Many of the various Confederate states early regiments were shipped to Virginia as soon as they were formed.
A Goggle search 3rd Arkansas Infantry will bring another wealth of information.
Here is a brief bit from their website:
Arguably the most celebrated regiment fielded by Arkansas during the Civil War, the Third Regiment, Arkansas Volunteers, served in Virginia from its inception to its surrender at Appomattox Court House. The Third Arkansas was one of a handful of Arkansas regiments that maintained their organizational integrity throughout the war, and generally enjoyed competent, stable leadership. For most of its service, it was an integral part of the famous Texas Brigade, “Lee’s Grenadier Guard,” of the Army of Northern Virginia.

These companies organized in May and June, 1861, and traveled to Lynchburg, Virginia, where they were mustered into Confederate service, “for three years or during the war,” on July 5. The Third Arkansas was the first Arkansas regiment to enlist for the duration, the First and Second Arkansas having initially enlisted for one year and later enlisting “for the war.” Albert Rust, a prominent south Arkansas politician, was appointed colonel of the regiment. Vannoy Hartrog Manning, a lawyer from Hamburg, Arkansas, and captain of Company K, was appointed major. The Confederate War Department had initial misgivings about these volunteers from “the backwoods of Arkansas,” and decided to assign “real soldiers” to certain key positions in the regiment. Seth Maxwell Barton, a West Point graduate and native Virginian, was assigned as lieutenant-colonel. Another Virginian, Thomas Middleton Semmes, a recent Virginia Military Institute graduate, was assigned as the regimental adjutant. The Third Arkansas was then sent to a camp of instruction, where VMI cadets drilled them daily.
The Third Arkansas was then ready for four long years of war, participating in six campaigns, nine battles, five major engagements, five sieges, and a long list of military operations and skirmishes.
