Doran resigned in December, 1862. This document was signed as of December 10, 1862. By then, by my count, 116 men had died in the unit since they left for Pittsburgh landing. That includes those wounded or killed in Corinth, of course, but that was about 6 of them, 10 if you count those who died from wounds. The rest died from typhoid, chronic diarrhea, or other sicknesses like them.
