TDM, it’s not been long since I read a lot about the Creek wars in Albert James Pickett's book, History of Alabama and incidentally of Georgia and Mississipp. Copyright is in the 1850's So it was written not long after the division of the Mississippi territory. Pickett had knowledge directly from some of those involved in the war. His history is in two lengthy volumes but you will gain much by reading vol. 1 first to give you the setting for the Creek war itself. You can get both as free PDF downloads at archive.org. Excellent read.
