reinforcements towards the Bishop's Palace and the height which
commands it. To divert his attention as far as practicable, the
first division, under Brigadier-General Twiggs, and the field
division of volunteers, under Major-General Butler, were
displayed in front of the town until dark. Arrangements were made
at the same time to place in battery during the night, at a
suitable distance from the enemy's main work, the citadel, two
twenty-four pounder howitzers, and a ten-inch mortar, with a view
to open a fire on the following day, when I proposed to make a
diversion in favor of General Worth's movement. The 4th Infantry
covered this battery during the night. General Worth had, in the
mean time, reached and occupied for the night a defensive
position just without range of a battery above the Bishop's
Palace, having made a reconnoissance as far as the Saltillo road.

Before proceeding to report the operations of the 21st and
following days, I beg leave to state that I shall mention in
detail only those which were conducted against the eastern
extremity of the city, or elsewhere, under my immediate

against the centre and left of the town, to favor his enterprise
against the heights in rear. The infantry and artillery of the
first division, and the field division of volunteers, were
ordered under arms and took the direction of the city, leaving
one company of each regiment as a camp guard. The 2d Dragoons,
under Lieutenant-Colonel May, and Colonel Wood's regiment of
Texas mounted volunteers, under the immediate direction of
General Henderson, were directed to the right to support General
Worth, if necessary, and to make an impression, if practicable,
upon the upper quarter of the city. Upon approaching the mortar
battery, the 1st and 3d regiments of infantry and battalion of
Baltimore and Washington volunteers, with Captain Bragg's field
battery, the whole under the command of Lieutenant-Colonel
Garland, were directed toward the lower p
