vagaries,--the more so that he was at this very time endeavouring to arrange with Howe a general cartel for the exchange of prisoners; and he knew that the attempt to make thirty cents equal to a dollar would, as he said, "destroy the very idea of a cartel." [Portrait: W Heath] While these discussions were going on, Congress, like the wicked king in the fairy tale, anxious to impose conditions unlikely to be fulfilled, demanded that General Burgoyne should make out a descriptive list of all the officers and soldiers in his army, in order that if any of them should thereafter be found serving against the United States they might be punished accordingly. As no such provision was contained in the convention, upon the faith of which Burgoyne had surrendered, he naturally regarded the demand as insulting, and at first refused to comply with it. He afterwards yielded the point, in his eagerness to liberate his soldiers; but meanwhile, in a letter to Gates, he had incautiously let fall the expression, "The publick faith is broke [_sic_];" and this remark, coming to the ears of Congress, was immediately laid hold of as a pretext for repudiating the convention altogether. It was argued that Burgoyne had charged the United States with bad faith, in order to have an excuse for repudiating the convention on his own part; and on the 8th of January, Congress accordingly resolved, "that the embarkation of Lieutenant-General Burgoyne and the troops under his command be suspended till a distinct and explicit ratification of the Convention of Saratoga shall be properly notified by the court of Great Britain to Congress." Now as the British government could not give the required ratification without implicitly recognizing the independence of the United States, no further steps were taken in the matter, the "publick faith" was really broken, and the captured army was never sent home.
