For many years I have felt impelled to write this Life, not only in justice to General Stevens’s memory, but also as an act of duty to the young men of the country, that the example of his noble and patriotic career might not be lost to posterity. An only son, closely associated from boyhood with him, his chief of staff in the Civil War, and always the recipient of his counsel and confidence, the opportunities thus given me to know his sentiments and characteristics, and to witness so many of his actions, plainly augment the duty of making his record more widely known. In these pages, setting aside, as far as possible, the bias of filial respect and affection, I seek to simply narrate the actual facts of his life.

Since beginning this work in 1877, I have been greatly assisted by data furnished by many of General Stevens’s contemporaries, former brother officers, and associates in the public service, many of whom have now passed on. I render my grateful thanks to them for such aid, and for their words of appreciation of General Stevens and encouragement to his biographer, and especially to Generals Zealous B. Tower, Henry J. Hunt, Benjamin Alvord, Edward D. Townsend, Rufus Ingalls, A.A. Humphreys, E.O. C. Ord, Thomas W. Sherman, Joseph E. Johnston, G.T. Beauregard, William H. French, Truman Seymour, Orlando M. Poe, Silas Casey, John G. Barnard, M.C. Meiggs, Joseph Hooker, George W. Cullum, David Morrison, George E. Randolph; Colonels Samuel N. Benjamin, Granville O. Haller, Henry C. Hodges, John Hamilton, H.G. Heffron, Elijah Walker, Moses B. Lakeman; Major Theodore J. Eckerson, Major George T. Clark; Captains William T. Lusk, Robert Armour, C.H. Armstrong; Professors W.H.C. Bartlett, A.E. Church, H.S. Kendrick, H.E. Hilgard, Spencer F. Baird; General Joseph Lane, Senator James W. Nesmith; General Joel Palmer, Nathan W. Hazen, Esq., Alexander S. Abernethy, C.P. Higgins; Judge James G. Swan, Arthur A. Denny; Hon. Elwood Evans, General James Tilton.

Towner, Acting Commissioner; to General H. C. Corbin, Adjutant-General; General John M. Wilson, Chief of Engineers; Hon. John Hay, Secretary of State; Professor Henry L. Pritchett, Superintendent of the Coast Survey; Lieutenant Paul Brodie, formerly adjutant 79th Highlanders, for copying hundreds of pages of documents in the Indian Office; Mr. R.F.
