The Genius of George Washington by Edmund S. Morgan
In this book Edmund S. Morgan pushes past the image to find the man. He argues that Washington's genius lay in his understanding of both military and political power. This understanding of power was unmatched by that of any of his contemporaries and showed itself at the simplest level in the ability to take command. Drawing on Washington's letters to his colleagues (many of which are included in this book), Morgan explores the particular genius of our first president and clearly demonstrates that Washington's mastery of power allowed America to win the Revolutionary War and placed the new country on the way to achieving the international and domestic power that Washington himself had sought for it.
