Pulaski in Giles County, Tennessee — The American South (East South Central)
Fort Lilly
Guarding Vital Roads and Railways
From the summit of the prominent high ground ahead of you, White and Black Union soldiers peered over the ramparts of Fort Lilly, keeping an eye on traffic clattering along the "macadamized," or paved, Columbia Turnpike, which followed the current US 31, and puffing locomotives chugging along the National & Decatur Railroad. Fort Lilly was a cigar-shaped Union redoubt that conformed to the natural topography of what was nicknamed "Fort Hill," it served as the anchor for defenses protecting the busy transportation hub of Pulaski. U.S. Army units such as the 9th Indiana Cavalry and the 110th and 111th U.S. Colored Troops served here.
The USCT soldiers who served in Fort Lilly were primarily recruited from Black men who had been enslaved here in Giles County and Limestone County, Ala. They defended and repaired the critical railways and roadway infrastructure that kept supplies flowing to Union armies. These locally recruited soldiers served alongside USCT units from across Tennessee and other White U.S. Army units.
