There are no dates on his marker, just E. L. Richmond, Captain Confederate Army.
Col. John McGuirk and Lt. Col. James A. Barksdale commended Sgt. Major E. L. Richmond for gallantry and courage during Chalmers' Raid of Oct. 4-17, 1863. Both officers mention him in two reports, so that's four commendations total. These references come from the Official Records. There could be others in the O.R., but much of what's available is here --

In the governor's report of August 1864, we have the following --
On the fourth day of May last, I transferred to the Confederate army the brigade commanded by Gen. Gholson, composed of the regiments of Colonels McGuirk, Lowry and Ham, and the battalions of Lt. Col. Ashcraft and Major Harris. I permitted the men transferred to retain the horses belonging to the State, with the understanding that the officers were to be responsible for the payment of one hundred dollars for each horse. These troops have distinguished themselves in battle in our defence. I recommend that all the horses in the possession of Gen. Gholson's brigade, and the other regiments that have been transferred, be presented to them. and the officers be released from their obligations.
