Perhaps Hooker's trouble was that he won his battle in anticipation, and won it too completely. What began as a simple attempt to maneuver Lee out of his impregnable lines back of Fredericksburg came before long to look like a strategic masterpiece that would win the war; as it took on this aspect it began to seem real before a shot had been
fired, and Hooker's contemplated triumph kept expanding until it burst. As the campaign got under way he remarked jauntily that Lee's army now was the legitimate property of the Army of the Potomac, and on the eve of battle he formally announced to all ranks that he had maneuvered so cunningly that the enemy must either fly ingloriously or come out and submit to destruction; and after the campaign was over he confessed frankly: "What I wanted was Lee's army; with that, Richmond would have been ours, and indeed all of Virginia."

Lee's army was exactly what Hooker got, but it came at him from the wrong direction when he was thinking about something else and so it was too much for him; and his real trouble was not so much his own vainglory as the fact that he was up against the wrong opponent. After all, Hooker planned very well, and although he executed poorly his advantage in numbers was large enough to rub out a good many mistakes. What he tried would have worked, against most generals. Against Lee it failed so completely that its basic excellence is too easily overlooked.
Hooker began by planning a cavalry sweep that would shear in behind the Confederate left, snip the railroads by which Lee got his supplies, and so compel him to retreat. (Once Lee was out in the open country the Army of the Potomac could doubtless attack him to advantage.) Two days after Mr. Lincoln went back to Washington, Hooker ordered his cavalry commander, Major General George Stoneman, to take his troopers across the upper Rappahannock near the line of the Orange & Alexandria Railroad and start operating in the enemy's rear, "inflicting on him every possible injury which will tend to his discomfiture and defeat." Stoneman set out, but as he began to cross the river a violent rainstorm blew up, the river rose and the unpaved roads went out of sight in mud. Stoneman considered an offensive impossible and recalled his advance guard, and the whole movement came to nothing.
2
Two weeks passed, and Hooker made a new plan, much more ambitious than the first. It was this plan that brought his army to Chancellorsville.
As before, the cavalry would cross the river and head for the Confederate rear, but this time its role would be comparatively minor. While the cavalry cut Lee's supply lines, the bigger part of the infantry of the Army of the Potomac would also march upstream, cross the Rappahannock and the Rapidan, and then march eastward behind Lee's left. In effect, this flanking column would be approaching Lee's line on Marye's Heights from the rear, and it would be only a little smaller than Lee's entire army.
This force was ordered to go first to Chancellorsville. When it moved from Chancellorsville—with Stoneman's cavalry spreading panic and destruction near Richmond, making it impossible for Lee's army to get either supplies or reinforcements—Lee would have to get out of Fredericksburg in a hurry. If he headed for Richmond, the Federal column could strike him ruinously in the flank; if he turned to fight at Chancellorsville, the rest of the Army of the Potomac, following hard from Fredericksburg, could pitch into him and he could be attacked in front and in rear simultaneously— which of course would be the end of him.
So went the plan. It was a good plan, and up to a point it worked well. The huge flanking column moved precisely as Hooker intended, and by the evening of April 30 he had four army corps at or near Chancellorsville. Shortly after nightfall he reached the place himself, radiating confidence, sure that he had the game in his hand.
He was sure, that is, with part of his mind, the part that he knew about: not sure, apparently, with the part that ran down out of sight in the darkness, where fears come from. Although it was at Chancellorsville that Hooker got out that strange announcement of the impending defeat of Lee's army, it was also at Chancellorsville that he ceased to look like a general who is about to win a great victory and began to resemble one who suspects that he will be beaten if he is not very cautious. He became cautious just a little too soon—a few miles and a few hours short of the victory he had talked about so much.
On the night April ended, Hooker had approximately 50,000 men at Chancellorsville, with 22,000 more on the way. Back at Falmouth, just above Fredericksburg, were 47,000 more, under Major General John Sedgwick, the competent commander of the VI Corps. Sedgwick and Hooker were hardly ten miles apart in a direct line, but as the roads went, roundabout on the United States Ford route, the distance was more than twice that far, and it could be dangerous to separate the two wings of an army so widely in the presence of General Lee. However, the separation would end very soon. On May 1 the force at Chancellorsville was to march eastward near the river, and after a few miles this march would uncover Banks' Ford, a river crossing hardly four miles from Falmouth, and the separated wings would be in touch again. Meanwhile, Sedgwick had laid pontoon bridges below Fredericksburg and had crossed part of his troops, hoping to convince Lee that he was about to attack. If this worked, Lee was not likely to notice what was going on at Chancellorsville, which would be fatal; if he did notice he would of course retreat in haste, in which case Sedgwick was ideally posted to pursue him and bring him to grief.

The real trouble with Hooker's plan was that it was brittle. It rested on the belief that Lee would react predictably to a series of challenges; if he did not, Federal strategy might need more flexibility than the plan allowed. It had been assumed, for instance, that when Stoneman and his cavalry galloped south Stuart and his cavalry would gallop after; but Stuart did nothing of the kind. The Yankee cavalry might do damage in the unprotected rear areas but Lee's army was the only thing that mattered now, and so Stuart kept his cavalry on Lee's flank to give the army the protection and the knowledge that might make the difference between victory and defeat. As a result he kept Lee posted about the advance and strength of Hooker's flanking force, and kept the flankers from finding out very much about Lee; and by the night of April 30 Lee knew that Sedgwick was bluffing and that the real threat was coming out of the Wilderness at Chancellorsville.
Then he refused to behave as expected. It seemed obvious that if he went to Chancellorsville at all he would take his entire force, because he was so badly outnumbered that he could hardly do anything else, and this of course would open the road for Sedgwick and Lee would eventually be caught between two fires. But simply because he was so terribly outnumbered, Lee was free to take preposterous chances; the odds against him were so long to begin with that it could not hurt much to lengthen them a bit, and anyway an opponent who believed that Lee would do the obvious under any circumstances was simply begging for trouble.
Stonewall Jackson wanted to smash Sedgwick before doing anything else, and although Lee was skeptical he told Jackson to study the ground carefully; if Jackson felt that it could be done Lee would order it. Jackson studied, concluded finally that Sedgwick was not smashable, and so reported, and Lee ordered the army over to Chancellorsville. But he did not take everybody. He detached 10,000 men, entrusted them to hard-fighting Major General Jubal Early, strengthened the contingent with extra artillery, saw that it was well posted on Marye's Heights, and instructed Early to keep Sedgwick from doing any harm.
It seemed folly to leave 10,000 men to oppose 47,000. But it would also have been folly for Lee to try to march back to Richmond with Yankee cavalry blocking the road ahead, four Yankee infantry corps on the immediate flank, and Sedgwick in hot pursuit; worse folly to let the army get pressed to death between the converging halves of the Army of the Potomac at Chancellorsville; folly in its highest form simply to do nothing, waiting at Fredericksburg for the executioner. What Lee did was risky, but it was less risky than the other options that were open . . . and anyway it was something General Hooker might not expect. And so on the night of April 30 and the morning of May 1 Lee and Jackson and everybody but Early's command marched toward Chancellorsville to meet Hooker.
Hooker gave them just time enough. Unaccountably, he lost his grip on the situation, somewhere between the afternoon of April 30 and the morning of May 1; the driving energy that had been his saving grace suddenly went out of him, and the army floundered. On this campaign it was Hooker's habit, every evening, to issue orders for the following day's movements. Yet on the night of April 30, when he proclaimed assured victory, Hooker issued no orders at all, although the advance that must be made the next day was the key to the success of the whole campaign. This advance would be short, and if made promptly it would be practically unopposed. By going forward a few miles the army would not only uncover Banks' Ford, which would end the isolation of Sedgwick's force, but would also emerge from the confusing Wilderness and reach open country where the Federal advantage in manpower and artillery could be exploited to the full. But Hooker spent most of the morning waiting at Chancellorsville. Not until eleven o'clock on May 1 was his army put in motion; then, with three corps advancing on separate roads, Hooker learned that the Confederates were not quite where he thought they were. The heads of his columns suddenly ran into Confederate skirmishers and there were bursts of rifle fire from the woods and hills that fringed the little clearings.
The opposition did not seem to be especially heavy, and the Federal commanders prepared to form lines of battle and clear the way, but Hooker's plan abruptly fell completely apart. Up from Chancellorsville came unexpected orders from headquarters: cancel the advance, break off the firing, and bring everybody back to a defensive position around the Chancellorsville crossroad.

The corps commanders were dumfounded and indignant, and Darius Couch of II Corps, their senior, hurried to headquarters to protest. Hooker tried to soothe him, saying: "I have got Lee just where I want him; he must fight me on my own ground." Couch went away, convinced (as he wrote later) that "my commanding general was a whipped man,"
5
and Couch was about right. From the day of his appointment up until this moment, Hooker had been all that a general ought to be; now, in the shadows of the Wilderness, he was alone with his responsibility and it was too much for him. He had planned to destroy Lee's army: now he was hoping that Lee's army would be obliging enough to destroy itself. All that happened to Hooker at Chancellorsville-—to him, and to the unlucky private soldiers who lived and died by his orders— was foreshadowed in his strange withdrawal on the afternoon of May 1.
Hooker drew his lines at Chancellorsville—long lines, and strong, with a bulging crescent on a low plateau east and south of the Chancellorsville house, one wing on the left stretching all the way up to the Rappahannock, the other drawn up along the turnpike, facing south. Here Hooker waited, his men using axes and spades to strengthen their field works, and the afternoon ended and night came. It was an uneasy night, with a big moon putting a streaky light on the landscape, Confederate patrols prowling about in front to see how things were, Stuart's squadrons sweeping all the roads and keeping the Federals from seeing anything except what the moonlight would show, a man from a rifle pit in the thickets. To Brigadier General Daniel Butterfield, his chief of staff, who had stayed at Falmouth, Hooker sent a message: all of Stuart's cavalry was in his front, which meant that Stoneman ought to "do a land-office business" far to the south; Sedgwick was to watch the Confederates closely and keep them from doing whatever they tried to do; and at Chahcellorsville "I think the enemy in his desperation will be compelled to attack me on my own ground."
8
This meant that it was Lee's turn now; Hooker had given up the initiative and Lee had grasped it. That night, around a campfire in the woods just out of gunshot from Hooker's lines, Lee and Stonewall Jackson met to consider the best way to strike their foes.
They were not nearly strong enough to make a frontal assault, and the Federal left could not be turned, but Stuart's cavalry had learned that Hooker's right was "in the air"; the line went west from Chancellorsville for two or three miles and then simply ended, wholly unprepared for an attack from the west. If the Confederates could mass troops four or five miles west of Chancellorsville, these troops could march straight into Hooker's rear and the Federal position would collapse. Hooker had placed the bigger part of his army in position to do this to Lee but he had failed to go on and do it; as a result he had given Lee the chance to do exactly the same thing to him, and of all the soldiers in North America Lee and Jackson were the ones most likely to see and to accept this opportunity. They lost little time coming to a decision, and shortly after the sun came up on May 2 Stonewall Jackson put his army corps on the road and set off to crumple the Federal flank.
7
Jackson was the man who would strike the blow, and much would depend on his skill and daring; but the real responsibility was Lee's, and the risk he was taking now made all his earlier risks seem mild. He had already divided his army, leaving 10,000 men to hold four times their number at Fredericksburg, and he had with him at Chancellorsville no more than 42,000 infantry. Now he was dividing this inadequate force, sending 28,000 off with Jackson on a twelve-mile flanking march that would unquestionably take most of the day. For about ten hours Lee would have just 14,000 men to oppose most of Hooker's army, 70,000 men. Ten hours could bring him to ruin if Hooker once saw what was happening.
Hooker actually did see a little of it, but he misinterpreted what he saw and in the end was worse off than if he had seen nothing at all. After Jackson moved, Lee kept his 14,000 busy, shifting men about, opening sudden bursts of artillery and infantry fire, giving indications that he was about to assault the Federal left. Hoping that such an attack would be made, Hooker accepted these indications at face value. But Jackson's march was discovered. Making his long detour to the west, Jackson at one place had to turn sharply to his left to get past a patch of open country some three miles from Hooker's right-center, and the Federal outposts saw a long column of Rebel infantry accompanied by artillery and wagons—the wagons, of course, being nothing more than Jackson's ambulances and ammunition train. For a moment Hooker was on the verge of full awareness, and he ordered Major General Oliver Otis Howard, who held the extreme right, to prepare for a flank attack.

Then he had a second thought, which led him to disaster.
