The Battle of Fort Bull was a French attack on the British-held Fort Bull on 27 March 1756. This was early in the French and Indian war. The fort was built to defend a portion of the waterway connecting Albany to Lake Ontario by the Mohawk River.
Led by Lt. Gaspard-Joseph Chaussegros de Léry the Troupes de la marine, Canadien militia and Native American allies snuck up to the defenders of Fort Bull killing them with bayonets. Then, the Lt. asked for surrender but they refused. Finally the Native Americans broke down the gate killing everyone and looted the fort.
Fort Bull was destroyed and marked the beginning of a whole series of French and Indian raids on the New York frontier, which made Bateauxmen afraid of "the Enemy Schulking parties" as Mercer Complained from Fort Oswego
