Beauregard continued commanding the defenses of Petersburg in the early days of the siege, but with the loss of the Weldon Railroad in the Battle of Globe Tavern (August 18–21), he was criticized for not attacking more forcefully and he became dissatisfied with the command arrangements under Lee. He hoped for an independent command, but his desires were thwarted in two instances: Lee chose Lt. Gen. Jubal Early to lead an expedition north through the Shenandoah Valley and threaten Washington, and Davis chose Lt. Gen. John Bell Hood to replace the faltering Joseph E. Johnston in the Atlanta Campaign.
