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. The Union Army of the Tennessee under Major General Ulysses S. Grant gained control of the river by capturing this stronghold and defeating Lieutenant General John C. Pemberton's forces stationed there.

The Battle of Arkansas Post, also known as Battle of Fort Hindman, was fought from January 9 until 11, 1863, near the mouth of the Arkansas at Arkansas Post, as part of the Vicksburg Campaign of the American Civil War. Although a Union victory, it did not move them any closer to Vicksburg.

The Battle of Big Black River Bridge was fought on May 17, 1863, as part of the Vicksburg Campaign of the American Civil War. After a Union army commanded by Major General Ulysses S. Grant defeated Lieutenant General John C. Pemberton's Confederate army at the Battle of Champion Hill on May 16, Pemberton ordered Brigadier General John S. Bowen to hold a rear guard at the crossing of the Big Black River to buy time for the Confederate army to regroup. Union troops commanded by Major General John McClernand pursued the Confederates, and encountered Bowen's rear guard. A Union charge quickly broke the Confederate position, and during the retreat and river crossing, a rout ensued.

The Battle of Champion Hill of May 16, 1863, was the pivotal battle in the Vicksburg Campaign of the American Civil War (1861–1865). Union Army commander Maj. Gen. Ulysses S. Grant and the Army of the Tennessee pursued the retreating Confederate States Army under Lt. Gen. John C. Pemberton and defeated it twenty miles to the east of Vicksburg, Mississippi, leading inevitably to the siege of Vicksburg and surrender. The battle is also known as Baker's Creek.

The Battle of Chickasaw Bayou, also called the Battle of Walnut Hills, fought December 26–29, 1862, was the opening engagement of the Vicksburg Campaign during the American Civil War. Confederate forces under Lt. Gen. John C. Pemberton repulsed an advance by Union Maj. Gen. William T. Sherman that was intended to lead to the capture of Vicksburg, Mississippi.

The following Confederate Army units and commanders fought in the Battle of Raymond; the Union order of battle is listed separately.

The Battle of Grand Gulf was fought on April 29, 1863, during the American Civil War. As part of Major General Ulysses S. Grant's Vicksburg campaign, seven Union Navy ironclad warships commanded by Admiral David Dixon Porter bombarded Confederate fortifications at Grand Gulf, Mississippi. One of the Confederate fortifications, named Fort Wade, was silenced, but the other, named Fort Cobun, continued firing. Due to the strong Confederate resistance, Grant and Porter decided it was not feasible to make an amphibious landing at Grand Gulf, but later landed at Bruinsburg, Mississippi, instead. After the Confederates were defeated at the Battle of Port Gibson on May 1, Grand Gulf was rendered indefensible and the fortifications were abandoned. The defenders of Grand Gulf then fought at the Battle of Champion Hill on May 16 and the Battle of Big Black River Bridge on May 17, before the start of the Siege of Vicksburg, which ended with a Confederate surrender on July 4. Today, the battlefield is preserved in Grand Gulf Military State Park, which was listed on the National Register of Historic Places in 1972.

Grant's Canal was an incomplete military effort to construct a canal through De Soto Point in Louisiana, across the Mississippi River from Vicksburg, Mississippi. During the American Civil War, United States Navy forces attempted to capture the city of Vicksburg in 1862, but were unable to do so with army support. Union Brigadier General Thomas Williams was sent to De Soto Point with 3,200 men to dig a canal capable of bypassing the strong Confederate defenses around Vicksburg. Despite help from local plantation slaves, disease and falling river levels prevented Williams from successfully constructing the canal, and the project was abandoned until January 1863, when Union Major General Ulysses S. Grant took an interest in the project.

Grierson's Raid was a Union cavalry raid during the Vicksburg Campaign of the American Civil War. It ran from April 17 to May 2, 1863, as a diversion from Maj. Gen. Ulysses S. Grant's main attack plan on Vicksburg, Mississippi.

The Battle of Helena, also known as the Attack on Helena, was a battle of the American Civil War fought on July 4, 1863, in Helena, Arkansas. The battle was a failed Confederate attempt to relieve pressure on the besieged city of Vicksburg. The Union victory at Helena paved the way for the fall of Little Rock.

The Battle of Jackson was fought on May 14, 1863, in Jackson, Mississippi, as part of the Vicksburg campaign during the American Civil War. After entering the state of Mississippi in late April 1863, Major General Ulysses S. Grant of the Union Army moved his force inland to strike at the strategic Mississippi River town of Vicksburg, Mississippi. The Battle of Raymond, which was fought on May 12, convinced Grant that General Joseph E. Johnston's Confederate army was too strong to be safely bypassed, so he sent two corps, under Major Generals James B. McPherson and William T. Sherman, to capture Johnston's position at Jackson. Johnston did not believe the city was defensible and began withdrawing. Brigadier General John Gregg was tasked was commanding the Confederate rear guard, which fought Sherman's and McPherson's men at Jackson on May 14 before withdrawing. After taking the city, Union troops destroyed economic and military infrastructure and also plundered civilians' homes. Grant then moved against Vicksburg, which he placed under siege on May 18 and captured on July 4. Despite being reinforced, Johnston made only a weak effort to save the Vicksburg garrison, and was driven out of Jackson a second time in mid-July.
The Battle of Lake Providence was an engagement that was fought between Confederate and Union forces near Lake Providence, Louisiana on June 9, 1863, during the Vicksburg Campaign of the American Civil War.

McRaven was built c. 1797 by Andrew Glass in a town called Walnut Hills, which is now Vicksburg, Mississippi. In the Civil War era, it was known as the Bobb House, and it is listed on the National Register of Historic Places as such. McRaven got its current name from the street it is located on, which was formerly called McRaven Street, but is now Harrison Street. McRaven has been on the Mississippi Department of Archives and History's Historic Preservation list since January 8, 1978. It is also believed by many to be haunted, and has been called "the most haunted house in Mississippi."

The Battle of Milliken's Bend was fought on June 7, 1863, as part of the Vicksburg Campaign during the American Civil War. Major General Ulysses S. Grant of the Union Army had placed the strategic Mississippi River city of Vicksburg, Mississippi, under siege in mid-1863. Confederate leadership erroneously believed that Grant's supply line still ran through Milliken's Bend in Louisiana, and Major General Richard Taylor was tasked with disrupting it to aid the defense of Vicksburg. Taylor sent Brigadier General Henry E. McCulloch with a brigade of Texans to attack Milliken's Bend, which was held by a brigade of newly-recruited African American soldiers. McCulloch's attack struck early on the morning of June 7, and was initially successful in close-quarters fighting. Fire from the Union gunboat USS Choctaw halted the Confederate attack, and McCulloch later withdrew after the arrival of a second gunboat. The attempt to relieve Vicksburg was unsuccessful. One of the first actions in which African American soldiers fought, Milliken's Bend demonstrated the value of African American soldiers as part of the Union Army.

The Mississippi Marine Brigade was a Union Army amphibious unit which included the United States Ram Fleet and operated from November 1862 to August 1864 during the American Civil War. The brigade was established to act swiftly against Confederate forces operating near the Mississippi River and its tributaries. The brigade was commanded by Brigadier General Alfred W. Ellet and operated in coordination with the Mississippi River Squadron during the Union brown-water navy battle against the Confederate River Defense Fleet and land based forces. The brigade was independent of the Union Army and Navy and reported directly to the Secretary of War, Edwin M. Stanton. Despite the name, it was never part of the United States Marine Corps.

The Battle of Port Gibson was fought near Port Gibson, Mississippi, on May 1, 1863, between Union and Confederate forces during the Vicksburg Campaign of the American Civil War. The Union Army was led by Maj. Gen. Ulysses S. Grant, and was victorious.

The Battle of Raymond was fought on May 12, 1863, near Raymond, Mississippi, during the Vicksburg Campaign of the American Civil War. After unsuccessful attempts to capture the strategic Mississippi River city of Vicksburg, Major General Ulysses S. Grant of the Union Army led another attempt, beginning in late April 1863. After crossing the river into Mississippi and winning the Battle of Port Gibson, Grant began moving east, with the intention of later turning west and attacking Vicksburg. As part of this movement, Major General James B. McPherson's 10,000 to 12,000-man XVII Corps moved towards Raymond. The Confederate commander of Vicksburg, Lieutenant General John C. Pemberton ordered Brigadier General John Gregg and his 3,000 to 4,000-strong brigade from Jackson to Raymond.

The siege of Vicksburg was the final major military action in the Vicksburg campaign of the American Civil War. In a series of maneuvers, Union Maj. Gen. Ulysses S. Grant and his Army of the Tennessee crossed the Mississippi River and drove the Confederate Army of Mississippi, led by Lt. Gen. John C. Pemberton, into the defensive lines surrounding the fortress city of Vicksburg, Mississippi.

The Battle of Snyder's Bluff or Snyder's Mill was fought from April 29 to May 1, 1863, during the Vicksburg Campaign of the American Civil War. Union forces under Maj. Gen. William T. Sherman conducted a feint against Confederate units holding the bluff, which was easily repelled.

The Steele's Bayou expedition was a joint operation of Major General Ulysses S. Grant's Army of the Tennessee and Rear Admiral David D. Porter's Mississippi River Squadron, conducted as a part of the Vicksburg Campaign of the American Civil War. Its aim was to move Union forces from the Mississippi River to a point on the Yazoo River upstream of Confederate Lieutenant General John C. Pemberton's defenses of Vicksburg. To avoid enemy artillery in place on the bluffs to the east of the city, the expedition would leave the Yazoo and proceed indirectly on a route through a series of waterways in the flood plain to the east of the Mississippi.

The United States Ram Fleet was a Union Army unit of steam powered ram ships during the American Civil War. The unit was independent of the Union Army and Navy and reported directly to the Secretary of War, Edwin M. Stanton. The ram fleet operated in coordination with the Mississippi River Squadron during the Union brown-water navy battle against the Confederate River Defense Fleet for control of the Mississippi River and its tributaries.

The Yazoo Pass expedition was a joint operation of Major General Ulysses S. Grant's Army of the Tennessee and Rear Admiral David D. Porter's Mississippi River Squadron in the Vicksburg campaign of the American Civil War. Grant's objective was to get his troops into a flanking position against the Rebel defenders. The expedition was an effort to bypass the Confederate defenses on the bluffs near the city by using the backwaters of the Mississippi Delta as a route from the Mississippi River to the Yazoo River. Once on the Yazoo, the Army would be able to cross the river unopposed and thus achieve their goal. The operation would require a deep penetration into enemy territory that was dominated by water, so cooperation between the two services was necessary. The Army was led by Brigadier General Leonard F. Ross. Naval commander was Lieutenant Commander Watson Smith, who was in extremely poor health; his health was an important factor in the ultimate failure of the expedition.
