The Second World War pitted two World leaders against each other in 1939: Sir Winston Churchill and Adolph Hilter. Hitler was intending to conquer Europe and the entire world using alliances with Japan, Russia and Italy.
When the war began in 1939, the USA was neutral and Russia was on the same side as Germany. Howver in mid 1941 Germany attacked Russia in Operation Barabrossa.
In December 1941 Japan attacked the USA in the attack at Pearl Harbor Hawaii. This brought the USA into the War. As a result, by the end of 1941 the Axis forces were:
The Allied Forces were:
War was declared by Britain against Germany at 11:00 am on September 3, 1939. Four hours later a Canadian Airman Ellard Alexander Cummings was Killed in a Flying Accident in Scotland. The very next day Albert Stanley Price was Killed in Action during a bombing raid in Germany.
At 4.45 am on 1 September 1939 the German battleship Schleswig-Holstein opened fire on the Polish garrison of the Westerplatte Fort, Danzig (modern-day Gdansk), in what was to become the first military engagement of World War Two. Simultaneously, 62 German divisions supported by 1,300 aircraft commenced the invasion of Poland.
The decision of Adolf Hitler to invade Poland was a gamble. The Wehrmacht (the German Army) was not yet at full strength and the German economy was still locked into peacetime production. As such, the invasion alarmed Hitler's generals and raised opposition to his command - and leaks of his war plans to Britain and France.
Hitler's generals urged caution and asked for more time to complete the defences of the 'West Wall', in order to stem any British and French counter-offensive in the west while the bulk of the Wehrmacht was engaged in the east. Their leader dismissed their concerns, however, and demanded instead their total loyalty.
Hitler was confident that the invasion of Poland would result in a short, victorious war for two important reasons. First, he was convinced that the deployment of the world's first armoured corps would swiftly defeat the Polish armed forces in a blitzkrieg offensive. Secondly, he judged the British and French prime-ministers, Neville Chamberlain and Edouard Daladier, to be weak, indecisive leaders who would opt for a peace settlement rather than war.
