From George Washington to Henry Knox, 17 June 1791 [letter not found]
Letter not found: to Henry Knox, 17 June 1791. GW docketed Knox’s official letter of 17 April as answered on 17 June, and Knox wrote on 21 June to GW: “I have the honor to acknowledge the receipt of your favors, of the 15th and 17th instant.”1
1. Although Henry Knox wrote “ 17th instant” in his letter of 21 June, he was probably referring to GW’s letter of 19 June (which might have been misdated 17 June; the original receiver’s copy has not been found).
