Philip Henson was born December 28, 1827, in Blount Springs. By the time he died in 1911, he’d spied on the Confederacy for Ulysses S. Grant, survived Confederate captivity, and become the first Special Secret Service Agent of the United States.
His father worked as a Federal Indian Agent, and young Henson traveled with him through Kansas, Mississippi, Oklahoma, Tennessee, and Texas before his father’s death in 1839 left twelve-year-old Philip supporting his widowed mother and siblings - as a mail carrier, a herder, and an overseer. By the eve of the Civil War he was running a store in Corinth, Mississippi.
Former Texas governor Sam Houston recruited him as a Union spy, sending him to Illinois to meet Congressman Elihu Washburne and a then-obscure colonel named Ulysses S. Grant. What followed was a genuine double game: Henson scouted and spied for General Grenville Dodge, while also arranging to scout for the Confederates - a cover only, meant to build trust rather than actually betray Union secrets. It worked well enough that Confederate General Leonidas Polk told him which Fort Henry and Fort Donelson commanders were weakest, intelligence that fed directly into Grant’s early victories. During the Vicksburg campaign, Henson talked his way into General John C. Pemberton’s confidence and came away with the city’s defenses. Dodge called him his “most colorful spy”; Nathan Bedford Forrest, who eventually arrested him in 1864, called him the most dangerous spy operating inside the Confederacy.
Forrest’s men held him for somewhere between six and nine months (sources give slightly different figures) before he escaped back to Union lines. His own biography, published in his lifetime, doesn’t soften what that captivity involved: confinement in “sweat-boxes,” manacles forged to his ankles and wrists, chained to iron balls - injuries he reportedly still felt pain from decades later.
After the war, Grant asked him to investigate Lincoln’s assassination - an inquiry that stretched across Grant’s presidency and beyond, more than twenty years, ending unresolved when Grant died in 1885 without authorizing the findings’ release. Separately, upon Grant’s election, Henson became the United States’ first Special Secret Service Agent, serving in that role until Grant’s death. He was denied a government pension afterward and supported himself giving lectures on his espionage career, reportedly growing a beard more than six feet long as part of the show. He died in 1911 at his son’s home in Paris, Texas, and is buried beside his wife Celestine in Corinth, Mississippi - a long way, geographically, from the Blount Springs he started out in.
