Who Really Shot Abraham Lincoln?

John Wilkes Booth was one of the most famous actors in America when he walked into Ford’s Theatre on the night of April 14, 1865. Born in 1838 into a celebrated theatrical family, Booth was a passionate Confederate sympathizer who had spent months plotting against President Abraham Lincoln. He originally planned to kidnap Lincoln and use him as a bargaining chip to free Confederate prisoners of war. When the Confederacy collapsed in April 1865, that plan gave way to something far more drastic.

The official account holds that Booth entered Lincoln’s presidential box, fired a single-shot derringer into the back of Lincoln’s head, then leapt to the stage — breaking his leg on landing — and shouted “Sic semper tyrannis!” before escaping on horseback. He was reportedly cornered twelve days later at the Garrett farm in Virginia and shot dead.

Paul Mellen’s research does not dispute that Booth was present at Ford’s Theatre that night, or that he was the architect of the conspiracy. What Mellen challenges is the assumption that Booth fired the fatal shot. His evidence points to a second man in Lincoln’s box — John Surratt — as the actual gunman, while Booth served as the visible, theatrical face of the plot. The question Mellen asks is: why would a trained actor and meticulous planner leave the most critical act to himself, when a more skilled operative was already in position?

John Harrison Surratt Jr. was born in 1844 in Maryland, the son of Mary Surratt — who would later be hanged as a co-conspirator in Lincoln’s assassination. By his early twenties, John Surratt had become one of the most active Confederate couriers and spies operating in the mid-Atlantic states, running messages and intelligence between Richmond and Montreal. He was also, remarkably, working simultaneously as a Union informant — a double agent operating at the highest levels of the Civil War’s shadow war.

Surratt was deeply embedded in the Booth conspiracy from its earliest stages. He was present at multiple planning meetings, helped coordinate the network of safe houses and escape routes, and was known to be in Washington on the day of the assassination. The official account placed him elsewhere that night — a claim that Paul Mellen’s research directly contradicts using primary source documents from the National Archives and Canadian government records.

After the assassination, Surratt vanished with remarkable efficiency. He crossed into Canada within days, aided by a network of Confederate sympathizers and Catholic clergy. From Montreal he sailed to Liverpool, then traveled to Rome, where he enlisted in the Papal Zouaves — the Vatican’s military force — under the assumed name “Watson.” He was not identified until 1866, when a fellow soldier recognized him in Egypt. He was arrested, extradited, and tried in 1867 — but the jury deadlocked and he was never convicted.

John Surratt lived until 1916, dying at age 72 in Baltimore. He outlived the assassination by more than 50 years — and, according to Paul Mellen, carried the true secret of what happened at Ford’s Theatre to his grave.

Harold Holzer is one of the most respected Lincoln historians in America. His books — including Lincoln at Cooper Union, Lincoln and the Power of the Press, and his landmark biography Lincoln: How Abraham Lincoln Ended Slavery in America — have shaped how generations of readers understand the 16th president. Holzer’s work draws on vast archival research and has earned him the Lincoln Prize, the Gilder Lehrman Lincoln Prize, and a National Humanities Medal.

But even Holzer’s exhaustive scholarship accepts the foundational premise of the official account: that John Wilkes Booth fired the shot that killed Lincoln at Ford’s Theatre on April 14, 1865. Paul Mellen’s research challenges that premise directly — not with speculation, but with primary source documents drawn from the National Archives, Canadian government records, and British historical files that mainstream Lincoln historians have not fully examined.

Where Holzer illuminates Lincoln’s life, presidency, and political genius, Mellen investigates the final minutes of Lincoln’s life and the 160-year cover-up that followed. The two bodies of work are complementary: readers who have devoured Holzer’s Lincoln biography will find in Mellen’s book a shocking coda — a reexamination of the assassination itself that upends the story’s ending.
