||As Maj. Gen. Nathaniel P. Banks’s Red River Expeditionary Force retreated down Red River,
Confederate forces under Maj. Gen. Richard Taylor attempted to slow the Union troops’ movements and, if
possible, deplete their numbers or, better yet, destroy them. The Union forces passed Fort DeRussy, reached
Marksville, and then continued east. At Mansura, Taylor massed his forces in an open prairie that controlled access
to the three roads traversing the area, where he hoped his artillery could cause many casualties. Early on the morning
of May 16, the Union forces approached, and skirmishing quickly ensued. After a four-hour fight (principally an
artillery duel), a large Union force massed for a flank attack, inducing the Rebels to fall back. The Union troops
marched to Simmsport. Taylor’s force could harass the enemy's retrograde but was unable to halt it.
