After waiting for the arrival of reinforcements, General Steele advanced on April 9, but was stopped in the Battle of Prairie D'Ane, a series of encounters that ended on April 12. Steele 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 facing no significant opposition. Operations to resupply the Union army at Camden were frustrated by the Battle of Poison Spring (April 18) and the Battle of Marks' Mills (April 25). The latter battle was particularly devastating, as the Confederates captured most of the supply column, numbering some 1,400 troops and more than 200 supply wagons. Steele abandoned Camden and retreated toward Little Rock. The pursuing Confederate forces caught up with him at Jenkins' Ferry, where they fought a largely indecisive but bloody battle on April 30.
