After waiting for the arrival of reinforcements, Maj. Gen. Steele advanced on April 9, but was stopped at Prairie D'Ane, a series of encounters that ended on April 12. Price's Confederates returned to Prairie D'Ane on April 13, falling upon Steele's rearguard under Thayer. After a four-hour battle, Price disengaged, and Steele's column continued to Camden. Steele made a feint toward Washington, but then withdrew to Camden, in order to resupply his army, which was then on half-rations. Price had stripped Camden of personnel in order to defend Washington, and the Union forces occupied the city on April 15 against no significant opposition, but found no supplies awaiting him.
