Barbiere's Cavalry Battalion, Local Defense Troops [Alabama Reserves]

Major Joseph Barbiere's Cavalry Battalion was organized in 1864 from several independent companies which had themselves been created as supporting forces for the Conscript Reserves. The battalion served principally in central Alabama during the fall and winter, 1864-1865, and it was first assigned (1 Nov 64) to Armistead's Cavalry Brigade, District of Central Alabama, until January 1865. The unit was headquartered at Wilsonville, AL (Feb 65) and was reported as serving with the Alabama Reserves with six companies ("A"-"F"). It was assigned to, and included in the surrender of the Department of Alabama, Mississippi and East Louisiana by Lt. Gen'l Richard Taylor at Citronelle, AL, on 4 May 1865.
