The earliest efforts of the Federal Government to shut the Confederates in had been directed toward the closing of the port of Charleston. There first a blockading fleet had been established, and when it proved ineffective an effort had been made very early in the war to close the port by sinking hulks, loaded with stone in the main channels, leading into that harbor. Fortunately for all concerned, this effort permanently to close a commercial port failed completely and conspicuously. So far from obstructing the entrance to the harbor, the sinking of the hulks there had the effect of extensive dredging. The tide flows in and out of the port with a tremendous current which brooks no resistance. When the stone laden hulks were sunk this current quickly swept away the sand and mud from beneath them, so that presently the harbor entrance was found to have been actually deepened by the effort to close it.
From that time forward two objects engaged Federal attention so far as Charleston was concerned; one of these was to maintain in front of the harbor a blockading squadron strong enough to prevent the entrance and exit of ships. The other was to force the harbor itself, capture its defenses and recover the city to Federal possession. In both of these efforts the Federal operations failed, but in their progress they involved some of the severest and most picturesque battling of the war.
The profits of blockade running were so great that English capitalists invested lavish sums in the business as a promising speculation. They built ships of light draft, great power, and a speed greater than that of any vessel in the American navy for the express purpose of carrying on this forbidden traffic. These ships had but little free-board exposed above the water. They were painted a dull sage green, as nearly as possible the color of the sea itself, when looked at from a distance. They were commanded by daring navigators and manned by equally daring crews who stood ready to take any and every risk that might aid in the achievement of ends so profitable as those aimed at in this commerce.
And those profits were tempting in an extraordinary degree. With cotton purchasable in the South for a few cents per pound, payable in the enormously depreciated Confederate currency, and salable in England at almost incredibly high prices in gold, and with all forms of English-made goods bearing fabulous prices in the South, it was easily calculable that if a ship could complete one round trip from Nassau to Charleston and back again and then should be lost with all its cargo on a second attempt, there would still remain to the owners a profit of not less than a hundred per cent upon the money invested.
As a matter of fact the steamer Minho, and several others of the blockade runners continued until late in the war to make their trips successfully, almost with the regularity of packet boats. They carried into Charleston stores of quinine, opium and other drugs which the Confederate Government stood ready to buy at fabulous prices. They carried clothing also, and shoes and harness, all of which were eagerly purchased at any price that the importers might choose to charge. They carried out of Charleston the cotton to which the markets of the world were otherwise closed, and which could be purchased, therefore, at a price so low as to make its cost an inconsiderable fraction unworthy of consideration. So the blockade running went on.
So far as the reduction of the city and its defenses was concerned the failure of Federal efforts was still more pronounced. Great sums were expended, vast quantities of ammunition were wasted, and many lives were sacrificed in an effort—futile from beginning to end—to reduce this stronghold. Charleston, the birthplace of Secession and of the Confederate war remained in Confederate possession until the very end. The city did not fall under Federal control until those closing days of the war when Sherman, after his march to the sea, began his final movement northward in rear of the Carolina port.
In the meanwhile the struggle at that point was marked by many fierce land contests in the country round about, and by much heroic naval fighting.
The Confederates made such endeavors as they could, with the meager means at hand, to create a naval power there which might be launched against the blockading fleet outside. There was no navy yard and no ship-building plant at Charleston, but with an energy that did credit to the men who exercised it, several small gunboats and torpedo boats were extemporized within the harbor and employed with energy and effect. In January, 1863, two of these extemporized gunboats boldly steamed out one morning, and assailed the Federal fleet lying off the harbor. They promptly disabled two of the Federal ships, and compelled them to strike their colors. But the rest of the enormous Federal fleet came quickly to the rescue and the two little gunboats were forced to retreat again, and take refuge under the guns of the forts.
This event gave warning at Washington of the necessity of promptly and greatly strengthening the naval force employed off Charleston. Accordingly, a powerful fleet, consisting of seven monitors, an ironclad frigate, an ironclad ram and many gunboats was sent in April, 1863, under command of Rear-Admiral S. F. Du Pont, to reduce and capture Charleston. The expedition failed in its purpose, as all previous ones sent with a like end in view had done, and as all future ones did to the very end.
It was on the seventh of April, 1863, that Du Pont, with his masterful armada, steamed into the harbor to reduce the forts and to sweep away all the defenses of Charleston. At every point he found himself under a destructive fire from forts and batteries occupied by men who knew how to shoot. At every point he found his pathway obstructed by chains and torpedoes and whatever else mechanical ingenuity up to that period in human history had succeeded in devising for the checking of an enemy's progress.
