In Sept. 1864 he resigned his commission. There are a couple pages in his service record which are quite harsh. One states "He is useless as an officer".
His actual resignation signed by him states that he is "totally incompetent and inexperienced for my present position".
After his resignation he remained in the service as a 1st Sergeant. He was captured at Fort Blakely April 9 1865 and surrendered with Gen. Richard Taylor's Army in May 1865.
He had a few cousins who served with him in Company D; B.L Flowers & a few other Bush cousins. I've wondered if it wasn't a problem for him being an officer over kinfolk.
