So Bruinsburg it was. By midmorning of this last day of April—while Sherman was launching his demonstration against Haines Bluff, fifty air-line miles to the north, and Grierson was pressing southward along the railroad below Brookhaven, the same distance to the east—all four of McClernand’s divisions and one of McPherson’s, some 23,000 men in all, had completed their debarkation and were slogging inland toward Port Gibson. “When this was effected,” Grant declared years later, “I felt a degree of relief scarcely ever equaled since.” Then he told why. “I was now in the enemy’s country, with a vast river and the stronghold of Vicksburg between me and my base of supplies. But I was on dry ground on the same side of the river with the enemy. All the campaigns, labors, hardships, and exposures from the month of December previous to this time that had been made and endured were for the accomplishment of this one object.”

For all his northern birth and starchy manner, which some continued to find personally distasteful, Pemberton by now had either sustained or won the confidence not only of his military superiors but also of the people of Mississippi, who came within his charge. His four-month sequence of successes in the face of threats from all points of the compass far outweighed their original prejudice against him. On May Day, for example—unaware that Sherman was knocking at Vicksburg’s upper gate or that Grant, with half his army over the river, already was marching inland from below—an editor in the capital, where the department commander had his headquarters, was taking a sanguine view of the situation. “It would be idle to say that our state and country was not in a position of great peril,” he declared. “Yet, strange as it may seem to our readers, we have never felt more secure since the fall of Donelson. The enemy will never reach Jackson; we are satisfied of that.… General Pemberton, assisted by vigilant and accomplished officers, is watching the movements of the enemy, and at the proper time will pounce upon him. Let us give the authorities all the assistance we can, and trust their superior and more experienced judgment as to the management of the armies. We know we have a force sufficient, if properly handled, not only to defeat but to rout and annihilate Grant if he ventures far from his river base.” As for doubts as to the proper handling of this sufficient force: “Let any man who questions the ability of General Pemberton only think for a moment of the condition the department was in when he was first sent here. No general has evinced a more sleepless vigilance in the discharge of his duty, or accomplished more solid and gratifying results.” Nor was this merely the opinion of one uninformed civilian. With reservations, Joe Johnston shared his view. Despite the gloom into which his inspection of the Vicksburg defenses had thrown him, back in December, the Virginian since had warmed to the Pennsylvanian as a result of his apparent skill in fending off the combinations designed for his destruction. In mid-March, reviewing the situation from three hundred miles away in Tennessee, he congratulated him handsomely. “Your activity and vigor in the defense of Mississippi must have secured for you the confidence of the people of Mississippi,” he wrote, and added: “I have no apprehension for Port Hudson from Banks. The only fear is that the canal may enable Grant to unite their forces. I believe your arrangements at Vicksburg make it perfectly safe, unless that union should be effected.”
Applause was one thing, assistance quite another: as Pemberton soon found out. Despite the denial of help from the vast department across the river, and despite the January transfer of three quarters of his cavalry to Middle Tennessee, he was so encouraged by the flooding of Grant’s canal in March that he mistook the subsequent withdrawal of the diggers to Milliken’s Bend for an abandonment by the Federals of their entire campaign. On April 11 he notified Johnston that the canal was no longer a danger, that Grant appeared to be pulling back to Memphis, and that he was therefore sending, as requested, a brigade to reinforce Bragg at Tullahoma. Five days later, however, with the blue army still in evidence on the opposite bank and Porter’s gunboats preparing for their run past the batteries that night, he recalled the detached brigade, which by then was in northern Mississippi. “[Grant’s] movement up the river was a ruse,” he wired Johnston. “Certainly no more troops should leave this department.” In fact, he said, it was he who stood in gravest need of help. Nothing came of that. Then on April 20, with Porter’s ironclads riding at anchor near New Carthage, McClernand moving farther down the Louisiana bank, and Grierson on the rampage east of Grenada—“part and parcel of the formidable invasion preparing before my eyes”—Pemberton stepped up his plea for reinforcements: especially for the return of his 6000 troopers under Van Dorn, the loss of whom had left him three-fourths blind. “Heavy raids are making from Tennessee deep into this state,” he warned. “Cavalry is indispensable to meet these expeditions. The little I have is … totally inadequate. Could you not make a demonstration with a cavalry force on their rear?” He protested that he had “literally no cavalry from Grand Gulf to Yazoo City, while the enemy is threatening to [cross] the river between Vicksburg and Grand Gulf, having now twelve vessels below the former place.” Johnston, obliged as he presently was to send Forrest to Alabama after Streight, not only would not agree to make a demonstration against West Tennessee; he also declined to lessen the strength of Bragg’s mounted arm, which included Wheeler and Morgan as well as Forrest and Van Dorn, despite the fact that Van Dorn was nominally on loan from Pemberton. It turned out, moreover, that the Pennsylvania’s previous successes worked against him now. Matters had seemed as dark several times before, in the course of the past four months, and he had managed to survive without assistance; apparently Johnston believed he would do as well again. At any rate he was still of his former opinion: “Van Dorn’s cavalry is absolutely necessary to enable General Bragg to hold the best part of the country from which he draws supplies.”
In effect this amounted to signing Van Dorn’s death warrant, since it kept him within range of the Tennessee doctor’s wife and her husband’s pistol. Pemberton was inclined to think that in the end it might amount to much the same thing for Vicksburg, which Jefferson Davis referred to as “the nailhead that held the South’s two halves together.” For suddenly now the news grew more alarming. Two nights later, April 22, five unarmored steamboats ran the batteries, obviously to provide the means for a crossing, somewhere below, by the bluecoats slogging down the western bank. Throughout the week that followed, Pemberton sent what little cavalry he had in pursuit of Grierson, whose raiders were disrupting the interior of the state and playing havoc with his lines of supply and communication. Then on April 29 word came from Brigadier General John S. Bowen, commanding at Grand Gulf, that the place was under heavy attack by gunboats attempting to soften him up for an assault by infantry waiting in transports across the river at Hard Times. Scarcely had the news arrived next morning that the ironclads had retired, severely battered, than Pemberton was notified that Haines Bluff was under similar pressure to the north. By the time he learned that this too had been beaten off, a follow-up message from Bowen informed him that the Union fleet had slipped past Grand Gulf in the darkness, transports and all, and was unloading soldiers in large numbers at Bruinsburg, ten miles below. Then came word that the Federals had resumed their pounding of Haines Bluff. Deciding that the downriver threat was the graver of the two, Pemberton resolved to reinforce Bowen, whom he instructed to contest the blue advance on Port Gibson.
On May Day, with the issue still in doubt below—so he thought, though it could scarcely be in doubt for long; the enemy strength was reported at 20,000 men, while Bowen had considerably less than half that many—he appealed once more to Johnston for assistance, bolstering his plea with a wire directly to the President. Davis replied that, in addition to urging Johnston to send help from Tennessee, he was doing all he could to forward troops from southern Alabama. Secretary Seddon, alerted to the danger, informed Pemberton that “heavy reinforcements” would start at once by rail from Beauregard in Charleston. Both messages were gratifying, communicating assurance of assistance from above.
But all the harassed Vicksburg commander got from Johnston was advice. “If Grant’s army lands on this side of the river,” the Virginian replied from Tullahoma, “the safety of Mississippi depends on beating it. For that object you should unite your whole force.”
A Georgia-born West Pointer, Bowen had left the old army after a single hitch as a lieutenant and had prospered as a St Louis architect before he was thirty, at which age he offered his sword to the newly formed Confederacy. Promoted to brigadier within ten months, he now was thirty-two and eager for further advancement, having spent more than a year in grade because of a long convalescence from a wound taken at Shiloh, where he led his brigade of Missourians with distinction. On the afternoon of April 30, marching his 5500 soldiers out of Grand Gulf and across Bayou Pierre to meet Grant’s 23,000 moving inland from Bruinsburg after their downriver creep past his blufftop guns in the darkness, he carried proudly in his pocket a dispatch received last night from Pemberton, congratulating him on the repulse of Porter’s ironclads: “In the name of the army, I desire to thank you and your troops for your gallant conduct today. Keep up the good work.… Yesterday I warmly recommended you for a major-generalcy. I shall renew it.” Bowen had it very much in mind to keep up the good work. Despite the looming four-to-one odds and the changed nature of his task now that he and the blue invaders were on the same bank of the river, he welcomed this opportunity to deal with them ashore today as he had dealt with them afloat the day before. Four miles west of Port Gibson before nightfall, he put his men in a good defensive position astride a wooded ridge just short of a fork in the road leading east from Bruinsburg. Presently the Federals came up and his pickets took them under fire in the moonlight. Artillery deepened the tone of the argument, North and South, but soon after midnight, as if by mutual consent, both sides quieted down to wait for daylight.
McClernand opened the May Day fight soon after sunrise, advancing all four of his divisions under Brigadier Generals Peter Osterhaus, A. J. Smith, Alvin Hovey, and Eugene Carr. The road fork just ahead placed him in something of a quandary, lacking as he did an adequate map, but this was soon resolved by a local Negro who informed him that the two roads came together again on the near side of Port Gibson, his objective. He sent Osterhaus to the left as a diversion in favor of the other three commanders, who were charged with launching the main effort on the right. Grant came up at midmorning to find the battle in full swing and McClernand in some confusion, his heavily engaged columns being out of touch with each other because the two roads that wound along parallel ridges—“This part of Mississippi stands on edge” was how Grant put it—were divided by a timber-choked ravine that made lateral communication impossible. The result was that McClernand’s right hand quite literally did not know what his left was doing, though the fact was neither was doing well at all. In his perplexity he called for help from McPherson, who supplied it by sending one brigade of Major General John A. Logan’s division to the left and another to the right. “Push right along. Close up fast,” the men heard Grant say as they went past the dust-covered general sitting a dust-covered horse beside the road fork. They did as he said, and arrived on the left in time to stall a rebel counterattack that had already thrown Osterhaus off balance, while on the right they added the weight needed for a resumption of the advance. Outflanked and heavily outnumbered on the road to the south, Bowen at last had to pull back to the outskirts of Port Gibson, where he rallied his men along a hastily improvised line and held off the blue attackers until nightfall ended the fighting.
Casualties were about equal on both sides; 832 Confederates and 875 Federals had fallen or were missing. Bowen had done well and he knew it, considering the disparity of numbers, but he also knew that to fight here tomorrow, against lengthened odds and without the advantage of this morning’s densely wooded terrain, would be to invite disaster. At sundown he notified Pemberton that he would “have to retire under cover of night to the other side of Bayou Pierre and await reinforcements.” Pemberton, who had arrived in Vicksburg from Jackson by now, had already sent word that he was “hurrying reinforcements; also ammunition. Endeavor to hold your own until they arrive, though it may be some time, as the distance is great.” At 7.30, having received Bowen’s sundown message, he rather wistfully inquired: “Is it not probable that the enemy will himself retire tonight? It is very important, as you know, to retain your present position, if possible.… You must, however, of course, be guided by your own judgment. You and your men have done nobly.” But Bowen by then had followed up his first dispatch with a second: “I am pulling back across Bayou Pierre. I will endeavor to hold that position until reinforcements arrive.” He withdrew skillfully by moonlight, unpursued and unobserved, destroying the three bridges over the bayou and its south fork, northwest and northeast of Port Gibson, and took up a strong position on the opposite bank, covering the wrecked crossing of the railroad to Grand Gulf, which he believed would be Grant’s next objective.
But Grant did not come that way, at least not yet. Finding Port Gibson empty at dawn, he pressed on through and gave James Wilson a brigade-sized detail with which to construct a bridge across the south fork of Bayou Pierre, just beyond the town. Wilson was experienced in such work, having built no less than seven such spans in the course of the march from Milliken’s Bend, and besides he had plenty of materials at hand, in the form of nearby houses which he tore down and cannibalized. By midafternoon the job was finished, “a continuous raft 166 feet long, 12 feet wide, with three rows of large mill-beams lying across the current, and the intervals between them closely filled with buoyant timber; the whole firmly tied together by a cross-floor or deck of 2-inch stuff.” So Wilson later described it, not without pride, adding that he had also provided side rails, corduroy approaches over quicksand, and abutments “formed by building a slight crib-work, and filling in with rails covered by sand.” Grant was impressed, but he did not linger to admire the young staff colonel’s handiwork. The second of McPherson’s three divisions having arrived that morning, he was given the lead today, with orders to march eight miles northeast to Grindstone Ford, which he reached soon after dark. He was prevented from crossing at once because the fine suspension bridge had been destroyed at that point, but Wilson was again at hand and had it repaired by daylight of May 3, when McPherson pressed on over. Near Willow Springs, two miles beyond the stream, he encountered and dislodged a small hostile force which retreated toward Hankinson’s Ferry, six miles north, where the main road to Vicksburg crossed the Big Black River. Instructing McPherson to keep up the march northward in pursuit, Grant detached a single brigade to accompany him westward in the direction of Grand Gulf.
McClernand, coming along behind McPherson, whom he was ordered to follow north, was alarmed to learn what Grant had done, striking off on his own like that, and sent a courier galloping after him with a warning: “Had you not better be careful lest you may personally fall in with the enemy on your way to Grand Gulf?” But Grant was not only anxious to reach that place as soon as possible, and thus reestablish contact with the navy and with Sherman, who was on the march down the Louisiana bank; he also believed that Bowen, chastened by yesterday’s encounter, would fall back beyond the Big Black as soon as he discovered that his position on Bayou Pierre had been turned upstream. And in this the northern commander was quite right. Reinforcements had reached Bowen from Jackson and Vicksburg by now, but they only increased his force to about 9000, whereas he reckoned the present enemy strength at 30,000, augmented as it was by a full division put ashore at Bruinsburg the night before. When he learned, moreover, that this host had bridged both forks of Bayou Pierre to the east of Port Gibson and was headed for the crossings of the Big Black, deep in his rear, he lost no time in reaching the decision Grant expected. At midnight, finding that his staff advisers “concurred in my belief that I was compelled to abandon the post at Grand Gulf,” he “then ordered the evacuation, the time for each command to move being so fixed as to avoid any delay or confusion.” The re
trograde movement went smoothly despite the need for haste. Bringing off all their baggage—which Pemberton, when informed of their predicament, had authorized them to abandon lest it slow their march, but which Bowen declared he was “determined to and did save”—the weary veterans and the newly arrived reinforcements set off northward, leaving the blufftop intrenchments, which they had defended so ably against the ironclad assault four days ago, yawning empty behind them in the early morning sunlight.
Soon after they disappeared over the northern horizon Porter arrived with four gunboats, intending to launch a new attack. He approached with caution, remembering his previous woes and fearing a rebel trick, but when he found the Grand Gulf works abandoned he did not let that diminish his claim for credit for their reduction. “We had a hard fight for these forts,” he wrote Secretary Welles, “and it is with great pleasure that I report that the Navy holds the door to Vicksburg.” He announced that his fire had torn the place to pieces, leaving it so covered with earth and debris that no one could tell at a glance what had been there before the bombardment. “Had the enemy succeeded in finishing these fortifications no fleet could have taken them,” he declared, quite as if he had subdued the batteries in the nick of time, and added: “I hear nothing of our army as yet; was expecting to hear their guns as we advanced on the forts.”
He heard from “our army” presently with the arrival of its commander, who had got word of the evacuation while en route from Grindstone Ford and had ridden ahead of the infantry with an escort of twenty troopers. Grant was glad to see the admiral, but most of all—after seven days on a borrowed horse, with “no change of underclothing, no meal except such as I could pick up sometimes at other headquarters, and no tent to cover me”—he was glad to avail himself of the admiral’s facilities. After a hot bath, a change of underwear borrowed from one of the naval officers, and a square meal aboard the flagship, he got off a full report to Halleck on the events of the past four days. “Our victory has been most complete, and the enemy thoroughly demoralized,” he wrote. Bowen’s defense of Port Gibson had been “a very bold one and well carried out. My force, however, was too heavy for his, and composed of well-disciplined and hardy men who know no defeat and are not willing to learn what it is.” After this unaccustomed flourish he got down to the matter at hand. “This army is in the finest health and spirits,” he declared. “Since leaving Milliken’s Bend they have marched as much by night as by day, through mud and rain, without tents or much other baggage, and on irregular rations, without a complaint and with less straggling than I have ever before witnessed.… I shall not bring my troops into this place, but immediately follow the enemy, and, if all promises as favorable hereafter as it does now, not stop until Vicksburg is in our possession.”
