I did find William P on the LR ledger. He was Captured March 19, 1864 in Independence Co (Batesville area) Ark. He is listed under citizens arrested so he may have tried to deny CS service to get released. Normally Gen Steele did release most private citizens however if they determined a military man, he was sent on to a military POW camp. William was forwarded to Alton, I'll POW camp,where he probably remained the duration. Has to be him...gave his home as Texas Co, Missouri, same as is on his enlistment papers
