Battle of Mansfield

April 8, 1864

The Battle of Mansfield was the deciding engagement of the Red River Campaign, and it was the last major victory by a Confederate army during the American Civil War.

By the spring of 1864, Confederate Louisiana had shriveled to the northwestern area of the state. The capital had moved to Opelousas in 1862 and then to Shreveport in the spring of 1863. At the urging of Union Army Chief-of-Staff Henry Halleck, President Abraham Lincoln approved an offensive against the remaining Confederate forces in Louisiana in the spring of 1864. Named the Red River Campaign, Halleck's plan consisted of a three-pronged assault.

  1. Major General Nathaniel P. Banks would march twenty thousand troops from the area around New Orleans across southern Louisiana and occupy Alexandria, Louisiana near the center of the state, before moving on to Shreveport.
  2. Rear Admiral David Dixon Porter would ascend the Red River and join Banks at Alexandria with over thirty warships and an accompanying supply fleet. A land force of ten thousand soldiers, commanded by Brigadier-General Andrew Jackson Smith and detached from William T. Sherman's Army of the Tennessee, would protect Dixon's flotilla.
  3. After Banks and Porter joined forces and continued upriver toward Shreveport, Major General Frederick Steele would lead another ten thousand Union soldiers out of Little Rock, Arkansas and approach Shreveport from the north or east.

The campaign began on March 12, as Porter's fleet entered the mouth of the Red River from the Mississippi River. Events went well for the Federals initially. On March 14, Smith's soldiers overran Fort DeRussy and captured a Rebel garrison of approximately three hundred men. On the next day, Porter and Smith moved upriver and occupied Alexandria unopposed. Banks was behind schedule, and the forward elements of his army did not reach Alexandria until March 23. Banks himself did not arrive until the next day. At last united, the combined Federal forces moved upriver to Grand Ecore.

On April 6, Banks chose to leave the Red River and the protection of Porter's fleet to travel up an inland road toward Shreveport. By the time that his whole force was in motion, the column of cavalry, artillery, infantry, and supplies stretched over twenty miles along the narrow road. Making matters worse, Banks had positioned his supply train between his vanguard cavalry unit and their infantry support. As the cavalry, led by Brigadier-General Albert L. Lee, approached Sabine Cross-Roads on April 8, they encountered up to fourteen thousand Rebels, commanded by Major General Richard Taylor. Lee ordered his horsemen to dismount and requested reinforcements from Banks. Throughout the morning, Lee probed the Confederate lines, while Taylor hoped for a Union assault. When the Federals did not attack, Taylor's men advanced in the late afternoon.

The assault began on the Confederate left and did not go well initially. Led by Brigadier-General Alfred Mouton, the Rebels were halted almost immediately by blistering rifle and artillery fire. A second charge produced the same results and cost Mouton his life. On the right, events went much better for the Rebels. Two Texas cavalry units outflanked the Federals, forcing a retreat that quickly turned into a rout along the entire Union line. As reinforcements arrived from Banks's strung-out army, the Federals put up a second line, which the Confederates also flanked, prompting a second retreat. This time, the fleeing Yankees swarmed past their supply train on the narrow road abandoning 150 wagons and twenty artillery pieces. When the Rebel assault slowed due to fatigue and looting of the Union supply train, Banks was able to restore some semblance of order and established a third line. The Yankees withstood several more Confederate charges during the afternoon, before Taylor halted the action at nightfall to regroup.

The Battle of Mansfield was an astonishing Confederate victory. Throughout the engagement, Banks was never able to take advantage of his superior numbers because of poor troop deployment along the narrow road. Fewer than one-half of the soldiers at his disposal participated in the battle. The Rebels inflicted staggering losses on the Federals, including the loss of over two hundred supply wagons, twenty artillery pieces, and 2,200 human casualties, with approximately seven hundred men killed and wounded and 1,400 captured. The Confederates reported one thousand casualties. During the night, Banks ordered his army to fall back and to regroup at the town of Pleasant Hill. The Rebel victory marked the beginning of the Union retreat from the Red River Valley, and it was the last major triumph by a Confederate army during the Civil War.
