John Crawford Vaughn (February 24, 1824 – September 10, 1875) was a Confederate cavalry officer from East Tennessee.

[6] Even before Tennessee had seceded, in early 1861 Vaughn recruited two units from Monroe County to support the southern cause.

[8] Vaughn's troops moved back to East Tennessee in 1862 and fought against Union factions in Scott County.

Part of Longstreet's unsuccessful effort to take Knoxville in December, Vaughn was forced to retreat to upper East Tennessee.

[11] Following Jones' death at Piedmont, Vaughn led the remnants of the Confederate infantry across the Blue Ridge to Lynchburg, where it joined John C. Breckinridge's division arriving from Richmond following Lee's victory at the Battle of Cold Harbor, which in turn was shortly reinforced by Jubal Early's division.

After the Battle of Lynchburg, Breckinridge and Early pursued General David Hunter's retreating force to Salem, Virginia and then marched north, for the Shenandoah Valley.

In Early's invasion into Maryland that July, Vaughn's brigade was part of John Echols' division, of Breckinridge's corps, and was present for the Battle of Monocacy and Fort Stevens.

He was routed at the Battle of Morristown in October by General Alvan C. Gillem and was pushed back near Carter’s Station on the Watauga River.

[12] Two weeks later under the command of General John C. Breckinridge, Vaughn won a November skirmish against Gillem at the Battle of Bull's Gap and pushed him back to Strawberry Plains near Knoxville.

[13] In April 1865, Vaughn and his troops were near Christanburg, Virginia, moving towards North Carolina after news of Lee's surrender.

[14] Indicted for treason in Tennessee, in October, 1865, Vaughn moved his family to Thomas County, Georgia.
