The newspapers at the time did have some casualty lists, however, they were not comprehensive or systematic by any stretch of the imagination. For example, one list I found for my regiment and brigade was submitted by one of the chaplains of the brigade. What was submitted by the regiment for a casualty report did not mean that they were hospitalized. They could have been returned to duty, died of wounds prior to being evacuated, etc. To make it even more complicated, the Confederates reported all wounds. Private Johnny Reb Snuffy received a cut finger but it was sewn up by the regimental surgeon and sent back to company he was classified as wounded.
What information are you particularly looking for? Day to day tasks? Rules and Regulations? Medical Triage? Care and Treatment? Civilian Relief Organizations? Names and locations of the hospitals?
Please let me know if you have any questions.
