Replies to a letter from Henry from 21 June, in which Knox discussed British movement in detail. Agrees with Knox, that the British in the New York/New Jersey area will "form a junction with the Nothern [sic] Army." Worries that General George Washington had misleading information, believing William Howe intended to march to Philadelphia (Howe did not march to Philadelphia; refer to Knox's letter to Jackson from 21 June). Expresses misgivings regarding the loyalty of Native Americans near Fort Ticonderoga: "These devils will let their Friendship be what it may- will allways take up the hatchet on the strongest side." Declares that if Howe captures Philadelphia, Albany, and Ticonderoga, it may help the Continental cause: "it would Brake up all our dam'd money makers, who are making their Fortunes on the ruin of their Country." Complains of the poor pay for soldiers and officers in the Continental Army. Discusses his regiment. Gives details of an Independence Day celebration held the previous Friday. Reports that a maritime prize landed in Marblehead [Massachusetts] with Jamaican Rum.
