As early as November, 1842, a rumour was current in Santa Fe, and along the line of the Trail, that parties of Texans had left the Republic for the purpose of attacking and robbing the caravans to the United States which were owned wholly by Mexicans. In consequence of this, several Americans were accused of being spies and acting in collusion with the Texans; many were arrested and carried to Santa Fe, but nothing could be proved against them, and the rumours of the intended purposes of the Texans died out.

Very early in May, however, of the following year, 1843, a certain Colonel Snively did organize a small force, comprising about two hundred men, which he led from Northern Texas, his home, to the line of the Trail, with the intention of attacking and robbing the Mexican caravans which were expected to cross the plains that month and in June.

When he arrived at the Arkansas River, he was there reinforced by another Texan colonel, named Warfield with another small command. Gregg says:

Kit Carson figured conspicuously in this fight, or, rather, immediately afterward. His recital differs somewhat from Gregg's account, but the stories substantially agree. Kit said that in April, previously to the assault upon Armijo's caravan, he had hired out as hunter to Bent's and Colonel St. Vrain's train caravan, which was then making its annual tour eastwardly. When he arrived at the crossing of Walnut Creek,22 he found the encampment of Captain Philip St. George Cooke, of the United States army, who had been detailed with his command to escort the caravans to the New Mexican boundary. His force consisted of four troops of dragoons. The captain informed Carson that coming on behind him from the States was a caravan belonging to a very wealthy Mexican.

It was a richly loaded train, and in order to insure its better protection while passing through that portion of the country infested by the blood-thirsty Comanches and Apaches, the majordomo in charge had hired one hundred Mexicans as a guard. The teamsters and others belonging to the caravan had heard that a large body of Texans were lying in wait for them, and intended to murder and plunder them in retaliation for the way Armijo had treated some Texan prisoners he had got in his power at Santa Fe some time before. Of course, it was the duty of the United States troops to escort this caravan to the New Mexico line, but there their duty would end, as they had no authority to cross the border. The Mexicans belonging to the caravan were afraid they would be at the mercy of the Texans after they had parted company with the soldiers, and when Kit Carson met them, they, knowing the famous trapper and mountaineer well, asked him to take a letter to Armijo, who was then governor of New Mexico, and resided in Santa Fe, for which service they would give him three hundred dollars in advance. The letter contained a statement of the fears they entertained, and requested the general to send Mexican troops at once to meet them.

Carson, who was then not blessed with much money, eagerly accepted the task, and immediately started on the trail for Bent's Fort, in company with another old mountaineer and bosom friend named Owens. In a short time they arrived at the Fort, where Owens decided not to go any further, because they were informed by the men at Bent's that the Utes had broken out, and were scattered along the Trail at the most dangerous points, and he was fearful that his life would be endangered if he attempted to make Santa Fe.

Kit, however, nothing daunted, and determined to do the duty for which he had been rewarded so munificently, started out alone on his perilous trip. Mr. Bent kindly furnished him with the best and fastest horse he had in his stables, but Kit, realizing the dangers to which he would be exposed, walked, leading his animal, ready to mount him at a moment's notice; thus keeping him in a condition that would enable Carson to fly and make his escape if the savages tried to capture him. His knowledge of the Indian character, and wonderful alertness in moments of peril, served him well; for he reached the village of the hostile Indians without their discovering his proximity. Hiding himself in a rocky, bush-covered canyon, he stayed there until night came on, when he continued his journey in the darkness.

He took the trail to Taos, where he arrived in two or three days, and presented his letter to the alcalde, to be sent on to Santa Fe by special messenger.

He was to remain at Taos until an answer from the governor arrived, and then return with it as rapidly as possible to the train. While at Taos, he was informed that Armijo had already sent out a company of one hundred soldiers to meet the caravan, and was to follow in person, with a thousand more.

This first hundred were those attacked by Colonel Snively, as related by Gregg, who says that two survived, who carried the news of the disaster to Armijo at Cold Spring; but Carson told me that only one got away, by successfully catching, during the heat of the fight, a Texan pony already saddled, that was grazing around loose. With him he made Armijo's camp and related to the Mexican general the details of the terribly unequal battle. Armijo, upon receipt of the news, "turned tail," and retreated to Santa Fe.

Before Armijo left Santa Fe with his command, he had received the letter which Carson had brought from the caravan, and immediately sent one in reply for Carson to carry back, thinking that the old mountaineer might reach the wagons before he did. Carson, with his usual promptness, started on the Trail for the caravan, and came up with it while it was escorted by the dragoons, thus saving it from the fate that the Texans intended for it, as they dared not attempt any interference in the presence of the United States troops.

The rumour current in Santa Fe in relation to a probable raid of parties of Texans along the line of the Trail, for the purpose of attacking and robbing the caravans of the wealthy Mexican traders, was received with so little credence by the prominent citizens of the country, that several native trains left for the Missouri River without their proprietors having the slightest apprehension that they would not reach their destination, and make the return trip in safety.

Among those who had no fear of marauders was Don Antonio Jose Chavez, who, in February, 1843, left Santa Fe for Independence with an outfit consisting of a number of wagons, his private coach, several servants and other retainers. Don Antonio was a very wealthy Mexican engaged in a general mercantile business on a large scale in Albuquerque, who made all his purchases of goods in St. Louis, which was then the depot of supplies for the whole mountain region. He necessarily carried with him on these journeys a large amount of money, in silver, which was the legal currency of the country, and made but one trip yearly to replenish the stock of goods required in his extensive trade in all parts of Mexico.

Upon his arrival at Westport Landing, as Kansas City was then called, he would take the steamboat for St. Louis, leaving his coach, wagons, servants, and other appointments of his caravan behind him in the village of Westport, a few miles from the Landing.

Westport was at that time, like all steamboat towns in the era of water navigation, the harbor of as great a lot of ruffians as ever escaped the gallows. There was especially a noted gang of land pirates, the members of which had long indulged in speculations regarding the probable wealth of the Mexican Don, and how much coin he generally carried with him. They knew that it must be considerable from the quantity of goods that always came by boat with him from St. Louis.

At last a devilish plot was arranged to get hold of the rich trader's money. Nine men were concerned in the robbery, nearly all of whom were residents of the vicinity of Westport; their leader was one John McDaniel, recently from Texas, from which government he claimed to hold a captain's commission, and one of their number was a doctor. It was evidently the intention of this band to join Warfield's party on the Arkansas, and engage in a general robbery of the freight caravans of the Santa Fe Trail belonging to the Mexicans; but they had determined that Chavez should be their first victim, and in order to learn when he intended to leave Santa Fe on his next trip east, they sent their spies out on the great highway.

They did not dare attempt their contemplated robbery, and murder if necessary, in the State of Missouri, for there were too many citizens of the border who would never have permitted such a thing to go unpunished; so they knew that their only chance was to effect it in the Indian country of Kansas, where there was little or no law.

Cow Creek, which debouches into the Arkansas at Hutchinson, where the Atchison, Topeka and Santa Fe Railroad crosses the historic little stream,23 was, like Big and Little Coon creeks, a most dangerous point in the transcontinental passage of freight caravans and overland coaches, in the days of the commerce of the prairies. It was on this purling little prairie brook that McDaniel's band lay in wait for the arrival of the ill-fated Don Antonio, whose imposing equipage came along, intending to encamp on the bank, one of the usual stopping-places on the route.

The Don was taken a few miles south of the Trail, and his baggage rifled. All of his party were immediately murdered, but the wealthy owner of the caravan was spared for a few moments in order to make a confession of where his money was concealed, after which he was shot down in cold blood, and his body thrown into a ravine.

It appears, however, that the ruffians had not completed their bloody work so effectually as they thought; for one of the Mexican's teamsters escaped, and, making his way to Leavenworth, reported the crime, and was soon on his way back to the Trail, guiding a detachment of United States troops in pursuit of the murderers.

John Hobbs, scout, trapper, and veteran plainsman, happened to be hunting buffalo on Pawnee Fork, on the ground where Larned is now situated, with a party from Bent's Fort. They were just on the point of crossing the Trail at the mouth of the Pawnee when the soldiers from Fort Leavenworth came along, and from them Hobbs and his companions first learned of the murder of Chavez on Cow Creek. As the men who were out hunting were all familiar with every foot of the region they were then in, the commanding officer of the troops induced them to accompany him in his search for the murderers.

Hobbs and his men cheerfully accepted the invitation, and in about four days met the band of cut-throats on the broad Trail, they little dreaming that the government had taken a hand in the matter. The band tried to escape by flight, but Hobbs shot the doctor's horse from under him, and a soldier killed another member of the band, when the remainder surrendered.

The money, about twelve or fifteen thousand dollars,24 was all recovered, and the murderers taken to St. Louis, where some were hung and some imprisoned, the doctor escaping the death penalty by turning state's evidence. His sentence was incarceration in the penitentiary, from which he was pardoned after remaining there two years. Hobbs met the doctor some years after in San Francisco. He was then leading an honest life, publishing a newspaper, and begged his captor not to expose him.

The money taken from the robbers was placed in charge of Colonel Owens, a friend of the Chavez family and a leading Santa Fe trader. He continued on to the river, purchased a stock of goods, and sent back the caravan to Santa Fe in charge of Doctor Conley of Boonville, Missouri.

Arriving at his destination, the widow of the deceased Chavez employed the good doctor to sell the goods and take the sole supervision of her immense business interests, and there is a touch of romance attached to the terrible Kansas tragedy, which lies in the fact that the doctor in about two years married the rich widow, and lived very happily for about a decade, dying then on one of the large estates in New Mexico, which he had acquired by his fortunate union with the amiable Mexican lady.
