Typically a white field would indicate 'the white path' (peace, tranquility, harmony) and red would of course indicate the 'red path' (war). However, it seems contradictory that the Pin (Keetoowah Society) members of Drew's Regiment (Confederate) who then defected to the Union would be carrying a 'peace flag'. I'm skeptical as to whether this was actually the flag of Drew's Regiment (given by Albert Pike). It seems much more likely Pike gave them a 1st National with 5 red stars for the so-called Five Civilized Tribes who were allied with the Confederacy (Cherokee, Choctaw, Chickasaw, Muskogee/Creek, Seminole). However, if Slover is correct, the blue moon is supposed to represent the Confederacy. Perhaps this was an adaptation of a Cherokee National flag as opposed to a Confederate or regimental flag. Supposedly the Cherokee exchanged flags with Pike, perhaps this was the design of the Cherokee flag he was given. I don't think I've ever seen a description of that flag.
