I have made use of all these sources of information in gathering the facts. A list of some of the printed authorities consulted follows this preface. In addition thereto, I beg to acknowledge written communications from the following American Army officers, all now on the retired list except Colonels Godfrey and Brainard and Captain Livermore:—Lieutenant-General Nelson A. Miles; Major-General Robert P. Hughes; Brigadier-Generals Henry B. Carrington, George A. Forsyth, Louis H. Carpenter, Anson Mills, Charles A. Woodruff and Theo. F. Rodenbough; Colonel Edward E. S. Godfrey, commanding the Ninth Cavalry; Colonel David L. Brainard, Commissary of Subsistence; Lieutenant-Colonel Samuel M. Horton; Captains Henry R. Lemly, Francis M. Gibson, Nathan S. Jarvis, George E. Albee and R. L. Livermore, Tenth Cavalry; and the following civilians: President E. Benjamin Andrews; Doctors T. E. Oertel and D. D. Thompson; Messrs. W. Kent Thomas, Sigmund Schlesinger, Edward Esmonde, Phineas Towne, W. R. E. Collins, Hugh M. Johnson, Herbert Myrick, R. J. Smyth, William E. Morris, Nicholas E. Boyd, Theo. W. Goldin and Arthur Chapman; Mrs. Guy V. Henry and Mrs. James Powell. In addition to these letters I have gathered much information in conversation with officers and others, not only recently but during many years spent in the West, where I was a frequent guest at army posts, in frontier towns, and at some of the Indian reservations. I knew many of the participants in the stirring incidents and heard the fascinating stories from their own lips. The chapters of the Fort Phil Kearney series have been read and corrected as to matters of fact by General Carrington and Colonel Horton; those referring to the defense of Beecher’s Island, by General Forsyth; those describing the relief of Forsyth and the fight on the Beaver, by General Carpenter; those relating to the Little Big Horn campaign, by General Woodruff and Colonel Godfrey, and the account of the affair at Slim Buttes and the death of American Horse, by General Mills. All of these gentlemen gave me interesting details, anecdotes, etc., besides answering all my inquiries. Several of them put their private papers at my disposal. To Colonel Godfrey I am especially indebted for much interesting matter on the Little Big Horn campaign, and to Captain Gibson for the use of his unprinted account of the Battle of the Washita. The Office of the Secretary of War has been most kind in answering questions and furnishing information not otherwise procurable. Mr. W. H. Holmes, Chief of the Bureau of American Ethnology, Smithsonian Institution, has decided all questions as to the proper spelling of Indian names,[1] and has given me the Indian equivalents of the names of prominent chiefs, as Crazy Horse, Sitting Bull, etc.
