The Battle of Morristown took place during the American Civil War in present-day Hamblen County, Tennessee on October 28, 1864. Union forces under General Alvan C. Gillem attacked Confederate forces under General John C. Vaughn who were defending Morristown, Tennessee. Vaughn's Confederates were routed and Gillem's forces pursued them into nearby Russellville, Tennessee.

Alvan Cullem Gillem was a general in the Union Army during the American Civil War. Although Southern-born, he remained loyal to the Federal government and fought in several battles in the Western Theater before commanding occupation troops in Mississippi and Arkansas during Reconstruction. He later played a prominent role in the Modoc War in 1873.
