The Battle of Vicksburg was a decisive Union victory during the American Civil War that divided the Confederacy and cemented the reputation of Union General Ulysses S. Grant. Union forces waged a campaign to take the Confederate stronghold of Vicksburg, Mississippi, which lay halfway between Memphis to the north and New Orleans to the south. The 47-day Siege of Vicksburg eventually gave control of the Mississippi River—a critical supply line—to the Union, and was part of the Union’s successful Anaconda Plan to cut off all trade to the Confederacy.
Battle of Vicksburg Begins
As the Civil War began, the South controlled the Mississippi River—a critical transportation corridor and supply line—from Cairo, Illinois, all the way down to the Gulf of Mexico. Vicksburg, given its strategic location on the east bank of the Mississippi River, was “the nailhead that holds the South’s two halves together,” according to Confederate President Jefferson Davis.
The Vicksburg campaign was one of the Union Army’s most successful endeavors in the Civil War—it was also one of the longest. Although the first attempt by General Ulysses S. Grant to take the city failed in the winter of 1862-63, he renewed his efforts in the spring.
Union Admiral David Porter had run his flotilla past the Vicksburg defenses in early May as Grant marched his army down the west bank of the river opposite Vicksburg, crossed over back into Mississippi and drove toward Jackson, the state capitol. After defeating a Confederate force near Jackson, Grant turned his troops back to Vicksburg.
On May 16, Grant defeated a force under General John C. Pemberton at Champion Hill, one of the Confederates’ last defenses outside of Vicksburg. Pemberton retreated back to Vicksburg, and Grant sealed off the city by the end of May. In three weeks time, Grant’s men had marched 180 miles, won five battles and captured some 6,000 prisoners.
Did you know? After the residents of Vicksburg dug more than 500 caves in the hills around the city and began living in them, Union soldiers started to refer to the town as a "Prairie Dog Village."
Siege of Vicksburg
Grant made some attacks after bottling Vicksburg but found the Confederates well entrenched. Starting on May 18, preparing for a long Siege of Vicksburg, Grant's army constructed 15 miles of trenches and enclosed Pemberton’s force of 29,000 men inside the perimeter. It was only a matter of time before Grant, with 70,000 troops, captured Vicksburg.
Confederate attempts to rescue Pemberton and his force failed from both the east and west, and conditions for both military personnel and civilians in Vicksburg deteriorated rapidly. Many residents—cut off from all supplies and rapidly running out of food—moved to tunnels dug from the hillsides to escape the constant bombardments.

After holding out for 47 days, Pemberton surrendered on July 4, 1863—Independence Day—and President Abraham Lincoln wrote that the Mississippi River “again goes unvexed to the sea.”
The Confederate defeat at Vicksburg, and a second Union victory downriver at Port Hudson, Louisiana, ensured that the Union would have complete control of the Mississippi River. Lincoln reportedly referred to the successful Vicksburg campaign as "the key to the war."
Today, the Battle of Vicksburg and the siege are commemorated at the . The town of Vicksburg—which had suffered miserably during the siege, with disease, starvation and death stalking soldier and civilian alike—would not celebrate the Fourth of July for 81 years.
