Art, speaking of markings on artillery pieces, I ran across the following:

Headquarters Hardee’s Corps, Army of Tennessee,
Tullahoma, April 20, 1863.

Col. George William Brent, Assistant Adjutant-General, Army of Tennessee.

Colonel—In obedience to instructions from headquarters of the army, I have the honor to forward herewith the names of officers who fell at the battle of Murfreesborough, conspicuous for their valor, to be inscribed on the battery of Liddell’s brigade, and on one of the reserve batteries:

Liddell’s battery.—Lieut. Col. Don. McGregor, 1st Arkansas; Capt. James T. Armstrong, Co. E, 6th Arkansas; First Lieut. H. C. Collier, Co. H, 2nd Arkansas, and First Lieut. H. J. McCurdy, 8th Arkansas.

Reserve Battery.—Maj. Henry C. Ewin, 44th Tennessee Regiment; Maj. James T. McReynolds, 37th Tennessee Regiment; Capt. E. Eldridge Wright, Wright’s battery, and Capt. Edwin Allen, Co. C, 26th Tennessee Regiment.

Very respectfully, your obedient servant,
W. J. HARDEE,
Lieutenant-General.

I don't think I've ever seen a reference like this before. Is Hardee ordering these names to actually be inscribed on the guns?
