"This explanation being unsatisfactory to the American commissioners, and 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 the prisoners on both sides passed away without effecting the good it had promised.
"Some time after the failure of this negotiation for a general cartel, Howe proposed that all prisoners actually exchangeable should be sent into 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.
"On the representations of 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 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."
The British army held possession of Philadelphia during the winter and the following spring; but they were watched and checked during the whole time by the Americans. They were not quite so closely besieged as in Boston, but they were quite as effectually prevented from accomplishing any military purpose. They sent out occasional foraging parties, who were fiercely attacked by Washington's detachments, and almost always purchased their supplies with blood. But Howe never made an attack on Washington's camp. Doctor Franklin, when he heard in Paris that General Howe had taken Philadelphia, corrected his informant very justly. "Say, rather," said the acute philosopher, "that Philadelphia has taken General Howe." The capture of Philadelphia, as we have already taken occasion to remark, was perfectly useless—in fact, worse than useless—to the British arms. It only provided winter quarters to an army which would have been more comfortable and secure in New York; and it held them beleaguered at a remote point when their services were greatly needed to aid Burgoyne and save his army from capture. In point of fact, Philadelphia did take Howe; and Washington kept him out of the way and fully employed until Burgoyne had fallen, and by his fall had paved the way to the French alliance and to the ruin of the British cause in America.
1. Footnote: The cool contempt expressed in Washington's letter to Conway is one of the most curious features of this affair. It reads as follows: "To Brigadier-General Conway: Sir—A letter which I received last night contained the following paragraph: 'In a letter from General Conway to General Gates, he says, "Heaven has determined to save your country, or a weak general and bad counsellors would have ruined it."' "I am, sir, your humble servant."

3. Footnote: John Hancock, who succeeded Peyton Randolph as president of Congress, retired on the 29th of October, 1777. His successor was Henry Laurens, of South Carolina.
4. Footnote: The correspondence relating to the Conway Cabal is given entire in the Appendix to the fifth volume of Sparks' "Writings of Washington." It is very curious and interesting. Among other letters are anonymous ones addressed to Patrick Henry, Governor of Virginia, and to Mr. Laurens, President of Congress, full of slanders against Washington.
5. Footnote: Previous to this affair, Captain Lee, in his frequent skirmishes with the enemy, had already captured at least a hundred of their men.
6. Footnote: General Conway, after his resignation, frequently indulged in expressions of extreme hostility to the Commander-in-Chief. These indiscretions were offensive to the gentlemen of the army. In consequence of them, he was engaged in an altercation with General Caldwalader, which produced a duel, in which Conway received a wound supposed for some time to be mortal. While his recovery was despaired of, he addressed the following letter to General Washington:
