Of the many obligations I have incurred over the years, none are now more cheerfully acknowledged than to the five men who taught me: Frank O'Malley and Marshall Smelser at Notre Dame, both now deceased, the late David M. Potter, and Don E. Fehrenbacher and Carl N. Degler at Stanford. I would also like to recognize special debts to Mr. and Mrs. Gordon Wright and to Barton J. Bernstein of Stanford University. William W. Freehling of The Johns Hopkins University has been a constant source of encouragement and inspiration over the years. I have profited much from the support and counsel of Eugene D. Genovese of the University of Rochester, Bertram Wyatt-Brown of the University of Florida, and Michael F. Holt of the University of Virginia. At crucial moments I received important aid from Whitman Ridgway of the University of Maryland, Willie Lee Rose of The Johns Hopkins University, Wythe Holt of the University of Alabama Law School, Thomas Belser of Auburn University, John O'Brien of Dalhousie University, Nettie Lee Benson of the University of Texas, John Craig of the University of Chicago, Stanley Engerman of the University of Rochester, Tom Dillard of Little Rock, Arkansas, and Curtis Carroll Davis of Baltimore.
I also wish to express my deep appreciation to the staffs of the following libraries and archives, in particular: National Archives, Washington, D.C. (especially Michael P. Musick of the Military Archives Division); Manuscripts Division, Library of Congress, Washington, D.C. (especially Chuck Cooney, a former employee); Virginia Historical Society, Richmond (especially John M. Jennings, Howson W. Cole, Waverly K. Winfree, Vir ginius C. Hall, Jr., and the late James A. Fleming--and most especially to a loyal friend and counselor, the late William M. E. Rachal); Virginia State Library, Richmond (especially William G. Ray, Paul I. Chestnut, and a dear friend, Gwynne Tayloe); Alderman Library, University of Virginia, Charlottesville; Southern Historical Collection, Wilson Library, University of North Carolina at Chapel Hill (especially Carolyn Wallace and a dear friend and former employee, Ellen Garrison); the William R. Perkins Library, Duke University, Durham, North Carolina (especially Mattie Russell); the D. B. Weldon Library, University of Western Ontario, London, Canada (especially George Robinson, Jerry
