Colonel Johnson Harmon (or Harman; c. 1675 – 1751) was an army officer in colonial America. He led the expedition during Father Rale's War that killed Father Sébastien Rale in the Battle of Norridgewock. Harmon was heralded as a hero upon his return to Boston. New England Officer and historian Samuel Penahallow proclaimed the attack was "the greatest victory we have obtained in the three or four last wars."[2]
