The Siege of Vicksburg was a major military operation during the American Civil War. It lasted from May 18 to July 4, 1863. Vicksburg, Mississippi, was a vital Confederate stronghold located on the Mississippi River.

Capturing this city was a central goal of the Northern strategy known as the Anaconda Plan. By taking Vicksburg, the Union could control the Mississippi River. President Abraham Lincoln described the city as "the key to the war."

The campaign began with a series of strategic movements by Union Major General Ulysses S. Grant. Grant led the Army of the Tennessee across the Mississippi River at Bruinsburg. His troops moved northeast and won battles at Port Gibson and Raymond. They also captured Jackson, the state capital of Mississippi, on May 14, 1863. These victories forced the Confederate leader, Lieutenant General John C. Pemberton, to retreat. Pemberton moved his Army of Mississippi into the defensive lines surrounding Vicksburg.

The Confederate defenses were very strong due to the local terrain. Pemberton had only 18,000 troops to defend the city. Grant had over 35,000 soldiers, with many more arriving. Despite being outnumbered, the Confederates held high ground like hills and steep knobs. The defensive perimeter included various structures like gun pits, trenches, and redoubts.

Notable fortifications included Fort Hill, the Stockade Redan, and the Great Redoubt. These lines stretched for miles and made the city nearly impossible to enter by force.

Grant attempted to take the city through direct attacks before starting the siege. The first major assault occurred on May 19. Union troops from William T. Sherman's corps tried to reach the Stockade Redan. They had to cross a steep ravine and a deep ditch under heavy fire. The attack failed, resulting in 157 Union soldiers killed and 777 wounded.

The Confederates lost only eight men killed and 62 wounded during this fight.

A second, larger assault took place on May 22. Grant used 220 artillery pieces and naval gunfire from Rear Admiral David D. Porter's fleet to soften the defenses.

Union soldiers used ladders and planks to try and scale the walls. One group, called the "forlorn hope," led the way down Graveyard Road. Other units, like the 22nd Iowa Infantry, gained a small foothold at the Railroad Redoubt. However, the massive Union effort could not break through the Confederate lines.

After the failed assaults, Grant began formal siege operations on May 25. A siege is a military tactic where an army surrounds a city to cut off all supplies.

The Union forces held the perimeter for more than 40 days. Inside Vicksburg, the Confederate garrison faced extreme hardship. Their food and supplies were almost completely gone. On July 4, 1863, the Confederate forces finally surrendered.

The fall of Vicksburg had massive consequences for the war. It gave the Union total command of the Mississippi River. This victory, along with the fall of Port Hudson on July 9, split the Confederacy in two. It cut off the Trans-Mississippi Department, including Arkansas and Texas, from the rest of the Confederate states. Many historians consider the surrender at Vicksburg and the battle at Gettysburg as the turning points of the war. The loss significantly weakened the Confederacy's ability to continue its military efforts.
