Ambler's Plantation, opposite Jamestown, 8 July, 1781.
SIR,—On the 4th inst. the enemy evacuated Williamsburg where some stores fell into our hands, and retired to this place under the cannon of their shipping. Next morning we advanced to Bird's tavern, and a part of the army took post at Norrel's mill about nine miles from the British camp.
The 6th I detached an advanced corps under Gen. Wayne with a view of reconnoitering the enemy's situation. Their light parties being drawn in the pickets which lay close to their encampment were gallantly attacked by some riflemen whose skill was employed to great effect.
Having ascertained that Lord Cornwallis had sent off his baggage under a proper escort and posted his army in an opened field fortified by the shipping, I returned to the detachment which I found more generally engaged. A piece of cannon had been attempted by the van guard under Major Galvan whose conduct deserves high applause.—Upon this the whole British army came out and advanced to the thin wood occupied by General Wayne.—His corps chiefly composed of Pennsylvanians and some light infantry did not exceed eight hundred men with three field pieces. But notwithstanding their numbers, at sight of the British the troops ran to the rencontre. A short skirmish ensued with a close, warm, and well directed firing, but as the enemy's right and left of course greatly outflanked ours, I sent General Wayne orders to retire half a mile to where Col. Vose's and Col. Barber's light infantry battalions had arrived by a rapid move, and where I directed them to form. In this position they remained till some hours in the night. The militia under Gen. Lawson had been advanced, and the continentals were at Norrel's mill when the enemy retreated during the night to James Island, which they also evacuated, crossing over to the south side of the river. Their ground at this place and the island were successively occupied by General Muhlenberg. Many valuable horses were left on their retreat.
From every account the enemy's loss has been very great and much pains taken to conceal it. Their light infantry, the brigade of guards and two British regiments formed the first line, the remainder of the army the second; the cavalry were drawn up but did not charge.
By the inclosed return you will see what part of Gen. Wayne's detachment suffered most. The services rendered by the officers make me happy to think that altho' many were wounded we lost none. Most of the field officers had their horses killed, and the same accident to every horse of two field pieces made it impossible to move them, unless men had been sacrificed. But it is enough for the glory of Gen. Wayne and the officers and men he commanded to have attacked the whole British army with a reconnoitering party only, close to their encampment, and by this severe skirmish hastened their retreat over the river.—
Col. Bowyer of the riflemen is a prisoner.—
I have the honor to be, &e,
