Several regiments were engaged in Northern Missouri in guarding railroads and repressing guerrillas, and it was necessary that they should act in concert. Grant was the junior in rank of the other colonels; but as they had a reasonable delicacy in issuing orders to one who had been educated at West Point, and who had seen service on the battle-field, the commander of the Twenty-first was appointed acting brigadier. In the latter part of July the chaplain of his regiment informed Grant that he had been appointed a Brigadier General of Volunteers. He was quite surprised at the intelligence, for he had made no application for the promotion, either directly or through any of his friends. The appointment was obtained by Mr. Washburn, who had introduced him to Governor Yates. This gentleman exhibited a high appreciation of the abilities of Grant, and it could not but be a happy thought to him, in the light of subsequent events, that he had been instrumental in bringing forward the illustrious soldier, though I doubt not that, without the aid of any influence in his favor, he would in due time have soared to his proper level. As a regimental commander, Colonel Grant made his mark; for he always did everything well. He was acting in this capacity in order to serve his country, and not as a stepping-stone to future eminence. He discharged his duties earnestly and faithfully in this comparatively humble sphere, as though he had already reached the height of his ambition. He gave his men an example of the most rigid simplicity of manners. He rarely wore a uniform, except on parade, and was above any vain show of "fuss and feathers." Nothing ever moved him so that his emotion came to the surface, and when informed that he had been appointed a brigadier, he was as undisturbed as though the matter did not concern him. In his regimental experience, where he was more directly and intimately connected with the soldiers, he labored zealously to promote their welfare, morally and spiritually, as well as in a military point of view. He manifested a lively interest in the observance of the ordinances of religion among the men. He encouraged the chaplain in his efforts to keep the spirit of the gospel alive in the troops. He insisted upon having divine services in his camp, and used his influence to secure the attendance of all under his command. He regularly attended worship himself, except when prevented by his duties from being present. One day, at the mess table of the regiment, when the officers were all seated, Colonel Grant remarked that it was his custom, when at home, to invite any clergyman, who was present in his house, to ask blessing at the table, adding that a blessing was as much needed in the camp as at home, and, if it was agreeable to the views of his officers, he would like to have the chaplain ask a blessing every time they sat down to eat.
