Grierson's Raid

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.[1][2]

Operations against Vicksburg, including Grierson's Raid.

Early in 1863, Major General Charles Hamilton, the commander of the Corinth section of Grant's division, suggested what would eventually become Grierson's Raid. Subsequently, due to Hamilton's insistence on procuring a command that would garner him more glory, Hamilton offered his resignation. Grant quickly accepted.[3]

In the Western Theater of the American Civil War, Confederate cavalry raids under commanders such as Lt. Gen. Nathan Bedford Forrest and Brig. Gen. John Hunt Morgan had harassed Union expeditions, namely at the Battle of Parker's Crossroads, where Forrest captured three hundred Union soldiers under Brig. Gen. Jeremiah C. Sullivan, but lost all of the artillery pieces belonging to his own command.[4] The task of drawing the attention of Confederate raiders away from the Siege of Vicksburg fell to Col. Benjamin Grierson, a former music teacher who, oddly, hated horses after being kicked in the head by one as a child. Grierson's cavalry brigade consisted of the 6th and 7th Illinois and 2nd Iowa Cavalry regiments.

The raidEdit

Grierson and his 1,700 horse troopers, some in Confederate uniforms serving as scouts for the main force, rode over 600 miles (970 km) through hostile territory (from southern Tennessee, through the state of Mississippi and into Union-held Baton Rouge, Louisiana), over routes no Union soldier had traveled before. They tore up railroads and burned crossties, freed slaves, burned Confederate storehouses, destroyed locomotives and commissary stores, ripped up bridges and trestles, burned buildings, and inflicted ten times the casualties they received, all while detachments of his troops made feints confusing the Confederates as to his actual whereabouts, intent and direction. Total casualties for Grierson's Brigade during the raid were three killed, seven wounded, and nine missing. Five sick and wounded men were left behind along the route, too ill to continue.

Confederate Lt. Gen. John C. Pemberton, commander of the Vicksburg garrison, had few cavalry and could do nothing to stop Grierson.

Grierson's raiders.

On April 21, 1863, Confederate cavalry commander Maj. Gen. Nathan Bedford Forrest, had captured another Union raider, Col. Abel Streight, in Alabama following a poorly supplied and poorly planned raid.[5][circular reference]

While Streight's Raid failed, Forrest allowed Grierson to raid through Mississippi unopposed by his own forces for over two weeks. Although many other Confederate cavalry units pursued Grierson vigorously across the state (most notably those led by Wirt Adams and Robert V. Richardson), they were unsuccessful in stopping the raid.[1] Grierson and his troopers, exhausted by weeks in the saddle, ultimately rode into Union-occupied Baton Rouge, Louisiana.[6] With an entire division of Pemberton's soldiers tied up defending the vital Vicksburg-Jackson railroad from the evasive Grierson, combined with Maj. Gen. William T. Sherman's feint northeast of Vicksburg (the Battle of Snyder's Bluff), the beleaguered Confederates were unable to muster the forces necessary to oppose Grant's eventual landing below Vicksburg on the east side of the Mississippi at Bruinsburg.

In popular mediaEdit

The movie The Horse Soldiers, directed by John Ford, and starring John Wayne, William Holden and Constance Towers, and the Harold Sinclair novel of the same name on which it is based, are fictional variations of Grierson's Raid.
