His command was a body of three months' troops, composed of excellent material, but in rather a demoralized condition when the colonel assumed command, for the men were American citizens, jealous of their rights as such, and military discipline was new and strange to them. Grant marched them to Caseyville, where he drilled them for four weeks, and transformed them from a mob of independent citizens into one of the best-disciplined bodies of troops in the country, which became noted for its orderly and excellent bearing. The change was effected so skilfully that no man believed he had sacrificed his citizenship. The strong will of the colonel, dignified by the genuine principle of patriotism, overcame the prevailing idea of equality, and his command was a unit. The men were proud of the leadership of a regular army officer, and admired him to such a degree that they re-enlisted for three years. While Colonel Grant was at Caseyville it was reported that Quincy, on the Mississippi, was menaced by rebel guerillas from Missouri, and he was ordered to the exposed point. In the absence of transportation he marched his regiment one hundred and twenty miles of the distance. From this point his command was sent into Missouri, where the discipline and the morals of the body were improved by quiet and judicious measures. Guarding railroads was the service in which the regiment was employed; and when serving with other commands Grant was the acting brigadier-general, though he was ranked by all the other colonels. In July of the opening year of the war Grant became a brigadier-general of volunteers. The appointment was obtained by Mr. Washburn, who had befriended him before. The Western Department was at this time under the command of General Fremont. Grant's district was a part of Missouri, with Western Kentucky and Tennessee, and he established his head-quarters at Cairo, a point of the utmost military importance as a depot of supplies and a gunboat rendezvous. Kentucky had proclaimed a suspicious neutrality, and near Cairo, on the other side of the river, were the three termini of a railroad from the South. A Confederate force seized two of them, and Grant hastened to secure Paducah, the third. The enemy hurriedly retired as he landed his force, and Grant issued a temperate and judicious proclamation, for he was on the soil of the enemy. He had acted without orders from his superior, and returning to Cairo after an absence of less than a day, he found Fremont's order, already executed, awaiting him. He also took possession of Smithland, at the mouth of the Cumberland River.
