The Naval History of the United States. Volume 2

All imaginable plans were tried to get the army below the city; for Grant's command had come down from Cairo, and were at the northern and most impregnable side of the enemy's works. As at Island No. 10, a sharp bend in the river made a long peninsula right under the Confederates' guns. Grant, remembering the plan adopted before, set to work to cut a canal through the peninsula, so that the gunboats and transports might get below the forts. Twelve hundred negroes worked with a will upon this ditch for weeks. Then came a terrible rain-storm: the swollen, muddy torrent of the river broke in upon the unfinished canal, and that work was wasted. Then a new plan was suggested, this time by Commodore David Porter, who all through the war showed the greatest delight in taking his big gunboats into ditches where nothing larger than a frog or musk-rat could hope to navigate, and then bringing them out again safe after all.

The country back of Vicksburg was fairly honeycombed with shallow lakes, creeks, and those sluggish black streams called in the South bayous. Porter had been looking over this aqueous territory for some time, and had sent one of his lieutenants off in a steam-launch to see what could be done in that network of ditches. When the explorer returned, he brought cheering news. He was confident that, with tugs and gangs of axemen clearing the way, the gunboats could be taken up the Yazoo River, then into a wide bayou, and finally through a maze of small waterways, until they should reach the Mississippi again below the Vicksburg batteries. Then the transports could follow, the troops could march down the other side of the river, be met by the transports, ferried across, and take Vicksburg on the flank. It was a beautiful plan; and Porter went to Grant with it, full of enthusiasm.

Gen. Grant considered the matter for some time, but finally gave his consent, and detailed a number of blue-coated soldiers to aid Porter's blue-jackets in the work. They first cut the levees, and let the mighty tide of the Mississippi sweep in, filling the bayous to the brim, and flooding all the country round about. Then the gunboats plunged in, and were borne along on the rushing tide until they brought up, all standing, against the trunks of trees, or had their smoke-stacks caught by overhanging branches.

Then came the tug of war; and the axemen were called to the front, and set to work. They chopped their way along for some distance; the rapid current from the river banging the vessels against the trees and stumps, until all the standing rigging and light cabins were swept away. After a good deal of work they saw before them a broad river, wide enough for two vessels to steam abreast. Soon they drifted out into it, and the commanding officer sang out cheerily, "On to Vicksburg, boys, and no more trees to saw." And so they steamed on, thinking how neatly they should take the "gray-coats" in the rear, when suddenly a bend in the river showed them, just ahead, a fort in the middle of the river, with the channel blocked on either side. That was a surprise. The works were new, and the water was still muddy about the sunken steamers. Clearly the wily Pemberton had heard of this inland naval expedition, and was determined to check it effectually.

The gunboats backed water, and crowded in confused groups. The gunners in the fort took hurried aim, and pulled the lanyards of their cannon, forgetting that those pieces were not loaded. It was hard to tell which party was the more excited at the unexpected meeting. This gave the blue-jackets a chance to collect their thoughts, and in a minute or two the gunboats opened fire; but they were soon convinced that the fort was too much for them, and they turned and crawled back through the woods to the fleet above Vicksburg. Pemberton scored one point for successful strategy.

But, even while this expedition was working its way back to the station of the vessels on the Mississippi, Porter was starting another through a second chain of water-courses that he had discovered. This time he was so sure of getting into the rear of Vicksburg, that he took four of his big iron-clads, and two light mortar-boats built especially for work in the woods. Gen. Sherman, with a strong army-force, marched overland, keeping up with the gunboats. Admiral Porter, in his Memoirs, gives a graphic picture of this expedition. Back of Vicksburg the country is low, and intersected in every direction by narrow, tortuous bayous, lined on either side by gloomy morasses or majestic forests. Into these little-known water-courses Porter boldly led his ponderous iron-clads; while Sherman, with a detachment of troops, advanced along the shore, keeping as near the flotilla as possible. Seldom have naval vessels been detailed upon so strange a service. For days they steamed on under the spreading branches of trees, that often spanned the bayous in a mighty arch overhead, shutting out all sunlight. For a time this navigation of placid, shady waterways was pleasant enough; but, as they penetrated farther into the interior, the jackies sighed for the blue waters of the ocean, or even for the turbid current of the Mississippi. The heavy foliage that gave so grateful a shade also harbored all sorts of animals; and coons, rats, mice, and wildcats, that had been driven to the trees for shelter during the prevailing high water, peered down upon the sailors, and often dropped sociably down upon the decks of the vessels gliding beneath.

At some portions of the voyage the flotilla seemed to be steaming through the primeval forest. The bayou was but a few feet wider than the gunboats, and its banks were lined by gnarled and knotted old veterans of the forest, – live oaks, sycamore, and tupelo gum trees that had stood in majestic dignity on the banks of the dark and sullen stream for centuries. Sometimes majestic vistas would open; broad avenues carpeted with velvet turf, and walled in by the massive tree trunks, extending from the banks of the stream far back into the country. Again, the stately forests would be replaced by fields of waving corn or rice, with the tops of a row of negro cabins or the columned front of a planter's house showing in the distance. Then, as the flotilla steamed on, this fair prospect would disappear, and be replaced by noisome cypress brakes, hung thick with the funereal Spanish moss, and harboring beneath the black water many a noxious reptile.

So through the ever-changing scenery the gunboats moved along, making but little progress, but meeting with no serious obstacle, until one morning there appeared on a bit of high ground, some yards in advance of the leading gunboat, an army officer mounted on an old white horse. It was Gen. Sherman, and his troops were in camp near by. He greeted the naval forces cheerily, and, rallying Porter on the amphibious service into which his gunboats had been forced, warned him that he would soon have not a smokestack standing, nor a boat left at the davits.

"So much the better," said the undaunted admiral. "All I want is an engine, guns, and a hull to float them. As to boats, they are very much in the way."

A short time only was spent in consultation, and then Sherman with his forces left the bayou and plunged into the interior, first warning Porter that he would have a hard time getting any farther, even if the enemy did not come down and surround him. But Porter was not the man to abandon the advance, so long as there was water enough to float his gunboats. Besides, he had gained some ideas regarding navigation in the forests, that enabled him to move his fleet forward with more celerity than at first. When a tree blocked the course of the iron-clads, they no longer stopped to clear it away by work with the axes; but, clapping on all steam, the powerful rams dashed at the woody obstruction, and with repeated blows soon knocked it out of the way.

Soon after leaving Sherman, Porter saw that the difficulties he had thus far met and conquered were as nothing to those which he had yet to encounter. The comparatively broad stream up which he had been steaming came to an end, and his further progress must be through Cypress Bayou, a canal just forty-six feet wide..[?? – second period a smudge?] The broadest gunboat was forty-two feet wide, and to enter that narrow stream made retreat out of the question: there could be no turning round to fly. The levees rose on either side of the narrow canal high above the decks of the iron-clads, so that the cannon could not be sufficiently elevated to do effective work in case of an attack. But there were nine feet of water in the great ditch; and that was enough for Porter, who pressed boldly on.

The country into which the combined military and naval expedition was advancing was in truth the granary of Vicksburg. On all other sides of the beleaguered city, the Federal lines were drawn so closely that the wagons laden with farm produce could not hope to pass. But here, back of the city, and far from the camps of Grant's legions, the work of raising produce for the gallant people of Vicksburg was prosecuted with the most untiring vigor. The sight, then, of the advancing gunboats aroused the greatest consternation. From the deck of his vessel Porter could see the people striving to save their property from the advancing enemy. Great droves of cattle were being driven away far into the interior; negroes were skurrying in all directions, driving poultry and pigs to the safe concealment of the forest; wagons groaning under the weight of farm and garden produce could be seen disappearing in the distance. What the inhabitants could not save they destroyed, in order that it might not profit the invaders. A short distance from the mouth of the bayou "were six thousand bales of cotton piled up on opposite sides of the stream, ready to be taken aboard a steamer when the war should end. As the gunboats advanced slowly, making little headway against the two-knot current of the bayou, Porter saw two men, carrying lighted pine-knots, dash up to the cotton, and begin to set it afire. The admiral looked on in disgust. "'What fools these mortals be!'" said he to an officer standing at his side; "but I suppose those men have a right to burn their own cotton, especially as we have no way of preventing them."

"I can send a howitzer shell at them, sir," said the officer, "and drive them away."

But to this Porter demurred, saying that he had no desire to kill the men, and that they might do as they liked with their own. Accordingly the officers quietly watched the vandals, until, after twenty minutes' work, the cotton was blazing, and a dense mass of smoke cut off all vision ahead, and rose high in the air. Then Porter began to suspect that he had made a mistake. The difficulties of navigation in the bayou were great enough, without having smoke and fire added to them. Yet to wait for the cotton to burn up might cause a serious delay. On the high bank of the bayou stood a negro begging the sailors to take him aboard.

"Hallo, there, Sambo!" sung out Porter, "how long will it take this cotton to burn up?"

"Two day, massa," responded the contraband; "p'raps tree."

That ended the debate. "Ring the bell to go ahead fast," said the admiral to the pilot; and away went the flotilla at full speed, plunging into the smoke and fire. It was a hot experience for the sailors. The heavy iron-clads made but slow progress, and were scorched and blistered with the heat. The ports were all shut down, and the crews called to fire-quarters, buckets in hand. To remain on deck, was impossible. Porter and his captain made the trial, but had hardly entered the smoke when the scorching heat drove both into the shelter of an iron-covered deck-house. The pilot standing at the wheel seized a flag, and, wrapping it about his face and body, was able to stay at his post. As the flames grew hotter, the sailors below opened the main hatch, and, thrusting up a hose, deluged the deck with floods of water. So, without a man in sight, the huge iron ship moved along between the walls of flame. Suddenly came an enormous crash. The gunboat shivered, and for a moment stood still; then, gathering headway, moved on again, though with much ominous grating beneath her keel. Soon after she passed out of the smoke and heat, and all hands rushed on deck for a whiff of the fresh, cool air. Their first thought was of the cause of the collision; and, looking eagerly astern, they saw a heavy bridge, about fifty feet of which had been demolished by the tremendous power of the ram. This gave Porter a hint as to the force he had at his command; and thereafter bridges were rammed as a matter of course whenever they impeded the progress of the iron-clads. The astonishment of the people along the shore may well be imagined.

The great and formidable obstacles that stood in the path of the squadron were, as a rule, overcome by the exertion of the great powers of the steam-driven, iron-plated vessels; but at last there came a check, that, though it seemed at first insignificant, terminated the sylvan manœuvres of the iron-clad navy. After running the gantlet of the burning cotton, butting down trees, and smashing through bridges, the column entered a stretch of smooth water that seemed to promise fair and unobstructed sailing. But toward the end of this expanse of water a kind of green scum was evident, extending right across the bayou, from bank to bank. Porter's keen eye caught sight of this; and, turning to one of the negroes who had taken refuge on the gunboat, he asked what it was. "It's nuffin' but willows, sah," he replied. "When de water's out of de bayou, den we cuts de willows to make baskets with. You kin go troo dat like a eel."

Satisfied with this explanation, the admiral ordered the tug which led the column to go ahead. Under a full head of steam, the tug dashed into the willows, but began to slow up, until, after going about thirty yards, she stopped, unable to go forward or back. Undaunted by this unexpected resistance, Porter cried out that the "Cincinnati" would push the tug along; and the heavy gunboat, withdrawing a short distance to gain headway, hurled herself forward, and dashed into the willows with a force that would have carried her through any bridge ever built. But the old fable of the lion bound down by the silken net was here re-enacted. The gunboat did not even reach the tug. The slender willow-shoots trailed along the sides, caught in the rough ends of the iron overhang, and held the vessel immovable. Abandoning the attempt to advance, the gunboat strove to back out, but to no avail. Then hooks were rigged over the side to break away the withes, and men slung in ropes alongside vigorously wielded sharp cutlasses and saws; but still the willows retained their grip. Matters were now getting serious; and, to add to Porter's perplexity, reports came in that Confederate troops were coming down upon him. Then he began to lose confidence in his iron-clads, and wish right heartily for Sherman and his soldiers, of whose whereabouts he could gain no knowledge. The enemy did not leave him long in doubts as to their intention, and soon began a vigorous fire of shells from the woods. Porter stopped that promptly by manning his mortars and firing a few shells at a range measured by the sound of the enemy's cannon. The immediate silence of the hostile batteries proved the accuracy of the admiral's calculations, and gave him time to devise means for escaping from his perilous position.

How to do it without aid from Sherman's troops, was a difficult question; and in his perplexity he exclaimed aloud, "Why don't Sherman come on? I'd give ten dollars to get a telegram to him." The admiral was standing at the moment on the bank of the bayou, near a group of negroes; and an athletic-looking contraband stepped forward, and, announcing himself as a "telegram-wire," offered to carry the note "to kingdum kum for half a dollar." After sharply cross-questioning the volunteer, Porter wrote on a scrap of paper, "Dear Sherman, – Hurry up, for Heaven's sake. I never knew how helpless an iron-clad could be, steaming around through the woods without an army to back her."

"Where will you carry this?" asked Porter, handing the despatch to the negro.

"In my calabash kiver, massa," responded the messenger with a grin; and, stowing the paper away in his woolly hair, he darted away.

The telegram being thus despatched, Porter again turned his attention to the willows; and, a fortunate rise in the water having occurred, he was able to extricate his vessels and begin his retreat down the bayou. He was somewhat perplexed by the silence of the Confederates, from whom he had heard nothing since his mortars silenced their masked batteries. The conundrum was solved by the sound of wood-chopping in the forests ahead, and the discovery shortly after of two heavy logs lying athwart the bayou, and stopping the progress of the vessels. An hour's hard work with axe and saw removed this obstruction; and the tug, slipping through first, shot ahead to prevent any more tree-felling. The loud reports of her howitzer soon carried back to the fleet the news that she had come up with the enemy, and was disputing with them the right to the bayou.

The difficulties of the retreat were no less great than those of the advance, with the intermittent attacks of the enemy added. The work of removing heavy, soggy logs, half submerged beneath the black waters of the bayou, clearing away standing trees, and breaking up and removing Red-river rafts, wearied the sailors, and left them little spirit to meet the enemy's attacks. The faint sounds of wood-chopping in the distance told too well of the additional impediments yet in store for the adventurous mariners. Scouts sent out reported that the enemy had impressed great gangs of negroes, and were forcing them to do the work of felling the trees that were to hem in Uncle Sam's gunboats, for the benefit of the C.S.A. But the plans of the Confederates to this end were easily defeated. Porter had not only many willing arms at his command, but the powerful aid of steam. When the gunboats came to a tree lying across the bayou, a landing party went ashore and fastened large pulleys to a tree on the bank. Then a rope was passed through the block; and one end having been made fast to the fallen tree, the other was taken aboard a gunboat. The word was then given, "Back the iron-clad hard;" and the fallen monarch of the forest was soon dragged across the bayou and out of the way So expert did the jackies become in this work, that they were soon able to clear away the trees faster than the enemy could fell them. The tug then went ahead, and for a time put an end to further tree-chopping, and captured several of the negro axemen.

From the captured contrabands Porter learned that the attempt to cut off his retreat was directed by the military authorities at Vicksburg. This was a startling revelation. He had thought that the Confederates were in entire ignorance of his movement; and now it turned out that the wily Pemberton had kept a sharp lookout on the marauding gunboats, and was shrewdly planning for their capture. While Porter was pondering over this new discovery, a party of scouts came in, bringing in four captured Confederates, two of whom were commissioned officers. The commanding officer, a mere boy, was somewhat chagrined at being captured, but felt confident that his friends would recapture him shortly. Porter politely asked him to take a glass of wine and some supper.

"I don't care if I do," responded the youngster; "and I have the less compunction in taking it, as it belongs to us anyhow. In two hours you will be surrounded and bagged. You can't escape. How in the Devil's name you ever got here, is a wonder to me."

Porter smiled pleasantly, and, helping his guests lavishly, proceeded to question them on the numbers and position of the Confederate troops. He learned that a large body of troops had been sent out to surround the iron-clads, and were even then closing in upon the intruders. The danger was imminent, but Porter showed no trepidation.

"How far off are your troops?" he asked.

"About four miles. They will bag you at daylight," was the confident response.

"Well, gentlemen," said the admiral, "Gen. Sherman is now surrounding your forces with ten thousand men, and will capture them all before daylight." And so saying the admiral went on deck, leaving his captives lost in wonder; for the information carried to the Vicksburg authorities had made no mention of troops.

Though Porter had put on so bold a front before his captives, he really felt much anxiety for the fate of his iron-clads. He could hear nothing from Sherman, who might be thirty miles away for all he knew. Accordingly he retraced his course for a few miles, to throw the enemy off the scent, and the next day began again his descent of the bayou, bumping along stern foremost amid snags and standing trees. The enemy soon gave evidence that he was on the watch, and opened fire with his artillery from the rear. At this one gunboat steamed back and silenced the artillery for a time, after which she rejoined her fellows. Sharp-shooters in the thickets along the levee then began to grow troublesome; and the whistle of the rifle-balls, with an occasional ping as one struck the smokestack, warned the sailors that the deck of a gunboat in a narrow canal was no safe place in time of war. The high levees on either side of the bayou made it impossible to use the guns properly: so Porter turned them into mortars, and, by using very small charges of powder, pitched shells up into the air, dropping them into the bushes back of the levee. This somewhat checked the fire of the sharp-shooters, but the decks were still dangerous places to frequent. A rifle-ball struck Lieut. Wells in the head as he stood talking to Porter; and he fell, apparently dead, upon the deck. The admiral beckoned an officer to come and bear away the body; but the newcomer was also hit, and fell across the body of the first. Porter concluded that the locality was getting rather hot, and gladly stepped behind a heavy plate of sheet-iron, which an old quarter-master brought him with the remark, "There, sir, stand behind that. They've fired at you long enough."

From behind his shield, Porter looked out anxiously at the forces by which he was beleaguered. He could see clearly that the Confederates were increasing in numbers; and, when at last he saw a long gray column come sweeping out of the woods, his heart failed him, and for a moment he thought that the fate of his flotilla was sealed. But at that very moment deliverance was at hand. The Confederates were seen to fall into confusion, waver, and give way before a thin blue line, – the advance guard of Sherman's troops. The negro "telegram-wire" had proved faithful, and Sherman had come on to the rescue.

That ended the difficulties of the flotilla. The enemy, once brought face to face with Sherman's men, departed abruptly; and soon the doughty general, mounted on an old gray horse, came riding down to the edge of the bayou, for a word with Porter. Seeing the admiral on the deck of his gunboat, he shouted out, "Hallo! Porter, what did you get into such an ugly scrape for? So much for you navy fellows getting out of your element. Better send for the soldiers always. My boys will put you through. Here's your little nigger. He came through all right, and I started at once. Your gunboats are enough to scare the crows: they look as if you had got a terrible hammering."

Somewhat crestfallen, Porter remarked, that he "never knew what helpless things iron-clads could become when they got in a ditch, and had no soldiers about." As Sherman declined to come aboard, Porter went below to look after his two prisoners.

"Well, gentlemen," said he, as he entered the cabin, "you were right. We are surrounded by troops."

The two Confederates were greatly exultant, but assured Porter that they would see that he was kindly treated when taken into Vicksburg.

"To Vicksburg!" said he with mock amazement. "Who said any thing of Vicksburg?"

"Why, of course you'll be taken there as a prisoner, now that our men have surrounded you."

"Oh, you are mistaken there!" responded Porter. "The troops by whom I am surrounded are Sherman's boys, six thousand strong." And at this news the chagrined captives subsided, and began to consider the prospects of a trip to the North, and incarceration in one of the military prisons.

Sherman's army soon came up in force, and went into camp along the road that skirted the levee. As night fell, the scene took on a wild and picturesque air. In the narrow bayou lay the gunboats, strung out in single file along a line of half a mile. They bore many signs of the hard knocks they had received in their excursion through the woods. Boats, davits, steam-pipes, and every thing breakable that rose above the level of the deck, had been swept away by the overhanging boughs, or dashed to pieces by falling trees. The smoke-stacks and wheel-houses were riddled by the bullets of the Confederate sharp-shooters. The decks were covered with rubbish of all kinds, and here and there was a fissure that told of the bursting of some Confederate shell. The paint was blistered, and peeling off, from the effects of the cotton-fire through which the fleet had dashed.
