There was an excellent exhibit in Orlando about this very subject 18 months ago. I wrote several articles which appeared in "Reflections" ( newsletter for Central Florida Historical Society) There were many small raids and expeditions to central Fla during the war, and yes cattle operations were very important. If you need specifics let me know, I have the largest private Civil War library in central Fla if not the state. I can be reached at 407-497-5485.
