On the evening of February 24, a battalion of British troops was formed; consisting of companies from the 17th of Foot, the 44th of Foot and the 57th of Foot, also a company of Hessian Guards, a Loyalist company of Emmerick's chasseurs and dragoons, and the Loyal American Regiment, plus a small detachment of the royal artillery. Commanded by Major-General William Tryon, the British marched from King's Bridge, and proceeded to Horse Neck, in Connecticut, where they arrived on the morning of February 26.

As the battalion entered the town, they were halted by locals and militia tearing up the bridge at Byram. A company of the 5th Connecticut, and more militia, was stationed on Put's Hill near Knapp's Tavern, under the command of General Putnam. The Continentals exchanged fire with the British but soon retired in good order, leaving their three field-pieces (four-pounders) behind them. The British spiked the artillery, and also captured a large quantity of ammunition and stores found nearby.

A detachment of the 17th and 44th of Foot was sent into the village of Greenwich, where they destroyed the local saltworks, more military stores, a fishing schooner, and two small ketches; after which they rejoined the rest of the battalion at Elizabeth's Point. Determining that more Continental and militia troops would arrive the next morning, Tryon ordered the battalion back to King's Bridge.

Gen Putnam was pursued by British dragoons, and was forced to ride down Put's Hill, in order to elude capture. This historic scene is depicted on the seal of the Town of Greenwich, and the name of Putnam is found throughout the State of Connecticut.
