Byrne went on to serve with distinction under Morgan and commanded the artillery on several of his raids until he was court-martialed for his involvement in a bank robbery on one of those raids. The men not transferred back to his new unit continued to serve in various units, especially Cobb's Battery of the Orphan Brigade, until they were surrendered by Joseph E. Johnston on April 26, 1865, at Bennett Place. The remnants of Byrne's Battery were paroled on May 10.
