The following is an excerpt from A. J. Brown's History of Newton County, Mississippi From 1834 to 1894 and published in 1894.
Please bear in mind the recollections of Mr. Doolittle and Mr. Walker were written well after the war's end. It should also be noted the second captain is listed as M. E. Blelack in this account although he signs his name as Blalock/Blaylock on official records.

Mr. C. H. Doolittle, who was a member of this company, and for a time the color-bearer, of the regiment, and Mr. I. W. Walker, now a citizen of Newton, and also a member of the company, furnish some valuable information.

Mr. Doolittle writes:
"The company was known as Perry's company; was Company B of the Fourth, but afterwards, the Second Mississippi Cavalry. J. J. Perry was captain from the organization, April, 1862, until December, 1863, when he was promoted to major. M. E. Blelack, who was first lieutenant, became captain of the company. The roster now stood: M. E. Blelack, captain; Dan'l Johnson, H. W. Todd, A. J. Smith, lieutenants. Johnson resigned and Joseph Jackson was elected as one of the lieutenants. This company, when it went out, had one hundred and eight men, and was recruited from time to time; also, some discharged. The Second Mississippi Cavalry served under Van Dorn, Forrest, and S. D. Lee. It was a part of Gen. Frank Armstrong's brigade, and was in eight or ten regular engagements, besides numerous skirmishes. Company B did the greater part of the skirmishing for the regiment, as it had what was considered the best officers."

Mr. Walker writes:
"The first engagement of this company was at Duck Hill; then at Rome, Georgia; then all through the Georgia campaign; then to Franklin and Nashville, and Columbia, Tenn.; and thence back to Alabama; surrendered at Selma. The company lost six killed, twelve or fifteen wounded."

This company stands very prominent among those who went to the army from Newton County. Capt. M. E. Blelack, who was a very large and fleshy man, looked to be unable for active service, but be it said to his honor that he was one of the bravest and most efficient officers that ever went from the county. He could have stayed at home, but he preferred to go and risk his life for the good of the Southern Cause.

Hope this helps,
