The Ambush of Geary, also known as the Amwell Skirmish, was a skirmish of the American Revolutionary War fought on 14 December 1776 in Amwell Township of Hunterdon County, New Jersey. Cornet Francis Geary, the leader of a company of dragoons, was shot in an ambush set up by local militiamen led by Captain John Schenck. After British forces captured New York City in the first part of the New York and New Jersey campaign, they established outposts throughout central New Jersey. Geary, the son of Admiral Sir Francis Geary, was operating from a station at Pennington when he was killed in the ambush. His body was concealed and later buried in a shallow grave, preventing its recovery by British troops. In the 19th century local historical interest led to the confirmation of his grave's location, and the establishment of markers at the site and in England. Making a casualty of Geary was one of a number of militia actions that resulted in a reduced scope of British reconnaissance, contributing to the eventual success of George Washington's crossing of the Delaware River and victory at the Battle of Trenton.
