Raphael Semmes, Memoirs of Service Afloat During the War Between the States

[208] a ship's bottom, with a cone, which it has brought near the surface, from surrounding deep waters. As it is constantly at work, the bottom of the sea is constantly changing, and hence, on coral coasts, surveying steamers should be almost always at work. Having anchored in the open sea, and the sea being a little rough, we found, when we came to heave up our anchor, the next morning, that we brought up only the ring, and a small piece of the shank. It had probably been caught in the rocky bottom, and broken by the force of the windlass, aided by the pitching of the ship.

There was, much to my regret, no pilot-boat in sight. The entrance to Maranham is quite difficult, but difficult as it was, I was forced to attempt it. We rounded safely, the shoals of Mount Itacolomi, and passed the middle ground of the Meio, and I was already congratulating myself that the danger was past, when the ship ran plump upon a sand-bank, and stopped! She went on, at full speed, and the shock, to those standing on deck, was almost sufficient to throw them off their feet. We had a skilful leadsman in the chains, and at his last cast, he had found no bottom, with eight fathoms of line—all that the speed of the ship would allow him to sink. Here was a catastrophe! Were the bones of the Sumter to be laid to rest, on the coast of Brazil, and her Commander, and crew to return to the Confederate States, and report to the Government, that they had lost its only ship of war! This idea flashed through my mind for an instant, but only for an instant, for the work of the moment pressed. The engineer on duty had stopped his engine, without waiting for orders, as soon as he felt the ship strike, and I now ordered it reversed. In a moment more the screw was revolving in the opposite direction, and the strong tide, which was running out, catching the ship, on the port bow, at the same time, she swung round to starboard, and slid off the almost perpendicular edge of the bank into deep water, pretty much as a turtle will drop off a log. The first thing I did was to draw a long breath, and the second was to put on an air of indifference, as if nothing had happened, and tell the officer of the deck, in the coolest manner possible, to ‘let her go ahead.’ We now proceeded more cautiously, under low steam, giving the leadsman plenty of time to get his soundings,
