75% of all regiments raise by Texas, Missouri and Arkansas prior to February 1862 were, by that one order, transferred out of the Trans Mississippi. That is why those Govenors threaten to seceed from the Confederacy and all future request for additional troops from the Trans Mississippi were stalled until they could no longer cross the Mississippi River.
By that example, all it would have taken is for Samuel Cooper to have requested from General Holmes that these men be detached to the Eastern theater in place of the regiments previously requested. A simple order from Holmes, who was a Richmond appointee anyway, on a piece of paper. Given that these men would never, and could never, return to the Trans Mississippi anyway, what difference would it have made? The Trans-Mississippi Department never regained the use of these men. As far as I can tell they didn't make, nor does anyone even mention that such a request was ever made.
True these men were later assigned to Bragg's Command under Arkansas and Texas commanders, I guess that this was as close to "getting back home" as these men could get, but there were good Arkansas and Texas commanders in Virginia also.
