If you have specific questions about the Patterson's 5th Alabama Cavalry, go ahead and ask. Example: there's no complete list of all the regiment's battles and skirmishes - not an accurate one, anyway. However, if you wanted to know where Patterson and his men were at a given time, somebody will have that information.

Research suggestion: if you're looking for certain officers and men, browse Confederate Miscellaneous records. Almost every officer and a good number of enlisted men have at least one record in what the National Archives once called Unfiled Papers and Slips.
