Lieut. Gen. Burgoyne
New York, July 17th. 1777. Dear Sir, I have received yours of the 2.d ins.+ on the 15th, have since heard from the Rebel Army of your being in possession of Ticonderoga, which is a great Event carried without loss. I have rec.d your two letters viz.+ from &Quebec your last of the 14th May, & shall observe the contents. There is a report of a messenger of yours to me having been taken, & the letter discover.d in a double wooden canteen, you will know if it was of any consequence; nothing of it has transpired to us. I will observe you in writing to you, as you propose in your letters to me. Washington is waiting our motions here, & has detached Sullivan with about 2500 men, as I learn, to Albany.- My intention is for Pensilvania where I expect to meet Washington, but if he goes to the Northw.d contrary to my (...) and you can keep him at bay, be assured I shall soon be after him to relieve you. After your arrival at Albany, yr movements of the Enemy will guide yours; but my wishes are that the Enemy be drove out of this Province before any operation takes place in Conecticut. S.r Hen.y Clinton remains in the command here, & will act as occurrences may direct. Putnam is in the Highlands with about 4000 men.- Success be ever with you. Yours.
