Does anyone know any more specifics on what is referenced before being part of Ferguson's Brigade:

"The Second Alabama cavalry was organized at Montgomery in May,
1862; was in north Alabama for a short time and was then sent to
Florida, where it was employed for a time; sent to Jackson,
Miss., in April, 1863, and fought Grierson; was employed in
Mississippi until October of that year, when it was sent to
northern Alabama and Tennessee. "

It proceeded to West Florida and operated there about ten months, engaging in several skirmishes. Ordered to north Mississippi, the regiment was placed with Brig. Gen'l Daniel Ruggles. It then lost 8 men in a skirmish at Mud Creek.
