The Meridian Invincibles were established on May 1, 1861, under the command of W.F. Crumpton and William Spinks. On May 21, the Governor ordered the unit, which consisted of sixty-three members, to proceed to Corinth and go into camp under the command of Major General Charles Clark. The Invincibles eventually became Company H of the 14th Mississippi Infantry and would later see action at the Battle of Fort Donelson. They, along with 7000 confederate soldiers, would become prisoners of war.
