Description: |
Early in the morning of May 21, 1863, Maj. Gen. Christopher C. Augur’s Union division advanced
from Baton Rouge toward the intersection of Plains Store and Bayou Sara roads on the way to secure a landing, on
the river, for Maj. Gen. Nathaniel Banks. Col. Benjamin H. Grierson’s cavalry, in the lead, encountered
Confederate forces under the command of Col. Frank P. Powers and skirmishing ensued. As the morning
progressed the Union infantry approached the crossroads and came under fire, bringing on a general engagement.
At noon, Col. W.R. Miles set out for Plains Store with Confederate reinforcements. By the time that Miles arrived in
the area late in the day, the fighting had ceased, the Rebel forces had retreated, and the Federals were preparing
camps for the night. Miles attacked the Union forces and, at first, drove them, but they regrouped and
counterattacked. Miles could not stand against the overwhelming Union force and retired into the Port Hudson
perimeter. The battle ended, and the last Confederate escape route from Port Hudson was closed. |
