In midsummer of 1872, a Texas cattleman, John Hittson, led 50 hard-bitten cowboys on a vigilante-style raid of Eastern New Mexico, and he did so with the approval of his state governor. The incident created headlines at the time, but today it has been almost forgotten.
The trouble that prompted Hittson’s daring act had its origins in the famed Comanchero trade of the southern plains. Comancheros were native New Mexicans who, for more than a century, had been venturing upon the wide Llano Estacado to trade with the warlike Comanche Indians.
...When John Hittson finally departed New Mexico, he was said to be driving 18,000 head of cattle. It was not his raid that finished off the Comacheros, however. That task was completed by the army who soon forced the Comanche tribe onto an Oklahoma reservation. That ended their trading with the New Mexicans.
