Civil War Doctors
The state of medical knowledge at the time of the Civil War was extremely primitive. Doctors did not understand infection, and did little to prevent it. It was a time before antiseptics, and a time when there was no attempt to maintain sterility during surgery. No antibiotics were available, and minor wounds could easily become infected, and hence fatal. While the typical soldier was at very high risk of being shot and killed in combat, he faced an even greater risk of dying from disease.
