The initial treatment of wounded soldiers was usually administered at regimental dressing stations that were located close to the battle lines and protected by earthworks or other natural defenses. These stations were typically manned by one Regimental Assistant Surgeon and one or two medical attendants. The wounded would either come to the dressing station or be helped there by comrades. Wounds were treated with rough dressings and whiskey and opium pills would be administered to ease pain. Ideally, each regiment was assigned six ambulances with six drivers and twelve stretcher bearers that would evacuate the wounded to the Division field hospital.
