Walter Butler (1752 – October 30, 1781) was a British Loyalist officer during the American Revolution. He was born near Johnstown, New York, the son of John Butler, a wealthy Indian agent who worked for Sir William Johnson. Walter Butler studied law, and became a lawyer in Albany, New York.
At the start of the American Revolution, the women of the Butler family were taken captive in Albany while Walter was commissioned as an Ensign in the 8th (The King's) Regiment of Foot, with which he served at the Battle of Oriskany. When his father, John, formed Butler's Rangers, Walter Butler transferred to that company and was commissioned as a Captain.
In late 1777, he was captured by Continental Army troops while trying to recruit Rangers at Shoemaker Tavern in German Flatts, New York. He was sentenced to death for spying by Lt. Col. Marinus Willett, was imprisoned in Albany; but, after a few months, he escaped and returned to Canada.
In 1778, he and Joseph Brant, a Mohawk chief, led a company of Tories and Indians in the raid that culminated in the Cherry Valley Massacre. He has been blamed for the deaths of the many women and children that were killed on that occasion. He fought in the Battle of Johnstown and was killed on October 30, 1781, while retreating back to Canada in a skirmish with rebel troops (2nd Albany County Militia Regiment) and the Tryon County militia under Marinus Willett in the Mohawk Valley.
