On November 25, 1864, Carson led his forces against the southwestern tribes at the First Battle of Adobe Walls in the Texas panhandle. Adobe Walls was an abandoned trading post blown up by its inhabitants to prevent a take-over by hostile Native Americans. Combatants at the First Battle were the United States Army and masses of Kiowas, Comanches, and Plains Apaches. It was one of the largest engagements fought on the Great Plains. The Texas State Library and Archives Commission writes: "The result of Adobe Walls was a crushing spiritual defeat for the Indians. It also prompted the U.S. military to take its final actions to crush the Indians once and for all. Within the year, the long war between whites and Indians in Texas would reach its conclusion."
