New Windsor Jany 25. 1781
I last evening received the letter which you were pleased to write me of the 20th instant requesting my opinion of Col. Hay’s conduct in his former and present station.
I can only answer in general that from the character given me of him while serving in the Northern army—from the information I received of his conduct while acting in this department—and from my own observations upon it—I have always considered Col. Hay as a capable useful diligent active and upright servant of the public. My situation however did not enable me to look into the interior of his transactions in business, of course from my own knowlege I could only judge of the results to the service and on these are founded the opinion I have given. I have the honor to be Gentlemen Your Most Obed. & Most humble servant
