After the Battle of Pleasant Hill, Maj. Gen. Nathaniel Banks‘ Army of the Gulf began their retreat back down the Red River to the Atchafalaya River. In the course of this retreat his forces fought several actions in attempts to fend off the advancing Confederates under Lt. Gen. Richard Taylor.
At Blair’s Landing in Red River Parish, Louisiana a mixed force of troops from Union Brig. Gen. Thomas Kilby Smith‘s Provisional Division, XVII Corps, and the Navy gunboats furnished protection for the army transports engaged Brig. Gen. Tom Green‘s Cavalry Division on April 12, 1864.
Green’s force charged the boats at the landing area. Hiding behind bales of cotton, sacks of oats, and other ersatz obstructions, the men on the vessels, along with the Navy gunboats, repelled the attack, killed Green, and savaged the Confederate ranks.
The Confederates withdrew and most of the Union transports continued downriver. On April 13, at Campti, other boats ran aground and came under enemy fire from Brig. Gen. St. John Richardson Liddell‘s Sub-District of North Louisiana troops throughout April 12–13. The convoy rendezvoused with Maj. Gen. Nathaniel Banks’s army at Grand Ecore, providing the army with badly needed supplies. The Confederates lost some 200 men while the Union force suffered only 7 casualties.
On April 23rd, the Union army’s advance party, commanded by Brig. Gen. William H. Emory, encountered Brig. Gen. Hamilton P. Bee‘s cavalry division near Monett’s Ferry, or Cane River Crossing in Natchitoches Parish, on the morning of April 23. Bee had been ordered to defend the area against a Union crossing and had dispersed his forces to take advantage of the area’s natural features.
Emory made a demonstration in front of the Confederate defenders in order to hold them in place. Meanwhile, he dispatched two of his brigades to search for other crossings. One brigade located a ford, crossed in force and attacked the Confederate’s flank. Bee was forced to order a retreat. The Union troops built a pontoon bridge and crossed the river, escaping a potential Confederate trap.
At Mansura on May 16th, General Taylor made an attempt to bring Banks to battle. He hoped to slow down the Union withdrawal and deplete their numbers or even destroy them. He massed his forces on an open prairie near the town and when the Union troops approached, opened fire with his artillery. After a four hour battle, the Union forces massed for an attack and the Confederates fell back. The Union forces continued on to Simmesport while the Confederates continued to harass them.
The final engagement of the campaign took place at Yellow Bayou on May 18th. The Union force had reached the Atchafalaya River the previous day but were force to wait while their engineers constructed a bridge across the river. Banks ordered Brig. Gen. Joseph A. Mower to defend their rear with his division while the construction took place.
General Mower order his troops to attack and they drove the Confederate line back. Taylor order a counterattack and forced the Union troops to give up ground. The Union troops eventually repulsed the Confederates. All the while, the bridge continued to be built. Eventually both sides withdrew and Banks’ Army was able to cross the river to safety.
The Red River Campaign was a Union fiasco, the outcome of which did not have a major impact on the war. It may have extended the length of the war by several months as it diverted Union efforts from the far more important objective of capturing Mobile, Alabama, an event that did not occur until 1865, and could probably have been accomplished by June 1864 if not for the Red River Campaign.
The failure of the campaign effectively ended the military career of Banks, and controversy surrounding his retreat, the presence of cotton speculators and the use of military boats to remove cotton dogged his early postbellum congressional campaigns. Admiral Porter realized a substantial sum of money during the campaign from the sale of cotton as prizes of war.
The Confederates lost two key commanders, Mouton and Green, and suffered casualties they could not afford. Perhaps more importantly, relations between the aggressive Taylor and cautious Kirby Smith were permanently damaged by their disagreement over Smith’s decision to remove half of Taylor’s troops following the battle of Pleasant Hill.
The lost opportunity to capture the entire Union fleet as it lay helpless above the falls at Alexandria haunted Taylor to his dying day, certain that Smith had robbed him a chance to cripple the Union forces. The arguments between the two generals resulted in Taylor’s transfer to command of the Department of East Louisiana, Mississippi, and Alabama soon after the campaign ended.
