Today's Adventure in Texas, Parte the Thirde.
After reading about a fight between thirty two settlers and natives, as told thirty years after the fact in 1890 (meaning the fight was in 1860), I tried for several years to find this site. I'm 90% sure this is it.
The keys were "a peak in front of a mountain range" "crossing a creek at a fork" and "Seco Canyon." There were several places whefre these fit, but this one fit best. My only real concern is that the article mentions that they visited a site "two miles above the Bandera Road"which WASN'T the site, and this site sits about three miles above FM 470 (Or the old Bandera Road).
