Regardless of the Nazi-Soviet pact, Hitler’s grand scheme had always included the conquest of the Soviet Union.
Operation Barbarossa, codename given to the Nazi invasion of the Soviet Union was a strategic move designed to fulfill Hitler’s vision of Lebensraum (living space) strike a blow at his most hated rivals, the communists, and deny British support from the Soviets.
The operation was prompted by racist fervor; Hitler intended to exterminate “undesirables” such as communists, Jews, and people with Asiatic features.
Hitler did not only want to destroy the Soviet Union he wanted to annihilate large portions of the Soviet population.
Operation Barbarossa marked the high point and the beginning of the end of interest warfare. Operation Barbarossa marked the beginning of warfare that involved governments, armies, and partisans.
Scale of Operation Barbarossa was enormous. Armies of 3 million on either side, with air and naval support, spanned the length of the German-Russian border, covering half of Europe.
Hitler expected to win with his blitzkrieg and gave little thought of a first strike failure.
Germany opened gaping holes in the Soviet defense capturing Minsk, Smolensk and Kiev. As the Red Army retreated, they put forth the scorched earth policy, strategy used by the Soviets, burning everything in their wake.
Hitler makes crucial decision by not heading straight to Moscow. Victory was possible but German arrogance left them under prepared for the Soviet winter.
The delay from the division of the south meant the German army that headed to Moscow was greeted by the brutal winter. Without adequate winter clothing and winter equipment, the German army ground to a halt.
Stalin ordered a huge counter attack, led by Zhukov, the Soviets were able to stop the Nazi advance, winning a great physiological victory and handing Germany their first major setback of the war.
The British concluded that France's defeat was imminent and began preparing an evacuation.
The evacuation plan was code named Operation Dynamo.
Boats of all size (both naval and civil) were used.
It was originally estimated that only 45000 troops could be evacuated.
In the end, over 328 000 troops from Belgium, Britain, and France were evacuated.

Soldiers were forced to abandon their equipment.
Factors
The Luftwaffe was hampered by the RAF and fog.
The English Channel was relatively calm at the time; smaller boats could travel it.
The German army was ordered to stop so that its tanks would not get "bogged down in the canals and rivers around Dunkirk."
This allowed the Allies extra time to evacuate
Results
The evacuation lifted British morale and ensured the war did not end.
The massive loss of equipment at Dunkirk resulted in British dependence on American munitions for rearmament.
3. Battle of Britain and The Blitz
Britain
Germany's last remaining enemy in the West
Germany wanted to seek peace with Britain
A month after the battle of Britain, Hitler clung to illusion of Third Reich co-existing with Britain
Invasion of Britain
Code named "Operation Sea Lion"
The key to a successful invasion was the command of the skies
The Luftwaffe was the German air force responsible for the bulk of the German aggression
Untitled
The Messerschmitt 109 was the plane used by the Luftwaffe
The invasion marked the first time that aircraft would be used as the primary instrument to destroy the enemy's will and capacity to resist
The RAF (Royal Air Force) fought the Luftwaffe in defence of Britain and is largely responsible for Britain's success
In the final days of the Battle of France, Churchill wanted to send six squadrons of the RAF to France. Hugh Dowding, the commander-in-chief of fighter command of the RAF disagreed because he realized how crucial the RAF would be for Britains defence. This has been said to be one of the best strategic decisions in history.
The Battle of Britain
The Battle began on July 10, 1940
British had the advantage of having a home base to operate British squadrons from whereas Germany was using recently captured airfields
The first phase of the Battle was known as Kanalkampf, which focused on small towns
Germany outnumbered the RAF to begin with, but the British overcame this
Britain created planes twice as fast as Germany and
The British developed radar which gave them a large advantage which was crucial to the defence of Britain and the outcome of the war.
The Blitz
September1940 - Hitler ordered the bombing of London
Thousands were killed and night time raids became common
The attacks strengthened Britain rather than weakening it and the RAF rebuilt just when they were at their weakest
Hitler postponed operation Sea Lion and turned his attention to the east
When German U-Boat power reached its peak; 118 seaworthy vessels

Though Allied loses were more heavy, U-Boats were hurt much more due to lack of amount
Effectively began the decline of U-Boat presence, nearly avoiding starvation in Britain
U-320 becomes the last U-Boat to be sunk in Battle; just off Norway
Quantity of allied ships won the Battle of the Atlantic
Allied Defense
ASDIC Sonar
Established in WW1 but developed greatly against boats, airplanes and submarines
Would send message for Aircrafts to attack or convoys of boats to encircle
Budget cut by the Great Depression; and therefore not as potentially useful as it could have been
Battle lasted throughout the majority of the War
America Enters the War
Though they aided the Allied cause, they would not attack Germany prior to entering the War.
In December of 1941 after the Japanese attack on Pearl Harbor
Untitled
Its massive navy assisted in breaking the stranglehold Germany had imposed on Britain
Though there were American Senators who felt that the Germans would win the War; they entered siding with Allies
5. Diplomacy and Coalition Warfare
The Tehran Conference
Meeting of Allies: Stalin, Roosevelt, Churchill - November 1943 Agreed on invasion from West in summer of 1944
Untitled
Canada's Role in Italy
Canadians became spearhead for Allies drive towards Rome - opened June 5, 1944
The US enters the war
Why? Germany's invasion of the Soviet Union Japan's attack on Pearl Harbor British was in need of much aid
Britain, the Soviet Union and the US referred to themselves as the United Nations Due to economic resources and military strength of the US, the tide shifted in favor of the Allied forces
United States was committed to Euro First Policy - defeating Nazi Germ & securing democracy
Strategic Disputes
British favored indirect approach, America wanted direct approach with massive invasion through northwestern France At Arcadia Conference in Washington decision for British-American counteroffensive in Mediterranean in 1942
The Critical Juncture
May 1942 Hitler diverted army south to Crimea and oil fields - severing Soviet Union lifeline for forced surrender Soviet Union got stronger with more nationalism and better trained soldiers End of Jan 1943 German Sixth Army forced to surrender
The Raid at Dieppe
Assault launched August 19, 1942 - biggest hit to Canadian military - most shot before off beach Why here? to move German troops from Russia, trail for full invasion, best trained Canadian troops, Canadians training in England eager to see active duty

1942: A Turning Point
Allies successfully counter attacked on 3 fronts: Egypt, North Africa, Russia
The Casablanca Conference
1943 Churchill and Roosevelt met here to map out future of their combined war efforts Achieved joint declaration that Western Allies would only accept unconditional surrender from Axis powers British plan was to fight Germans in North Africa, Sicily, Italian mainland June 1940 Italian invasion of Egypt - Italian defeats in Africa and Balkans brought Germans to Mediterranean
Operation Husky: The Invasion of Sicily
