Pemberton did not share in the fraternization, not only because of his present sadness, his sense of failure, and his intimation of what the reaction of his adoptive countrymen would be when they got the news of what had happened here today, but also because of his nature, which was invariably distant and often forbidding. For him, congeniality had been limited mainly to the family circle he had broken and been barred from when he threw in with the South. Even toward his own officers he had always been stiffly formal, and now toward Grant, who came through the lines that morning on his way to confer with Porter at the wharf, he was downright icy; indeed, rude. Perhaps it was the northern commander’s show of magnanimity, when he knew that such concessions as had been granted—parole of the garrison, for example, instead of a long boat ride to prison camps in Ohio and Illinois—had been the result of hard bargaining and a refusal to yield to his original demand for unconditional surrender. In any event, one of his staff found Pemberton’s manner “unhandsome and disagreeable in the extreme.” No one offered Grant a seat when he called on Pemberton in a house on the Jackson road, this officer protested, and when he remarked that he would like a drink of water, he was told that he could go where it was and help himself. He did not seem perturbed by this lack of graciousness, however; he went his way, taking no apparent umbrage, content with the spoils of this Independence Day, which were by far the greatest of the war, at any rate in men and materiel. Confederate casualties during the siege had been 2872 killed, wounded, and missing, while those of the Federals totaled 4910; but now the final tally of captives was being made. It included 2166 officers, 27,230 enlisted men, and 115 civilian employees, all paroled except one officer and 708 men, who preferred to go north as prisoners rather than risk being exchanged and required to fight again. In ordnance, too, the harvest was a rich one, yielding 172 cannon, surprisingly large amounts of ammunition of all kinds, and nearly 60,000 muskets and rifles, many of such superior quality that some Union regiments exchanged their own weapons for the ones they found stacked when they marched in.
One additional prize there was, richer by far than all the rest combined and to which they had served as no more than prologue. The Mississippi would return to its old allegiance as soon as one remaining obstruction had been removed, and that allegiance would be secure as soon as one continuing threat had been abolished. The obstruction—Port Hudson—was not really Grant’s concern except for the dispatching of reinforcements, which he could now quite easily afford, to help Banks get on with the job. He kept his attention fixed on Joe Johnston—the threat—who continued to hover, off to the east, beyond the Big Black River. Conferring with Porter, Grant requested his co-operation in flushing out the rebels up the Yazoo, re-established there by Johnston while the Federals were concentrating on the reduction of Vicksburg. As usual, the admiral was altogether willing; he assigned an ironclad and two tinclads the task of escorting 5000 infantry upstream to retake Yazoo City, which the Confederates had refortified since their flight from the approaching gunboats back in May. But the northern army commander’s main concern was Johnston himself and the force he was assembling west of Jackson. Yesterday, while surrender negotiations were under way, Grant had notified Sherman, whose troops were already faced in that direction, that he was to strike eastward as soon as Vicksburg fell. “I want Johnston broken up as effectually as possible, and roads destroyed,” he wired. This message was followed shortly by another, in which he was more specific as to just what breakage was expected. “When we go in,” he told his red-haired lieutenant, “I want you to drive Johnston from the Mississippi Central Railroad, destroy bridges as far as Grenada with your cavalry, and do the enemy all the harm possible. You can make your own arrangements and have all the troops of my command, except one corps—McPherson’s, say. I must have some troops to send to Banks, to use against Port Hudson.”
As it turned out, there was no need for more troops at Port Hudson. All that was required was valid evidence that its companion bluff 240 miles upriver was in Union hands, and this arrived before the reinforcements: specifically, during the early hours of July 7. That evening Gardner received from one of his three brigade commanders—Miles, whose position on the far right afforded him a view of the river, as well as of the extreme left of the Federal intrenchments—a report of strange doings by the enemy, ashore and afloat: “This morning all his land batteries fired a salute, and followed it immediately [by another] with shotted guns, accompanied by vociferous yelling. Later in the day the fleet fired a salute also. What is meant we do not know. Some of them hallooed over, saying that Vicksburg had fallen on the 4th instant. My own impression is that some fictitious good news has been given to his troops in order to raise their spirits; perhaps with a view of stimulating them to a charge in the morning. We will be prepared for them should they do so.”
The colonel’s men shared his skepticism as well as his resolution, even when confronted with documentary evidence in the form of a “flimsy” tossed into their lines, bearing the signature of the Federal adjutant-general and announcing Pemberton’s surrender three days ago. “That’s another damned Yankee lie!” a butternut defender shouted back. But Gardner himself was not so sure. He had fought well, inflicting 4363 casualties at a cost of only 623 of his own, and though by now the trenches were less than twenty feet apart in places and the enemy was obviously about to launch another massive assault, which was likely to succeed at such close range, he was prepared to fight still longer if need be. On the other hand, it was no part of his duty to sacrifice the garrison for no purpose—and obviously Port Hudson’s purpose, or anyhow its hope of survival, was tied to that of Vicksburg. If the Mississippi bastion had fallen, so must the Louisiana one, exposed as it would be to the possible combination of both Union armies. So Gardner adopted the logical if somewhat irregular course of inquiring of his opponent, by means of a flag of truce next morning, as to whether the report of Vicksburg’s fall was true. And when Banks supplied confirming evidence, in the form of a dispatch Grant had sent on the surrender date, Gardner decided that the time for his own capitulation was at hand. Final details were not worked out until the following day, July 9, when the besiegers marched in and took possession, but a train of wagons had already entered Port Hudson the previous afternoon, loaded with U.S. Army rations for the half-starved garrison. Banks combined firmness and generosity. Though his terms had been unconditional, he paroled his 5935 enlisted captives and sent only their 405 officers to New Orleans to await exchange or shipment north. Moreover, having acquired some 7500 excellent rifles and 51 light and heavy guns, he closed the formal surrender ceremony with “a worthy act, well merited.” Thus his adjutant characterized the gesture in describing it years later. “By General Banks’s order, General Gardner’s sword was returned to him in the presence of his men, in recognition of the heroic defense.”
If there was haste in the northern commander’s method, including parole of all his enlisted prisoners, there was also method in his haste. Albeit they were the sweeter, being his first, Banks was no more inclined than Grant to sit down and enjoy the fruits of his victory; for just as the latter took out after Joe Johnston as soon as Vicksburg fell, so did the former concern himself with Dick Taylor as soon as Port Hudson followed suit. Faced as he was with the departure of the nine-month volunteers who made up a considerable portion of his army, Banks had to choose between using the remainder as guards for the captured garrison or as a mobile force for driving out the reported 13,000 Confederates who had moved into his rear and were threatening New Orleans from Bayou Lafourche and Berwick Bay. Quite aside from the pleasure he derived from being generous to a defeated foe, that was why he paroled nearly 6000 of his 6340 prisoners: to get them off his hands and thus be free to deal with Taylor. Having decided, he wasted no time. While the surrender ceremony was in progress he put Weitzel’s and Grover’s divisions aboard transports and sent them at once to Donaldsonville, where they would begin their descent of the Lafourche, disposing of infiltrated rebels a
s they went. The debarkation was completed on July 11; next afternoon the two blue divisions began their advance down opposite banks of the bayou. Early the following morning, however—July 13 at Koch’s Plantation, six miles from Donaldsonville—Weitzel’s two west-bank brigades, and indirectly Banks himself, were given a cruel demonstration of the fact that haste sometimes made waste, even in pursuit.
Tom Green, with his own and Major’s brigade of mounted Texans, had been having a fine time disrupting traffic on the Mississippi with the guns he had established on its right bank, ten miles below the town. Though they could do no real damage to the Essex, which came down to challenge them, they did succeed in driving the ironclad off and puncturing the steam-drums of several less heavily armored vessels. A battery commander referred to the 12-foot levee as “the best of earthworks,” and Green was prepared to stay there indefinitely, finding balm in his present success for the sting of the recent setback at Fort Butler. After three days of such fun, however, he learned of the arrival of ten transports at Donaldsonville and the debarkation of two blue divisions with better than five times his number of men. Determined not to leave without a fight, whatever the odds, he pulled back from the river, crossed the Lafourche, and lay in wait for what was coming. What was coming was Weitzel, supported by Grover across the way. Green struck hard, soon after sunrise of July 13, caught the bluecoats off guard, and threw them into such hasty retreat that they abandoned three of their guns to their pursuers. They lost 50 killed, 223 wounded, and 186 captured or missing, while Green lost 9 killed and 24 wounded. He withdrew westward, unmolested, and rejoined Taylor at Vermilionville, that general having retired with all his spoils from Brashear City when he learned of Gardner’s surrender and the intended return downriver of the besieging army. By no means strong enough for a full-scale battle with the greatly superior forces of the Federals near their base, he was content to wait for them to attempt a second ascent of the Teche. They would find him better equipped for resistance than he had been before his recent brief but profitable drive to the outskirts of New Orleans.
Banks accepted the Koch’s Plantation check with his usual easy grace, even setting aside a court-martial’s findings that one of Weitzel’s brigade commanders had been guilty of drunkenness on duty and misconduct in the presence of the enemy. The former Speaker was looking for no scapegoat; he would take whatever blame there was, along with the praise, as designer and director of the campaign from start to finish. And of praise there was much. It was Banks, after all, who had removed the final obstruction to Union control of the Mississippi, following Grant’s extraction of “the nail that held the South’s two halves together.” On July 16, one week after the fall of Port Hudson, the unarmed packet Imperial tied up at New Orleans and began unloading cargo she had brought unescorted from St Louis. For the first time in thirty months, the Father of Waters was open to commerce from Minnesota to the Gulf.
Meanwhile Porter and Sherman had gone about their assignments, though for both there had been irksome delays followed by mishaps for which irksome was all too mild a word; Porter’s, in fact, had occurred on the same day as Weitzel’s, and while it had been considerably less bloody it was also a good deal more expensive. Originally intended as reinforcements for Banks, since they had spent less than a month in the Vicksburg trenches, 5000 men of Herron’s division were shifted to lighter-draft transports on July 11, when news of the fall of Port Hudson arrived, and set out up the Yazoo next morning, escorted by two 6-gun tinclads and the 14-gun ironclad Baron de Kalb, formerly the St Louis but rechristened when it developed that the navy already had a warship by that name. One of the original seven built by James Eads in the fall of ’61 and a veteran of all the major engagements on the Tennessee, the Cumberland, and the Mississippi north of Vicksburg, she had carried the flag eight weeks ago on a similar expedition to Yazoo City and beyond, which had resulted in much damage to the enemy at no cost to the fleet. This last was not to be the case this time, however. Isaac Brown, who had sunk the De Kalb’s sister ship Cairo with a demijohn of powder up this same winding river in December, was back again with forty survivors of the crew from his lost ram Arkansas, and he had plans for a repeat performance. His navy artillerists managed to drive the ironclad back around the bend when she appeared below the town at noon of July 13, but a Tarheel regiment assigned to the place by Johnston withdrew on learning that Herron had landed three of his own with instructions to bag the defenders. Obliged to pull back for lack of support, Brown and his sailors left something behind them in addition to their guns: as Porter and Herron presently discovered. The two were on the bridge of the flagship, steaming slowly upstream toward the undefended town, when—just after sunset, abreast of the yards where, about this time a year ago, the Arkansas had acquired her rusty armor—one of Brown’s improvised torpedoes exploded directly under her bow. As she began to settle, another went off under her stern, which hastened her destruction. Within fifteen minutes, though all aboard managed to escape with nothing worse than bruises, she was on the muddy bottom, providing a multichambered home for gars and catfish. Herron, having survived this violent introduction to one of the dangers involved in combined operations, went ashore to complete his share of the mission, afterwards reporting the destruction of the Yazoo City fortifications and five of the nine rebel steamboats found lurking in the vicinity, together with the capture of some 300 prisoners, six guns, and about 250 small-arms, as well as 2000 bales of cotton and 800 horses and mules which he commandeered from the planters roundabout. He was enthusiastic; no less than 50,000 more bales were awaiting discovery and seizure in the region, he declared. Porter, on the other hand, summed up the operation somewhat ruefully. “But for the blowing up of the Baron de Kalb, it would have been a good move,” he informed his superiors, and he added, by way of extenuating this loss of his fourth ironclad since December: “While a rebel flag floats anywhere the gunboats must follow up. The officers and men risk their lives fearlessly on these occasions, and I hope the Department will not take too seriously the accidents which happen to the vessels when it is impossible to avoid them.”
Sherman made no such apology, though his particular mishap had occurred the day before and had been preceded by a week of hot and profitless activity. Grant’s instructions for him to “do the enemy all the harm possible,” accompanied as they were by the prospect of having close to 50,000 troops with which to carry them out, had put the red-haired Ohioan in what he liked to call “high feather,” and when they were followed next day—July 4—by the news that Vicksburg had fallen, his excitement reached fever pitch. “I can hardly restrain myself,” he replied. Nor did he: adding, “This is a day of jubilee, a day of rejoicing to the faithful.… Already are my orders out to give one big huzza and sling the knapsack for new fields.” Those new fields lay on the far side of the Big Black, however, which was now past fording because of a sudden four-foot rise resulting from heavy rains upstate. Sherman spent two days throwing bridges at Birdsong’s Ferry and Messinger’s Ford and due east of Bovina, thus providing a crossing for each of his three corps, and on July 6 the “Army of Observation,” so called from the days of the siege, passed over the river in pursuit of Johnston, who had retired toward Jackson the day before, on learning of Pemberton’s surrender. As the rebels withdrew eastward along roads that were ankle-deep in dust—no matter how many inches of rain had fallen upstate, not a drop had fallen here in weeks—they made things difficult for their pursuers by leading animals into such few ponds as had not dried in the heat, then killing them and leaving their carcasses to pollute the water. It was Johnston’s intention not only to delay his opponent by such devices, but also to goad him into attempting a reckless, thirst-crazed assault on the Jackson intrenchments, which the Confederates had repaired and improved since Grant’s departure and in which they had taken refuge by the time the superior Federal force completed its crossing of the Big Black, twenty-five miles away.
