First (1862) standard manual for duties in the field Standing orders for layout of camps and marches and duties of officers, provost marshals, surgeons, etc 112 regulations "every soldier must know" Perplexed at the lack of standardization in the units under his command, Brig. Gen. Butterfield sought and gained acceptance from the commanding general of the Army of the Potomac for standardizing the procedures used by Civil War soldiers for performing duty when in the field, such as the laying out of camps, conduct of marches, and the performance of outpost (guard) duty, handling of stragglers, movement of baggage, and related items. The book was for soldiers and officers, and it should be of great interest to historians and reenactors wishing to know how the Army operated when in the field in hostile territory.
