Near this site stood Reuben Wright’s Mills, which served as General Washington’s headquarters from July 20th to 25th, 1778, and were also occupied by other Revolutionary generals. The mills stood in Old Kensico Village, now inundated by the waters of Kensico Lake. These millstones were placed by the White Plains Chapter D.A.R. on Oct. 28th, 1932, the 156th anniversary of the Battle of White Plains in 1776.
