While not officially a battle of the Red River War, The Second Battle of Adobe Walls was arguably the reason there was a Red River War. This 1874 conflict on the Texas Panhandle Plains was between several hundred Comanche, Cheyenne, and Kiowa warriors and 28 buffalo hunters using .50 caliber, "Big 50" rifles. It is an unusual event marked by courage, audacity, and ego; an explosion of cultures marking a procession of civilization that was going to happen.

The Second Battle of Adobe Walls was a major engagement immediately prior to the official start of the Red River War involving a large number of Indians, 28 buffalo hunters, and one woman. The battle was initiated through an attack at dawn by a stronghold of Comanche, Cheyenne, and Kiowa Indians in the Texas Panhandle in an audacious effort to stop buffalo hunting and to maintain the open range lifestyle they'd enjoyed for centuries. In 1874 there were only about 350,000 Native Americans in the entire contiguous United States. With millions of Americans moving west, more modern technology, and a bad medicine man, the attack was doomed. The Second Battle of Adobe Wals helped trigger the Red River War which ultimately crushed Native American resistance.
