Gen. McPherson has blown a hole in the enemy’s defenses and is attempting to exploit the opening. I sent word to Gen. Ord,
NEAR Vicksburg, June 25, 1863.
McPherson secured the crater made by the explosion. The cavity made was sufficiently large to shelter two regiments. The enemy made an effort to drive our troops away. Our loss about 30 killed and wounded, some ten of them officers, and 3 field officers. Guns will be in the crater by morning, with rifle-pits to the left to defend it. If we can hold the position until morning it will evidently give us possession of a long line of rifle-pits to the right, and a fair way of advancing to enfilade to the left.
