In midwinter, not quite a year after their capture, the prisoners were visited by a gleam of hope. John Sheldon, accompanied by young John Wells, of Deerfield, and Captain Livingston, of Albany, came to Montreal with letters from Governor Dudley, proposing an exchange. Sheldon's wife and infant child, his brother-in-law, and his son-in-law had been killed. Four of his children, with his daughter-in-law, Hannah,--the same who had sprained her ankle in leaping from her chamber window,--besides others of his near relatives and connections, were prisoners in Canada; and so also was the mother of young Wells. In the last December, Sheldon and Wells had gone to Boston and begged to be sent as envoys to the French governor. The petition was readily granted, and Livingston, who chanced to be in the town, was engaged to accompany them. After a snow-shoe journey of extreme hardship they reached their destination, and were received with courtesy by Vaudreuil. But difficulties arose. The French, and above all the clergy, were unwilling to part with captives, many of whom they hoped to transform into Canadians by conversion and adoption. Many also were in the hands of the Indians, who demanded payment for them,--which Dudley had always refused, declaring that he would not "set up an Algiers trade" by buying them from their pretended owners; and he wrote to Vaudreuil that for his own part he "would never permit a savage to tell him that any Christian prisoner was at his disposal." Vaudreuil had insisted that his Indians could not be compelled to give up their captives, since they were not subjects of France, but only allies,--which, so far as concerned the mission Indians within the colony, was but a pretext. It is true, however, that the French authorities were in such fear of offending even these that they rarely ventured to cross their interests or their passions. Other difficulties were raised, and though the envoys remained in Canada till late in spring, they accomplished little. At last, probably to get rid of their importunities, five prisoners were given up to them,--Sheldon's daughter-in-law, Hannah; Esther Williams, eldest daughter of the minister; a certain Ebenezer Carter; and two others unknown. With these, Sheldon and his companions set out in May on their return; and soon after they were gone, four young men,--Baker, Nims, Kellogg, and Petty,--desperate at being left in captivity, made their escape from Montreal, and reached Deerfield before the end of June, half dead with hunger. Sheldon and his party were escorted homeward by eight soldiers under Courtemanche, an officer of distinction, whose orders were to "make himself acquainted with the country." He fell ill at Boston, where he was treated with much kindness, and on his recovery was sent home by sea, along with Captain Vetch and Samuel Hill, charged to open a fresh negotiation. With these, at the request of Courtemanche, went young William Dudley, son of the governor.[70]
