Armies rarely fight over seasoning, but by 1864, salt had become worth defending with your life.
Without refrigeration, salt was essential for preserving meat and food to feed armies and civilians alike, and Saltville's enormous saltworks made this small southwestern Virginia valley strategically important enough that Union forces attacked it twice. Combined with the nearby lead works at Wytheville and the regional railroad network, this became one of the Confederacy's most valuable industrial corridors, and the hills surrounding Saltville were transformed into a defensive landscape that's still remarkably visible in LiDAR.
The first major attempt to destroy the saltworks came on October 2, 1864, when Union Brig. Gen. Stephen G. Burbridge led troops into the valley, including the 5th U.S. Colored Cavalry, one of only a handful of Black cavalry regiments the Army organized. Confederate and local forces defended the approaches, and after heavy fighting, Burbridge was forced to withdraw.
Afterward, the Confederates strengthened the surrounding high ground, building additional earthwork forts southwest of town, including Fort Statham, Fort Breckinridge, and Fort Hattan, along with other works protecting the closer approaches. Rather than relying on one massive fortress, defenders used the steep ridges and hills themselves as part of the defensive system. LiDAR makes that strategy easy to understand, compact geometric earthworks suddenly appear on the hilltops where ordinary aerial photography shows little more than woods and pasture, their elevated positions offering commanding views across the valley approaches, with trenches still traceable across parts of the surrounding terrain.
The October battle also produced one of the darkest episodes tied to Saltville. After the Union withdrawal, wounded U.S. soldiers, particularly Black soldiers of the 5th U.S. Colored Cavalry, were murdered by Confederate troops, both on the battlefield and at hospitals where the wounded had been taken. Estimates of how many were killed vary among historians, though the National Park Service cites a general scholarly figure of roughly 45 to 50 African American soldiers.
Two months later, the Union came back. In December 1864, Maj. Gen. George Stoneman led another raid into southwestern Virginia, fighting Confederate forces around Marion before advancing on Saltville. By the night of December 20–21, only about 500 Confederate troops remained to defend the town, and Union forces overwhelmed the defenses and captured it. This time, they finished what the October expedition had failed to do, spending December 21 systematically destroying the saltworks, smashing kettles and machinery, and damaging buildings, pumps, wells, and stored supplies before withdrawing. The Confederates managed to repair some of the operation afterward, but it never fully recovered before the war ended a few months later.
More than 160 years later, much of that history has blended back into the Appalachian landscape. Ordinary satellite imagery shows the surrounding hills as mostly forest and pasture, but LiDAR tells a different story, stripping away the vegetation to reveal unmistakable artificial shapes on the hilltops, earthworks still standing above the same valley Union forces fought twice to take in 1864. What looks like a quiet mountain community today was once important enough that armies fought two separate battles over what lay beneath it.
