Can you give me a brief summary of world war 2?

In 1939, World War II began with the German leader, Adolph Hitler's unprovoked attack on Poland. This and many subsequent acts of aggression, along with numerous crimes against humanity paved the way for the Allies to wage war against her. In the next several years, England, the United States, China, Russia, France, and numerous others stood defiantly against Hitler, sending forth young men to fight on the ground, in the air and at sea to remove German forces from an ever growing number of occupied lands. Beginning in the Mediterranean in 1943, and then moving up into the rest of Europe, US servicemen began an air campaign to rid the world of the German threat. But no sooner did they and their English counterparts begin bombing runs over German targets than their enemy shot them down with fighter planes. Thousands of aircrew's fell from the sky in great explosions. And yet despite the flames, some airmen survived. What became of them? Where did they go? The following links to Stalag Luft III history and testimonials will provide you with some answers as well as help players understand the real life experiences endured by World War II Prisoners of War.
