r men, catching them in their hands, returned
them.

Our mine had been started some distance back down the hill; consequently
when it had extended as far as the parapet it was many feet below it.
This caused the failure of the enemy in his search to find and destroy
it. On the 25th of June at three o'clock, all being ready, the mine was
exploded. A heavy artillery fire all along the line had been ordered to
open with the explosion. The effect was to blow the top of the hill off
and make a crater where it stood. The breach was not sufficient to
enable us to pass a column of attack through. In fact, the enemy having
failed to reach our mine had thrown up a line farther back, where most
of the men guarding that point were placed. There were a few men,
however, left at the advance line, and others working in the
countermine, which was still being pushed to find ours. All that were
there were thrown into the air, some of them coming down on our side,
still alive. I remember one colored man, who had been under ground at
work when the explosion took place, who was thrown to our side. He was
not much hurt, but terribly frightened. Some one asked him how high he
had gone up. "Dun no, massa, but t'ink 'bout t'ree mile," was his
reply. General Logan commanded at this point and took this colored man
to his quarters, where he did service to the end of the siege.

As soon as the explosion took place the crater was seized by two
regiments of our troops who were near by, under cover, where they had
been placed for the express purpose. The enemy made a desperate effort
to expel them, but failed, and soon retired behind the new line. From
here, however, they threw hand-grenades, which did some execution. The
compliment was returned by our men, but not with so much effect. The
enemy could lay their grenades on the parapet, which alone divided the
contestants, and roll them down upon us; while from our side they had to
be thrown over the parapet, which was at considerable elevation. During
the night we made efforts to secure our position in the crater against
the missiles of the enemy, so as to run trenches along the outer base of
their parapet, right and left; but the enemy continued throwing their
grenades, and brought boxes of field ammunition (shells), the fuses of
which they would light with portfires, and throw them by hand into our
ranks. We found it impossible to continue this work. Another mine was
