The Baylor Massacre (also known as the Skirmish Near Tappan, the Tappan Massacre or the Raid on Old Tappan) was an attack by British forces against Continental Army troops on September 27, 1778, during the American Revolutionary War. A force of British soldiers under the command of Major-General Charles Grey carried a successful surprise attack against the 3rd Regiment of Continental Light Dragoons under the command of Colonel George Baylor near present-day River Vale, New Jersey. 15 Continental Army soldiers were killed while a further 54 were wounded or captured by the British, who lost one soldier killed.
