I had heard this story but forgotten the man’s name. Knitebane Manor posted a reminder a few days ago, so a tip of the hat for the reminder.
Samuel Whittemore, who at the age of 80, took a musket and two pistols and attacked the 47th Regiment of Foot as they retreated from Lexington and Concord on April 19th, 1775. He killed three. The British Regulars shot him in the face and then bayoneted him 13 times. When the British moved on, the colonists found him grimly trying to reload. He survived this battle and lived to see the founding of the United States.
He is the official state hero of Massachusetts.
