The American Old West was a wild tapestry of courage, conflict, and legendary figures whose tales still echo through time. Among the dusty trails and lawless towns, a select few gunslingers emerged as icons, their stories so gripping they feel almost too incredible to be true. Here are the top 15 deadliest gunslingers who left an indelible mark on Western history.
Starting with number 15, we have William Brochius, better known as Curly Bill. His unruly black curls were as famous as his larger-than-life persona in Tombstone, Arizona. After the death of old man Clanton, Curly Bill became a prominent figure among the cowboys, a group notorious for cattle theft and border raids.
He even dabbled in law enforcement, collecting taxes under Sheriff John Bean before his life took a tragic turn. In a fateful encounter with Marshall Fred White, a pistol discharged, resulting in White’s death. Although Curly Bill was acquitted, his fate was sealed months later when he crossed paths with Wyatt Earp, leading to his demise near Iron Springs.
At number 14 is Klay Allison, a man whose fiery temperament and unpredictable nature made him a notorious figure of the frontier. After serving in the Confederate Army, a head injury contributed to his erratic behavior. His life was filled with dramatic confrontations, including a famous incident with outlaw Chunk Colbert, where Allison’s quick thinking saved his life.
Despite his dangerous lifestyle, he met an unexpected end in 1887, falling from a wagon and breaking his neck. His gravestone reads, “Klay Allison, gentleman, gunfighter,” a testament to his complex legacy.
Number 13 is Sam Bass, whose journey began with noble intentions. After escaping an abusive uncle, he sought a better life as a cowboy in Texas. However, after a failed cattle drive, he turned to a life of crime, culminating in the infamous robbery of the Union Pacific gold train, netting over $60,000.
His short-lived career ended when he was wounded during a bank heist in Round Rock, Texas, passing away just two days shy of his 27th birthday.
Next up at number 12 is Jim Miller, known as Deacon Jim. His churchgoing demeanor hid a darker side, as he became one of the most feared hired guns of the Old West. Miller’s stealthy tactics and rumored 14 confirmed kills made him a notorious figure.
His life ended in a dramatic fashion when a mob hanged him in Oklahoma after he was accused of murder, leaving behind a haunting legacy.
At number 11, we meet the enigmatic Sundance Kid, born Henry Longabaugh. His infamous nickname came from a horse theft conviction in Sundance, Wyoming. Although often depicted as a dangerous gunslinger, there’s little evidence to support claims of him taking a life.
Instead, he was part of the notorious Wild Bunch gang alongside Butch Cassidy, engaging in a series of successful robberies before disappearing under mysterious circumstances in Bolivia.
Number 10 features Belle Starr, born Myra Maybel Shirley. With a background in refinement and education, she was drawn into a life of crime through her connections with notorious outlaws. After marrying Jim Reed, a former Confederate, she became a skilled planner of robberies.
Her life ended abruptly when she was shot from behind, leaving her legacy shrouded in mystery.
Bill Dulan comes in at number 9. Born in Arkansas, he worked as a cowboy before becoming an outlaw. Dulan led the Wild Bunch gang, robbing banks and trains across multiple states.
His life was cut short in 1896 when he was tracked down by law enforcement and killed, with his body displayed publicly, a grim reminder of his tumultuous life.
At number 8, we have Cherokee Bill, born Crawford Goldsby. He became infamous in the 1890s for his criminal exploits, which reportedly included multiple robberies and the deaths of eight men. After a swift trial, he was sentenced to hang at just 20 years old, leaving behind a legacy that continues to intrigue historians.
Number 7 is the legendary Doc Holliday. Born John Henry Holliday, he transitioned from dentist to gambler and became a close ally of Wyatt Earp. Although often credited with numerous kills, historians suggest the actual number is much lower.
His life culminated in the famous gunfight at the OK Corral, after which he continued to evade the law until his death from tuberculosis at just 36.
Tom Horn, at number 6, was born in 1860 and became a controversial figure known for his sharp shooting and complex legacy. He gained notoriety during the Lincoln County War and later worked for the Pinkerton Detective Agency. His life ended in execution for the murder of a young boy, a conviction that remains debated to this day.
At number 5, we find Butch Cassidy, born Robert Loy Parker. After a childhood spent learning from a mentor, he became a notorious outlaw and leader of the Wild Bunch gang. His life of crime was marked by daring robberies and a mysterious disappearance in Bolivia, leaving many to wonder if he ever truly met his end.
Thomas Coleman Younger ranks at number 4. After a tragic family loss, he joined the Confederate Army and later became part of the infamous James Younger Gang. His criminal career ended with a failed bank robbery, leading to a life sentence.
After his release, he sought redemption, sharing tales of his past until his death in 1916.
Billy the Kid, a name synonymous with the Wild West, holds the number 3 spot. Often romanticized, his life was more complex than the myths suggest. While he was involved in the Lincoln County War, the true count of his kills is believed to be much lower than the legendary 21.
His life ended in 1881 at the hands of Sheriff Pat Garrett, but his legend continues to captivate audiences.
Jesse James, born in 1847, is the second most iconic figure on our list. A product of the Civil War, he became a notorious outlaw, leading the James Younger Gang in a series of high-profile robberies. His life was cut short in 1882 when he was betrayed and shot, marking the end of an era in the Old West.
Finally, at number 1 is John Wesley Harden, a man whose early life was marked by violence and conflict. Known for his quick temper, he became a notorious gunslinger and later a lawyer after serving time in prison. His life ended abruptly in El Paso, leaving behind a legacy that continues to spark debate and curiosity.
