The scale of the slaughter at Gettysburg is almost impossible to grasp. In three days of fighting, roughly 51,000 soldiers were killed, wounded, or went missing. That was nearly a third of everyone who took part. The small Pennsylvania town became a charnel house, where surgeons stacked amputated limbs in piles higher than the operating tables and burned them at dusk, and where dead horses were heaped and set alight because there were simply too many carcasses to bury.
We are taught that Gettysburg was the victory that saved the Union. Far less often discussed is what that victory cost, and what it revealed about how far a nation was willing to go in order to destroy itself. The battle began on July 1, 1863, when two vast armies collided across the fields, orchards, and wooded ridges surrounding Gettysburg. For three relentless days, the forces of Union General George Gordon Meade and Confederate General Robert E.
Lee fought with no restraint. When the guns finally went quiet, the price was staggering: about 28 percent of Meade’s Army of the Potomac and more than 37 percent of Lee’s Army of Northern Virginia had been killed, wounded, or captured. In total, an estimated 64,000 men on both sides were casualties by the end of the campaign. No other battle on the American continent had ever matched its ferocity.
In the aftermath, the landscape was a horror. Bodies lay where they had fallen, and burial parties worked frantically to put them in the ground. The cemetery caretaker’s wife, Elizabeth Thorn, was heavily pregnant at the time and is said to have dug more than a hundred graves herself. Among the dead recovered on Cemetery Ridge was a woman who had disguised herself to fight for the Confederacy.
Another woman, also fighting disguised as a man, reportedly lost her leg while charging up the same ridge. For miles around the town, every barn, church, and home became a makeshift hospital. The residents surrendered nearly everything they had to shelter the wounded and dying. Conditions were appalling.
Many men lay directly on soaked ground, their stumps resting in the mud, unclothed, filthy, starving, and delirious. Surgeons worked around the clock, overwhelmed and chronically undersupplied, amputating limb after limb. During one violent thunderstorm, wounded soldiers nearly drowned in their own camps. At one point, an operation was beginning roughly every ten minutes.
The wounds themselves were a product of the era’s weaponry. More than two-thirds of all gunshot wounds struck the arms or legs, and the slow, heavy Minié balls shattered bones and tore gaping exit wounds far larger than their points of entry. They carried dirt and fabric deep into the body, seeding the deadly infections that followed. One soldier, Private Jacob Henry Cole of the 57th New York Infantry, recalled being hit twice in quick succession: a bullet passed through his right arm, and then a shell exploded, killing two of his comrades and shattering his right leg.
He described the initial sensation as numbness, like striking his elbow, and remembered thinking a friend had struck him until he saw the blood. When his leg gave out and he fell, he realized he and his unit were surrounded. When damage was limited, surgeons removed bullets, debris, and bone fragments and packed the wound with lint. But when bones were crushed beyond repair, amputation was the only real chance of survival, offering the best hope of avoiding blood poisoning, gangrene, or streptococcal infection.
Sergeant Alexander Blake of the First Missouri Infantry wrote of being wounded in the left arm near Gettysburg and having it amputated the next day. Even under chloroform, he said, he knew little of what was happening; the pain afterward was severe, but he believed he was healing well. Wounds to the face were especially ghastly. Private Joseph Harvey, struck by shell fragments, described the sensation as feeling like the floodgates in his neck had burst.
Blood poured from him, and something loose rolled around in his mouth: part of his jaw, teeth and all. Captured by Confederate forces, he spent eleven days as a prisoner before being sent to a hospital in Alexandria, where surgeons removed portions of his jawbone. The damage left his saliva leaking from his cheek, caused facial paralysis, and partial deafness, and he died in December 1868 from unknown causes. Another soldier, Private Roland of the Fourth New York Heavy Artillery, had his lower jaw obliterated by a shell fragment, leaving his tongue hanging down his neck and robbing him of the ability to swallow or speak.
The primitive plastic surgery of the time offered slim hope, and though he survived, he was permanently changed. Yet for all the horror of bullets and shells, the greatest killer of the Civil War was not combat. It was disease. More soldiers died of dysentery, smallpox, malaria, and yellow fever than from wounds.
Camps were overcrowded and unsanitary, and infection spread with terrifying speed. At the start of the war, doctors had no knowledge of germ theory. They rarely washed their hands and seldom sterilized instruments between surgeries, so infection was rampant, and death frequently came days after the fighting ended. Hospital gangrene was the most feared of all.
It devoured flesh, turned skin gray, and released a stench so foul that the airing out of hospitals, meant to reduce bacteria, sometimes made things worse when windows faced sewage pits. Gettysburg also claimed more generals than any other battle of the war. The Confederacy lost Generals Semmes, Barksdale, Armistead, Garnett, Pender, and Pettigrew during the retreat. The Union lost Reynolds, Zook, Weed, Farnsworth, and Vincent, who was promoted posthumously.
Among the wounded Confederate officers were Major General John Bell Hood, shot in the head and permanently paralyzed in one arm, and Major General Henry Heth, also struck in the head but saved by a hat stuffed with paper dispatches that deflected the bullet. The survivors carried more than scars. Many endured what we now recognize as post-traumatic stress disorder, then dismissed as nostalgia or homesickness. Others sank into morphine addiction, as pain relief was administered freely and often without restraint.
Some wounded men, unable to work or provide for their families, faced deep shame and despair, while the public’s uneasy reaction to their disfigurements only deepened their isolation. Even the animals paid a terrible price. Roughly five thousand horses and mules died at Gettysburg, and their bodies were later burned in massive piles. The stench of decay hung over the countryside for weeks, sickening the townspeople who had no way to escape it.
The guns finally fell silent at Gettysburg, but the cries did not. Fifty-one thousand men were gone, and yet it was called a victory. The Union stood, but at a cost that would be paid for generations. Families were torn apart, bodies left unrecognizable, and the town itself was forever haunted by what its soil had absorbed.
The Union was preserved, but the blood required to save it raised a question that would linger long after the battlefields grew quiet: whether any nation can survive so much sacrifice without shattering something inside itself.
