Unfortunately much of the CS Medical Service records that existed went up in smoke in the Surgeon Generals Office in Richmond at the end of the war. Resulting in massive gaps and voids in the records. If a Medical Officer was assigned to a given Regiment, sometimes a bit more data... If they were assigned to a post, hospital or wayside, generally not as much. Other than the fragmented secondary items such as surviving QM records and requisitions for forage, fuel, transportation, which might give glimpses as to a given time and place. Some appointment and promotional mentions from war department records or other period publications. Many times that's all that's remaining.

Day books, case books and various records that did survive from various hospital facilities were confiscated along with many other confederate documents and records, forwarded to the war dept at the end of the war. Unfortunately many of these medical related records that could provide us with vital information.... were gathered up and deposited without regard or notation to where they actually came from, nor marked within. National Archives has tons of these unidentified, unsorted, un-cataloged medical facility records and books all mixed together.
