It is impossible to understand the Second World War without understanding Winston Churchill, the bold British Prime Minister who showed himself to be one of the greatest statesmen any nation has ever known. This lengthy biography is a single-volume abridgment of a massive, eight-volume work that took a quarter-century to write. It covers Churchill's entire life, highlighting not only his exploits during the Second World War, but also his early belief in technology and how it would revolutionize warfare in the 20th century. Churchill learned how to fly a plane before the First World War, and was also involved in the development of both the tank and anti-aircraft defense. But he truly showed his unmatched mettle during his country's darkest moments: "His finest hour was the leadership of Britain when it was most isolated, most threatened, and most weak; when his own courage, determination, and belief in democracy became at one with the nation," writes Gilbert. There are several wonderful books available on Churchill, but this is probably the best place to start.
