Nitre and Mining Bureau

Last updated

The Confederate Nitre and Mining Bureau was a civilian government bureau to provide the Confederate States of America with needed materials such as copper, iron, lead, saltpeter, sulfur, zinc, and other metals. The Bureau oversaw civilian contracts and offered advice, instruction and guidance in the production of these materials. The Nitre [1] and Mining Bureau was also known as the "CSNMB", the "Bureau of Nitre" or the "Nitre Bureau". The Niter and Mining Corps was the military division of the Bureau. The Nitre and Mining Bureau was part of the Confederate Ordnance Department, under the supervision of General Josiah Gorgas. The Nitre and Mining Bureau was supervised by General Isaac M. St. John. The Central Ordinance Laboratory was headed by John Mallet.

Personnel

The Act establishing the Nitre and Mining Bureau by the Confederate Congress stated: "That said bureau shall consist of one lieutenant colonel as superintendent, three majors as assistant superintendents, six captains and ten lieutenants, in which shall be included the officers of the present nitre corps, who shall have the same pay and allowances prescribed for officers of cavalry of the same grades." [2] General Isaac M. St. John was subsequently made the superintendent of the bureau. Other individuals involved with or associated with the Nitre and Mining Bureau included: George Washington Helme, Joseph LeConte, Nathaniel Thomas Lupton, Richard Sears McCulloh and Thomas Edgeworth Courtenay.

Saltpeter

The Nitre and Mining Bureau is most known for their production of saltpeter (potassium nitrate) for the Confederacy. Because of the blockade of Southern ports, imported supplies of gunpowder and materials were kept away from the Confederacy, and had to be supplied within their own borders. Priority was given to the manufacture of gunpowder. The Secretary of War for the Confederate States said: "That Military commanders are directed and officers of the Niter Bureau are authorized to seize niter in the hands of private individuals who either decline to sell it or ask more than 50 cents per pound for it.... All quartermasters are directed to give precedence in transportation to niter over all other Government stores. Richmond, April 15, 1862." [3]

Civilian production of saltpeter was encouraged by small farm holders, tobacco and livestock owners, from cave dirt and other resources.

Barn dirt

Several pamphlets were printed by the Confederate Nitre and Mining Bureau to explain how loose dirt from ricks, smoke houses, barns and tobacco curing buildings could be treated to extract the nitrates. [4]

Cave dirt

Cave dirt was mined to produce calcium nitrate, which would be combined with potash to create potassium nitrate, a needed ingredient of gunpowder. Lookout Mountain Caverns, the Morrell Cave in Sullivan County, Tennessee, Nickajack Cave, Organ Cave and Selma, Alabama's limestone caves all supplied nitrates for the Nitre and Mining Bureau.

Nitre beds

Joseph LeConte, a professor of chemistry and geology at South Carolina University, wrote a pamphlet for the Nitre Bureau on the process for the manufacture of saltpeter in 1862. Nitre beds were constructed of a clay floor, well rammed, that was impervious to water, but with a drain to remove the fluids. Then black earth was added to a raised bed over this floor, made of dark manure. Twigs, leaves and other elements were added to create air passages and porosity through the dirt. A shed would be built around and over the heap to protect it from wind and rain. "The heap is watered every week with the richest kinds of liquid manure, such as urine, dung-water, water of privies, cess-pools, drains, &c." As the heap ripens, the saltpeter is brought to the surface. [5]

Night soil

Desperate for saltpeter necessary for the making of gunpowder, the Confederacy sent out agents around the South to collect deposits of "night soil", i.e. human excrement. John Haralson, an agent in Selma, Alabama of the Confederate Nitre and Mining Bureau, advertised the following in the local paper: "The ladies of Selma are respectfully requested to preserve the chamber lye [i.e. urine] collected about their premises for the purpose of making nitre. A barrel will be sent around daily to collect it."

Gunpowder works

The Confederate Powderworks in Augusta, Georgia, was used to manufacture gunpowder from the saltpeter, charcoal and sulfur produced by the Confederate Nitre and Mining Bureau.

Iron production

The Nitre and Mining Bureau was responsible for the mining, refining and production of iron. [6]

Because the production of iron was so important, the Bureau sent out information on the need to enforce the existing contracts with civilian companies and individuals. [7]

Lead, silver and zinc production

Lead and zinc were needed by the Confederate War Department for the manufacture of weapons and ammunition.

Some of the lead and zinc was mined in Arkansas and Missouri. "At the outbreak of the war, Confederate troops seized the rich Granby lead mines of southwest Missouri, then touted as able to provide all the lead needed for the Confederate cause. In 1861, 75,000 pounds of pig lead a month were being hauled overland to Van Buren (Crawford County), to be shipped to the Memphis, Tennessee, ordnance works. The loss of Missouri to the Union following the Battle of Pea Ridge in Arkansas effectively meant losing this important war materiel source. The Confederate Nitre and Mining Bureau mined lead and saltpeter (an ingredient in gunpowder) in Newton, Marion, Pulaski, and Sevier counties. However, these operations proved too close to enemy lines and were soon abandoned for more secure sources in Texas." [8]

Lead was also mined in North Carolina. The silver had to be separated from the lead ores, which was an expensive process. The Nitre and mining Bureau took over the Silver Hill, North Carolina mines production. "In the opening stages of the war, geologists and government agents underscored the value and scope of Silver Hill's lead deposits, initially renting Mines for six hundred dollars per month. Outside a well known mine in Wytheville, Silver Hill was the only other large-quantity mine in the southeast, and, with its machinery and facilities already in place, it made an important acquisition for the new government." [9]

Lead was also mined in Wytheville, Virginia, operated by the Union Lead Company. This lead mine supplied one fourth to one third of the lead used by the Confederate States, and was a principal target of the Wytheville Raid. [10]

The Nitre and Mining Bureau also looked for "lost silver mines" near Camden, Arkansas. These legends dated from the early years of the state, but the Confederacy was desperate enough to try to find these legendary mines. [11]

Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula KNO
3. It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre in the UK). It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or saltpetre in the UK).
