No one who has hitherto pretended to speak or to write of the grand old agricultural County of Westchester, as a County, during the revolutionary era, has done more than to mention, with more or less of precision and particularity, the movements of two adverse Armies over her highways and her cultivated fields, one of them from Kingsbridge to the White Plains, the other from the Sound to the same objective point ; the skirmish which has been dignified with the name of a Battle, which ensued ; the ridiculous military spectacle of the two antagonistic Armies retreating from the White Plains, in opposite directions, and in the presence of each other; the half dozen military raids, sometimes from one of the belligerents and sometimes from the other, by whom the unarmed and entirely defenceless and previously plundered farmers were subsequently harassed and plundered, again and again ; the denouement of a very serious defection and plot, the latter discovered within that County; the union of the allied forces of France and the United States, previous to that celebrated movement to the Southward which resulted in the capture of Lord Corn wallis and his command ; and the escort duty which was performed by a Troop of Westchester-county Cavalry, when General Washington and Governor Clinton and their respective suites entered the City of New York, the closing military movement of the War of the American Revolution. All these have been told, over and over again, with more or less of precision and particularity, and with mechanical uniformity of order and general statements; but all these various writers, from Gordon and Ramsey to the younger Bolton and Ridpath, have successively and uniformly belittled the history of that community of industrious and peaceful and prosperous and conservative farmers, who occupied what was known, geographically, as the County of Westchester, during the ten years which are now under consideration, a history which consisted, in truth, of vastly more than a series of military movements and the providential detection of a military defection and plot ; and it has consequently been left to other hands and to other pens, to do, with greater labor and less satisfaction, what should have been done, many years since, while the material was more abundant and more procurable, and while some, at least, of the actors in that great drama were here, to afford their more intelligent assistance.
