Grant says, "I was with the earliest of the troops to enter the mills. In passing through to the north side, looking toward Chepultepec, I happened to notice that there were armed Mexicans still on top of the building, only a few feet from many of our men. Not seeing any stairway or ladder reaching to the top of the building, I took a few soldiers, and had a cart that happened to be standing near brought up, and, placing the shafts against the wall, and chocking the wheels so that the cart could not back, used the shafts as a sort of ladder, extending to within three or four feet of the top. By this I climbed to the roof of the building, followed by a few men, but found a private soldier had preceded me by some other way. There were still quite a number of Mexicans on the roof, among them a major and five or six officers of lower grades, who had not succeeded in getting away before our troops occupied the building. They still had their arms, while the soldier before mentioned was walking as sentry, guarding the prisoners he had _surrounded_, all by himself. I halted the sentinel, received the swords from the commissioned officers, and proceeded, with the assistance of the soldiers now with me, to disable the muskets by striking them against the edge of the wall, and throwing them to the ground below." Five days after the fall of Molino, Chepultepec was taken, with severe loss. Grant was mentioned in the official report as having "behaved with distinguished gallantry." Just before the City of Mexico fell into our hands, Grant was made first lieutenant. Promotion had not come rapidly. It is sometimes better if success does not come to us early in life. To learn how to work steadily, day after day, with an unalterable purpose; to learn how to concentrate thought and will-power, how to conquer self through failure and hope deferred, is often essential for him who is to govern either by physical or moral power. After Mexico fell, and General Scott lived in the halls of the Montezumas, he controlled the city as a Havelock or a Gordon might have done; and Grant learned by observation the best of all lessons for a soldier, to be magnanimous to a fallen foe. He learned other valuable lessons in this war; made the acquaintance of the officers with whom he was to measure his strength, in the most stupendous war of modern times, twenty years later. When the treaty of peace was signed between our country and Mexico, February 2, 1848, whereby we paid fifteen million dollars for the territory ceded to us, Grant obtained leave of absence for four months. One person must have been inexpressibly thankful that his life had been spared. Four years, and she had seen him but once! How noble we often become by the mellowing power of circumstances which prevent our having our own way! Discipline may be only another word for achievement.
