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 consequently started which was exploded on the 1st of July, destroying an entire rebel redan, killing and wounding a considerable number of its occupants and leaving an immense chasm where it stood. No attempt to charge was made this time, the experience of the 25th admonishing us. Our loss in the first affair was about thirty killed and wounded. The enemy must have lost more in the two explosions than we did in the first. We lost none in the second.
