A Major General in the American army during the Revolution; was a Prussian officer who served many years in the armies of Frederick the Great; was one of his aids, and held the rank of Lieutenant General. He arrived in New Hampshire from Marseilles in November, 1777, with strong recommendations to Congress; claimed no rank, and only requested permission to render, as a volunteer, what services he could to the American army. He was soon appointed to the office of Inspector General with the rank of Major General, and established a uniform system of manoeuvres during the continuance of the troops at Valley Forge, and effected a most important change in all ranks of the army; was a volunteer in the action at Monmouth; commanded in the trenches of Yorktown, on the day which concluded the struggle with Great Britain. He died at Steubenville, N.Y., November 28, 1794, aged sixty-one years. An accomplished gentleman and virtuous citizen, of extensive knowledge and sound judgement. [P. 15.]
