Historian Anthony Cohen recently retraced Sherman's March on foot and bike.

Among the soldiers on Sherman’s March to the Sea 150 years ago were former slaves.

One of them, according to documents from the time, was named Patrick Sneed. He’d escaped from slavery in Savannah, fled north, and joined the Union Army.

Last month, Anthony Cohen - a descendant from Sneed’s family - retraced that march on foot and bicycle. He’s also working on a film about the experience.

Cohen is president of the Menare Foundation in Germantown, Maryland. The nonprofit group works to preserve the history of the Underground Railroad.

He first stumbled on Sneed’s name while reading through some legal papers filed by his great, great grandfather. GPB's Sarah McCammon profiles the trek.
