was forced to retreat due to lack of supplies • Eisenhower needed a stronger attack and wanted a better tank commander to lead the push in Africa- appointed George S Patton

  10. Patton • No Nonsense… No Retreat • “you usually know where the front is by the sound of gunfire, and that’s the direction you should proceed. Now suppose you lose a hand on an ear is shot off, or perhaps a piece of your nose, and you think you should walk back to get first aid. If I see you, it will be the last… walk you’ll ever take.” • Patton advanced east and the British came west in Africa and they trapped Rommel's men in Tunisia • Rommel escaped but his army didn’t the 240,000 troops surrendered in may 1943.

  11. New Plans • Now after loosing Russia and Africa, the Germans were on the Defense • Roosevelt and Churchill met in Casablanca, Morocco to plan their next move. • Decided 2 things • Increase bombing in Germany and Invade Italy • Only Accept Unconditional Surrender. • Germany and Italy will not be allowed anything in surrender, leaders should not expect to remain in power.

  12. Invasion of Italy • Plan to start in Southern Italy, Sicily, as can access easily from north Africa. • British and Americans made separate landings in Sicily but joined forces as they moved north. • Commanded by Eisenhower • Axis escaped to mainland Italy, but now the Allies control the western Mediterranean ski, which ultimately sets them to capture Italy and force Italy to Surrender on September 1943 • Mussolini’s rule ends, but Hitler would rescue Mussolini from a mountain fortress and gave him power over a Nazi puppet state

  13. Push North through Italy • The Campaign to push through Italy into the German controlled North was slow • Mountains and rivers crisscross all of Italy • Heavy rains and snow made traversing mountains with tanks impossible • Had to use mules to cross the mountains • Germans Also held the best defensive positions • Battles were back and forth but the Allies we not able to push into Germany from Italy.

  14. Attacks on Germany • Stalin still wanted the Allies to start in France so the Germans would have to fight a 2 front war • Allies still wanted more time to ready the troops for a French invasion. • Did start nonstop bombing runs from England into Germany • Nighttime bombing raids were a daily occurrence in many German Cities • The Goal was Saturation Bombings trying to inflict maximum damage.

  15. Importance of B-24s • By day the American Bombers practiced Strategic Bombing • Hitting key political and industrial centers • Bombers were protected by fighter squadrons • The most famous squadrons were the Tuskegee Airmen • African American squad that ran more than 1,500 missions and didn’t loose a single bomber • Bombings missions were one of the most deadly missions with a 20 percent casualty rate.

  16. War in the Pacific • While the main focus was Europe, the Americans couldn’t just Ignore the pacific • The Japanese were still making strides in the Pacific though the battle of the Coral Sea did move the momentum in US favor • Japan wanted to stop the Americans in the Pacific before they could retaliate for Pearl Harbor • Admiral Yamamoto sought to destroy the American Aircraft carriers in the Pacific

  17. Midway • Yamamoto turned his attention to Midway • An American naval base that was vital to the US defense of Hawaii • If the Americans were to Loose Midway they would need to retreat all the way back to California • Yamamoto’s plan was to capture midway and then the Aleutian islands near Alaska • Yamamoto didn’t plan on the US commander, Chester Nimitz, knew their plans. • US Navy code breakers had interpreted Japanese messages

  18. Battle of Midway • Nimitz sent all available carriers to Midway • All the navy in the pacific was concentrated on Midway • Japan on the other hand were spread all over the pacific • Battle began on June 4 1942 • One of the most important naval battles of WWII • US used torpedo planes to overwhelm the Japanese ships, sinking 4 aircraft carriers with over 250 planes on board. (along with most of the Japans best pilots) • Became the Turning point and ended the advance of the Japanese forces in the pacific. • Never again threatened Hawaii, Japan is now on Defensive

  19. Pacific Offensive • Americans would go on the offensive after Midway with key battles to move them into position to reclaim land lost • Guadalcanal in the Solomon Islands • A dual attack on Japan • Recapture of the Philippines • Move towards Tokyo Bay.
