Wilder said he decided to cover the subject because Arnold is a name most Americans recognize from the American Revolution, he was closely connected with events in Morristown during the winter encampment of 1779-80s, and because of his heroism and the high esteem in which George Washington held him make for a good story--a contradiction in personality. Most people don't know he was court-martialed in Morristown for financial and business improprieties while acting as military governor of Philadelphia. Probably fewer people are aware he was committing treason right under General Washington's nose during the 1779-80 Morris County winter encampment.
