"SIR,
"On the 4th, the enemy evacuated Williamsburgh, where some stores fell into our hands, and retired to this place, under the cannon of their shipping. The next morning we advanced, and a part of our troops took post about nine miles from the British camp. The 6th, I detached an advanced corps under General Wayne, to reconnoitre the enemy's situation. Their light parties being drawn in, the pickets which lay near their encampment, were gallantly attacked by some riflemen, whose skill was employed to great effect.
"Having learnt that Lord Cornwallis had sent off his heavy baggage under an escort, and posted his army in an open field, fortified by the shipping, I returned to the detachment, which I found generally engaged. A piece of cannon had been attempted by the vanguard, and the whole British army advanced to the wood, occupied by General Wayne. His whole corps did not exceed 800, part of which were militia, with three field pieces.—But at sight of the British, the troops ran to the rencontre, notwithstanding the very superior number of the enemy, and a short skirmish ensued, with a warm, close and well directed fire. But, as both the right and left of the enemy greatly out-flanked ours, I sent orders to General Wayne, to retire to about half a mile, where Col. Vose and Barber's light infantry battalions had arrived, by a most rapid movement, and where I directed them to form. In this position, they remained till some hours in the night. The militia under General Lawson also advanced; but during the night, the enemy retired to the south of the river.
"From all accounts, the enemy's loss is great. We had none killed, but many wounded. Wayne's detachment suffered most. Many horses were killed, which rendered it impossible to move the field pieces. But it is enough for the glory of General Wayne, and the officers and men under his command, to have attacked the whole British army, with only a reconnoitering party, and to have obliged them to retreat over the river. I have the honor to be, &c.
