In referring to this incident, the Admiral said:

"A good Providence, which directs the most important events, sent the
battery off toward Fort St. Philip, and, as it came abreast of that
formidable fort, it blew up with a force which scattered the fragments

the smoke cleared off it was nowhere to be seen, having sunk immediately
in the deep water of the Mississippi. The explosion was terrific and was
seen and heard for many miles up and down the river. Had it occurred
near the vessels, it would have destroyed every one of them."

killed and wounded. The capture of that last Confederate stronghold on
the Mississippi was a severe and tedious task, but General Grant, with
that bulldog tenacity for which he was famous, held on until the 4th
