utenant-Colonel Plympton respectively, vigorously engaged the
right of the work and part of its rear. At the moment the Rifles,
belonging to Smith's, were detached in support of
Brigadier-General Shields on our extreme left, and the 4th
Artillery, acting as infantry, under Major Gardner, belonging to
Riley's brigade, had been left in charge of the camp, trophies,
etc., at Contreras. Twiggs' division at Churubusco had thus been
deprived of the services of two of its most gallant and effective
regiments.

The immediate results of this victory were: the capture of seven
field pieces, some ammunition, one color, three generals, and one
thousand two hundred and sixty-one prisoners, including other
officers.

Captains E. A. Capron and M. J. Burke, and Lieutenant G. Hoffman,
all of the 1st Artillery, and Captain J. W. Anderson and
Lieutenant Thomas Easley, both of the 2d Infantry, five officers
of great merit, fell gallantly before this work.

The capture of the enemy's citadel was the _fourth_ great
achievement of our arms in the same day.

It has been stated that some two hours and a half before,
Pierce's, followed closely by the volunteer brigade, both under
the command of Brigadier-General Shields, had been dispatched to
our left to turn the enemy's works; to prevent the escape of the
garrisons and to oppose the extention of the enemy's numerous
corps from the rear upon and around our left.

Considering the inferior numbers of the two brigades, the objects
of the movement were difficult to accomplish. Hence the
re-enforcement (the Rifles, etc.,) sent forward a little later.

In a winding march of a mile around to the right, this temporary
division found itself on the edge of an open wet meadow, near the
road from San Antonio to the capital, and in the presence of some
four thousand of the enemy's infantry, a little in rear of
Churubusco, on that road. Establishing the right at a strong
building, Shields extended his left parallel to the road, to
outflank the enemy toward the capital. But the enemy extending
his right, supported by three thousand cavalry, more rapidly
(being favored by better ground) in the same direction, Shields
concentrated the division about a hamlet and determined to attack
in front. The battle was long, hot
