Received Knox's letter via Captain Shaw, and was pleased by Knox's good spirits. Hopes to defeat the British, but worries about the lack of manpower, hearing that Washington only has 4,000 men. If this is the case you must expect a whipping very soon. Hears that there are only 1,200 men and no field officers at Fort Ticonderoga, that Indian skirmishes there have cost many American lives, and that Colonel Baldwin the Engineer was taken prisoner. Unless action is taken he fears this most important post on the Continent may be lost. Colonel Crane lost his struggle to be permitted to use the town bounty in recruiting men. Without the bounty he will lose fine men he could otherwise recruit. Nothing has been done about raising their three battalions, and the legislature says nothing will be done until fifteen other battalions are raised first. Thinks this point will never come, and wishes Washington would order these battalions raised quickly. Worries his young officers will leave if the situation remains stagnant. Has a number of boys learning the drum and fife, but nothing for them to do.

Colonel Jackson asks, What think you of the loss of Ticonderoga, it is in general believ'd here, that that Fortress was sold to the enemy- as for my part, I shall suspend my Judgement till I can hear more of the particulars. Discusses recent news from France that all France is Arm'g their Fleet and Army... to assist America. Also notes that a private letter from Dr. [Benjamin] Franklin to a gentleman in America suggests that a War was inevertable, (possibly inevitable). Mentions the British recapture of their frigate the Fox, which had been taken by the Americans earlier. Notes that unless the court assists, he will not be able to fill his regiment. 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.

Says he has received orders from the Council of this State to march my Independent Company Immediately to Providence. Rhode Island needs these men for defense until 2,000 militiamen can be raised, and Jackson worries that without him his men would not have gone. Also worries what will happen to his continental regiment while he is away, and hopes the general will not disapprove of his actions.

Repeats news he mentioned in a letter from 8 June. Discusses the capture of several British ships with Hessians on board, and asks if he can enlist some of them for service. Comments on various ships, and mentions receiving money from Henry's brother William for Henry's share in the Newbury, apparently a privateer. Notes that Samuel Bradstreet has been accused of being a Tory, and Doctor Boyle is to be sent out of the country. Declares, if the Court does not do something for us, we shall never raise our Regt. it is not money that will get the men... money is as plenty as dirt- there is nothing but what is better than money- Harry you have not the least Idea of the price of goods... Complains of the exorbitant prices charged for goods, and proposes a system in which the military could purchase goods at a lower rate.

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 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.

Colonel Jackson writes to Brigadier General Knox in Morristown, New Jersey. Chides Knox for not writing to him through the last post. Comments that Boston will choose representatives the same day he writes. Expresses relief that Henry's wife, Lucy, and their child recovered from a recent bout of smallpox. In closing, requests Knox to procure an order for the Cloth & Arms & other necessary's for my Regt- dont forget I shall be ambitious to make as good an appearance in field... Relates that in future letters, he will sign as your friend, due to the danger of correspondence falling into enemy hands.

Lengthy letter written at Camp Middlebrook. Replies to an earlier request from Colonel Jackson to enlist Hessians from a captured British ship: I have not mentioned to the General your request to be permitted to enlist some of [the Hessians], it is so repugnant to the good of the service and your own reputation... Discusses General William Howe's recent movements, and General John Sullivan's Continental force in Princeton, New Jersey. Is confused by the movements of the British. Assumed they intended to march to Philadelphia, but they instead fortified their position at Middlebrook, New Jersey. Notes that Mr. Howe, instead of marching to Philadelphia found himself almost blockaded in an open flat County. If Howe had attempted to march on Philadelphia, Knox asserts he should probably had twenty five thousand or thirty thousand militia upon his back... Describes Howe's retreat, at one a.m. the morning of 19 June. While Howe plundered on his way, he was intermittently followed and attacked by American militia. Predicts Howe to attack on the North River (the Hudson). Reports that General John Burgoyne is active near Fort Ticonderoga, and Genl Howe must make an attempt or push for a junction. Notes that the enemy, by all appearances, is leaving New Jersey.
