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.—

TO GENERAL WASHINGTON.

(ORIGINAL.)

Mrs. Ruffin's, August 20th, 1781.

MY DEAR GENERAL—Independent of the answer to your letter of the 15th, I have been very particular in a second letter intrusted to Col. Moriss. But at this moment wish to send you minuted and repeated accounts of every thing that passes in this quarter.

The enemy have evacuated their forts at Troy, Kemp's Landing, Great Bridge, and Portsmouth. Their vessels with troops and baggage went round to York. Some cannon have been left spiked up at Portsmouth; but I have not yet received proper returns.

I have got some intelligences by the way of this servant I have once mentioned. A very sensible fellow was with him, and from him as well as deserters, I hear that they begin fortifying at York. They are even working by a windmill at which place I understand they will make a fort and a battery for the defence of the river. I have no doubt but that something will be done on the land side. The works at Gloster are finished; they consist of some redoubts across Gloster creek and a battery of 18 pieces beating the river.

The enemy have 60 sails of vessels into York river, the largest a 50 gun ship and two 36 frigates.—About seven other armed vessels, the remainder are transports, some of them still loaded and a part of them very small vessels. It appears they have in that number merchantmen, some of whom are Dutch prizes. The men of war are very thinly manned. On board the other vessels there are almost no sailors.
