Wade,
All of the records I have located indicate that the following units of Sharp's Miss. High Pressure Brigade had not left Montgomery, AL by rail until March 9, 1865 for Augusta, GA so it is doubtful they participated in the action.
This information comes from a letter written by Capt. A.F. Davis Co. K 7th Miss. on March 8, 1865 to his wife Julia.
Once in Augusta they had a 200 mile march to reach Johnston's forces in NC. It is doubtful that any of the brigade fought in any actions other than possibly skirmishes; but no where in any of the regimental files are mentions of such actions. I know that doesn't help you except to eliminate the units.
The Brigade consisted of the Consolidated 9th Miss. (7th and 9th Miss. Inf.) under Col. Benjamin F. Johns, 10th Miss. Inf., 41st Miss. Inf., 44th Miss. Inf., 9th Battn. Miss. Sharpshooters. The brigade numbered 420 with the consolidated 9th having only 74 men at surrender.
If you do find any mention of these units, please let me know.
