Several members of McDonald's company received paroles at Montgomery, Ala. Dates for these paroles range for almost a month between later May to mid-June 1865. Some parolees describe the company as "Reserves".

Because this company was raised late in the war for special purposes, it will not appear in anyone's records. In 1860 John T. McDonald was a clerk, age 26, living in the City of Montgomery. He also appears on the 1870 census of Montgomery. On March 28, 1862 McDonald joined the "Fireman's Guards", a local militia command. In August 1862 he joined Capt. M. L. Kirkpatrick's Cavalry Company, assigned to the 51st Alabama Mounted Regiment as Co. "H". By the following summer he had been detailed to return to Montgomery as an enrolling officer (but still an enlisted man). In late July of 1864 a company of exempts was organized as Supporting Forces for the Conscript Bureau in the Sixth Congressional District. McDonald was appointed 1st Lieutenant, Thomas S. Herbert of Hayneville, Ala., becoming Captain. Herbert was a retired Confederate officer. having lost an arm due to wound received at Seven Pines,, Va., May 31, 1862. At the time he was 1st Lieutenant of Co. "K", 5th Alabama Regiment.

I gave you information about counties in the 6th Congressional District which apparently did not apply to Alabama as a Confederate state. When Alabama joined the Confederacy, nine congressional districts were organized, so counties were reassigned.

Rep. Chilton, a resident of Talladega County, was elected to the Confederate Congress from this district. Capt. Herbert was from Lowndes and Lieut (later Captain) McDonald was from Montgomery, so Coosa County could have been included.

During the summer of 1864, Major E. Herbert Armistead of the 22nd Alabama was the officer in charge of this district. He signed many of the requisitions for this command, most dated from August and September of 1864, Montgomery, Ala. These are all found in Unfiled Slips and Papers (miscellaneous) because they do not belong to a recognized Confederate military command.

I hope this finally answers your questions.
