I have several files for CS Indian regimental flags. Additionally, the flags presented to the Indian Nations that allied with the CSA were also given what is called "treaty flags." Based on the written descriptions of the ones for which I have files, these were CS First Nationals with not only white stars for the CS states but also with upwards of 5 red stars for the Indian nations. I have seen one of these flags at the home of the late Howard Madaus when he was sent one for examination.
