This compendium of laws and rules is a testimony to America"s reverence for the rule of law as well as its high regard for ethics and standards of civilized behavior in times of war. The Articles of War were normative rules covering military duty, punishments allowed for violations, ranging from passing information to the enemy to how to deal with sutlers. The Lieber Code was new and profound laws for the conduct of armies in the field, to include humane treatment of prisoners of war and protection of property. It had a profound affect on the evolution of the laws of land warfare to this day. Army Regulations, on the other hand, dealt with the administration and management of the army from personnel assignments to supply and recruiting operations -- a fascinating field manual used by both the Union and Confederate armies. An essential reference for students, historians, writers, reenactors, and those interested in how our Civil War armies operated.
