The Battle of Raymond was fought on May 12, 1863, near Raymond, Mississippi, during the Vicksburg campaign of the American Civil War. Initial Union attempts to capture the strategically important Mississippi River city of Vicksburg failed. Beginning in late April 1863, Union Major General Ulysses S. Grant led another try. After crossing the river into Mississippi and winning the Battle of Port Gibson, Grant began moving east, intending to turn back west and attack Vicksburg. A portion of Grant's army consisting of Major General James B. McPherson's 10,000 to 12,000-man XVII Corps moved northeast 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.
Gregg's brigade contacted the leading elements of McPherson's corps on May 12. Neither commander was aware of the strength of his opponent, and Gregg acted aggressively, thinking McPherson's force was small enough that his men could easily defeat it. McPherson, in turn, overestimated Confederate strength and responded cautiously. The early portions of the battle pitted two brigades of Major General John A. Logan's division against the Confederate force, and the battle was matched relatively evenly. Eventually, McPherson brought up Brigadier General John D. Stevenson's brigade and Brigadier General Marcellus M. Crocker's division. The weight of superior Union numbers eventually began to crack the Confederate line, and Gregg decided to disengage. McPherson's men did not immediately pursue.
The battle at Raymond changed Grant's plans for the Vicksburg campaign, leading him to first focus on neutralizing the Confederate forces at Jackson before turning against Vicksburg. After successfully capturing Jackson, Grant's men pivoted west, drove Pemberton's force into the defenses of Vicksburg, and forced a Confederate surrender on July 4, ending the Siege of Vicksburg. The site of the Battle of Raymond was added to the National Register of Historic Places in 1972, and public interpretation of a portion of the site is provided by the Friends of Raymond. Historians Ed Bearss, Michael Ballard, and Timothy B. Smith have criticized McPherson's handling of the battle.
Background
Early in the Civil War, Union military leadership developed the Anaconda Plan, which was a strategy to defeat the Confederate States of America (a significant component of which was controlling the Mississippi River.) Much of the Mississippi Valley fell under Union control in early 1862 after the capture of New Orleans, Louisiana, and several land victories. The strategically important city of Vicksburg, Mississippi was still in Confederate hands, serving both as a strong defensive position by commanding the river and as the linchpin between the two halves of the Confederacy. Union Navy elements were sent upriver from New Orleans in May to try to take the city, a move that was ultimately unsuccessful. In late June, a joint army-navy expedition returned to make another campaign against Vicksburg. Union Navy leadership decided that the city could not be taken without more infantrymen, who were not forthcoming. An attempt to dig a canal across a meander of the river, bypassing Vicksburg, failed.
In late November, about 40,000 Union infantry commanded by Major General Ulysses S. Grant began moving south towards Vicksburg from a starting point in Tennessee. Grant ordered a retreat after a supply depot and part of his supply line were destroyed during the Holly Springs Raid and Forrest's West Tennessee Raid. Meanwhile, another arm of the expedition under the command of Major General William T. Sherman left Memphis, Tennessee on the same day as the Holly Springs Raid and traveled down the Mississippi River. After diverting up the Yazoo River, Sherman's men began skirmishing with Confederate soldiers defending a line of hills above the Chickasaw Bayou. A Union attack on December 29 was defeated decisively at the Battle of Chickasaw Bayou, and Sherman's men withdrew on January 1, 1863.
