Editing Montgomery County, Tennessee (section)

==History==
The county was named for [[John Montgomery (pioneer)|John Montgomery]], a soldier in the [[American Revolutionary War]] and an early settler who founded the city of Clarksville. It was authorized on April 9, 1796, when the western portion of Tennessee County, which since 1790 had been part of the [[Territory South of the River Ohio]], became part of the new state of Tennessee. (In 1790, North Carolina had ceded its western lands to the Federal government to create what was also known as the Southwest Territory.) The eastern portion of old Tennessee County was, at the same time Montgomery County was formed, combined with land taken from [[Sumner County, Tennessee|Sumner County]] to form [[Robertson County, Tennessee]]. Later acts of the [[Tennessee General Assembly]] had further reduced Montgomery County by 1871 to its current size and boundaries.<ref name=bluebook/>

Montgomery County was the site of several early [[potassium nitrate|saltpeter]] mines. Saltpeter is the main ingredient of gunpowder and was obtained by leaching the earth from local caves. Bellamy Cave near Stringtown still contains the remains of two dozen saltpeter leaching vats. It appears to have been a large operation. Cooper Creek Cave shows evidence of extensive mining and contains the remains of "many saltpeter hoppers." Both were probably mined during the [[War of 1812]]. Dunbar Cave is reported to have been mined for saltpeter during the [[Mexican–American War|Mexican War]] of 1848, but commercial development has destroyed any evidence of this. Little mining is likely to have happened here during the [[American Civil War|Civil War]], since the [[Union Army]] captured and occupied this part of Tennessee in early 1862.<ref>Matthews, Larry E.
