In one of the first Civil War army field manuals, General Butterfield consolidated into one concise book directives on outpost and sentinel duty, standing orders for marches, camps, and bivouacs, rules for health and welfare of the men, 112 extracts from army regulations that "every soldier must know," and the maxims of war and duties of officers in the field. This 1862 compendium became a standard in the Union Army. Today, it is especially useful to students, writers, historians, reenactors, and those interested in army field regulations during the American Civil War.
