I don't believe Smith's column included a cavalry component at this point. After defeating the 15th Confederate at Mount Pleasant on April 11th, Gen. Thomas J. Lucas returned to Stockton AL for refit and resupply. A few days later he advanced to Montgomery, a battalion of the 1st Louisiana (U.S.) Cavalry encountering members of Forrest's escort along the way near Camden.
In the report filed by Brig. Gen. Thomas J. Lucas, he writes,
In pursuance of requirements of Special Field Orders, No. 5, extract II, headquarters Cavalry Forces, Military Division of West Mississippi, Montgomery, May 10,1865, my command marched at 7 a. m. on the 11th of May, crossing the Alabama River by the pontoon bridge and moving to Kingston to await further instructions. The roads were found in a very bad condition, and forage scarce. Camped at Kingston same afternoon. Next day, having orders to move to Centerville, the command marched at an early hour, arriving at that place in two days, taking the Maplesville road with a portion of the column, the remainder, under Colonel Moore, Fourth Wisconsin Cavalry, moving via Plantersville. A portion of the command crossed the Cahawba River same night.
O.R., ser I, vol. XLIX, part 1, p. 303.
At this point the command under Lucas included the 2nd Illinois Cavalry, 10th Indiana Cavalry, 1st Louisiana (U.S.) Cavalry and 4th Wisconsin Cavalry. There is no suggestion in the reoprt of encountering any resistance whatsover along the line of march north of the Alabama River, not in Autauga County or anywhere else.
