See if this helps:

Company C, at least (the escort company), was with General Chalmers in the campaign under General Forrest, with Hood's army, in Tennessee, November and December 1864. When General Schofield was retreating in the presence of the Confederate army from Columbia to Franklin, Forrest, after driving Hatch's Cavalry back toward Nashville, attacked the infantry column at Spring Hill to hold it in check until the Confederate infantry could come up.

In the evening, Forrest asked Chalmers to charge, and gave him Wilson's Regiment to support his escort company, which made the charge, but found, as Chalmers had urged, that the infantry were present in force, in the woods. General Chalmers wrote in a personal letter, describing the incident as one of the most memorable feats of the war: "Lieut. Elbert Oliver, of my escort company, was shot in the foot at one side of me, and Carson, my bugler, was severely wounded on the other side of me. You (Frank Norfleet) and I together, making a circuit so as to get out of the line of fire, galloped back to General Forrest, who said to me, 'they were there sure, enough.'"
