On receiving intelligence of the loss of Stony Point, and of the danger to which the garrison of fort Fayette was exposed, Sir Henry Clinton relinquished his views on Connecticut, and made a forced march to Dobbs’ Ferry. Some troops were immediately embarked to pass up the river, and a light corps was pushed forward to the Croton. This movement relieved fort Fayette.
The failure of the attempt to obtain possession of Verplank’s Point leaving that road of communication still closed, diminished the advantages which had been expected to result from the enterprise so much, that it was deemed unadviseable to maintain Stony Point. On reconnoitring the ground, General Washington believed that the place could not be rendered secure with a garrison of less than fifteen hundred men; a number which could not be spared from the army without weakening it too much for farther operations. He determined therefore to evacuate Stony Point, and retire to the Highlands. As soon as this resolution was executed, Sir Henry Clinton repossessed himself of that post, repaired the fortifications, and placed a stronger garrison in it; after which he resumed his former situation at Philipsburg.
The two armies watched each other for some time. At length, Sir Henry Clinton, finding himself unable to attack Washington in the strong position he had taken, or to draw him from it, and being desirous of transferring the theatre of active war to the south, withdrew into York Island, and was understood to be strengthening the fortifications erected for its defence, as preparatory to the large detachments he intended making to reinforce the southern army.
Although this movement was made principally with a view to southern operations, it was in some degree hastened by the opinion, that New York required immediate additional protection during the absence of the fleet, which was about to sail for the relief of Penobscot.

Early in June, Colonel M’Clean, with six hundred and fifty men, had penetrated from Nova Scotia into the eastern parts of Maine, and taken possession of a strong piece of ground on the Penobscot, which he had begun to fortify.
[Sidenote: July 25.]
The state of Massachusetts, alarmed at an invasion which threatened a serious diminution of territory, determined to dislodge him. A respectable fleet, commanded by Commodore Saltonstal, and an army of near four thousand men, under General Lovell, were prepared with so much celerity, that the whole armament appeared in the Penobscot as early as the 25th of July.
M’Clean had taken possession of a peninsula on the eastern side of Penobscot, and had intrenched the isthmus connecting it with the continent. The part towards the river was steep and difficult of access; and was also defended by his frigates and batteries, the principal of which was constructed about the centre of the peninsula.
