Greg,
Here I am trying to locate one 12 Company regiment from the 15 to the 20th of February, 1863. This unit had participated in the Holly Springs Raid. Earl Vam Dorn was moving his Corps to Tennessee. This one regiment has a report of one battle in the time frame stated at Yaxoo Pass. Surely after 149 years, you guys have resolved the campaigns, but apparently not. For I have now read 3 versions. On the Texas board, it was noted that VNMP Vicksburg Order of Battle Had only Two regiments at Yazoo Pass and The 1st Texas Legion (aka the 27th Texas Cavalry Regiment) was not listed. Waul's Texas Legion was listed, and I am betting that the 27th was the Legion there and VNMP made another mistake, as they did on Bridge's Arkansas Battalion, which was made up of two Texas and one Missouri Cavalry Companies. The two Texas Companies were from Waul's Regiment. That battalion was outside the perimeter of Vicksburg under the control of S.D. Lee, and Bridges did not command the battalion until March 1863 when he return from wounds received at Corinth. By that time Ed Hawkins had taken the 27th to Tennessee to catch up with Van Dorn,

My question is what did the 27th do at Yazoo Pass from the 16th to the 20th. That they were there comes from the National Archives, but that organization also has mistakes, so any help would be appreciated.
