This explanation being unsatisfactory to the American commissioners, and General Howe persisting in his refusal to make the required alteration in his powers, the negotiation was broken off, and this fair prospect of terminating the distresses of numerous unfortunate persons passed away, without effecting the good it had promised. Some time after the failure of this negotiation for a general cartel, Sir William Howe proposed that all prisoners actually exchangeable should be sent in to the nearest posts, and returns made of officer for officer of equal rank, and soldier for soldier, as far as numbers would admit; and that if a surplus of officers, should remain, they should be exchanged for an equivalent in privates. [Sidenote: A partial exchange agreed to.] On the representations of General Washington, congress acceded to this proposition, so far as related to the exchange of officer for officer, and soldier for soldier; but rejected the part which admitted an equivalent in privates for a surplus of officers, because the officers captured with Burgoyne were exchangeable within the powers of General Howe. Under this agreement, an exchange took place to a considerable extent; but as the Americans had lost more prisoners than they had taken, unless the army of Burgoyne should be brought into computation, many of their troops were still detained in captivity. NOTES. NOTE--No. I. _See Page 5._ It will not be unacceptable to the reader to peruse this first report of a young gentleman who afterwards performed so distinguished a part in the revolution of his country, it is therefore inserted at large. I was commissioned and appointed by the Hon. Robert Dinwiddie, Esq. Governor &c. of Virginia, to visit and deliver a letter to the commandant of the French forces on the Ohio, and set out on the intended journey on the same day: the next, I arrived at Fredericksburg, and engaged Mr. Jacob Vanbraam to be my French interpreter, and proceeded with him to Alexandria, where we provided necessaries. From thence we went to Winchester, and got baggage, horses, &c. and from thence we pursued the new road to Wills' Creek, where we arrived the 14th November. Here I engaged Mr. Gist to pilot us out, and also hired four others as servitors, Barnaby Currin, and John M'Quire, Indian traders, Henry Steward, and William Jenkins; and in company with those persons left the inhabitants the next day. The excessive rains and vast quantity of snow which had fallen, prevented our reaching Mr. Frazier's, an Indian trader, at the mouth of Turtle creek, on Monongahela river, until Thursday the 22d. We were informed here, that expresses had been sent a few days before to the traders down the river, to acquaint them with the French general's death, and the return of the major part of the French army into winter quarters.
