Personal Memoirs of U. S. Grant, Part 2.

My experience in the Mexican war was of great advantage to me afterwards. Besides the many practical lessons it taught, the war brought nearly all the officers of the regular army together so as to make them personally acquainted. It also brought them in contact with volunteers, many of whom served in the war of the rebellion afterwards. Then, in my particular case, I had been at West Point at about the right time to meet most of the graduates who were of a suitable age at the breaking out of the rebellion to be trusted with large commands. Graduating in 1843, I was at the military academy from one to four years with all cadets who graduated between 1840 and 1846—seven classes. These classes embraced more than fifty officers who afterwards became generals on one side or the other in the rebellion, many of them holding high commands. All the older officers, who became conspicuous in the rebellion, I had also served with and known in Mexico: Lee, J. E. Johnston, A. S. Johnston, Holmes, Hebert and a number of others on the Confederate side; McCall, Mansfield, Phil. Kearney and others on the National side. The acquaintance thus formed was of immense service to me in the war of the rebellion—I mean what I learned of the characters of those to whom I was afterwards opposed. I do not pretend to say that all movements, or even many of them, were made with special reference to the characteristics of the commander against whom they were directed. But my appreciation of my enemies was certainly affected by this knowledge. The natural disposition of most people is to clothe a commander of a large army whom they do not know, with almost superhuman abilities. A large part of the National army, for instance, and most of the press of the country, clothed General Lee with just such qualities, but I had known him personally, and knew that he was mortal; and it was just as well that I felt this.
The treaty of peace was at last ratified, and the evacuation of Mexico by United States troops was ordered. Early in June the troops in the City of Mexico began to move out. Many of them, including the brigade to which I belonged, were assembled at Jalapa, above the vomito, to await the arrival of transports at Vera Cruz: but with all this precaution my regiment and others were in camp on the sand beach in a July sun, for about a week before embarking, while the fever raged with great virulence in Vera Cruz, not two miles away. I can call to mind only one person, an officer, who died of the disease. My regiment was sent to Pascagoula, Mississippi, to spend the summer. As soon as it was settled in camp I obtained a leave of absence for four months and proceeded to St. Louis. On the 22d of August, 1848, I was married to Miss Julia Dent, the lady of whom I have before spoken. We visited my parents and relations in Ohio, and, at the end of my leave, proceeded to my post at Sackett's Harbor, New York. In April following I was ordered to Detroit, Michigan, where two years were spent with but few important incidents.
