I had been following this closely. I just released a novel based on the black/Creek Indian Rufus Buck, who formed a teenaged gang in 1895 to reclaim Indian lands and went on a 13 day rampage to accomplish his goal. Research showed a fascinating period in black history, little known and rarely discussed. The relationships between blacks and Indians varied from tribe to tribe, but to attempt to deny it is grotesque.
