The process of publishing a book is one that takes time and the expertise of many people besides the author. For permission to reproduce photos from his collection, I am grateful to Bob Adams. For his excellent drawings of soldiers from classical antiquity, I thank Johnny Shumate. At the Johns Hopkins University Press, editor Trevor Lipscombe and art director Martha Sewall have worked their usual magic, while copyeditor Carolyn Moser has turned my turgid text into pristine prose—thank you all.
