[327] The information upon which the entire incident is built is contained in the letter of Snelling to Atkinson, May 31, 1827, in _Indian Office Files_, 1827, No. 10; the letter of Taliaferro to Clark, May 31, 1827, in Indian Office Files, 1827, No. 12; Neill's _The History of Minnesota_, pp. 391-394; _Reminiscences of Mrs. Ann Adams_ in the _Minnesota Historical Collections_, Vol. VI, pp. 107-110; _A Reminiscence_ _of Ft. Snelling_, by Mrs. Charlotte O. Van Cleve, in the _Minnesota Historical Collections_, Vol. III, pp. 76-81; _Running the Gantlet_ by William J. Snelling (the son of Colonel Snelling) in the _Minnesota Historical Collections_, Vol. I, pp. 439-456. The last mentioned account was originally published as a magazine article, and much of it is undoubtedly the product of the author's imagination. It is from this that the writer drew the story of Toopunkah Zeze. The article by Mrs. Van Cleve is full of errors and there are some mistakes in Mrs. Adams's reminiscences. For the facts of the attack the writer depended upon the two reports in the _Indian Office Files_. In a letter written from Prairie du Chien the next winter Joseph Street says that a hostage, an innocent man, was among the Sioux who were executed.--Street to Dr. Alexander Posey, December 11, 1827, in the _Street Papers_, No. 7. Of those who were shot, says Sibley in his reminiscences, all recovered.--_Minnesota Historical Collections_, Vol. I, p. 475. On the other hand Flat Mouth complained to Schoolcraft in 1832 that four of the number died.--Schoolcraft's _Narrative of an Expedition through the Upper Mississippi to Itasca Lake_, p. 85. [328] _Indian Office Files_, 1829, No. 63. [329] _Minnesota Historical Collections_, Vol. II, p. 135. As here given the mother's speech is partly direct, and partly indirect discourse. The writer has changed it all to the direct discourse. [330] The attack on Hole-in-the-Day's band is narrated in the letter of Plympton to General Jones, August 13, 1838.--_Indian Office Files_, 1838, No. 618. See also _Minnesota Historical Collections_, Vol. II, pp. 134-136; Pond's _Two Volunteer Missionaries among the Dakotas_, pp. 136, 137. [331] The particulars of the encounter in 1839 are given in a letter written by the Right Reverend Mathias Loras in July 1839, and published in _Acta et Dicta: A Collection of historical data regarding the origin and growth of the Catholic Church in the Northwest_, Vol. I, No. 1, pp. 18-21; and Pond's _Two Volunteer Missionaries among the Dakotas_, pp. 139-147.
