Having received intelligence thro' two intercepted letters, that Genl Howe had detached a part of his force for the purpose ofl Armstrong with the Pennsylvania Militia should fall down by the Manatawny road by Vandaring's Mill, and get upon the Enemy's left and rear. The divisions of Green and Stephens flanked by McDougalls Brigade were to enter by taking a circuit by way of the Lime Kiln road at the Market House, and to attack their right wing, and the Militia of Maryland and Jersey, under Genls Smallwood and Foreman were to march by the old York road and fall upon the rear of their right. Lord Sterling with Nash and Maxwell's Brigade was to form a Corps-de-Reserve. We marched about 7 o'clock the preceding evening, and Genj Sullivan's advance party drawn from Conway's Brigade attacked the Picket at Mount Airy on Mrs. Allen's house about sunrise the next morning which presently gave way, and his Main body consisting of the right wing following soon engaged the Light Infantry and other Troops encamped near the Picket which they forced from their Ground leaving their baggage. They retreated a considerable distance having previously thrown a party in Mr. Chew's house, who were in a situation not to be easily forced, and had it in their power from the windows to give us no small annoyance, and in a great measure to obstruct our advance.
The attack from our left Column under Gen. Green began about ¾ of an hour after that upon our right, and was for some time equally successful, but I cannot enter upon the particulars of what happened in that quarter, as I am not informed of them with sufficient certainty & precision.

The Enemy are nothing better for the event, and our Troops, who are not in the least dispirited by it, have gained what all young Troops gain by being in action.
We have had, however several valuable officers killed and wounded, particularly the latter. Gen. Nash was among the latter, and his life is despaired of. As soon as it is possible to obtain a return of our loss, I will transmit it. In justice to Gen. Sullivan and the whole right wing of the army, whose conduct I had an opportunity of observing as they acted immediately under my eye, I have the pleasure to inform you, that both officers and men behaved with a degree of gallantry that did them the highest honor.
P. S.—As I have observed, I have not received a return of our loss but from what Gen. Green informs me, I fear it is more considerable than I at first apprehended it to be. The Cannon mentioned above is said to have been brought off in a wagon
