Why is "Battle of Henderson's Hill" trending?

Wikipedia Overview

The Battle of Henderson's Hill, also known as the Bayou Rapides, saw a reinforced Union Army division led by Brigadier General Joseph A. Mower opposed by a regiment of Confederate Army cavalry and attached artillery under Colonel William G. Vincent. That evening, during a rainstorm, Mower sent one infantry brigade on a circuitous march to gain the rear of Vincent's command. The brigade's subsequent attack surprised and captured most of the Confederates. Mower could not exploit his minor victory because the arrival of additional Federal army and naval units was delayed. This clash occurred during the Red River campaign of the American Civil War which saw Major General Nathaniel P. Banks' Union army try to seize Shreveport, Louisiana, from its Confederate defenders led by Lieutenant General Richard Taylor.
