THE TRAGEDY OF BENEDICT ARNOLD : AN AMERICAN LIFE
by Joyce Lee Malcolm 

Benedict Arnold, before he was considered a traitor, was recognized as a brilliant officer on both sides of the Revolutionary War. He was a hero who inspired hundreds of men who served under him. Courageous, daring, he went into battle with his head held high. Yet, all of his honor would disappear when he joined the British side. Arnold abandoned the country that he loved turning against it, forever. Why? Author Joyce Lee Malcolm does a tremendous job in unraveling facts from previous books written about Arnold that were not exactly true or correct. Her in-depth research makes you see the kind of man he really was.
The Tragedy of Benedict Arnold is a fascinating story extremely well written by Joyce Lee Malcolm, who is a professor at the Antonin Scalia Law School at George Mason University. She is already an accomplished author having written two other books previously.
I never knew anything about Arnold except for hearing over and over again about his traitorous deed. With this book you get a completely different story as both his personal and public life is fastidiously delved into. 
It's definitely an engaging read and will make you think differently about him.
Highly recommended.
