I have the whole records (100 pages) of Capt. William W. Porter, CSA, ADC to Crittenden,Beauregard, Pope, Johnson, Hood. He is in the old cemetery here where I am the CW specialist on 165 CW vets (15 CSA). 2 weeks later he started over a year as an ADC to Johnson and was at Battle of Raymond where he took a Co. of 50th TN into the battle. Between generals he was for a time Enrollment Officer at Brookhaven, MS and the following telegram was sent to him;
"Jackson, April 28, 1863
Capt. W.W. Porter, Hazelhurst
Direct the two companies to follow up movement of the enemy, and you go with them by most expeditious route towards Grand Gulf. Should enemy divert, follow him up, taking care to keep on his flank or rear.
I have a note to myself that this was 2 companies of MS St. Cav. I believe this telegram may of been in reference to Col. Grierson's Raiders, U.S.
Can't find my original copy of the telegram now.
How many companies of the MS st Cav. were there?
