James Murrell Shackelford (July 7, 1827 – September 7, 1907) was a lawyer, judge, and general in the Union Army during the American Civil War.

A few months later, on January 1, 1863, he was promoted to Brigadier General of Volunteers and assigned to command the 1st Brigade, 2nd Division, XXIII Corps.

[2] In July of that year, Shackelford took part in Edward Hobson's expedition in pursuit of the noted Confederate raider, John Hunt Morgan.

Shackelford's brigade finally cut off Morgan's remaining force at the Battle of Salineville in northeastern Ohio.

[4] Later that year, as Ambrose E. Burnside marched toward Knoxville, Tennessee, he bypassed the Cumberland Gap, leaving a single brigade posted there.

Burnside occupied Knoxville on September 1, 1863, and turned his attention back to the Cumberland Gap, dispatching Shackelford's brigade.

[3] Shackelford's cavalry helped to secure the vital cross roads at the Battle of Campbell's Station and participated in the Siege of Knoxville.

[1] In 1883, Congress realized that legal issues in Indian Territory had overwhelmed the resources of Judge Isaac C. Parker's court in Fort Smith, Arkansas.
