Union Brigadier General William Vandever pursued Brigadier General 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.
