From Diary of the American Revolution, Vol I. Compiled by Frank Moore and published in 1859.
Last night, arrived at the camp in Cambridge, Swashan the chief, with four other Indians of the St. Francis tribe, conducted by Mr. Reuben Colburn, who has been honorably recompensed for his trouble. The above Indians came to offer their services in the cause of American liberty, have been kindly received, and are now entered the service. Swashan says he will bring one-half of his tribe, and has engaged four or five other tribes, if they should be wanted. He says the Indians of Canada, in general, and also the French, are greatly in favor of the Americans, and are determined not to act against them. 1
