Confederate forces of Brigadier-General James Chalmers advanced from Oxford, Mississippi to attack the Federal garrison at Collierville. The Confederate force struck a Federal cavalry camp on the north side of the town, routing the 7th Illinois Cavalry into the river bottoms and capturing 150 prisoners and 5 stands of colors, and 48 wagons of supplies. Fearing Union reinforcements from Germantown, Chalmers withdrew without taking the fort.
