In an attempt to repeat the success of the earlier Meigs Raid against Sag Harbor, Parsons' force crossed Long Island Sound to attack the Loyalist position.
Alerted by spies to the planned assault, Lieutenant Colonel Richard Hewlett strongly fortified the local Presbyterian church, surrounding it with a stockade and earthworks.
[1] In the spring of 1777 Lieutenant General William Howe launched raiding expeditions against Continental Army and local militia storage depots near the city.
[2][3] This expedition, led by William Tryon, the former royal governor of New York, successfully reached Danbury from a landing point in Westport, Connecticut, on April 26, and destroyed provisions and supplies.
On August 16, Parsons, whose brigade was stationed at Peekskill, New York, received orders from Major General Israel Putnam authorizing an expedition against Loyalist targets on Long Island.
Neither side incurred significant casualties (Colonel Webb reported one man wounded), and the small American cannons failed to make an impression on the fortifications.
[9][10] Concerned that armed British ships in the Sound would hear the battle and come to investigate, Parsons called off the assault and retreated, taking with him a dozen captured horses and some blankets.
