In the winter of 1864, Robert E. Lee put his pen to paper and wrote something he almost never allowed himself to write. Lee was a man of careful words, a West Point graduate who had served the United States Army for more than three decades before the country tore itself apart. But in that letter, now sitting in the archives of the Virginia Historical Society, he let his composure slip.
He wrote about a Union general, not Grant and not Meade, but a red-haired, restless, hollow-eyed man from Ohio who had not yet become famous. The name was Sherman. What Lee saw coming, the rest of the country has spent 160 years trying to categorize. Was Sherman a hero?
A war criminal? A military genius? A madman? Lee understood that William Tecumseh Sherman was not simply a general who won battles.
He was the architect of a new kind of destruction, one that did not target armies. It targeted the will of an entire people to keep fighting. Sherman was born in 1820 in Lancaster, Ohio, the sixth of eleven children. His father died when he was nine, and the family was scattered.
He was taken in by a neighbor, Thomas Ewing, a powerful Ohio senator who later became Secretary of the Treasury. It was Ewing who secured Sherman’s appointment to West Point. There, Sherman absorbed Jomini’s theories on massed force, the Napoleonic principles of rapid movement, and an older, grimmer understanding that wars end not when armies are destroyed, but when populations lose the stomach to replace them. He graduated sixth in his class in 1840, was commissioned into the artillery, and served in Florida during the Second Seminole War.
He was posted to various southern garrisons, spent time in Charleston and in Georgia. He liked the South. He had friends there. He understood its rhythms, its vanities, its particular brand of pride.
This was not a small detail. It would later make him more dangerous to the South than any general who saw it as simply foreign territory. He resigned his commission in 1853, tried banking in San Francisco, failed, tried law in Kansas, failed, then went to Louisiana and became superintendent of what would later become Louisiana State University. He was genuinely admired there.
Then the war began. His first real engagement was at Bull Run in July 1861, and it was a disaster for the entire Union. Confederate forces broke the federal lines and sent soldiers running back toward Washington in scenes of chaos that shocked the northern public, which had expected the rebellion to collapse in weeks. Sherman handled his brigade adequately, but he was shaken.
He wrote to his wife that the war would be long, much longer than anyone in Washington was willing to admit, and that the politicians directing it had no real concept of what they were dealing with. He was right, and it would cost him. He was transferred to Kentucky and given command of the Department of the Cumberland. There, under the pressure of command, the inadequacy of his resources, and his growing conviction that the Union was losing, he fell into a state of anxiety so severe that newspapers began calling him insane.
He was relieved of command. He went home to his wife, Ellen, and for a time disappeared from the war entirely. Ulysses Grant brought him back. Grant had met Sherman early in the war and recognized something the newspaper editors and Washington politicians missed entirely: Sherman’s anxiety was not weakness, but the correct response to a situation everyone else was misreading as simple.
At Shiloh in April 1862, everything changed. Confederate forces under Albert Sidney Johnston launched a surprise attack on the Union encampment on the morning of April 6 and came close to driving Grant’s entire army into the Tennessee River. The fighting was close, brutal, and grinding, without the clean lines and heroic charges people had imagined war would look like. Sherman was everywhere that day.
He had two horses shot out from under him, was wounded in the hand, and refused to leave the field. When the battle ended two days later with Union forces driving the Confederates back, Sherman had demonstrated something that would define the rest of his career: he did not break under pressure. Grant promoted him, and their partnership became the spine of the Union war effort in the Western theater. Together they took Vicksburg in July 1863, splitting the Confederacy along the Mississippi and cutting off the Trans-Mississippi states from the rest of the South.
It was after Vicksburg that Sherman began to talk openly about the ideas Lee was picking up on even from across the lines. In letters, dispatches, and conversations with other officers, he argued that the Confederate civilian population was as much a part of the war as its armies. Southern planters, merchants, politicians, and ordinary white families who supported the rebellion were not innocent bystanders. The war could not be ended by simply defeating Confederate armies in the field, because the South had enough land, determination, and hatred of the North to raise new armies indefinitely.
The only way to end it, he argued, was to make the population of the South feel the war in a way they had not yet felt it. He called it hard war. Robert E. Lee had been watching the Western theater carefully.
Stretched thin holding the Army of Northern Virginia against Grant and Meade, scraping together men and supplies the Confederacy was running out of, he still saw what was developing in Sherman and it troubled him in a way conventional military threats did not. Lee understood traditional warfare completely; he could read an army’s movements the way a musician reads sheet music. What he could not counter was a general who had decided to stop fighting the Confederate Army and start fighting the Confederate idea. In private correspondence and in communications with Jefferson Davis, he flagged Sherman’s approach as something qualitatively different.
He was not warning about Sherman’s battlefield tactics. He was warning about Sherman’s philosophy. In the fall of 1864, that philosophy was demonstrated on a scale no one, not even Lee, had fully anticipated. Atlanta fell to Sherman on September 2, 1864.
Atlanta was the industrial and railroad heart of the deep South, and its capture came when northern morale was at its lowest point of the war, when Lincoln himself believed he would lose the November election. Sherman’s capture of Atlanta saved Lincoln’s presidency. But what Sherman did next is what history remembers and argues about. He ordered the evacuation of the civilian population of Atlanta, every man, woman, and child, intending to use the city as a military base.
When the mayor and two Confederate generals protested on humanitarian grounds, Sherman wrote back one of the most remarkable documents in American military history. He told them they were correct: it would cause suffering, and the Confederate leadership bore responsibility because they had started a war. War was cruelty, and it could not be refined. The sooner the South understood this, the sooner the war would end.
Then he burned Atlanta’s industrial and military infrastructure, left the ruins behind him, and turned his army south. Sixty thousand Union soldiers moved through Georgia in a column sixty miles wide. They destroyed railroads by heating the rails and bending them around trees, what soldiers called Sherman’s neckties. They burned cotton gins, warehouses, granaries, and mills.
They consumed or destroyed the livestock and food stores of every plantation and farm in their path. They did not, as a systematic matter of official policy, burn civilian homes, though individual soldiers did and Sherman’s discipline over his army was imperfect at best. What they systematically destroyed was the economic infrastructure that supported the Confederate war effort: the plantations that fed the armies, the railroads that moved supplies, the mills that processed the cotton that financed the rebellion. The Confederate forces in Georgia, under General John Bell Hood, had chased after Grant in Tennessee, leaving Sherman’s path essentially uncontested.
Reports came out of Georgia of plantations stripped bare, of enslaved people walking away from their bondage by the thousands to follow the Union columns, of families writing to their sons in the Confederate Army telling them to come home because there was nothing left. These reports did to Confederate morale what no battlefield defeat had managed. They made the war feel lost. That was the point.
Sherman reached Savannah on December 21, 1864, and sent Lincoln a telegram offering him the city as a Christmas present. Then he turned north. The march through South Carolina was worse than Georgia by most accounts. South Carolina was where the war had begun, where secession had started, where Fort Sumter had been fired on, and Sherman’s soldiers carried a particular fury into it.
Columbia, the state capital, burned on the night of February 17, 1865. The question of who burned it, Sherman’s soldiers, retreating Confederates, drunken stragglers from both sides, a fire started by loose cotton bales, has been argued about ever since. Sherman denied ordering it. What is not disputed is that much of the city burned and that Sherman did not try very hard to stop it.
By the time he reached North Carolina in March 1865, the Confederate position had become exactly what Lee had warned it would become. Grant pressed the Army of Northern Virginia from the north. Sherman pressed from the south. Lee’s army was exhausted, undersupplied, outnumbered, and shrinking daily as soldiers deserted and went home to families in Georgia and South Carolina who had written that the Yankees had already been there and there was nothing left to defend.
Lee surrendered to Grant at Appomattox on April 9, 1865. The arguments began almost immediately and have not stopped. In the South, Sherman became a villain of nearly mythological proportion. Families who lived through the march passed down stories of destruction and loss for generations, shaping how the Civil War was remembered below the Mason-Dixon Line: not primarily as a fight over slavery, but as an invasion, an occupation, a brutal imposition of northern will on southern civilization.
In the North, Sherman was a hero, his portrait hung in public buildings, his name given to towns and counties, volumes written celebrating his military genius and his refusal to sentimentalize a war that required ruthlessness to end. The march did shorten the war, demoralizing the Confederate population and contributing to Lee’s decision to surrender. The question neither side has fully answered is whether the goal alone justifies the method, and whether the precedent Sherman established of making civilian populations deliberate targets of organized military destruction was a gift or a curse to the history of warfare that followed. Military historians have traced a direct line from Sherman’s concept of hard war to the strategic bombing campaigns of the Second World War, to the firebombing of Dresden and Tokyo, to the doctrine of total war that defined the twentieth century’s most catastrophic conflicts.
Sherman himself argued in his memoirs that making war terrible was the most humane approach because a terrible war ends quickly, while a gentle war drags on and kills more people in the aggregate. Lee’s warning, read carefully, was not simply a tactical assessment of a dangerous Union general. It was a recognition that Sherman represented a threshold being crossed, that the Civil War was producing a new kind of warfare the old rules, the old codes of conduct, the old understanding of what soldiers could and could not do to civilian populations were not equipped to contain. Lee was a man of the nineteenth century.
He did not make war on civilian populations. He did not systematically destroy the economic infrastructure of the Northern states when he invaded Maryland and Pennsylvania. Sherman disabused him of the belief that the other side would observe similar constraints, and in doing so, Sherman did not simply win a campaign. He changed the nature of war itself.
William Tecumseh Sherman died in New York City on February 14, 1891, at the age of 71. He had spent his last years writing his memoirs, giving speeches, watching the country he had helped hold together struggle with the consequences of what it had done to achieve that unity. At his funeral, former Confederate General Joseph Johnston, who had faced Sherman in Georgia and the Carolinas and surrendered to him in April 1865, insisted on serving as a pallbearer despite the cold weather. Friends urged him to put on his hat, but he refused, saying it would be disrespectful.
He stood bareheaded in the February cold as Sherman’s coffin passed, developed pneumonia shortly afterward, and died within the month. Johnston stood in the cold because he understood, as Lee had understood, what he was dealing with: not simply a general who had beaten him, but a man who had changed the nature of the fight itself. Lee died in 1870, more than twenty years before Sherman. But the warning he left in his letters and dispatches, that Sherman was something different, something the old categories of soldier and commander and warrior did not cover, has echoed through every military conflict since in which the line between combatant and civilian has been deliberately erased in the name of ending the war quickly.
He was right. That is the terrible thing. He was right and it did not save him, and it did not save the South, and it did not prevent the precedent from being set.
It only meant that someone, at least, had seen clearly what was coming and understood its consequences before they arrived.
