acting against Belen. General Worth commanded the column against San
Cosme. When Chapultepec fell the advance commenced along the two
aqueduct roads. I was on the road to San Cosme, and witnessed most that
took place on that route. When opposition was encountered our troops
sheltered themselves by keeping under the arches supporting the
aqueduct, advancing an arch at a time. We encountered no serious
obstruction until within gun-shot of the point where the road we were on
intersects that running east to the city, the point where the aqueduct
turns at a right angle. I have described the defences of this position
before. There were but three commissioned officers besides myself, that
I can now call to mind, with the advance when the above position was
reached. One of these officers was a Lieutenant Semmes, of the Marine
Corps. I think Captain Gore, and Lieutenant Judah, of the 4th infantry,
were the others. Our progress was stopped for the time by the single
piece of artillery at the angle of the roads and the infantry occupying
the house-tops back from it.

West of the road from where we were, stood a house occupying the
south-west angle made by the San Cosme road and the road we were moving
upon. A stone wall ran from the house along each of these roads for a
considerable distance and thence back until it joined, enclosing quite a
yard about the house. I watched my opportunity and skipped across the
road and behind the south wall. Proceeding cautiously to the west
corner of the enclosure, I peeped around and seeing nobody, continued,
still cautiously, until the road running east and west was reached. I
then returned to the troops, and called for volunteers. All that were
close to me, or that heard me, about a dozen, offered their services.
Commanding them to carry their arms at a trail, I watched our
opportunity and got them across the road and under cover of the wall
beyond, before the enemy had a shot at us. Our men under cover of the
arches kept a close watch on the intrenchments that crossed our path and
the house-tops beyond, and whenever a head showed itself above the
parapets they would fire at it. Our crossing was thus made practicable
without loss.

When we reached a safe position I instructed my little command again to
carry their arms at a trail, not to fire at the enemy until they were
ordered, and to move very cautiously following me until the San Cosme
road was reached; we would then be on t
