From Blood and Thunder: The Epic Story of Kit Carson and the Conquest of the American West, by Hampton Sides (Anchor, 2007), Kindle Loc. 551-568:
Kearny perceived, with a clarity rare among frontier soldiers of his generation, that alcohol was destroying the American Indian. Everywhere he went on the prairies, in his summits with the Plains tribes, he made “firewater” one of his central themes. “You have many enemies about you but this is the greatest of them all,” he once said in council with the Sioux. “Open your ears now and listen to me. Whenever you find it in your country, spill it all upon the ground. The earth may drink it without injury but you cannot.”
Kearny’s experience with Plains Indians was vast and yet, so rare in the brutal history of the West, his encounters were happily uneventful. Among the Plains tribes he was known as Shonga Kahega Mahetonga, Horse Chief of the Long Knives. He’d dealt with the Crows, the Blackfeet, the Chippewa, the Mandan, the Pawnee, the Winnebagos, the Potawatomi, the Sac and Fox, and scores of other tribes and moieties—almost always without bloodshed. Sometimes he fought against them, but more often he tried to referee the various Plains tribes in their time-honored wars against one another—or in their newer wars against the freshly arrived Cherokees, Chickasaws, and other so-called “civilized tribes” that the United States had force-marched from the East in the 1830s to live in the immense, if vaguely defined, Permanent Indian Frontier. Not surprisingly, the tragic U.S. policy of transplanting woodland Indians with an entirely alien culture and grafting them by fiat onto the unfamiliar world of the prairie had pried open a Pandora’s box of tensions—tensions that Kearny spent the bulk of his years as a young officer trying to understand and, to the extent possible, resolve. As one historian succinctly put it, Kearny and his contemporaries in the frontier army were charged with the thankless task of “imposing a Pax Americana on the entire artificial, ill-amalgamated Indian nation which the government had created.”
A diplomat by nature and an officer possessed of a Job-like patience, Kearny was the right man for this kind of work. His career was marked by persistence, discretion, and tolerance. There was about all his actions a distinct “absence of swashbuckling,” as biographer Dwight Clarke phrased it. It was that quality, perhaps more than anything else, that kept his invasion of New Mexico in 1846 from devolving into a disaster.
