To His Excellency Genl. Washington, Commander in Chief of the armies of the United States of America. : this plan of the investment of York and Gloucester has been surveyed and laid down, and is most humbly dedicated by His Excellency's obedient servant,

General Washington asked Major Sebastian Bauman, an American artillery officer and military engineer, to survey the terrain and battle positions at Yorktown, three days after the British surrendered there. It was the first large-scale battle map printed in the United States, sold by subscription only with relatively few sheets printed. New-York Historical holds two copies, one of which is believed to be Bauman's personal copy. Shows British and American troop positions, British defenses, including those on Gloucester Point, fields of fire, the first and second parallels, the headquarters of generals Washington and Rochambeau, the quarters of generals Nelson, Lincoln, Lafayette, Knox, Steuben, Clinton, and various French officers, ships in the York River, and "The Field where the British laid down their Arms." Also shows "Moore's House," vegetation and relief. Includes "References to the British Lines" with illustrations of ships and "Explanation" of the American and French siege operations. --cf. LC Maps of North America, 1750-1789. "This plan was taken between the 22nd & 28th of October, 1781."-- cartouche at foot. "Note. The Land within the doted [sic] lines has been laid down by survey." Relief shown by hachures. New-York Historical copy from the collection of Chancellor Robert Livingston; gift of Goodhue Livingston Sr., November 1950.
