Organization of the Battalion
Col. Stephen W. Kearny, commanding the First Dragoon regiment, then stationed at Fort Leavenworth, selected Capt. James Allen of the same regiment to be commander of the new organization, with volunteer rank as lieutenant-colonel. The orders read: "You will have the Mormons distinctly understand that I wish to have them as volunteers for twelve months; that they will be marched to California, receive pay and allowances during the above time, and at its expiration they will be discharged, and allowed to retain as their private property the guns and accouterments furnished them at this post."
Captain Allen proceeded at once to Mount Pisgah, a Mormon camp 130 miles east of Council Bluffs, where, on June 26, 1846, he issued a recruiting circular in which was stated: "This gives an opportunity of sending a portion of your young and intelligent men to the ultimate destination of your whole people at the expense of the United States, and this advance party can thus pave the way and look out the land for their brethren to come after them."
July 16, 1846, five companies were mustered into the service of the United States at Council Bluffs, Iowa Territory. The company officers had been elected by the recruits, including Captains Jefferson Hunt, Jesse B. Hunter, James Brown and Nelson Higgins. George P. Dykes was appointed adjutant and William McIntyre assistant surgeon.
The march westward was started July 20, the route through St. Joseph and Leavenworth, where were found a number of companies of Missouri volunteers. Colonel Allen, who had secured the confidence and affection of his soldiers, had to be left, sick, at Leavenworth, where he died August 23.
At Leavenworth full equipment was secured, including flintlock muskets, with a few caplock guns for sharpshooting and hunting. Pay also was drawn, the paymaster expressing surprise over the fact that every man could write his own name, "something that only one in three of the Missouri volunteers could accomplish." August 12 and 14 two divisions of the Battalion left Leavenworth.
Cooke Succeeds to the Command
The place of Colonel Allen was taken, provisionally, by First Lieut. A. J. Smith of the First Dragoons, who proved unpopular, animus probably starting through his military severity and the desire of the Battalion that Captain Hunt should succeed to the command. The first division arrived at Santa Fe October 9, and was received by Colonel Doniphan, commander of the post, with a salute of 100 guns. Colonel Doniphan was an old friend. He had been a lawyer and militia commander in Clay County, Missouri, when Joseph Smith was tried by court martial at Far West in 1838 and had succeeded in changing a judgment of death passed by the mob. On the contrary, Col. Sterling Price, the brigade commander, was considered an active enemy of the Mormons.
At Santa Fe, Capt. P. St. George Cooke, an officer of dragoons, succeeded to the command, as lieutenant-colonel, under appointment of General Kearny, who already had started westward. Capt. James Brown was ordered to take command of a party of about eighty men, together with about two-score women and children, and with them winter at Pueblo, on the headwaters of the Arkansas River. Fifty-five more men were sent to Pueblo from the Rio Grande when found unable to travel.
Colonel Cooke made a rather discouraging report on the character of the command. He said:
