In the years after the Civil War, a Confederate general wrote something no other Southern officer was willing to put on paper. He said Ulysses S. Grant’s strategy of 1864 was so relentless and so tightly coordinated that it could have confused the greatest commanders in history—not merely defeated the Confederacy, but baffled the best. That general was James Longstreet, who had fought against the very campaign he was praising.
He bled for it. He watched it grind down his own army until it vanished over five brutal weeks. So why would a man who despised what Grant’s strategy cost him return to describe it as one of the most dangerous military operational plans he had ever seen? Longstreet and Grant were not strangers when the war began.
They knew each other at West Point. More than that, Longstreet had served as an usher at Grant’s wedding in 1848, standing beside a man he would spend four years trying to defeat on some of the bloodiest ground in American history. Longstreet understood Grant’s temperament, his habits, and his way of solving problems in a way no other Confederate general could claim. When Longstreet later wrote about Grant’s strategy, he was not writing as a distant observer reading after-action reports.
He was writing as a man who had personally watched an old friend become the most effective military opponent the Confederacy ever faced. The strategy in question was not any single battle. It was the entire framework Grant built for 1864. It represented a complete break from how the Union had fought the war in its first three years.
Before Grant took overall command of Union armies in March 1864, the eastern and western theaters operated as almost separate wars, poorly coordinated at best. Confederate leaders exploited that separation repeatedly, shifting troops between theaters to reinforce whichever front needed them most, relying on the fact that Union armies rarely pressed multiple fronts simultaneously with enough strength to prevent such internal redeployment. Grant’s vision, simple to describe and enormously difficult to execute, was that the Confederacy’s ability to move resources between fronts was itself a weakness that could be closed if all Union armies advanced at the same time on all fronts with enough continuous pressure that no front could safely be stripped of troops. The Confederates would be forced to fight everywhere at once, with a force never large enough to fight everywhere in the first place.
That was the plan Grant put into motion in the spring of 1864. William Tecumseh Sherman would advance into Georgia toward Atlanta. Benjamin Butler would move up the James River toward Richmond from the southeast. Franz Sigel would move through the Shenandoah Valley, depriving the Confederacy of the agricultural breadbasket that had fed Lee’s army for years.
And Grant himself would move with the Army of the Potomac to press directly and continuously against Robert E. Lee’s army in northern Virginia, the Confederacy’s most capable and most symbolically important fighting force. Individually, none of these moves was tactically revolutionary. What made the plan dangerous, something Longstreet recognized and respected even while fighting it, was the simultaneity.
Lee could no longer count on Richmond sending reinforcements from a quiet western front, because there was no longer a quiet front anywhere in the Confederacy. Every theater was under simultaneous pressure, and every Confederate army was fighting its own battle for survival at the same moment Lee was fighting his. Longstreet felt the second, more personal dimension of this strategy directly. In the first week of May 1864, Grant crossed the Rapidan River and pushed the Army of the Potomac straight into the dense, tangled woodland known as the Wilderness.
It was the same terrain where Lee had won one of his most decisive victories a year earlier against Joseph Hooker. Longstreet’s corps, which had spent months in Tennessee, arrived in time to reinforce Lee’s line at the moment it was about to collapse, turning back a Union attack that nearly crushed the Confederate right flank. By any measure, it was a tactical victory for the Confederacy. Then something happened that had never happened before after any Confederate victory in the eastern theater.
Grant did not retreat. Every Union commander before Grant had responded to a bloody setback in Virginia the same way. McClellan withdrew after Antietam instead of pressing his advantage. Burnside retreated across the Rappahannock after the disaster at Fredericksburg.
Hooker withdrew across the same river after Chancellorsville, even though he still commanded a numerically superior army. The pattern was so consistent that Lee’s entire operational approach was built around it: inflict enough damage on any Union advance, and the Union army would withdraw to regroup, giving Lee time to rest and reposition his smaller force. On the night of May 7, 1864, after two days of savage fighting in the Wilderness that cost the Union about 17,000 casualties, Grant’s army began to move. Union soldiers who had fought and bled in that terrain assumed they were withdrawing as every Army of the Potomac had withdrawn before.
When the column turned south instead of north, toward Richmond and not away from it, the reaction among the ranks was something historians have consistently described in dozens of soldier accounts. Men who had never known a commanding general willing to keep advancing after a bloody engagement began cheering in the darkness, instantly understanding what moving south meant. Longstreet was likely thinking of this moment when he wrote his later assessment of Grant’s strategy. Because Longstreet himself was wounded a few days after the Wilderness, hit by friendly fire in circumstances hauntingly similar to the death of Stonewall Jackson exactly a year earlier.
He spent the following months recovering while reading reports of a campaign that refused to follow any pattern the Confederacy had learned to exploit. From a hospital bed and then during a slow convalescence away from the front, Longstreet watched Grant do what no previous Union commander in the East had proven able to do. He absorbed heavy losses without stopping, treated every tactical setback as a temporary cost rather than a reason to withdraw, and maintained constant pressure on Lee’s army to such a degree that the Army of Northern Virginia never again received the rest and reorganization it had relied on throughout the first three years of the war. There is a specific word in Longstreet’s original assessment that deserves close attention.
The word he chose was “baffle,” not defeat, not crush, not numerical superiority. Baffle means confusion—a strategy so multi-layered and so difficult to counter that even a skilled opponent would struggle to identify an appropriate response. That choice of word reflects something specific that made Grant’s approach so hard for Confederate commanders to counter tactically, even when they won individual engagements. At Spotsylvania Court House, fought less than two weeks after the Wilderness, Lee’s army inflicted heavy losses on attacking Union forces during nearly twenty hours of continuous close-range fighting at a salient known as the Bloody Angle, where fighting raged so intensely that an oak tree more than twenty inches thick was completely cut through by rifle fire alone.
Lee held the field. Instead of treating that defensive success as a reason to withdraw, Grant simply extended his line southward and kept moving, forcing Lee to match every change with a corresponding move by his increasingly exhausted army. This was the specific mechanism that made Grant’s campaign so difficult to counter with traditional Confederate tactics. Lee’s entire strategic playbook throughout the war depended on decisively defeating the Union army in a single battle, so that it would need weeks or months to recover before threatening Richmond again.
That playbook assumed Union commanders who treated heavy casualties as a signal to stop. Grant shattered that assumption completely. Every individual battle in the Overland Campaign—the Wilderness, Spotsylvania, North Anna, Cold Harbor—can be analyzed on its own tactical merits, and Confederate forces often came out ahead in those individual analyses. But Grant was not fighting for individual tactical victories.
He was waging a campaign designed around an entirely different kind of calculation. The Union could replace its losses thanks to a larger population and an effective conscription system. The Confederacy, bleeding at a similar or even lower rate in many of these battles, could not replace its losses at anything close to that pace. Every battle that ended without a decisive Confederate victory, even the ones Lee technically won on the field, still moved the overall calculus of the war in Grant’s favor.
That calculus is exactly what Longstreet meant when he said this strategy could baffle the best generals in history. It describes a form of warfare that makes traditional battlefield brilliance almost irrelevant. A general who wins every individual engagement can still lose the campaign if his opponent has correctly calculated that individual engagements no longer determine the outcome. Robert E.
Lee, by near-universal historical consensus, was one of the most talented tactical commanders the United States ever produced. A man who spent two years outmaneuvering Union generals through offensive maneuvers and careful reading of enemy psychology. Grant’s strategy did not try to outmaneuver Lee tactically the way McClellan or Hooker had tried and failed. It simply made tactical brilliance insufficient by changing what victory actually required.
By mid-June 1864, after nearly five weeks of continuous fighting that cost both armies together between 90,000 and 100,000 casualties, Grant moved his army across the James River and settled into a siege of Petersburg, the railroad center that supplied Richmond from the south. Lee’s army, which had fought with tremendous skill and inflicted disproportionate losses on Grant’s forces throughout the campaign, was nevertheless smaller, hungrier, and less able to replace its losses than it had been in May. The siege that followed lasted nine long months. Over those nine months, Lee’s army steadily deteriorated in ways that no victory in any single battle, however skillfully achieved, could have reversed.
Because the strategic framework Grant had established meant Confederate resources everywhere else in the country were under similar pressure, with no reserve of men or materiel available to replace what Petersburg was slowly consuming. Sherman’s simultaneous campaign in Georgia showed how the coordinated pressure Longstreet described worked in practice rather than merely as strategic theory. While Grant besieged Lee at Petersburg, Sherman advanced toward Atlanta against Joseph Johnston and then John Bell Hood. Crucially, Lee could not send significant reinforcements to help defend Georgia without weakening his already strained lines against Grant.
The Confederacy found itself for the first time in the war genuinely unable to concentrate force at the point of greatest danger, because every point had become a danger at once. Atlanta fell in September 1864, a result that reshaped the entire political landscape of the Northern war effort and secured Lincoln’s reelection in November of that year. Atlanta’s fall was possible only because Grant’s strategy in Virginia succeeded in denying Lee the flexibility to respond to it. Longstreet’s postwar writings on all this carry special weight because of what happened to him personally after the war ended.
Unlike most of his former colleagues, Longstreet maintained a genuine friendship with Grant after the war. He accepted a position in the Republican administration Grant led as president, supported Reconstruction policies that were profoundly unpopular among former Confederates, and as a result became an outcast within the community of former Confederate officers who spent the postwar decades building what historians now call the Lost Cause narrative of the war—an interpretation that downplayed Union strategic and tactical skill in favor of a story about Confederate courage overcome only by material superiority. Longstreet was not a man inclined to flatter Grant for political reasons or personal loyalty at the expense of military integrity. His writings elsewhere are full of sharp, sometimes bitter criticism of specific Confederate decisions, including decisions made by Lee himself.
When Longstreet praised Grant’s strategic thinking, he was doing so as a professional soldier, offering a professional judgment that directly opposed the narrative most of his former peers were constructing at the moment he was writing. The willingness to say something honest and unpopular rather than something comfortable and expected is part of what makes this assessment worth taking seriously more than 150 years later. Understanding what Longstreet was not saying also helps, because the statement has sometimes been misread as wholesale praise for Grant’s tactical genius on the battlefield. That is not exactly what Longstreet meant.
Grant was not, by most contemporary and modern assessments, tactically superior to Lee in the narrow sense of battlefield maneuver and troop positioning. Many of the individual engagements within the Overland Campaign, judged on purely tactical terms, tilted significantly toward the Confederacy. Grant himself acknowledged in his memoirs that certain decisions, most notably Cold Harbor, were outright mistakes he regretted for the rest of his life. What Longstreet was identifying was something on an entirely different level of military thinking: not the tactical skill to win individual battles, but the strategic clarity to understand which battles actually needed to be won, and the discipline to accept short-term tactical losses in service of a long-term strategic framework for which Confederate commanders had no effective response.
The concept Grant effectively pioneered—denying the enemy the ability to concentrate its strength by exercising coordinated pressure on every available front simultaneously—became a foundational principle of modern warfare, a concept that reappeared in strategic thinking during both world wars and after. Grant was not working from any established doctrine when he devised this plan in the winter of 1863 and early 1864. He was working from a cold assessment of Union advantages in manpower and industrial capacity, and a recognition that those advantages had never been fully exploited because Union armies had been fighting separate, uncoordinated wars against a Confederacy that always outmaneuvered them through internal flexibility. Longstreet, from his unusual position as someone who fought against that strategy and suffered from it personally, yet retained enough intellectual integrity to describe it accurately, gave history one of the clearest contemporary assessments of what actually distinguished Grant from every Union general who preceded him.
It was not battlefield genius in the traditional sense that Civil War history celebrates. It was not tactical brilliance capable of outmaneuvering Lee on his own preferred terms and terrain. It was something rarer and ultimately far more decisive: the strategic clarity to see the entire war as one interconnected system rather than a series of separate engagements fought in isolation, and the discipline to execute that vision completely even when every individual battle along the way appeared to be going against him. That is what Longstreet meant when he said it could baffle the best generals in history.
He watched it baffle Robert E. Lee.
