Divisional Medical Service in the American Expeditionary Forces (AEF)

The medical services of the AEF's combat divisions played the centralrole during combat operations in France.  The medical structure ofthe American divisions during the war was markedly different from whatwent before and would come after.  The large American square divisionof 1917-18 with two infantry brigades, each of two regiments, had numeroussupporting units and reached a total of over 28,000 men.  Medicalpersonnel at the company, battalion, and regimental levels provided medicalcare the sick and wounded, but in time the battalion aid station underthe battalion surgeon came to be the focal point of life-saving medicalcare close to the front lines.  A sanitary train of four field hospitalsand four ambulance companies provided evacuation from the battlefield andthe medical service for the division under the overall command of a divisionsurgeon.

This section presents two excerpts from Volume VIII:  FieldOperations of The Medical Department of the United States Army in the WorldWar that describe the organization, doctrine, and operations of thedivisional medical service in the AEF.  Chapter IV, "Medical Serviceof the Division in Combat," details how the division's medical servicewas organized and functioned at the front, both in trench warfare and inopen warfare.  The second excerpt is drawn from the Appendix and containsthe abbreviations used, brief histories of the medical services and unitsof each of the divisions, and a list of the army and corps surgeons.
