Captain Horace Brooks, of the artillery, acting as infantry. I
explained to Brooks briefly what I had discovered and what I was about
to do. He said, as I knew the ground and he did not, I might go on and
he would follow. As soon as we got on the road leading to the city the
troops serving the gun on the parapet retreated, and those on the
house-tops near by followed; our men went after them in such close
pursuit--the troops we had left under the arches joining--that a second
line across the road, about half-way between the first and the garita,
was carried. No reinforcements had yet come up except Brooks's company,
and the position we had taken was too advanced to be held by so small a
force. It was given up, but retaken later in the day, with some loss.

Worth's command gradually advanced to the front now open to it. Later
in the day in reconnoitring I found a church off to the south of the
road, which looked to me as if the belfry would command the ground back
of the garita San Cosme. I got an officer of the voltigeurs, with a
mountain howitzer and men to work it, to go with me. The road being in
possession of the enemy, we had to take the field to the south to reach
the church. This took us over several ditches breast deep in water and
grown up with water plants. These ditches, however, were not over eight
or ten feet in width. The howitzer was taken to pieces and carried by
the men to its destination. When I knocked for admission a priest came
to the door who, while extremely polite, declined to admit us. With the
little Spanish then at my command, I explained to him that he might save
property by opening the door, and he certainly would save himself from
becoming a prisoner, for a time at least; and besides, I intended to go
in whether he consented or not. He began to see his duty in the same
light that I did, and opened the door, though he did not look as if it
gave him special pleasure to do so. The gun was carried to the belfry
and put together. We were not more than two or three hundred yards from
