The Spy Who Led an Army

Hey Coastal,

You know the Harriet Tubman story. The Underground Railroad, the thirteen trips back into slave territory, the danger, the nerve.

This isn't that story.

This is what happened after. When the Union Army brought her to a small occupied town on the South Carolina coast and, without quite meaning to, handed her the tools to plan and lead an armed raid deep into Confederate territory. No woman in American history had ever done that before. She was paid about $200 for it. It took the country until 2024 to finish settling the debt.

In May 1862, Harriet Tubman arrived in Beaufort, South Carolina, a small Union-held town sitting deep inside enemy territory. She'd already spent a decade as one of the most effective conductors of the Underground Railroad, personally leading roughly seventy enslaved people to freedom across about thirteen trips back into Maryland. That's the well-documented figure, not the inflated one you sometimes hear. It's still an extraordinary number for one person operating alone, under constant threat of capture.

But Beaufort wasn't the Underground Railroad. It was something new.

The Union Army put her to work as a nurse, a cook, a laundress. Ordinary support roles, the kind of work available to a Black woman attached to an occupying army. It should have stayed that way.

It didn't.

Tubman started building something. She recruited eight or nine local scouts, spies, and river pilots, formerly enslaved people who knew the Lowcountry's rivers, marshes, and rice plantations better than any Union officer ever could. She trained them. She led them personally into enemy territory, gathering intelligence behind Confederate lines.

The Combahee River, winding through some of the wealthiest rice plantation country in the Confederacy, was seeded with torpedoes, underwater mines meant to keep Union gunboats out. Tubman's network mapped them. Precisely enough that when the moment came, Union boats could sail straight through water that should have destroyed them.

That moment came on the night of June 1, 1863.

Three armed Union vessels left Beaufort carrying roughly 300 Black soldiers of the Second South Carolina Volunteers, under Colonel James Montgomery, along with a company of the Third Rhode Island Heavy Artillery. Tubman went with them. One ship ran aground almost immediately and had to turn back. The other two pressed on into the dark.

Around three in the morning, they reached the mouth of the Combahee. A small Confederate guard fled at first contact, running to raise the alarm, but by then it was already too late to stop what was coming. Union forces moved up the river through the morning, burning plantation buildings and destroying Confederate supply lines as they went.

Then the boats sounded their steam whistles.

That was the signal. Enslaved people who'd been hiding along the riverbank, warned in advance by Tubman's network, ran for the boats. Sources disagree on the exact number, some say more than 700, others cite figures approaching 800, but by any account, it was one of the largest single acts of emancipation in American history, all in the span of a few hours. Roughly 100 of the men freed that day enlisted directly in the Second South Carolina Volunteers before the sun was fully up.

Harriet Tubman had just planned and led the only United States military operation ever commanded by a woman.

She kept serving. Nurse, cook, scout, for more than three years total. When it was finally over, the Army paid her roughly $200 for the entire span of her service.

She used what little she had to build a laundry facility, teaching freedwomen skills they could use to support themselves. Then she spent the better part of the next four decades fighting Congress for a pension that actually recognized what she'd done.

In 1898 and 1899, she petitioned again. Secretary of State William Seward personally testified on her behalf, writing that he had known her "long as a noble high spirit, as true as seldom dwells in the human form." It should have been enough. Congress increased her pension, but on paper, as the widow of a U.S. Colored Troops veteran, her husband, Nelson Davis, not as recognition of her own military service. The country had a woman who planned and led a Civil War raid sitting right in front of it, and it still couldn't bring itself to call her what she was.

Harriet Tubman died in 1913. She never received full military recognition in her lifetime.

In November 2024, in a Veterans Day ceremony, she was posthumously named a General in the Maryland National Guard.

It's not nothing that this happened. It's also worth sitting with how long it took. A woman who ran spy networks behind enemy lines, who mapped minefields by hand, who led armed men into Confederate territory in the dark, waited more than a century for the title to catch up to the work.

That's not a tidy ending. We're not going to pretend it is. But it's an honest one, and honestly, it's the part of her story most people never get told.

Tubman wasn't the only person from this stretch of coast who did something the country almost couldn't process at the time.

Robert Smalls was born enslaved in Beaufort in 1839. In May 1862, the same year Tubman arrived in that same town, Smalls was working as a crewman aboard a Confederate transport ship called the Planter. Late one night, with the ship's white officers ashore, Smalls and a small crew of enslaved men took control of it, picked up their own families waiting at a nearby wharf, and sailed the Planter straight past Confederate checkpoints and out to the Union blockade, flying a white bedsheet as a flag of surrender.

He'd just delivered a Confederate warship to the Union Navy, with his own hands, in the dark, at enormous personal risk.

Smalls went on to serve in the Union Navy, then spent nine years in the U.S. Congress, representing the very district he'd once been enslaved in. He's buried at Tabernacle Baptist Church in Beaufort, the same church that unveiled a monument to Harriet Tubman in 2024.

Two people, one small occupied town, the same year, both doing something almost nobody thought was possible. That's not a coincidence. That's what happens when a place becomes a crack in the wall.

Beaufort isn't just where this story happened. It's still there. The visitor center, the church, the actual river crossing, all of it standing, all of it visitable.

This week's blog is a walking and driving guide to the real places tied to Tubman's raid, including a bridge that now carries her name across the very river she guided Union gunboats up in 1863.

She built a spy network by hand, mapped a minefield by memory, and led an army through it in the dark. She was paid $200 and made to wait 111 years for the title she'd already earned in 1863.

We tell you the parts of history that are hard to sit with, not just the parts that feel good. This is one of them. It's also one of the best stories we've ever gotten to tell you.

Until Next Tide,
