Remembered as the oldest soldier to see combat during the American Revolutionary War, he was nearly eighty years old when he ambushed British troops during their 1775 march from battlefields in Lexington and Concord to Boston, Massachusetts.
As a member of the Third Massachusetts Regiment, he fought during the 1740s in the conflict known as King George's War.
Though he was shot multiple times by the British, he survived and lived for nearly two decades more, dying several months before what would have been his ninety-seventh birthday.
The son of Hannah Rix and Samuel Whittemore, he was raised in Charlestown, Massachusetts.
Whittemore and Isaac Davis (nearly five decades Whittemore's junior) were both Massachusetts-born Revolutionary War soldiers.
