fects of his delusion.

The first step in the new movement was to carry Chapultepec, a
natural and isolated mound of great elevation, strongly fortified
at its base, on its acclivities and heights. Besides a numerous
garrison, here was the military college of the republic, with a
large number of sub-lieutenants and other students. Those works
were within direct gun-shot of the village of Tacubaya, and,
until carried, we could not approach the city on the west without
making a circuit too wide and too hazardous.

In the course of the same night (that of the 11th) heavy
batteries, within easy ranges, were established. No. 1, on our
right, under the command of Captain Drum, 4th Artillery (relieved
late next day, for some hours, by Lieutenant Andrews, of the 3d),
and No. 2, commanded by Lieutenant Hagner, Ordnance, both
supported by Pillow's division, were commanded, the former, by
Captain Brooks and Lieutenant S. S. Anderson, 2d Artillery,
alternately, and the latter by Lieutenant Stone, Ordnance. The
batteries were traced by Captain Huger and Captain Lee, Engineer,
and constructed by them with the able assistance of the young
officers of those corps and the Artillery.

To prepare for an assault, it was foreseen that the play of the
batteries might run into the second day; but recent captures had
not only trebled our siege-pieces, but also our ammunition; and
we knew that we should greatly augment both by carrying the
place. I was, therefore, in no haste in ordering an assault
before the works were well crippled by our missiles.

The bombardment and cannonade, under the direction of Captain
Huger, were commenced early in the morning of the 12th. Before
nightfall, which necessarily stopped our batteries, we had
perceived that a good impression had been made on the castle and
its outworks, and that a large body of the enemy had remained
outside, towards the city, from an early hour to avoid our (p. 327)
fire, and to be at hand on its cessation, in order to
re-enforce the garrison against an assault. The same outside
force was discovered the next morning, after our batteries had
re-opened upon the castle, by which we again reduced its garrison
to the minimum needed for the guns.

Pillow and Quitman had been in position since early in th
