howed plainly that they did
not enjoy the sight. We moved out at once, and found them gone from our
immediate front. Clarke's brigade of Worth's division now moved west
over the point of the Pedregal, and after having passed to the north
sufficiently to clear San Antonio, turned east and got on the causeway
leading to Churubusco and the City of Mexico. When he approached
Churubusco his left, under Colonel Hoffman, attacked a tete-de-pont at
that place and brought on an engagement. About an hour after, Garland
was ordered to advance directly along the causeway, and got up in time
to take part in the engagement. San Antonio was found evacuated, the
evacuation having probably taken place immediately upon the enemy seeing
the stars and stripes waving over Contreras.
The troops that had been engaged at Contreras, and even then on their
way to that battle-field, were moved by a causeway west of, and parallel
to the one by way of San Antonio and Churubusco. It was expected by the
commanding general that these troops would move north sufficiently far
to flank the enemy out of his position at Churubusco, before turning
east to reach the San Antonio road, but they did not succeed in this,
and Churubusco proved to be about the severest battle fought in the
valley of Mexico. General Scott coming upon the battle-field about this
juncture, ordered two brigades, under Shields, to move north and turn
the right of the enemy. This Shields did, but not without hard fighting
and heavy loss. The enemy finally gave way, leaving in our hands
prisoners, artillery and small arms. The balance of the causeway held
by the enemy, up to the very gates of the city, fell in like manner. I
recollect at this place that some of the gunners who had stood their
ground, were deserters from General Taylor's army on the Rio Grande.
Both the strategy and tactics displayed by General Scott in these
various engagements of the 20th of August, 1847, were faultless as I
look upon them now, after the lapse of so many years. As before stated,
the work of the engineer officers who made the reconnoissances and led
the different commands to their destinations, was so perfect that the
chief was able to give his orders to his various subordinates with all
the precision he could use on an ordinary march. I mean, up to the
points from which the attack was to commence. After that point is
reached the enemy often induces a change of orders not before
