Statistics for occurrence #1 of “General Grant” in chapter 57 of Admiral David D. Porter, The Naval History of the Civil War.:
... four heavy iron-clads in utter uselessness.

In consequence, General Grant ordered the channel to be still further obstructed with stones, so that no vessel can pass.
We can hold the fort with a very small force and prevent any one from removing the obstructions.
