Blockading the Mouth of the Mississippi.

The first regularly commissioned man-of-war of the Confederate States was the "Sumter," an old passenger steamer remodelled so as to carry five guns. This vessel, though only registering five hundred tons, and smaller than many a steam-yacht of to-day, roamed over the high seas at will for more than a year, burning and destroying the merchant-vessels of the North, and avoiding easily any conflicts with the Northern men-of-war. Her exploits made the owners of American merchant-vessels tremble for their property; and the United States authorities made the most desperate attempts to capture her, but in vain. In his journal of Dec. 3, 1861, Capt. Semmes of the "Sumter" writes with the greatest satisfaction: "The enemy has done us the honor to send in pursuit of us the 'Powhattan,' the 'Niagara,' the 'Iroquois,' the 'Keystone State,' and the 'San Jacinto.'" Any one of these vessels could have blown the 'Sumter' out of water with one broadside, but the cunning and skill of her commander enabled her to escape them all.

It was on the 1st of June, 1861, that the "Sumter" cast loose from the levee at New Orleans, and started down the Mississippi on her way to the open sea. For two months workmen had been busy fitting her for the new part she was to play. The long rows of cabins on the upper deck were torn down; and a heavy eight-inch shell-gun, mounted on a pivot between the fore and mainmasts, and the grinning muzzles of four twenty-four-pounder howitzers peeping from the ports, told of her warlike character. The great levee of the Crescent City was crowded with people that day. Now and again the roll of the drum, or the stirring notes of "Dixie," would be heard, as some volunteer company marched down to the river to witness the departure of the entire Confederate navy. Slowly the vessel dropped down the river, and, rounding the English turn, boomed out with her great gun a parting salute to the city she was never more to see. Ten miles from the mouth of the river she stopped; for anchored off the bar below lay the powerful United States steamer "Brooklyn," with three other men-of-war, each more than a match for the infant navy of the Confederacy. Eleven days the "Sumter" lay tugging at her anchors in the muddy current of the great river, but at last the time of action arrived. The news came that the "Brooklyn" had started in chase of a vessel, and the mouth of the river was clear. Quickly the "Sumter" got under way, and with all steam up made for the channel over the bar. She was still six miles from the bar when the "Brooklyn" caught sight of her, and abandoning her first chase strove desperately to head her off. It was a time of intense excitement. Each vessel was about equally distant from the bar for which each was steaming at the highest possible speed. For the "Sumter," it was escape or die. It was too late to fly up the river to the sheltering guns of Fort St. Philip. Should the "Brooklyn" get within range, the "Sumter" was doomed. The "Brooklyn" was the faster vessel of the two, but had the wind in her teeth; while the "Sumter" had the advantage of wind and current. At length the pass was reached, and the "Sumter" dashed over the bar, and out on the smooth blue water of the Gulf of Mexico, well ahead of her powerful foe. The "Brooklyn" quickly rounded to, and a quick puff of smoke from amidships told the crew of the flying vessel that the terrible pivot-gun of their enemy had sent a warning message after them. But there was but a second of suspense, when a great jet of water springing from the surface of the gulf told that the bolt had fallen short. The "Brooklyn" then quickly crowded on all sail, and started in hot pursuit, but after four hours abandoned the chase, put up her helm, and started sullenly back for the river's mouth; while the tars of the "Sumter" crowded shrouds and bulwarks, and cheered heartily for the navy of the young Confederacy.

The "Sumter" was now fairly embarked on her career. The open sea was her territory, and all ships floating the stars and stripes at the masthead were to be her prey. She was not a strong vessel; and her orders were to avoid any battles with the powerful ships of the "Yankee" navy, but to seize and destroy all merchantmen that should come in her way. Her first purpose was to capture these vessels, and by selling them in neutral ports profit by the prize. But the neutral nations soon refused to admit all rebel prizes to their ports; and, as all the ports of the Confederacy were closed by the blockade, nothing was left but to burn the vessels when captured. Many a floating bonfire marked the way of the little "Sumter," and great was the consternation among the ship-owners of the North.

When four days out, the "Sumter" captured her first prize. She was a fine ship, the "Golden Rocket" of Maine, six hundred and ninety tons. With the United States flag fluttering at the peak, she came sailing proudly towards her unsuspected enemy, from whose peak the red flag of England was displayed as a snare. When the two vessels came within a mile of each other, the wondering crew of the merchantman saw the English flag come tumbling down, while a ball of bunting rose quickly to the peak of the mysterious stranger, and catching the breeze floated out, showing a strange flag,—the stars and bars of the Confederacy. At the same minute a puff of smoke from the "Long Tom" amidships was followed by a solid shot ricochetting along the water before the dismayed merchantman, and conveying a forcible, but not at all polite, invitation to stop. The situation dawned on the astonished skipper of the ship,—he was in the hands of "the Rebels;" and with a sigh he brought his vessel up into the wind, and awaited the outcome of the adventure. And bad enough the outcome was for him; for Capt. Semmes, unwilling to spare a crew to man the prize, determined to set her on fire. It was about sunset when the first boat put off from the "Sumter" to visit the captured ship. The two vessels were lying a hundred yards apart, rising and falling in unison on the slow rolling swells of the tropic seas. The day was bright and warm, and in the west the sun was slowly sinking to the meeting line of sky and ocean. All was quiet and peaceful, as only a summer afternoon in Southern seas can be. Yet in the midst of all that peace and quiet, a scene in the great drama of war was being enacted. Nature was peaceful, man violent.

For a time nothing was heard save the measured thump of the oars in the rowlocks, as the boats plied to and fro between the two ships, transporting the captured crew to the "Sumter." Finally the last trip was made, and the boat hoisted to the davits. Then all eyes were turned toward the "Golden Rocket." She lay almost motionless, a dark mass on the black ocean. The sun had long since sunk beneath the horizon; and the darkness of the night was only relieved by the brilliancy of the stars, which in those latitudes shine with wondrous brightness. Soon the watches on the "Sumter" caught a hasty breath. A faint gleam was seen about the companionway of the "Rocket." Another instant, and with a roar and crackle, a great mass of flame shot up from the hatch, as from the crater of a volcano. Instantly the well-tarred rigging caught, and the flame ran up the shrouds as a ladder of fire, and the whole ship was a towering mass of flame. The little band of men on the "Sumter" looked on the terrific scene with bated breath. Though they fully believed in the justice of their cause, they could not look on the destruction they had wrought without feelings of sadness. It was their first act of war. One of the officers of the "Sumter" writes: "Few, few on board can forget the spectacle,—a ship set fire to at sea. It would seem that man was almost warring with his Maker. Her helpless condition, the red flames licking the rigging as they climbed aloft, the sparks and pieces of burning rope taken off by the wind, and flying miles to leeward, the ghastly glare thrown upon the dark sea as far as the eye could reach, and then the deathlike stillness of the scene,—all these combined to place the "Golden Rocket" on the tablet of our memories forever." But it was not long before the crew of the "Sumter" could fire a vessel, and sail away indifferently, with hardly a glance at their terrible handiwork.

The "Sumter" continued on her cruise, with varying fortunes. Sometimes weeks would pass with no prizes to relieve the tedium of the long voyage. Occasionally she would run into a neutral port for coal or water, but most of the time was spent on the open sea. The crew were kept actively employed with drills and exercises; while the officers, yawning over their books or games, longed for the welcome cry from the masthead, "Sail ho!" In September the "Sumter" captured a brig, the "Joseph Park;" and the boarding officer, on examining the log-book, found an entry made by her captain on the day of leaving Pernambuco: "We have a tight, fast vessel, and we don't care for Jeff Davis." The unlucky captain had holloaed long before he was out of the wood.

The "Joseph Park" was the last prize the tars of the "Sumter" had the pleasure of "looting" for many days. Up and down the tropic seas the cruiser travelled, loitering about the paths of ocean commerce to no avail. Often enough the long-drawn hail of the lookout in the cross-trees, "Sail ho-o-o-o!" would bring the jackies tumbling up from the forecastle, and set the officers peering anxiously through their telescopes. But the sails so sighted proved to be English, French, Spanish, any thing but American; and life aboard the "Sumter" became as dull as a fisher's where fish are not to be found. In September Capt. Semmes ran his vessel into a Martinique harbor, to make some needed repairs, and give the sailors a run ashore. Here they were blockaded for some time by the United States frigate "Iroquois," but finally escaped through the cunning of Semmes. Lying in the harbor near the "Sumter" were two Yankee schooners, whose captains arranged with the commander of the "Iroquois" to signal him if the "Sumter" should leave the harbor. If on passing the bar she headed south, a single red light should gleam at the masthead of the schooner; should her course lie northward, two lights would be displayed. Semmes, lying at anchor in the bay, and chafing over his captivity, determined to break away. He had noticed the frequent communications between the schooners and the man-of-war, and suspected that his course would be spied out. Nevertheless, he determined to dare all, and one black night slipped his cables, and with all lights out, and running-gear muffled, glided swiftly out of the harbor. In the distance he could see the lights of the "Iroquois," as she steamed slowly up and down in the offing, like a sentry on guard. Up in the cross-trees of the "Sumter" sat a sharp-eyed old quarter-master, with orders not to mind the "Iroquois," but to keep a close watch on the suspected schooners. Soon a light gleamed from the maintop of each. Semmes's suspicions grew. "They have signalled our course," said he: "we'll double." The ship's head was quickly brought about, and headed south; then all turned to watch the movements of the "Iroquois." She had headed northward, and was exerting every power to catch the flying vessel supposed to be just ahead. Satisfied with having so successfully humbugged the enemy, the "Sumter" proceeded leisurely on her course to the southward, leaving the "Iroquois" steaming furiously in the opposite direction. "I do think, however," writes Capt Semmes in his log-book, "that a tough old quarter-master, and a grizzled boatswain's mate, who had clean shaven their heads in preparation for a desperate fight, were mightily disgusted."
