I am pulling together a data base of Ross' Brigade. Of course at Holly Springs the Bde was commanded by Colonel Whitfield and it was the first commitment of these four units together. Van Dorn Commanded the raid but Col Griffith of the Sixth led the 3rd and 6th on the charge into town, an honor given to him by Van Dorn for his design of the raid. It was a complete surprise and had they arrived a few minutes earlier, they could have captured General Grant. You could still see the smoke from his train when Griffith rode into town. They did have some words with Mrs. Grant. Read Victor Rose's book or Griscom's diary and Newton Keen's accounts or that of several other accounts. Van Dorn also did a report on the raid and it is an entry in the Southern Historical Society papers. The capture and destructiion of several million dollars of material and 2000 men, who they paroled rather than feed was off set a little by some of the troops who got out of hand and drank and pillaged.
Luckly there was no counter attack. But then us Texicans weren't known for our polish and demeener. My GGF, Robert A. Nolan and his Brother James Tyre Nolan were there, as near as I have been able to descern. This raid and the stopping of Sherman's march from Vicksburg to Mederian are two of the highest events of Ross' Bde though there were many others that are close.
