As best I can tell, you're asking about old Company "I", the "Clayton Guards" of Barbour County. Governor Moore issued Alabama Volunteer Corps commissions to Capt. M. B. Fenn and his lieutenants on Mar. 26, 1860. The company entered state service at Eufaula AL, Jan. 18, 1861, electing James W. Mabrey as captain. Officers and men transferred to Confederate service on Apr. 5, 1861, mustering out at Pensacola FL, Jan. 16, 1862.
On Feb. 10, 1862, officers and men electing to continue their relationship with this command assembled with recruits to organize new Company "F" at Clayton AL. Former members reenlisted for two years or the war. Three new companies arrived with the veterans in Memphis TN, Mar. 12, 1862. Praised as “Bragg’s best artillerists,” they were immediately sent to Island Ten on the Mississippi River.
The regiment surrendered with the Confederate garrison of Island Ten at Tiptonville TN, Apr. 8, 1862. Members who escaped captivity formed three provisional companies at Fort Pillow TN, Apr. 17, 1862. Prisoners were released near Vicksburg MS, Sept. 20, 1862, and regimental staff appointed on Oct. 22, 1862. The regiment surrendered again at Port Hudson LA, July 9, 1863, officers going to prisoner-of-war camps, while enlisted men were released on exchange, July 14, 1863.
Richard Williams was Captain of new Company "F". He commanded provisional Company “C” from Apr. 20, 1862, to Sept. 20, 1862. Captured at Port Hudson LA, July 9, 1863; paroled using an enlisted man’s name, July 14, 1863. Captured at Franklin TN, Nov. 30, 1864; escaped about Dec. 6, 1864. Paroled at Houston TX, June 27, 1865.
Combined with the 16th, 26th and 45th Alabama Infantry Regiments on Apr. 9, 1865, the 1st Alabama became part of the consolidated 1st Alabama Regiment. This command surrendered at Greensboro NC, May 1, 1865. Survivors of Company "F" surrendered with Company “A” of the consolidated 1st Alabama Regiment. That's the 3rd and final edition of these companies.
