"The Conquest of New Mexico and California" is the title of an excellent and entertaining volume written in 1878 by Lieut.-Col. P. St. George Cooke, commander of the Battalion. It embraces much concerning the political features found or developed in both Territories and deals somewhat with the Kearny expedition and with the Doniphan campaign into Mexico that moved from Socorro two months after the Battalion started westward from the Rio Grande. Despite his eloquent acknowledgment of good service in the San Diego order, he had little to say in his narrative concerning the personnel of his command. In addition to the estimate of the command printed on a preceding page, he wrote, "The Battalion have never been drilled and though obedient, have little discipline; they exhibit great heedlessness and ignorance and some obstinacy." The ignorance undoubtedly was of military matters, for the men had rather better than the usual schooling of the rough period. At several points his diary gave such details as, "The men arrived completely worn down; they staggered as they marched, as they did yesterday. A great many of the men are wholly without shoes and use every expedient, such as rawhide moccasins and sandals and even wrapping the feet in pieces of woolen and cotton cloth." It is evident that to the Colonel's West Point ideas of discipline the conduct of his command was a source of irritation that eventually was overcome when he found he could depend upon the individuals as well as upon the companies. Several stories are told of his encounters in repartee with his soldiers, in which he did not always have the upper hand, despite his rank. Brusque in manner, he yet had a saving sense of humor that had to be drawn upon to carry off situations that would have been intolerable in his own command of dragoons.
