Winston Churchill, Adolf Hitler, and Joseph Stalin were the key figures leading Britain, Germany, and the Soviet Union respectively during World War 2. Some key events included Germany's aggression across Europe and Stalin's failure to properly prepare Russia's defense. Key works documenting the war included John Hawke's The Cannibal about early German imperialism, John Hersey's A Bell for Adano about an American officer in Sicily, and Ernie Pyle's Brave Men compiling the journalist's firsthand accounts of American soldiers at war.
