General Dockery's forces consisted of his own brigade and elements of Colonel Crawford's Arkansas Cavalry Brigade, including Poe's and McMurtrey's Cavalry Battalions. "Unfortunately," Price reported, "before Brigadier-General Dockery could execute this order he was on March 29 attacked at Mount Elba by a party of the enemy from Pine Bluff and completely routed.
