Taylor sent Brigadier General Henry E. McCulloch with a brigade of Texans to attack Milliken's Bend, which was held by a brigade of newly-recruited African American soldiers. McCulloch's attack struck early on the morning of June 7, and was initially successful in close-quarters fighting. Fire from the Union gunboat USS Choctaw halted the Confederate attack, and McCulloch later withdrew after the arrival of a second gunboat. The attempt to relieve Vicksburg was unsuccessful. One of the first actions in which African American soldiers fought, Milliken's Bend demonstrated the value of African American soldiers as part of the Union Army.
