In cooperation with Major General Ulysses S. Grant's offensive against Vicksburg, Union Major General 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.
At the battle of Port Hudson, Louisiana, May 27, 1863, the African American soldiers bravely advanced over open ground in the face of deadly artillery fire. Although the attack failed, the black solders proved their capability to withstand the heat of battle.
