WEISSENFELS, Frederick H, Baron de, soldier, b. in Prussia in 1738; d. in New Orleans, La., 14 May, 1806. During his early life he was an officer in the British service, but he emigrated to this country, and in 1763 settled in Dutchess county, N. Y. He became lieutenant-colonel of the 3d New York battalion in 1776, and afterward commanded the 2d New York battalion at White Plains, Trenton, the surrender of Burgoyne, and the battle of Monmouth. He accompanied Gen. John Sullivan's expedition against the Six Nations in 1779, and fought at Newton. The war left him impoverished, and at the time of his death he filled a minor office in New Orleans.
