The Battle of Riggins Hill (September 7, 1862) was a minor engagement in western Tennessee during the American Civil War. A Confederate raiding force under Colonel Thomas Woodward captured Clarksville, Tennessee, threatening Union shipping on the Cumberland River. Several Union regiments led by Colonel William Warren Lowe advanced from nearby Fort Donelson and drove off the Confederates after a struggle lasting less than an hour. The action occurred during the Confederate Heartland Offensive but only affected the local area.
