North Castle Septr 17th 1780
By two Deserters from Col. Robinson’s Regiment I am informed that Admiral Rodney has arrived at the Hook and that General Clinton has given Orders to the Flying Army to repair from Long Island to New York Where about seventy Transports are Ordered to be in readiness to receive them and Sail at a Moments warning. I should be happy to know whether it is agreeable to you to exchange Delanceys Cow Boys that may fall into my hands for such Men as they may take—belonging to this Detachment. I am just now inform’d by a Gentleman who has been at West Chester with a flag that he heard one of Delanceys Officers telling another that Admiral Rodney had arrived at the Hook with eight Sail of the Line that he arrived at eight OClock in the morning (what day he did not hear) and Sailed at one OClock the same day. With sentiments of esteem, I am Your Excellencys most Obedient & very humble Servant
