Known as Mosier's Fight, a Revolutionary War skirmish took place on December 2, 1781, in the area of present-day Rye Brook: a small force of Westchester County militia commanded by Lieutenant William Mosier successfully repulsed an attack by a much larger British-aligned Loyalist unit of De Lancey's Cowboys. The fight was part of the ongoing, brutal guerrilla warfare between Loyalist and Patriot militias in the Neutral Ground of Westchester County.
