I have said that Grant had been appointed quartermaster of his regiment. As the officer in charge of the baggage trains of the force, well-established precedents permitted him to remain in charge of them during the fierce conflict, and thus to escape the personal peril of being under fire. It would not have been dishonorable, or an imputation upon his courage, for him to do so; but to his honor and glory be it said, that he never took advantage of his non-belligerent position. He always joined his regiment when it was summoned to the strife, and "behaved with distinguished gallantry" on all occasions. For his conduct on this eventful day he was promoted to the rank of full first lieutenant.

The Castle of Chapultepec was bombarded, and then carried by storm, after the walls had been breached. In the complicated details of the final attack the Fourth Infantry acted a worthy part. Grant assisted in serving a howitzer, mounted on the top of a convent, by which the enemy was considerably annoyed. It was a novel position for an infantry officer; but this was not the first, and by no means the last, time he was where he was least expected to be found—in front of the enemy. Colonel Garland, commanding the First Brigade on this occasion, officially says, "I must not omit to call attention to Lieutenant Grant, of the Fourth Infantry, who acquitted himself most nobly upon several occasions under my own observation."

The result of that gallant attack shows that all the officers behaved well; so well that Grant and one other only are mentioned out of the whole First Brigade, and the quality of the deeds which called forth the generous compliment of his superior may be judged from this fact. All had been brave to recklessness, all had been earnest and persevering; but it was the nature of Grant, even then, to surpass the bravest, the most earnest and persevering. In General Worth's report of the battle, he also speaks in commendation of the gallant lieutenant. For Grant's honorable mention he received the brevet rank of captain, to date from the day of the battle of Chapultepec.

With this strong fortress fell the city of Mexico; and during the night which followed its capture, the remains of the army of Santa Anna, with the civil officers of the government, fled to a place of safety. On the following morning, Scott and his gallant little army marched into the capital. The American flag floated proudly over the walls of the national capital, and Mexico was conquered; victory had constantly perched upon our banners, and we stood in the Halls of the Montezumas, where we were permitted to repose in peace after the battle summer through which we had just passed.

Grant remained in the city of Mexico while the negotiations for peace were in progress. As usual, he had a very spirited horse, for he never rode any other when one could be obtained. A Mexican gentleman, with whom he was on terms of friendly intimacy, desired to borrow this animal for a ride. Grant feared that the worthy señor could not handle the fiery steed; but it was not prudent to decline the request, for the Spanish nature of the applicant would take offence, and misjudge his motives in the refusal. The Mexican mounted the horse, but, when he had ridden a short distance, was thrown off and instantly killed.

Long ago I came to the conclusion that it is not safe for any man to attempt to ride Grant's horses, in a literal or a figurative sense.

Grant's mission in Mexico was finished. In that rapid and brilliant campaign from Vera Cruz to the capital, he had practically learned the lesson of war, and prepared himself for the great work he was to accomplish at a later period of his life, when West Point was to be divided between the opposing armies, when the most brilliant genius and the most determined energy alone could win victories. The importance of this season of actual duty in the field, in all the details of siege, march, and garrison duty, can hardly be over-estimated. In the war of the Great Rebellion he came into the field a trained soldier, with the teachings of experience stored up for use in a broader sphere of action than he or any of his companions in arms had yet dreamed of.

After the ratification of the treaty of peace between Mexico and the United States, our forces evacuated Mexico, and Captain Grant was sent to New York with his regiment, where its companies were detached and sent to the forts on the northern frontier. Grant and his company were first stationed at Detroit, and then transferred to Sacketts Harbor. In 1848 he was married to Miss Dent, in conformity with the engagement made five years before, to which both had religiously adhered.

The treaty of peace with Mexico had given us California, and coincident with the acquisition of the territory, gold was discovered there in such quantities as to attract an immense immigration, and it was necessary for the government to send out troops for the protection of the swarming hosts, both from themselves and from the Indians. The Fourth Infantry was sent to Oregon in 1851. The battalion in which Grant served was stationed at Fort Dallas, where the illustrious soldier obtained some further experience of Indian warfare.

He was separated from his family, and in this wild region shut out from any employment worthy his nature, and apparently from all hope of rising either as a citizen or a soldier. It would have been surprising if Grant had not been discontented. He was a man of deeds, emphatically a man of action; but there was nothing to be done worthy his ambition.
