In 1779 British forces sought to disrupt American naval activity in Long Island Sound. General William Tryon was ordered to cripple the seaports of New Haven, Fairfield, and Norwalk. New Haven was raided on July 5, Fairfield was raided on the 7th and in retribution for resistance by the townspeople, completely burned. Residents of Norwalk, certain of what lay ahead, began to make provisions for the defense of their town, mostly by huddling up in the upper hills of the city known as "The Rocks."
