less, two are singled out here
for special mention. James C. Evans, former counselor to the Secretary
of Defense for racial affairs, has been an endless source of
information on race relations in the military. If I sometimes
disagreed with his interpretations and assessments, I never doubted
his total dedication to the cause of the black serviceman. I owe a
similar debt to Lt. Comdr. Dennis D. Nelson (USN Ret.) for sharing his
intimate understanding of race relations in the Navy. A resourceful
man with a sure social touch, he must have been one hell of a sailor.

I want to note the special contribution of several historians. Martin
Blumenson was first assigned to this project, and before leaving the
Center of Military History he assembled research material that proved
most helpful. My former colleague John Bernard Corr prepared a study
on the National Guard upon which my account of the guard is based.
In addition, he patiently reviewed many pages of the draft (p. xii)
manuscript. His keen insights and sensitive understanding were
invaluable to me. Professors Jack D. Foner and Marie Carolyn
Klinkhammer provided particularly helpful suggestions in conjunction
with their reviews of the manuscript. Samuel B. Warner, who before his
untimely death was a historian in the Joint Chiefs of Staff as well as
a colleague of Lee Nichols on some of that reporter's civil rights
investigations, also contributed generously of his talents and lent
his support in the early days of my work. Finally, I am grateful for
the advice of my colleague Ronald H. Spector at several key points in
the preparation of this history.

I have received much help from archivists and librarians, especially
the resourceful William H. Cunliffe and Lois Aldridge (now retired) of
the National Archives and Dean C. Allard of the Naval Historical
Center. Although the fruits of their scholarship appear often in my
footnotes, three fellow researchers in the field deserve special
mention: Maj. Alan M. Osur and Lt. Col. Alan L. Gropman of the U.S.
Air Force and Ralph W. Donnelly, former member of the U.S. Marine
Corps Historical Center. I have benefited from our exchange of ideas
and have had the advantage of their reviews of the manuscript.

I am especially grateful for the generous assistance of my editors,
Loretto C. Stevens and Barbara H. Gilbert. They have been both friends
and teachers. In the same vein, I wish to thank John Elsberg for his
editorial cou
