It is so confusing with captured Union flags. It was very rare that Union regimental commanders admitted to losing a flag. Very rare they admitted it in their regimental history books as well. So, I have to go off of CSA accounts of flags they captured. If they did not list what or who's flag it was, then its just detective work.
I am still filling in all Union states that lost flags. New York, Pennsylvania, Ohio, Illinois and Indiana lost the most, since they put the most regiments on the field. Minnesota, Vermont, Rhode Island and New Hampshire, the fewest.
Welcome to my hell, lol
Have a good day, Sir
