Granted, but Bragg was no longer in field command. Unless he had been sent to Richmond, Forrest could not have served under Bragg.
In his new position Bragg's counsel became War Department directives. Confederate commands were reorganized and new forces assembled from rear-area troops. When spring campaigns began in 1864, the number of Confederate troops available for field service were at their highest levels ever. Work of the Conscript Bureau and new policies/procedures/military laws put in place early that year paid valuable dividends.
