Colonel Jackson expects to be called in to pay Knox's contribution to a privateer. Suggests that Henry persuade his wife Lucy to sell her phaeton (a horse drawn carriage), noting that Lucy keeps the carriage in case Henry approves her to visit him at military headquarters. Reports that between the phaeton and the chaise, Lucy will need two more horses than she has. Writes, maybe you'll say it is none of my Business, if she wants 10 Horses, your pay as a Brigr will support it... Notes that a prize arrived at Dartmouth (possibly Massachusetts) with sugar, rum, and cotton.

Knox's wife Lucy writes, ... I am resolved nothing shall prevent my coming to you early in September but your positive refusal, in which case, I will try to be as indifferent as I shall then think you are. Reports that Knox's brother William is on his way to join Henry in New Jersey. Worries that Knox will fall into the usual error of absent lovers- that indifference will take place of that refined affection, which you have entertained for me... From a family letter, Lucy learned that Thomas Flucker, her father, enjoys his three hundred a year as Secretary of the province.

Mentions an express from General [Israel] Putnam to General [William] Heath, in which Putnam attested the British sailed from the Hook (possibly Paulus Hook, New Jersey), but did not know where they were bound. General George Washington assumed they are bound for Philadelphia, but a letter from General [Alexander] McDougal to Colonel Sears in Boston states they may be sailing toward Boston. Notes that Sears's behavior, including his intention to flee Boston, has fright'd all the old women in Town. Does not think the British will come to Boston, but instead expects them to sail up the North River (the Hudson), and attempt to lure Washington over the Delaware River.

As in previous letters, expresses his wish that George Washington would write a letter to the State of Massachusetts to encourage assistance (possibly a draft).

Agrees with Knox, that the British in the New York/New Jersey area will form a junction with the Northern [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 always 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.

Asks about the affair of the Frenchman, declaring that if du Coudray is appointed the head of artillery. Declares that du Coudray is appointed in Knox's place, all the Majr Generals must resign.

Colonel Jackson declares, The loss of Ticonderoga is a very severe stroke, we shall expereance [sic] the misfortune of it as long as the War lasts- there is no one circumstance take'n place this War that has affected the minds of the People so much as this- and there is not one that can acct for its being given up in the maner [sic] it was- not one single Gun fired from us...

Discusses the Continental evacuation of Ticonderoga: My God, what a Stroke we have met with in Loss of Ticonderoga- after all the trouble, pains, & expense the Continent has been at in Fortifyg [sic] that Post, to think we should be obliged to give it up without fire'g a gun- is too much... Predicts that because of the loss, there will be nothing but Scalp'g & [Butcher'g] our back settlements... Reports on the capture of The Fox, a British ship. Mentions the capture of British General Richard Prescott, and hopes for the exchange of Prescott for General [Charles] Lee.
