Union Brig. Gen. [[William Vandever]] pursued Brig. Gen. [[John S. Marmaduke]] to Chalk Bluff, where the Confederates hoped to cross the St. Francis River. To ford the river, Marmaduke established a rearguard that received heavy punishment on May 1-2. Although most of Marmaduke’s raiders crossed the St. Francis River, they suffered heavy casualties and therefore ended the expedition. <ref>[http://www.nps.gov/history/hps/abpp/battles/bystate.htm NPS.gov: NPS Battle Summaries]</ref>
