The writer gratefully acknowledges the aid he has received in the preparation of this book. To President Greene and Mr. J. E. Bell of William Jewell College, Missouri, he is under special obligations. Mr. Bell in order to aid the writer spent several days in Linn County, Missouri, verifying and obtaining facts. To Mr. Herbert Putnam of the Library of Congress, Mr. John Cotton Dana of the Newark, New Jersey, Public Library, and to Dr. Arthur E. Bostwick of the St. Louis Public Library he owes a special debt of gratitude for bibliographies and carefully prepared suggestions as to sources of information. From Cashin's "Under Fire with the 10th U. S. Cavalry," Missouri State Historical Review, Reports of the War Department and other publications, selections and citations have been made and from the facts contained in dispatches from France, particularly the very excellent reports in the New York Times and New York Sun, the writer has obtained valuable information. The direct aid of United States Senator Frelinghuysen in obtaining data from the War Department and the suggestion of United States Senator Warren have been most helpful. Replies to questions sent to friends and relatives of the General have assisted in verifying certain facts and figures. Many who personally knew the great commander in his younger days have very kindly given the writer such help as lay within their power. He gladly recognizes his indebtedness, especially to the following persons: Mr. Charles Spurgeon, Brookfield, Mo.; Judge O. F. Libby, Bigger, Mo.; H. C. Lomax, Esq., Laclede, Mo.; S. E. Carothers, Waco, Tex.; Mr. Robert S. Huse, Elizabeth, N. J., whose father was the "splendid old Caleb" of the Highland Military Academy; Hon. E. W. Stephens, Columbia, Mo.; Mrs. Louisa D. Warren, Meadville, Mo., and Mr. Wesley L. Love, Brookfield, Mo. Major James E. Runcie, Librarian of the United States Military Academy, West Point, N. Y., and General P. C. Harris, acting the Adjutant General, have both been exceedingly kind in providing and verifying certain items of information which otherwise it would have been difficult if not impossible to obtain. The writer wishes to thank all these good people who have helped to make even the gathering of data an inspiration. Articles appearing in many current magazines and newspapers have provided interesting items, but the writer has quoted from them only after verification of certain details.
