Two wealthy teenagers defy their parents by marrying political radicals - the first was Benedict Arnold, the second Henry Knox. Benedict Arnold's wife was the blonde Philadelphia belle, Peggy Shippen, who fell in love with the famous military hero who then governed the city. Henry Knox's wife was the stunning black-eyed brunette Lucy Flucker, whose Loyalist family never spoke to her again. Defiant Brides of the American Revolution captures how passion and marriage changed their lives of both young women - one who assisted Arnold in his betrayal of America, the other, who faithfully followed General Knox through the army camps of the Revolution.
