llow were to march to Tacubaya, where
they awaited further orders.

The attack was begun by the batteries of Drum and Peter Valentine
Hagner, and the fire proved to be well directed. The guns at the
castle answered promptly and kept up a vigorous cannonade. When there
was some cessation of firing from the castle, Captain Lee, under
direction of General Scott, using the wall of the aqueduct as a
parapet, placed two pieces of artillery under Captain Horace Brooks,
which opened fire. Steptoe's battery kept up a continuous firing.
Santa Anna, who was deceived at the point of attack, on hearing the
guns of Steptoe, moved at once to Candelaria and San Antonio Garita,
where he expected the attack. At noon he repaired to Chapultepec, and,
taking charge of a battalion, moved to re-enforce a work which was
being attacked. The Americans opened fire on this force and compelled
it to withdraw. General Bravo, expecting an assault, asked for
re-enforcements, which General Santa Anna promised should be furnished
in time. In the meantime the Governor of the State of Mexico had
arrived with seven hundred men, having reached a point near Tacubaya
on the 11th, and his arrival greatly increased the Mexicans' hopes.
Not being joined by cavalry as he expected, the Governor remained
inactive on the 11th, 12th, and 13th. Quitman's division, with United
States Marines and a company of New York volunteers, remained in the
rear near the Tacubaya road during the 12th.

It was now determined by General Scott to resume the bombardment early
next morning, and to attack with the columns under Quitman and Pillow.
In aid of this a storming party was detailed from Worth's division of
ten officers and two hundred and sixty men, under command of Captain
Samuel McKenzie, Second Artillery, and a like detail from Twiggs's
division under Captain Silas Casey, Second Infantry, in support of
Pillow's movement, and General P.F. Smith's brigade of Twiggs's
division was ordered to the support of Quitman. The bombardment was
renewed early on the morning of the 13th. Four companies of the
voltigeur regiment, under Lieutenant-Colonel Joseph E. Johnston, were
instructed, on the cessation of firing, to move rapidly under cover of
the wall and enter the inclosure at its opening. Four companies under
Colonel Timothy P. Andrews were ordered to unite with Johnston, deploy
as skirmishers, and drive the enemy from his shelter. McKenzie was
ordered to move in the rear of Johns
