John R. Alden was James B. Duke Professor Emeritus at Duke University and wrote a number of biographies of important figures in the American Revolution, including Thomas Gage, Charles Lee, and Stephen Sayre.
The author attempts to make a case that Lee was one of the most important Generals in the American Revolution. However, I was left with the impression of a person who felt he was smarter and more competent than he really was. Despite the author not making his case, it was still a great read. Well written and thoroughly interesting.
