Other than the 1st, 4th, and 5th Regiments of Texas Infantry, the only Texas unit known to have served in Virginia was Captain W.H. Duke's battery of artillery. This company was originally mustered as of the 1st Texas Infantry but does not appear to have served in that unit very long. It subsequently became Company A, Southern Battalion. It was also an independent company in the Artillery Corps commanded by Major J. Thomas Goode. Duke's battery disbanded in June 1862 and some of the men are found to have served in Captain Whittington's Company C of the 19th Virginia Heavy Artillery. The other men joined various Texas organizations.

There is vague evidence that a company of Texas Rangers served in Virginia. The company used a black flag with a skull and cross bones emblem.

A company of Texas Rangers was supposed to have served in Wise's Legion.

Company K, 10th Virginia Cavalry was supposed to be known as the "Texas Rangers". Company C, 44th Virginia Infantry was known as the "Travis Rifles" but no definite connection to Texas has been made. The "Galveston Tigers" was Company D, 57th Virginia Infantry but no verification has been made of the company being raised in Texas. In the 59th Virginia Infantry, Company F is supposed to be designated as the "Texas Rangers". Also, Company I, 59th Rangers (Virginia?) was known as the "Texas Rangers" and served in West Virginia. At least one soldier in this unit was from Texas.
