The Battle of Milliken's Bend was fought on June 7, 1863, as part of the Vicksburg Campaign during the American Civil War. Major General Ulysses S. Grant of the Union Army had placed the strategic Mississippi River city of Vicksburg, Mississippi, under siege in mid-1863. Confederate leadership erroneously believed that Grant's supply line still ran through Milliken's Bend in Louisiana, and Major General Richard Taylor was tasked with disrupting it to aid the defense of Vicksburg. 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. Background In the spring of 1863, Major General Ulysses S. Grant of the Union Army began a campaign against the strategic Confederate-held city of Vicksburg, Mississippi. Grant's troops crossed the Mississippi River from the Louisiana side into Mississippi at a point south of Vicksburg in late April. By May 18, the Union army had fought its way to Vicksburg, surrounded it, and initiated the Siege of Vicksburg. During the campaign, Grant had kept a supply base at Milliken's Bend in Louisiana as part of his supply line. Soldiers had been housed at the site before being deployed in the campaign, and a number of hospitals had been established there. During the siege, however, Grant had a different supply line opened: the Union Navy took control of part of the Yazoo River in the Chickasaw Bayou vicinity and established a point from which supplies could be sent overland behind the Union lines. While a position at Milliken's Bend was still held, its importance was greatly reduced, since the Yazoo River position had become Grant's primary supply depot. Meanwhile, Confederate President Jefferson Davis was pressuring General E. K. Smith, commander of the Trans-Mississippi Department, to attempt to relieve Vicksburg's garrison. Smith was unaware that Grant had moved his supply line to the Yazoo River, and still believed that Milliken's Bend was a primary Union supply depot. Immediate
