James McPherson

McPherson draws on more than 25,000 letters and nearly 250 private diaries from men on both sides. Civil War soldiers were among the most literate soldiers in history, and most of them wrote home frequently, as it was the only way for them to keep in touch with homes that many of them had left for the first time in their lives. Significantly, their letters were also uncensored by military authorities, and are uniquely frank in their criticism and detailed in their reports of marches and battles, relations between officers and men, political debates, and morale.
