CHAPTER XIV.

RETURN OF THE ARMY--MARRIAGE--ORDERED TO THE PACIFIC COAST--CROSSING THE
ISTHMUS--ARRIVAL AT SAN FRANCISCO.

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 w
