Organ Cave played a significant role during the American Civil War, as the cave is an abundant source of saltpetre, one of the most important minerals sought after by armies on both sides of the conflict. Saltpetre (potassium nitrate after been processed) is the primary ingredient in black powder and in its raw form (calcium nitrate) can be seen glittering on the walls and the floor of the cave. This cave furnished the Confederate Army 75% to 90% of the saltpetre for their army.
Confederate soldiers working under the directions of General Robert E Lee found that Organ Cave was not only an excellent place to extract this valuable mineral, but realized that the cave was a suitable facility to which further refine the saltpetre into a form suitable for the powder mills of Augusta, Georgia.
Visitors today can learn first hand how the soldiers processed, by hand, this nitre while walking the trails used by the soldiers and observing the large collection of equipment left behind by the Confederates. Along with the mining, the Confederates used the cave as a gigantic church: visitors appreciate the natural acoustics inside the appropriately named, "Chapel Room" that easily housed 1100 Confederates. This room is 365 feet long and 96 feet wide. Organ Cave is a living museum of America's heritage. Vistors only need to witness the massive underground chapel used by the Confederate soldiers, observe the markings and writings left by these men and even smell plus see the smoke left behind on the ceilings and walls over 150 years ago to understand that Organ Cave is much more than a textbook cave, it is history alive and vibrant.
