Patty Cannon was, by all accounts, among the most barbarous and amoral women in American history.
In Antebellum Delaware, Patty Cannon led a gang who kidnapped free blacks and sold them into slavery further south.
She would indiscriminately murder any man, woman or child - including her own husband and baby — who stood in her way. An 1841 murder pamphlet sums it up, “And we can truly say, that we have never seen recorded, a greater instance of moral depravity, so perfectly regardless of every feeling, which should inhabit the human breast.”
