Harriet Tubman: The General Who Could Not Read
On the night of 2 June 1863, three Union steamboats moved up the Combahee River in South Carolina through water the Confederates had mined. The person who knew where the mines were, having gathered the intelligence herself, was a woman in her forties who had escaped slavery fourteen years earlier and could not read a map. By morning roughly 750 enslaved people had walked onto those boats. In 2021 the US Army formally recognised her as the first woman to plan and lead an American military raid.
Dorchester County
She was born Araminta Ross in March 1822 in Dorchester County, Maryland, to Rit, who was enslaved, and Benjamin Ross, who was free. Her enslaver, Edward Brodess, broke the family up and hired her out from the age of six to mind other people's children, collecting her wages himself. She was beaten severely and often.
At around thirteen she refused to help restrain a man who had fled, and an enslaver hurled a two-pound weight that struck her in the head and fractured her skull. The injury never healed properly. For the rest of her life she suffered dizziness, pain and sudden sleeping spells -- described variously as narcolepsy or hypersomnia -- accompanied by intense visions. She understood these as messages from God, and they became the organising fact of her interior life. Historians now treat the disability not as a footnote but as central to both her identity and her work.
Guided by Stars
She married John Tubman, a free man, in 1844 and took his surname. In 1849, learning that her enslaver's debts would probably mean her sale, she ran. Her brothers set out with her and turned back; she went on alone to Philadelphia, navigating by the stars.
In Philadelphia she met the abolitionist William Still, and between roughly 1850 and 1860 she began going back. The exact tally is contested -- accounts range from about thirteen missions to nineteen journeys, eleven of them running all the way to Canada -- but the figure that historians agree on is that she personally brought out around seventy people, including her own parents, while giving instructions to another fifty or sixty who escaped on their own. That correction matters, because nineteenth-century admirers inflated the numbers into the hundreds and the inflation has proved hard to kill. Her own claim was narrower and more impressive: "I never ran my train off the track and I never lost a passenger."
Black Americans called her Moses.
General Tubman
In the late 1850s she met John Brown, who was impressed enough to call her General Tubman. She supplied him with geographical expertise and recruited formerly enslaved men for the 1859 raid on Harpers Ferry, though illness kept her from taking part in the attack itself.
When the Civil War came she enlisted with the Union Army in 1861 as a nurse. By 1863 she had been made a scout and was organising a network of spies drawn from local enslaved communities -- people who knew where troops were, where supplies moved, and where the river had been mined. That network produced the Combahee River Raid, which freed some 750 people and burned a string of plantations. It was a rare instance in that war of an operation designed and led by a Black woman, and the Army took 158 years to say so officially.
Auburn
After the war she settled in Auburn, New York. She married Nelson Davis, a Union soldier, in 1869; he died in 1888. She fought a long and largely unsuccessful battle for a federal pension commensurate with her service. She founded the Home for the Aged, which took in elderly African Americans including those with paralysis, epilepsy and blindness, and she raised money for it through the AME Zion Church. She worked for women's suffrage alongside Lucretia Mott, Susan B. Anthony and Elizabeth Cady Stanton. She died of pneumonia on 10 March 1913, in the home she had built, at about ninety-one.
Why Harriet Is Called a Genius
The faculty in question is operational, and it is documented rather than mythologised. Tubman ran what amounted to a covert extraction network for a decade without losing a single person, against an adversary with legal authority, financial motive and organised slave-catching patrols. Doing that requires holding an enormous amount of information in memory: the marshland terrain of Dorchester County in detail, seasonal water levels, patrol habits, safe houses, which free Black sailors could carry a message north. She could not read or write, so all of it lived in her head. She used natural remedies, timed departures to Saturday nights when notices could not be printed until Monday, and built her intelligence networks from people the Confederacy did not think of as people. The National Women's History Museum emphasises exactly these things -- terrain mastery, network-building, strategic planning of military operations -- and John Brown's "General Tubman" is contemporaries' testimony rather than posthumous inflation.
The honest counter-case begins with the word itself. This is practical intelligence, not intellectual achievement in the conventional sense: she left no writings, developed no doctrine, and her strategic insight cannot be separated from courage and physical endurance in the way a scholar's can. Nothing in the sources shows historians formally calling her a genius. And the popular record has been persistently overstated -- the hundreds she supposedly rescued, the exact mission counts -- so that the real, verifiable achievement gets buried under embellishment it never needed.
What survives scrutiny is a spatial and organisational mind of rare quality, operating under lethal pressure, with a brain injury that produced blackouts. Call it tactical genius and the label holds.
Legacy
The pension she was denied in life has been replaced by honours she cannot collect. In 2024 the US Mint issued a commemorative coin, and Maryland posthumously commissioned her a brigadier general in its Army National Guard. She remains the most recognisable figure of the Underground Railroad, which is slightly unfair to her: the decade of covert rescues was the first half of a career whose second half was military.
