The peace thus made between the two tribes has never been broken, in which fact there may be a sermon for those who regard the Indian as faithless, when we consider how few European alliances have endured as long. The Pénätĕka Comanche, who lived far down in Texas, were not included in this compact and had very little connection even with the northern bands of their own people until brought together under the reservation system. Immediately after the treaty the Kiowa began to move down and make their camps along and south of the Arkansas, which, until that time, had been considered the northern boundary of the Comanche country and the southern limit of the Kiowa range. In the territory which they thenceforth held in common the Kiowa usually made their home camps more to the northwest, about the Arkansas, while the Comanche kept near to the Staked plains and the Texas frontier. Strengthened by their alliance for war and defense, the confederated tribes were now able to make a successful stand behind the Arkansas against further invasion from the north. The raids of the Kiowa on the Mexican settlements, hitherto desultory and ineffective, now became constant and destructive and continued until both tribes were finally subjugated and confined to their reservation after the outbreak of 1874. In these raiding expeditions they frequently made headquarters in the Sierra Madre, whence they descended upon the lower country on each side. Old men are still living in the tribe who have raided as far south as the city of Durango (which they know by this name) and southwest through Sonora and Sinaloa to the Gulf of California. These war parties would sometimes be absent two years. To the west they reached the great Colorado river and tell of killing some Havasupai in their canyon home. In the east they made captives on Matagorda bay, Texas. NEUTRAL ATTITUDE OF NEW MEXICANS According to the Kiowa and Comanche, whose statements are confirmed by abundant testimony from other sources, the inhabitants of New Mexico, from mercenary motives, usually held themselves neutral in this war on their brethren to the south. New Mexican _Comancheros_ and domesticated Pueblo Indians carried on a lucrative trade among these tribes at the same time that Kiowa or Comanche war parties were ravaging the southern provinces or selling horses and mules, taken in these raids, to the inhabitants of Las Vegas and neighboring towns. The lances and tomahawks used by their warriors were of Mexican manufacture, more slender and graceful in design than those supplied to the northern tribes by English and American traders. It was only by such tacit connivance or active aid from the people of New Mexico that these tribes were able to carry on an unceasing warfare of extermination as far south as Tamaulipas and Durango in Mexico.
