Most of the people in west Texas were Unionist, as their ties were stronger with California and Colorado than with the slave plantations in east Texas.

Most of the people in west Texas were Unionist

Unless you are referring to the comanches, there were hardly any people even living in west Texas as of 1860 much less siding with the unionists. The unionist factions in Texas were almost all concentrated around a few small Germanic communities in the inner hill country. They were a tiny fraction of the state's population and an even tinier fraction of the unionist southerners who fought for the north during the war.
