the Bishop's Palace and the other outside fortifications on their
left. General Worth reached a defensible position just out of range of
the enemy's guns on the heights north-west of the city, and bivouacked
for the night. The engineer officers with him--Captain Sanders and
Lieutenant George G. Meade, afterwards the commander of the victorious
National army at the battle of Gettysburg--made a reconnoissance to the
Saltillo road under cover of night.

During the night of the 20th General Taylor had established a battery,
consisting of two twenty-four-pounder howitzers and a ten inch mortar,
at a point from which they could play upon Black Fort. A natural
depression in the plain, sufficiently deep to protect men standing in it
from the fire from the fort, was selected and the battery established on

judgment, and I mounted a horse and rode to the front to see what was
going on. I had been there but a short time when an order to charge was
given, and lacking the moral courage to return to camp--where I had been
ordered to stay--I charged with the regiment As soon as the troops were
out of the depression they came under the fire of Black Fort. As they
advanced they got under fire from batteries guarding the east, or lower,
end of the city, and of musketry. About one-third of the men engaged in
the charge were killed or wounded in the space of a few minutes. We
retreated to get out of fire, not backward, but eastward and
perpendicular to the direct road running into the city from Walnut
Springs. I was, I believe, the only person in the 4th infantry in the
charge who was on horseback. When we got to a lace of safety the
regiment halted and drew itself together--what was left of it. The
adjutant of the regiment, Lieutenant Hoskins, who was not in rob
