Capt. Ferd Claiborne, 3rd Md., with four guns along with Taylor’s Brigade was sent to the R. R. bridge over B. Black. (195, 4/29 entry)

06 24 1863 [Wednesday]

Capt. F. O. Claiborn, commanding the 3rd Md. Battery was killed this day by a fragment from an enemy shell.

06 26 1863 [Friday] 40th Day of Siege

At eleven o’clock this Friday morning Capt. “Ferd” Osman Clairborne, Commanding the 3rd Maryland Battery, Reynold’s Brigade, was “buried in a plain black coffin, according to the forms of the Lutheran Church by Major Giesler of the 59th Tennessee Rifles, a licensed minister. The previous day, Ferd, who thought he glimpsed the foe approaching, borrowed a field telescope from his cousin and hurried to a forward artillery position. He had barely given an order to open fire when struck in the face by a shell fragment. That night Captain Clairborne’s body, in full uniform, lay in the commanding colonel’s tent, attended by an honor guard, as mourning comrades filed past. He was buried on a little knoll about 100 yards north of Reynold’s quarters. His burial was attended by the colonel and staff, the members of his company and a large number of devoted friends. All were more affected than I remember to have seen on any former occasion. The general [Col. Reynolds] wept like a child.

[I believe he was subsequently re-buried at his New Orleans home]

Back in 1999, I received a note from Skip Earle, formerly at the Carter House, Franklin, Tenn., working as an Historian. Relocated to Charlotte, N. C. He was at the time attempting to get a fully transcribed copy of Capt. William H. Claiborne's diary, Ferd's cousin, who makes note of working with Gen. Barton and other Georgia regiments.
