Gov Clark of TX probably had ties with him:

"When Governor Houston refused to take the oath of allegiance to the Confederacy in the spring of 1861, the Secession Convention declared the office of governor vacant and elevated Clark to the position. As governor, he moved quickly to address problems brought about by secession. Regiments commanded by John S. (Rip) Ford and Henry E. McCulloch were mustered to protect the frontier, ad valorem and poll taxes were raised in an effort to stabilize the state's finances, and the state was divided into military districts for recruiting and organizing the troops required by the Confederate government. After the firing upon Fort Sumter and the outbreak of war, Clark worked closely with Confederate authorities to help obtain supplies for the army. The archaic state militia system was reorganized, and a system of training camps was built. Clark proceeded cautiously and within his constitutional powers. Even so, he exercised more authority and power than any previous Texas chief executive in recruiting, enrolling, and training troops, in purchasing weapons and supplies, and in communication with Confederate officials and governors of Mexican states"
So, learning more about Corwin could shed some light on what Young was referring to, possibly his appointment, or PROmotion?
I'll keep reading!
