e have now reached the period at which the rapid decline in the prospects of the Confederacy had become apparent, not only to its enemies, but to its friends. Throughout the South the stars and bars floated over only three strongholds of any importance,—Charleston, Mobile, and Wilmington. One after the other these were destined to fall, and their final overthrow was to be the work of the navy. It was no easy task in any one of the three instances to dislodge the Confederates from their positions; for though beaten in the Middle States, driven from the Mississippi, and with their very citadel at Vicksburg in the hands of the Federals, they still fought with a courage and desperation that for a long time baffled the attacks of the Unionists.
From the very opening of the war, Charleston Harbor had been the scene of naval hostilities. The Confederates, looking upon their mouldering wharves, and vessels tugging idly at their chains, then looking out to sea past Fort Sumter, could see the ships of the blockading-squadron maintaining the watchful guard that was slowly reducing the city to penury. What wonder that the blood of the good people of Charleston boiled, and that they built, and hurled against their hated enemy, weird naval monsters, shapeless torpedo-boats running beneath the water, or huge rams that might even batter in the heavy walls of Fort Sumter!
One attack so made was successful to a certain extent. It was in February, 1864, that an inventive genius in the beleaguered city brought out a steam torpedo-boat. The craft was about twenty-five feet long, shaped like a cigar, built of boiler iron, and propelled by a screw. She had no smokestack, and her deck barely rose above the surface of the water. Running out from her bow was a stout spar fifteen feet long, bearing at its end a huge torpedo charged with two hundred pounds of powder. Just before nine o'clock one night, the lookout on the deck of the frigate "Housatonic" saw this strange object approaching the ship. It was a bright night, with no sea on. As yet torpedoes were hardly known, so the lookout took it for a large fish, and simply watched with interest its playful movements. Not until it came so close that no guns could be brought to bear, did any suspicion of danger enter the lookout's mind. Then there was the roll of the alarm-drums; while the men rushed to the side, and poured a fierce fire from small-arms on the mysterious object. The "Housatonic" started her engines, and tried to escape; but, before any headway could be gained, the launch dashed alongside, and a slight jar was felt. Then, with a tremendous roar, a huge column of water was thrown high in air, washing away men and boats from the deck of the warship. A hole large enough to drive a horse through was rent in the hull of the ship. Great beams were broken in twain, the heaviest guns were dismounted, and men were hurled fifty feet into the air. In five minutes the ship had gone to the bottom, and boats from other vessels were picking up the crew. The launch escaped in the excitement.
The Union sailor-boys did not let the Confederates outdo them in dash and pluck. One of the cleverest bits of work in the whole war was done by four boat-crews from two men-of-war on the Charleston station. Word had been brought to the blockaders, that, far up a little deep and narrow creek, a large steamship was loading with cotton, expecting to reach the ocean through the labyrinth of inlets that fairly honeycomb the South Carolina coast. Should she once get into that network of waterways, it would require a whole fleet to catch her; for there was no telling at what point she might emerge.
It was at once determined to try to capture her as she lay at her deck, and four boats' crews of picked men were sent out on the expedition. It was early evening when they set out; and all through the dark night they pulled away, threading the mazes of the tidal inlets. Just as the eastern horizon was beginning to grow gray with the coming dawn, they came in sight of their destination. Sure enough, there on the bank of the river was a little Southern village, changed into a prosperous town by the blockade-runners that had evidently been making this place a harbor for some time.
All was dark and silent as the grave. Confident in their fancied security, the blockade-runners had all turned in, leaving no one on guard. The steamer was loaded, and ready to sail in the morning; and the thin wreaths of smoke rising from her smokestack told that the fires were up. Stealthily the sailors pulled alongside, and clambered on deck. Without a word they stole below, put the crew under guards, and rushed into the engine-room, where they found the engineer dozing on his stool. He was ordered to get under way at once; and, though he looked rather dazed, he obeyed the order. And in fifteen minutes the steamer was speeding down-stream, leaving the old town still asleep.
One man alone of all the townspeople had seen the capture. A negro, hiding behind a pile of lumber on the dock, had watched the whole affair, and, as if struck dumb with astonishment, failed to give the alarm until the steamer was out of sight down the winding stream. The blue-jackets took their capture safely out of the enemy's lines, and the next day it was sent to New York as a prize.
While the navy was keeping the port of Charleston sealed, and every now and then beating back the improvised gunboats that the Confederates sent out in the forlorn hope of breaking through the blockade, the armies of the North were closing in upon the doomed city. All the North cried aloud for the capture of Charleston. It was the city which fired the first gun of the war. Let it be reduced! On every available point of land a Union battery was built. Far out in the swamps back of the city, where it was thought no living thing save reptiles could exist, the soldiers of the North had raised a battery, mounting one two-hundred-pound gun. When a young lieutenant was ordered to build this battery, he looked the ground over, and reported the thing impossible. "There is no such word as impossible," sternly answered the colonel. "Set to work, and call for whatever you need to secure success."
