In the years after the Civil War, a Confederate general wrote something no other southern officer was willing to put on paper. He said that Ulysses Grant’s 1864 strategy was so relentless, so tightly coordinated, that it could have baffled the greatest commanders in history. The general was James Longstreet, who fought against that very campaign, bled because of it, and watched it grind his own army down over five brutal weeks. So why would a man who despised what Grant’s strategy cost him come back 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 from West Point. Longstreet had even served as a groomsman 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 thinking through 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 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 almost as separate wars, loosely coordinated at best. Confederate leaders exploited that division repeatedly, shifting troops between theaters to reinforce whichever front needed them most, relying on the fact that Union armies rarely pressed multiple fronts at once with enough force to prevent that kind of interior movement. Grant’s vision, simple to describe and extremely difficult to execute, was that the Confederacy’s ability to move resources between fronts was itself a weakness that could be closed if every Union army advanced at the same time on every front with enough sustained pressure that none of them could safely be stripped of troops.
The Confederates would be forced to fight everywhere at once, with forces not large enough to fight everywhere at all. 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, denying the Confederacy the agricultural breadbasket that had fed Lee’s army for years. And Grant himself would move with the Army of the Potomac to press Robert E. Lee’s army directly and continuously in northern Virginia, the Confederacy’s most capable and most symbolically important fighting force. Individually, none of these movements was tactically revolutionary.
What made the plan dangerous, something Longstreet recognized and respected even while fighting it, was the simultaneity. Lee could no longer rely 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 synchronized 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 directly into the dense, tangled woods known as the Wilderness, 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, repulsing a Union assault that nearly crushed the Confederate right entirely. By any measure it was a tactical victory for the Confederacy. Then something happened that had never happened 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 retreat to regroup, giving Lee time to rest and reposition his smaller forces. On the night of May 7, 1864, after two days of savage fighting in the Wilderness that cost the Union about seventeen thousand casualties, Grant’s army began to move.
Union soldiers who had fought and bled in that terrain assumed they were retreating as every Army of the Potomac had retreated before. When the column turned south instead of north, toward Richmond rather than away from it, the reaction among the ranks was something historians have consistently described. Men who had never had a commanding general willing to continue the advance after a bloody engagement began cheering in the darkness, immediately understanding what moving south meant. This was likely the moment Longstreet was thinking of when he wrote his later assessment of Grant’s strategy.
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 was accustomed to exploiting. From his hospital bed and through a slow recovery away from the front, Longstreet watched Grant do what no previous Union commander in the East had been able to do. He absorbed terrible losses without stopping, treated every tactical setback as a temporary cost rather than a reason to withdraw, and maintained pressure on Lee’s army so continuously that the Army of Northern Virginia never again received the period of rest and reorganization it had depended on throughout the first three years of the war.
One specific word in Longstreet’s original assessment deserves close attention, because the word he chose was baffle, not defeat, not crush, not numerical superiority. Baffle means confusion, a strategy so layered and so difficult to counter that even a skilled opponent would struggle to identify an appropriate response. That word choice reflects something specific that made Grant’s approach so difficult 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 fighting at close range at a salient known as the Bloody Angle, where fighting was so intense that an oak tree over twenty inches thick was cut entirely 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 south and kept moving, forcing Lee to match every change with a corresponding move by his increasingly exhausted army. Lee’s strategic playbook throughout the war had relied 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 terms, and Confederate forces often excelled in those individual analyses. But Grant was not fighting for individual tactical victories. He was fighting a campaign designed around a completely 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 battles Lee technically won in the field, moved the overall arithmetic of the war in Grant’s favor. That arithmetic is exactly what Longstreet meant when he said this strategy could baffle the best generals in history.
It describes a form of war in which traditional battlefield brilliance becomes almost irrelevant. A general who wins every individual engagement could still lose the campaign if his opponent had calculated precisely that individual engagements no longer determined the outcome. Robert Lee, by near-universal historical consensus, was one of the most gifted tactical commanders America ever produced. 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 ninety thousand and one hundred thousand casualties, Grant moved his army across the James River and settled into a siege of Petersburg, the railroad center supplying Richmond from the south. Lee’s army, which had fought with immense 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 deteriorated steadily in ways no victory in any single battle, however skilled, could reverse. Because Grant’s strategic framework meant Confederate resources everywhere else in the country were under similar pressure, with no reserve of men or matériel 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 point of danger at once. Atlanta fell in September 1864, a result that reshaped the entire political landscape of the Union war effort and secured Lincoln’s reelection that November. The fall of Atlanta 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. He accepted a position in the Republican administration Grant led as president and supported Reconstruction policies deeply unpopular among former Confederates. As a result, he became an outcast within the community of former Confederate officers who spent the postwar decades building what historians now call the Lost Cause narrative, an interpretation that minimized Union strategic and tactical skill in favor of a story about Confederate bravery 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. Understanding what Longstreet was not saying also matters, because his statement has sometimes been misread as sweeping praise for Grant’s tactical genius on the battlefield.
That is not quite what he meant. Grant, by most contemporary and modern assessments, was not 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 heavily 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 Confederate commanders had no effective answer to. There is a reason military academies still study Grant’s 1864 campaign today. The concept Grant effectively created, denying an opponent the ability to concentrate its strength by applying coordinated pressure on every available front simultaneously, became a fundamental principle of modern warfare, reappearing in strategic thought during the world wars and after.
Grant was not working from any established doctrine when he wrote this plan in the winter of 1863 and early 1864. He was working from a precise 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 confederation that always outmaneuvered them through its internal flexibility. Longstreet, from his unusual position as someone who fought against that strategy, suffered from it personally, and nevertheless retained enough intellectual integrity to describe it accurately, gave history one of the clearest contemporary assessments of what actually set Grant apart from every Union general who came before 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 terms and on his own 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.
