Account of one of the most critical periods of World War II. In the spring of 1940, Holland, Belgium, and France fell to Hitler's army. The Soviet Union was Germany's ally, and the United States stood on the sidelines. At this time of peril, it was Britain alone that faced the Nazi army. Thanks to Britain's two great assets: its indomitable leader, Winston Churchill, and the courage and resilience of its people--ordinary citizens who accomplished extraordinary things, a nation's darkest hour became its finest. Through months of intense air bombardment, including the "Blitz" of London, and under permanent threat of invasion, the British people exemplified heroism under fire. The peoples of occupied Europe, and those of the United States, came to see that resistance to Hitler was indeed possible.
