On September 22, 1778, Lieutenant-General Sir Henry Clinton issued orders to Major-General Charles Grey, Major-General Lord Cornwallis, and Brigadier-General Edward Mathew to mobilize troops with the goal of provoking Continental Army commander George Washington into a battle. This operation also served as a diversion for a concurrent raid against a Patriot privateering base in southern New Jersey. The attack was made possible after British forces learned that Colonel George Baylor had secured quarters for his unit of the 3rd Regiment of Continental Light Dragoons in the barns of several farms on Over Kill Road in the area near present-day River Vale, New Jersey.
On September 27, 1778, Major-General Charles Grey led British forces in a surprise attack against the Continental Light Dragoons under Colonel George Baylor's command. The British forces achieved tactical surprise, executing a coordinated assault on the dispersed American cavalry unit that had been quartered in farm buildings. The attack resulted in significant casualties and disruptions to the Continental forces, demonstrating the vulnerability of the American troops when caught unprepared and separated from their main defensive positions.
The engagement resulted in 15 Continental Army soldiers killed and 54 wounded or captured by the British forces. The British sustained only one soldier killed in the action. This casualty disparity reflected the success of Grey's surprise attack strategy and the decisive advantage gained by the British in this encounter. The raid demonstrated British operational capability in conducting swift, coordinated attacks against American positions and served as a significant tactical victory during the Revolutionary War campaign season of 1778.
The American Revolutionary War (1775–1783) grew from colonial resistance to British taxation without parliamentary representation — a dispute that radicalized through the Stamp Act (1765), the Townshend Acts (1767), and the Boston Massacre (1770). Fighting began at Lexington and Concord in April 1775; the Continental Congress declared independence on July 4, 1776. The Continental Army under George Washington faced severe shortages of supplies and troops, enduring the brutal winter at Valley Forge (1777–1778) before French alliance and French financing turned the military balance. Major engagements included Bunker Hill (1775), Trenton (1776), Saratoga (1777) — which secured French intervention — and Yorktown (1781), where British General Cornwallis surrendered to Washington. An estimated 25,000 American soldiers died in service, from combat, disease, and captivity. The Treaty of Paris (1783) recognized American independence and ceded British territory east of the Mississippi, though it left unresolved questions about Indigenous land rights and the status of Loyalists.
