The artillery was posted on a rising ground, three hundred yards from the enemy, in position to enfilade the main line of their works, and sweep the ground in the rear, Gen. Hand was to support the artillery, the left flanking division to threaten the enemy's right, and Gen. Maxwell's brigade to be held in reserve. Gen. Poor's brigade of four regiments, the right flanking division, and the three companies of riflemen, were to make a circuit of about two miles and turn the enemy's left and attack in flank and rear, to be supported by General Clinton's brigade of four regiments following as a second line. One hour was allowed for this movement, at the expiration of which, the artillery was to open, to be followed by a general assault of the two divisions. Poor almost immediately after commencing his march, found himself involved in a thicket of underbrush, almost impenetrable, but after great difficulty reached the foot of the hill on which the enemy was posted, just at the moment the artillery fire commenced. Forming his line of battle with Lieut. Col. Reid's 2d N.H. on the extreme left, next to him Lieut. Col. Dearborn's 2d N.H., then Alden's 6th Mass., and Col. Cilley's 1st N.H. on the extreme right. To the right of the brigade was the right flanking division of two hundred and fifty men under Col. Dubois, the whole preceded by three companies of riflemen under Maj. Parr. General Clinton's brigade formed line of battle with Col. Gansevoort's 3d N.Y. on the left, next Dubois 5th N.Y., then Livingston's 4th N.Y., with Van Courtlandt's 2d N.Y. on the extreme right, following in the rear of the first line. Poor when about half way up the hill encountered the enemy, but not in sufficient force to materially check the advance of the flanking division, or the regiments on his right; on reaching the summit of the hill, these rapidly pushed forward to seize the defile near the river, a short distance above Newtown, which was the only avenue of escape for the enemy. Almost at the commencement of the cannonade, the main force of the enemy adroitly abandoned their works without being discovered, and precipitated themselves on Col. Reid's regiment in greatly superior numbers. They swarmed about him in a semi-circle, and for a few moments made the forest ring with their exultant shouts, but for a few minutes only; for Col. Dearborn having reached the summit of the hill, and missing Col. Reid on his left, on his own responsibility, faced his regiment to the rear and moved to his assistance. At the same moment the two regiments on the left of Clinton's brigade by a left oblique movement, came up from the rear to Reid's support, and the enemy soon found themselves dangerously threatened. The conflict was short, sharp and decisive, and the war whoop soon gave place to the retreat halloo. Poor with the remainder of his brigade, followed by the two regiments on the right of Clinton, had pushed rapidly for the defile. In the meantime Hand had advanced
