During the American Revolution, British Loyalists used Clyde Blockhouse as a depot for supplies brought from Canada. Two Loyalist units believed to have used the blockhouse were Brant’s Volunteers, led by Mohawk war leader Joseph Brant, and Butler’s Rangers, led by Major John Butler. During the French and Indian War, from 1754 to 1763, the Iroquois village named Sodoms existed in Clyde. It is unclear whether it was still there at the time of the Revolution, but during the Sullivan Expedition a scouting force from General Sullivan’s army passed through Clyde, and Sullivan’s men are claimed to have pursued a party of Butler’s Rangers to a point west of Clyde where a minor battle may have been fought along the banks of the Clyde River. In the late summer of 1779, George Washington ordered a campaign against the Iroquois Indians and the British Loyalists in western New York. One-third of the Continental Army was dispatched to the region under Major General John Sullivan, and this massive military effort, known as the Sullivan Expedition, defeated Butler, Brant, and the Iroquois and destroyed over 40 Native American villages.
