Union generals wanted a stronghold. They chose a high plateau hugged by the Kentucky River palisades to store millions of pounds of beef, thousands of mules, and stockpiles of gunpowder. But the site's true gravity shifted in 1864 when the Union opened enlistment to enslaved men. Thousands fled their masters. They risked everything, dodging slave catchers and rebel patrols, just to reach the camp gates. Once inside, these men put on blue wool uniforms, grabbed Springfield rifles, and formed eight regiments of United States Colored Troops. Over 10,000 Black soldiers enlisted there. It became the third-largest USCT recruiting center in the nation.

Escape wasn't just for the men, though. Their wives and children followed them, seeking safety under the Union flag. But the army didn't want them. In November 1864, officers forced over 400 refugees out of the camp into a freezing rainstorm. More than 100 died. This brutal expulsion sparked a massive public outcry in the North, forcing the government to build actual shelters for the families. Even better, the tragedy pushed Congress to pass a law in March 1865 that officially freed the wives and children of all Black Union soldiers. So, a place built for war actually became a crucial hub of freedom. A messy, painful step toward emancipation.
