PoD 1: During the Trail of tears, the other 4 civilized (the ones other than the seminole, also I know there were far more than those 5 that were civilized) tribes decide to fight tooth and nail to keep their land like the Seminole, dragging on the conflict making it known to the 700 or so Natives who sided with the USA against Black hawk and most (if not all of them) side with him instead (since they know about the war against the 5 civilized tribes and realize they will also be victimized by the whites even if they keep on siding with them, adopt their culture etc.) the combination of more men on Black hawk's side and more US soldiers fighting the ''5 civilized tribes'' makes it a much harder win for the US. but PoD2 should make it a win for black hawk.
PoD2: Before the war, Black hawk Conducts regular military drills and simulated battles, that would have allowed his forces to practice coordination, movement, and communication & realize that given the nature of the conflict and the disparity in resources, Black Hawk would have had 2 focus on guerrilla warfare tactics. Training in hit-and-run tactics, ambushes, and unconventional warfare might (and in combination with PoD 1, would) have countered the superior firepower of the U.S. forces.
