Soon after becoming Prime Minister, Germany invaded France and Britain was alone in Europe fighting Hitler. Churchill inspired the country to keep fighting despite the bad circumstances. He also helped to forge an alliance of Allied Powers with the Soviet Union and the United States. Even though he did not like Joseph Stalin and the communists of the Soviet Union, he knew the Allies needed their help to fight Germany.
With the Allies help, and Winston's leadership, the British were able to hold off Hitler. After a long and brutal war they were able to defeat Hitler and the Germans.
