Location: Clay County
Campaign: Marmadukes Second Expedition into Missouri (1863)
Date(s): May 1-2, 1863
Principal Commanders: Brig. Gen. William Vandever [US]; Brig. Gen. John S. Marmaduke [CS]
Forces Engaged: 2nd Division, Army of the Frontier and force under command of Brig. Gen. John McNeil [US]; Marmadukes Cavalry Division [CS]
Estimated Casualties: Unknown
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 Marmadukes raiders crossed the St. Francis River, they suffered heavy casualties and therefore ended the expedition.
Result(s): Confederate tactical victory (The results, however, forced Marmaduke to end his expedition, making this a Union strategic victory.)
