Sir:

Mr. [William] Duer informs me, that there are two or three Vessels lying at the Dock of Mr. Beverley Robinson in the Highlands. As it is probable, the Men of War which sailed up the River Yesterday, may have anchored to the northward of those Ships, I think it absolutely necessary that an Attempt should be made to secure those Vessels for future Service. I have, therefore to desire the Favour of you, to procure proper Persons to bring these Vessels down the River, and to anchor them under the Fort where General [Thomas] Mifflin commands.

It is absolutely necessary, that this Matter should be conducted with the utmost Secrecy, and Dispatch, and as I am of Opinion that you possess these Requisites, I have thought proper to apply to you, for your Services in this Matter. I am, etc.
