211 Pittsburg 28th July 1794 Sir Last night a Boatman arrived from Fort Washington by land from Wheeling, who delivered a Packet from Head Quarters which is now sent forward in charge of Ensign Semple Major Butler being so obliging on my application as to send Mr. Semple in order if Possible to ensure a safe conveyance, & particularly as we have information that the Pittsburg mail was Robed last Saturday* morning near Greensburg, of this you will no doubt have information by Colo Mintges who sett off same day for Phila. This Robery has been particularly unfortunate to me as the mail contained Returns of Stores up to the first Instant together with an abstract & vouchers of my disbursements at this post during the last six mo. as these papers could be of no use to the insurgents I am in hopes they have suffered the post rider to carry them. I have herewith enclosed a Duplicate of my letter of that date, Duplicates of the Returns & Abstracts of Disbursements can also be made out & Transmitted it is is found necessary.
I am Sir you Obt Humbl Servt Isaac Craig Maj Genl H. Knox *July 26th
