Unknown
Results:
Result(s): Confederate tactical victory (The results, however, forced Marmaduke to end his expedition, making this
a Union strategic victory.)
Description:
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.
