Richmond, Louisiana was an important part of the Confederate supply line for Vicksburg, Mississippi. After Union troops won battles at Milliken’s Bend and Young’s Point they were able to move against Richmond. Union Major General William Tecumseh Sherman ordered Brigadier General Joseph Mower’s brigade from the trenches around Vicksburg, and told him to coordinate an attack against Confederate forces in Richmond with Union Marine Brigadier General Alfred W Ellet.
The Union troops advanced on Richmond on June 15th 1863 with Ellet’s men in the lead. Confederate Major General John G Walker’s scouts learned of Ellet’s men movements. Walker had line of skirmishers made up of the 18th Texas Infantry; they stopped the initial Union forward movement. The Confederate held their line until Mower came up with his infantry, formed in line of battle and opened with their artillery. The battle continued until Mower’s men made it through a bayou and got on Walker’s flank.
Walker had gotten his supply wagons to safety, and finding himself outnumbered, he withdrew his men. As they pulled out of the area, the Confederate destroyed the bridges. The Union win at Richmond on June 15th 1863 took away another supply route from the garrison at Vicksburg.
