Well I guess we may never know why it was left behind in a trunk. The hurry to evacuate? Someone thought someone else was getting it?...etc etc. Look at the 11th Ark at New Madrid/Fort Thompson. They also thought their luggage was going to be loaded and their flag and camp books etc were all left behind to be captured.
I wish I could find that tidbit that gave a very dim trail to the smaller ANV flag at the Old Statehouse possible being that of 2nd BN but I am at odds to find it. Seems like the flag is labeled as that of the Bailey collection that has the 3rd Ark flag and somehow the person that gave Bailey the flag for safe keeping had been part of the 2nd, but I can't for the life find that yet. hopefully it will turn up in my "stuff" again.
