Salt in the American Civil War
Salt played a role during the Civil War. Salt not only preserved food in the days before refrigeration, but was also vital in the curing of leather. Union general William Tecumseh Sherman once said that "salt is eminently contraband", as an army that has salt can adequately feed its men.
The most important saltworks for the Confederacy were at Saltville, Virginia. In late 1864, the Union army twice advanced to capture the saltworks, as it was the last prominent source of salt for the eastern Confederate states. The October 1864 Battle of Saltville I saw the Confederate able to repulse the charge, but the next December in the Battle of Saltville II Union forces under George Stoneman managed to destroy the vital saltworks. Two months later the salt works were back to work for the Confederacy, although the destroyed railroad system around the area hampered its distribution. 
In Georgia, the price of salt depended on one's family circumstances. Heads of families could purchase a half-bushel of salt for $2.50. If a widow had a son in the Confederate army, the price was only $1.00. But if the widow's husband served his nation, the price was free. Local court clerks sent the salt requests to the state government, which in turn allotted the salt to the counties as requested.
Florida's greatest contribution to the Confederate war effort was in producing salt. With a total investment of $10 million, Floridian salt plants worked 24 hours a day boiling salt from sea water, mostly in the area between Saint Andrews Bay and St. Marks, Florida. Occasionally, Union forces came ashore just to destroy the boilers. Confederate law made those involved in salt-making immune to being drafted, making it a popular profession in war-time Florida; the estimated total workers involved was 5,000.
One way Southern families acquired salt was to boil the dirt in areas where they had previously cured meats. They would dig it out, and strain it.
Avery Island, off the Louisiana coast, gave the Confederacy a huge supply of rock salt until the Union captured it. However, Confederates never realized that similar structures to the rock salt mine were all along the Louisiana and Texas coasts of the Gulf of Mexico, and therefore salt could have been more easily attained if they had but realized it.
