A very good source of information on the regiments travels is found in Broadfoot's Supplement of the Offical Records, in their volumes covering unit Record of Events, see:

Record of Events for Forty-sixth Mississippi Infantry (formerly Balfour's Sixth Battalion),
November 1861-June 1865.

It is too long to copy on this message board.

This 100 volume set will be found in major university and city libraries. Contact Broadfoot Publishing Company, Wilmington, NC, to ascertain organizations in your neck of the woods that hold the set.
