The Army of 10,000 was a hastily-assembled volunteer unit of Mississippi troops in the American Civil War sent to support Confederate forces in Kentucky during the winter of 1861-1862.

Volunteers enlisted in the Army for a 60-day term of service, and after performing garrison duty in Kentucky, they were sent home in February 1862 and disbanded.

[1] In response to a call for support from Confederate General Albert Sidney Johnston, Mississippi Governor John J. Pettus asked for 10,000 volunteers to enlist in the Army on September 28, 1861.

Volunteers began assemble at Corinth and Grenada for 60 days military service, with the men supplying all of their own weapons and equipment.

Alcorn was dismissive of the effectiveness of his troops, calling them "inexperienced shot-gun militia",[4] and indeed, most of the men were armed with shotguns they had brought from home rather than military-standard weapons.
