The siege of Port Hudson was the final engagement in the Union campaign to recapture the Mississippi River in the American Civil War. While Union General Ulysses Grant was besieging Vicksburg upriver, General Nathaniel Banks was ordered to capture the lower Mississippi Confederate stronghold of Port Hudson, Louisiana, to go to Grant's aid. When his assault failed, Banks settled into a 48-day siege, the longest in US military history up to that point. A second attack also failed, and it was only after the fall of Vicksburg that the Confederate commander, General Franklin Gardner, surrendered the port. The Union gained control of the river and navigation from the Gulf of Mexico through the Deep South and to the river's upper reaches.
The Battle of Stones River, also known as the Second Battle of Murfreesboro, was fought from December 31, 1862, to January 2, 1863, in Middle Tennessee, as the culmination of the Stones River Campaign in the Western Theater of the American Civil War. Of the major battles of the war, Stones River had the highest percentage of casualties on both sides. The battle ended in Union victory after the Confederate army's withdrawal on January 3, largely due to a series of tactical miscalculations by Confederate Gen. Braxton Bragg, but the victory was costly for the Union army. Nevertheless, it was an important victory for the Union because it provided a much-needed boost in morale after the Union's recent defeat at Fredericksburg and also reinforced President Abraham Lincoln's foundation for issuing the Emancipation Proclamation, which ultimately discouraged European powers from intervening on the Confederacy's behalf.
The Vicksburg campaign was a series of maneuvers and battles in the Western Theater of the American Civil War directed against Vicksburg, Mississippi, a fortress city that dominated the last Confederate-controlled section of the Mississippi River.

Pemberton's forces stationed there.

While both of Walker's strikes were failures and the Confederates withdrew to Richmond, Union Major General Ulysses S. Grant still viewed the presence of Walker's men at Richmond to be a threat.
