The Confederate government now faced the task of participating in the war while still defending the Texas frontier from the Comanches and their allies. The First Regiment, Texas Mounted Riflemen, was organized in the spring of 1861 and became the first regiment in Texas in Confederate service. The ten companies of the regiment occupied the old Army forts and made expeditions into Indian areas in northwest Texas as a show of strength. By the spring of the following year, the regiment was disbanded, with most of its members eventually becoming part of the Eighth Texas Cavalry, known as Terry's Texas Rangers. They saw action in many of the major battles of the Civil War.
They were replaced by the Frontier Regiment, made up of nine companies of volunteers. The regiment established patrols from sixteen forts from the Red River to the Rio Grande. By this time, the Indians realized how lightly guarded the frontier was and increased the boldness and frequency of their raids. Eventually, the Frontier Regiment was transferred to Confederate rather than state control and was used less often to fight Indians than to enforce the draft, track down deserters, and combat renegades and outlaws.
The third organization to deal with the Indian menace during the Civil War was the Frontier Organization, established in 1864. The Frontier Organization was a militia of able-bodied male citizens who lived in frontier counties and were not otherwise serving in the Confederacy. The militia was purely defensive and had neither the manpower nor the leadership to mount offensives against the Indians. By 1864, the Indians were conducting large raids against forts and settlements all along the frontier.

p.s. How many of the state troop "shirkers" were old men, discharged wounded soldiers and boys? I believe that if I was the parent of a 16 year old son in 1864, I just might have pulled some strings to keep him off the front lines.
