Preston [Boston] 26 April 1775
Sir
The Admiral having ordered a Boat with Fire Grapnels from the Somerset, Boyne and Glasgow, to be on board your Sloop by half after seven o'Clock this Evening, I have his Commands to acquaint you therewith and to signify his Direction that you do dispose of the said Boats during the Night in the most effectual manner to prevent any Attempts of the Rebels either to destroy the Kings Ships, or to land on Boston side The Admiral hopes there will be the strictest Look out kept, and desires the Boats may at Day light be ordered on board their respective Ships. I am &c.
