31 December 1781
Monsieur Galvan entered the service of the United States as a Lieutent in the 2d Regt of South Carolina in Septemr 1776. In January 1780 he was promoted to the Rank of Major and served that Camapign in the Light Infantry of the Army under my immediate command—In the beginning of the present year he was appointed to a command in the detachment formed under Major Genl The Marquis de la Fayette for the support of the State of Virginia. For His services upon that occasion he has received very honorable testimonials from the Marquis—His Health having obliged him to quit his command in the line, he acted at the Seige of York as Division Inspector and performed the duty of Major of the Trenches to Major Genl Baron de Steuben.
In the different services upon which I have had occasion to employ Majr Galvan, I have found him Zealous—brave—active and intelligent—and I have every reason to believe that he has upon all other occasions conducted himself equally well. Given under my Hand and Seal at Philada the 31st of Decemr 1781.
