I went back and did a word find search on the rosters of the Hampton Legion Infantry (which includes the Field and Staff of the whole Legion to mid-1862), and I have identified 50 men who are identified in some reputable source as physicians/doctors, or who were medical students at the time of enlistment (3). Of those 50, ten were appointed surgeons or assistant surgeons in the Provisional Confederate army (assigned either with the Legion or other units), and I can identify a specific medical school from which 9 of them graduated; I suspect that the tenth did as well, from either Jefferson Medical University of the Univesity of Pennsylvania Medical School.

Of the reamining 37, odentified in some way as doctors, 15 cannot be identified as having graduated form a medical school. Now I am sure that I have missed some, but there seems to be a substantial number of men who did not receive formal medical training. In the war, most of them actually served as privates in the ranks. But I ahve found that men assigned to duty as hospital stewards very frequently were actually doctors, which certainly enhanced the quality of care that the sick and wounded wound have received. Another doctor, serving as a private in the ranks, was killed at Gaines Mill while serving as a litter bearer. There appears to be some method in the madness of assigning medical-related eprsonnel.

This data is porovisional, and cannot be necessarily representative of what was going on in the Confederate army as a whole, but it is interesting.
