On the night of February 25, 1855, William Poole stood at the bar of Stanwix Hall on Broadway. The saloon was half empty, lit by low gas lamps. The men still drinking were not respectable. They were killers and political fixers.
Poole was the biggest man in the room. At 6 feet tall and over 200 pounds, he dominated any space he entered. In an era when the average man stood 5'7", Poole filled a doorway just by walking through it. His hands, trained since childhood to break down animal carcasses, were wrapped around a glass of brandy.
He did not know that Louis Baker had just walked through the front door behind him. He did not know Baker carried a Colt revolver under his coat. He did not know that in the next three minutes he would be shot three times, and that it would take him 11 days to die.
A bullet lodged in his abdomen. No anesthesia, no antibiotics, no surgery. The doctors decided that cutting him open would kill him faster than leaving the bullet in. For 11 days, the most dangerous man in New York City lay in a bed and rotted from the inside out.
History has tried to bury what happened next. His famous last words, "Goodbye, boys. I die a true American," may never have been spoken at all. One witness said he was delirious. Another said he was cursing. A third said he whispered something no one could hear.
The version that survived was the one the politicians needed. The "true American" line was too perfect, too useful. That should make you suspicious.
When Martin Scorsese made Gangs of New York, audiences assumed Hollywood had exaggerated Daniel Day-Lewis's terrifying villain. They had not. They had actually toned Bill the Butcher down. The real William Poole was worse.
The Five Points in 1850s Manhattan did not look like a neighborhood. It looked like something that happened to a neighborhood. Five streets converged in Lower Manhattan, and at their intersection was a permanent human catastrophe. Charles Dickens walked these streets in 1842 and described hideous tenements that took their name from robbery and murder.
Over 290,000 people lived per square mile in some blocks. The air smelled of sewage and coal smoke. The streets ran with filth after every rain. Every block belonged to someone.
To the east, the Bowery belonged to the nativists, the Bowery Boys. They were American-born, Protestant, and certain that the waves of Irish and German immigrants were destroying their city. To the west, the Five Points belonged to the Irish gangs, the Dead Rabbits, the Plug Uglies, the Shirt Tails.
In the middle of it, working a butcher's stall at the Washington Market, was William Poole. He was 33 years old, born in Sussex County, New Jersey, to a family of butchers. His father held a stall at the same market before him. Bill could break down a hog carcass by the time he was 10.
The trade taught him anatomy. Where the joints give. Where the blade slides easiest. Where a body comes apart if you know what you are doing. He brought this knowledge to every fight he ever had.
The Irish had their own story. Many had arrived as children during the Great Famine, packed into coffin ships where one in five passengers died before ever seeing land. They stepped onto Manhattan's docks with nothing. Shop windows read "No Irish need apply," and they were not metaphorical.
Bill Poole did not become Bill the Butcher because of his day job. He earned it in bare-knuckle boxing. Poole was undefeated. He fought with a devastating right hand and an absolute indifference to rules. Gouging, biting, and breaking were not violations in the Points. They were techniques.
Poole once bit off a man's ear during a fight. He reportedly carved a rival's face with a butcher's cleaver outside a saloon on Elizabeth Street. He was arrested multiple times. He was never convicted because no witness would testify.
"I can lick any man in this room." That was his opening line, delivered to every bar he ever walked into. He was almost always right.
Poole was a core member of the Bowery Boys, a nativist gang that could muster 200 to 300 core fighters. He was also a volunteer firefighter with Engine Company 34. In 1850s New York, volunteer fire companies were not about putting out fires. They were political gangs with fire engines. When a building caught fire, rival companies would race to the scene, not to save the building, but to fight each other for the right to put it out.
On the other side stood the Dead Rabbits, who marched behind a dead rabbit impaled on a pike as their battle standard. They were Irish Catholic, fiercely loyal, and they answered to Tammany Hall, the Democratic political machine that traded votes for jobs and protection.
And then there was John Morrissey. Born February 12th, 1831, in Templemore, County Tipperary, Ireland. He arrived in America as a toddler and grew up in Troy, New York, in grinding poverty. It did not crush him. It forged him.
As a young man in a Troy barroom, he was knocked backward onto a red-hot coal stove during a fight. His shirt caught fire. His skin burned. He kept fighting. He won the fight while his flesh cooked. He walked out with a new name: Old Smoke.
By 1853, Morrissey was the heavyweight boxing champion of America, having defeated Yankee Sullivan in 37 brutal rounds. 37 rounds of bare-knuckle boxing. No gloves, no time limits, no mercy. Tammany Hall owned him. They pointed him at their enemies like a weapon.
In 1854, the Know Nothing Party had exploded onto the national stage. They were nativist, anti-Catholic. In a single election cycle they captured 52 congressional seats. Their platform was simple. America for Americans. Catholics, especially Irish Catholics, were agents of the Pope and could never be loyal citizens.
The Know-Nothings got their name because when asked about their organization, members were instructed to say, "I know nothing." It was a security protocol. They operated as a secret society with lodges, passwords, and initiation rituals.
Bill Poole was not just a gang leader. He was a political soldier in a secret war for the soul of American identity.
Sometime in late 1854, intermediaries from Tammany Hall reportedly approached Poole's circle with something resembling a truce. The Irish gangs would stay south of Canal Street. The Bowery Boys would hold the Bowery. Elections would still be violent, but there would be territory and limits.
Poole refused. He did not want peace. He wanted the Irish gone. By late 1854, he was openly boasting that he would personally destroy John Morrissey.
That opening came on a summer dock in 1854. July 1854, the wooden pilings of the Amos Street pier jut into the Hudson River. The crowd, maybe a hundred men, gathered in a loose ring on the dock's planking. This was William Poole versus John Morrissey, bare-knuckle for everything.
The fight was held on the docks because the docks were technically outside the jurisdiction of the city police. The New York Police Department had no authority on the waterfront. Gang leaders knew this. They scheduled their most violent confrontations on the piers.
Poole was bigger, faster, and meaner at close range. He drove Morrissey backward with combinations that split skin and cracked bone. Morrissey's face opened up. Blood sheeted down his chin. It was not close.
As Poole battered Morrissey toward defeat, the fight broke apart. Morrissey's seconds drew knives. The crowd erupted into a general brawl. Police finally arrived and scattered both factions. Morrissey was carried away, his face a ruin. Poole walked off the dock under his own power, barely marked.
When associates found Morrissey later that night nursing his wounds, he reportedly said three words: "This isn't over."

The place where it would happen was Stanwix Hall, a saloon at 207 Broadway. Not a Five Points dive. A respectable establishment. Gas-lit chandeliers, dark wood paneling, sawdust on the floor. A place where politicians and gang leaders drank at the same bar, because in this city, those were often the same people.
The night of February 24th, 1855. Poole is at Stanwix Hall with several associates. They have been drinking for hours. Sometime after midnight, three men walk through the front door. Louis Baker, Paudeen McLaughlin, James Turner. Baker is a Morrissey loyalist. He is carrying a Colt revolver under his coat.
Words are exchanged. The temperature in the room rises in seconds. Poole is standing at the bar when Baker pulls the Colt.
Baker fires. The first bullet hits Poole in the left leg, just above the knee. Poole does not go down. He lunges forward. Baker fires again. The second bullet strikes Poole in the chest, left side. The third, the one that will kill him, enters his abdomen.
Poole staggers. His legs fail. He crashes against the bar and slides to the sawdust floor. From Baker walking through the door to Poole hitting the floor, less than 60 seconds.
A physician arrives within the hour. The abdominal wound is catastrophic. The bullet has penetrated the peritoneum. In 1855, there is no antiseptic surgery. There are no antibiotics. Opening the abdomen to retrieve the bullet will almost certainly kill him faster than leaving it in. The bullet stays.
Poole is carried to a room nearby. The vigil begins immediately. Bowery Boys stand guard at the door. By dawn on February 25th, the shooting is the only story in New York. The Know-Nothings claim Tammany Hall ordered the hit. Tammany denies it. Morrissey, conspicuously, was not at Stanwix Hall that night. He has an alibi. But his man, Baker, pulled the trigger.
For the first three days, there is hope. Poole is conscious. He speaks. He is furious, demanding revenge, cursing Morrissey's name. But by day four, the fever sets in. Peritonitis is spreading. His abdomen swells. The pain becomes a constant living thing inside him.
While Poole suffers, the Know-Nothing movement mobilizes. Rallies are held. Poole's name becomes a slogan. "Remember Bill Poole" appears on walls, on handbills, on banners. He is not yet dead and he is already being transformed from a violent gang leader into a martyr.
On the morning of March 8th, 1855, 11 days after the shooting, William Poole begins to die. His breathing becomes shallow. His eyes, when they open, are unfocused.
The famous version: Poole looked at the men around him and said, "Goodbye, boys. I die a true American." Six words. Clean. Perfect. A political slogan delivered from a deathbed.
The Know-Nothings printed those words on banners within hours. They appeared in newspapers the next morning. They were chanted at rallies for months. They were carved onto his headstone.
But multiple witnesses gave different accounts. One man present said Poole was incoherent in his final hours, mumbling delirious. Another claimed he cursed Morrissey with his dying breath. A third said he whispered something no one in the room could make out.
The "true American" line is suspiciously perfect. Six words that just happened to be the ideal Know-Nothing recruitment slogan. Whether Poole said them or whether a political operative put them in his dead mouth, history cannot say for certain.
William Poole died on the morning of March 8th, 1855. He was 33 years old. He had survived bare-knuckle brawls, knife fights, cleaver attacks, and a lifetime of violence. He was killed by a bullet and 11 days of sepsis.
Louis Baker vanished. He fled New York within hours of the shooting and eventually surfaced in the Canary Islands. McLaughlin and Turner were also in the wind. Morrissey, untouchable behind his Tammany allies, denied any involvement.
The Know-Nothing leadership took control of the funeral arrangements. This would be a political demonstration. On the appointed day, they came. Estimates range from 5,000 to 6,000 marchers, the largest funeral procession in New York City history to that date. The line stretched over a mile through lower Manhattan.
Poole's coffin was carried on a horse-drawn hearse draped in American flags. Every marcher wore a black crepe armband. Many carried signs bearing those six famous words.
To understand how extraordinary this funeral was: 5 to 6,000 marchers in a city of roughly 630,000 people. Approximately one in every 100 residents of New York City marched in the funeral of a gang leader who had never held public office, never served in the military, and never done anything more civic-minded than join a volunteer fire company that existed primarily to brawl with other fire companies.
The procession ended at Greenwood Cemetery in Brooklyn. His headstone at Greenwood still stands today. The New York Tribune reported, "Such a demonstration has never been witnessed in this city."
The Know-Nothings converted Poole's death into an immediate political weapon. "Avenge Bill Poole. Americans must rule America." The rally cry echoed through nativist meetings from New York to Philadelphia to Baltimore. Membership in Know-Nothing lodges spiked. Catholic churches in several cities received threats.
Lewis Baker was eventually extradited from the Canary Islands and brought back to New York to stand trial for Poole's murder. He was tried three times. The first trial, mistrial. The second trial, mistrial. The third trial, acquittal.
No one was ever punished for the murder of William Poole. Not Baker, not McLaughlin, not Turner, and certainly not John Morrissey, who was never charged at all.
Did Morrissey order the killing? The evidence is circumstantial, but heavy. Baker was his man. The confrontation at Stanwix Hall followed months of escalating tension that traced directly back to Morrissey's humiliation at Amos Street. But no direct order was ever proven. No confession was ever extracted.
Two years after Poole's death, the war he helped start reached its climax. On July 4th, 1857, the Dead Rabbits and Bowery Boys fought the largest gang battle in New York City history across the streets of the Five Points and the Bowery. Eight men died. Over 100 were wounded. The National Guard was called in to restore order.
John Morrissey went legitimate. He founded the Saratoga Race Course, the racetrack that still operates today. He was elected to the New York State Senate. He served in the United States Congress. The former heavyweight champion, the Tammany enforcer, became a respected American politician.
Years later, he reportedly said of Poole, "He was the best man I ever fought."
The Know-Nothings did not survive the decade. They split over slavery and collapsed by 1860, consumed by the same sectional crisis that was about to tear the entire nation apart in the Civil War. Poole's martyrdom was their last great propaganda victory. It was not enough.
Martin Scorsese's Bill the Butcher, played by Daniel Day-Lewis, is toned down from the real William Poole. The film gave Bill the Butcher a code of honor, a twisted one, but a code. The real Poole had no code. He bit, gouged, carved, and terrorized with no philosophical framework whatsoever.
The Five Points no longer exists. It was demolished. In 1893, the city tore down the worst of the tenements and built a park. Later, they built the New York County Courthouse over the exact intersection where five streets once met. If you walk to 60 Centre Street in Manhattan today, you will stand in a marble lobby surrounded by lawyers and judges. Beneath your feet, under the foundation, are the remains of the most violent neighborhood in American history.
William Poole was not a hero. He was not a patriot. He was a violent, bigoted man who lived by the fist and died by the bullet. And the fact that his death mattered more than his life tells you everything you need to know about how America makes its myths.
