In 1776 the British had qualified success in the American Revolutionary War. After being
forced to abandon Boston, they
captured New York City, but were unable to hold
New Jersey when General
George Washington surprised them at
Trenton and
Princeton. The British consolidated their hold on
New York City and
Long Island during the winter months of early 1777, while the
Continental Army established a land blockade around the city in New Jersey, southern
New York, and southwestern
Connecticut. In the spring of 1777 Lieutenant General
William Howe launched raiding expeditions against Continental Army and local militia storage depots near the city. A successful raid against
Peekskill, New York in March prompted him to organize a more ambitious expedition to raid a depot in
Danbury, Connecticut. 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. The Connecticut militia had mobilized, and over the next two days skirmished with the British as they marched back to their ships, most notably on April 27
at Ridgefield. General
Samuel Holden Parsons, leading Connecticut's defenses, decided to organize an act of reprisal.
The raid executed with great success by Colonel
Return Jonathan Meigs against
Sag Harbor on eastern
Long Island prompted Parsons to consider further such actions against other
Loyalist positions on the island. 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. Parsons immediately ordered Colonel
Samuel Blachley Webb to muster
his regiment, numbering about 500 men, and march to
Fairfield, Connecticut. Parsons followed, reaching Fairfield on August 21. Loyalists recruited from
Queens County, New York by Lieutenant Colonel
Richard Hewlett for the 3rd battalion
DeLancey's Brigade had established a fortified position in early August on the central north shore of Long Island at
Setauket, just across
Long Island Sound from Fairfield. Hewlett's force took over the town's
Presbyterian meeting house, which they fortified. When spies informed Hewlett that Parsons was mustering troops at Fairfield, he set his force to improving the defenses, building a
breastwork six feet (about 2 meters) high at a distance of all around the meeting house. Upon these works he mounted four small
swivel guns. ==Battle==
