Nathaniel P. Banks’s army moved against the Confederate stronghold at Port Hudson on the Mississippi River. On
May 27, after their frontal assaults were repulsed, the Federals settled into a siege which lasted for 48 days. Banks
renewed his assaults on June 14 but the defenders successfully repelled them. On July 9, 1863, after hearing of the
fall of Vicksburg, the Confederate garrison of Port Hudson surrendered, opening the Mississippi River to Union
navigation from its source to New Orleans.
