The Battle of Snyder's Bluff was fought from April 29 to May 1, 1863, during the Vicksburg Campaign of the American Civil War. Federal Major General Ulysses S. Grant had decided to move most of his army down the west bank of the Mississippi River and then cross south of Vicksburg, Mississippi, at Grand Gulf as part of his campaign against the city. To cover his planned crossing, Major General William T. Sherman took Francis P. Blair Jr.'s division of his XV Corps on a maneuver up the Yazoo River to feint at Confederate defenses at Snyder's Bluff and Drumgould's Bluff.

Contents

Along with a naval force commanded by Lieutenant Commander K. Randolph Breese, Sherman's men entered the Yazoo River on April 29, and the next day approached the Confederate defenses. Breese's ships bombarded the Confederate defenses in the morning, while in the afternoon, a land assault accomplished little and failed to convince the Confederates that the Yazoo River expedition was anything more than a distraction. On May 1, more infantry probes were made, but Sherman received orders from Grant to return to the main Federal force as a result of operations in the Grand Gulf area. A gunboat bombardment on the afternoon of May 1 caused more damage than the previous day's. The operation failed to convince the Confederates that it was anything more than a feint. While reinforcements to Grand Gulf were delayed, this was not caused by Sherman's operation. Federal naval element had been unable to silence Confederate defenses at Grand Gulf in the Battle of Grand Gulf on April 29, but Grant simply moved his crossing further downriver. The campaign ended in a Federal victory on July 4 and represented a major turning point in the war.

Grant's Operations against Vicksburg
  Confederate
  Federal

Early in the American Civil War, Federal military leadership developed the Anaconda Plan, which was a strategy to defeat the Confederate States of America. A significant component of this strategy was controlling the Mississippi River. [1] Much of the Mississippi Valley fell under Federal control in early 1862 after the capture of New Orleans, Louisiana, and several land victories. [2] The strategically important city of Vicksburg, Mississippi, was still in Confederate hands, serving as both a strong defensive position by commanding the river and as the linchpin between the two halves of the Confederacy. Federal Navy elements were sent upriver from New Orleans in May to try to take the city, a move that was ultimately unsuccessful. [3] In late June, a joint army-navy expedition returned to make another campaign against Vicksburg. [4] Federal Navy leadership decided that the city could not be taken without more infantrymen, who were not forthcoming. An attempt to cut a canal across a meander of the river, bypassing Vicksburg, failed. [5] [6]

In late November, about 40,000 Federal 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 Federal attack on December 29 was defeated decisively at the Battle of Chickasaw Bayou, and Sherman's men withdrew on January 1, 1863. [7]

Prelude

By late March, further attempts to bypass Vicksburg had failed. [8] Grant then considered three plans: to withdraw to Memphis and retry the overland route through northern Mississippi; to move south along the west side of the Mississippi River, cross below Vicksburg, and then strike for the city; or to make an amphibious assault across the river against Vicksburg. An assault across the river risked heavy casualties, and a withdrawal to Memphis could be politically disastrous if the public perceived such a movement as a retreat. Grant then decided upon the downstream crossing. [9] The advance along the west bank of the Mississippi began on March 29, and was spearheaded by Major General John A. McClernand's troops. [10] The movement down the river was masked by decoy operations such as Steele's Greenville expedition, [11] Streight's Raid, and Grierson's Raid. [12] Confederate regional commander John C. Pemberton fell for the Federal decoys (especially Grierson's Raid), and lost touch with the true tactical situation, believing Grant was withdrawing. [13]

By late April, McClernand's men had made the march downriver, and Major General James B. McPherson's men were on the way. [14] Major General William T. Sherman's XV Corps was intended to follow later, [15] but, on April 27, Grant changed his plan for Sherman's men. An attack at Grand Gulf, Mississippi, followed by an amphibious crossing by McClernand's corps, was planned for April 29, and Grant wanted to divert Confederate attention away from the crossing attempt. Sherman and a detachment from the XV Corps were to, if practical, approach Confederate defensive works 12 miles (19 km) northeast of Vicksburg at Snyder's Bluff and conduct a feint. [14] Grant expressed some hesitancy about the feint, and left final judgment to Sherman; Grant feared that the failure of the mock attack would be viewed by the Northern public as another Chickasaw Bayou-style defeat. Unconcerned about the opinions of the press, Sherman decided to continue on. [16] However, Sherman carried some doubts about Grant's overall plan, fearing that it might be necessary for Sherman to take his whole corps downriver and bail out Grant in case of failure. [17]

Rear Admiral David Dixon Porter delegated responsibility for the naval portion of the operations to Lieutenant Commander K. Randolph Breese. Breese supported the operation, but wanted to wait for the arrival of the ironclad USS Choctaw. Waiting on April 28 for Choctaw to arrive, Major General Francis P. Blair Jr.'s division was issued three days' rations and 60 rounds of ammunition. At about 5:00 pm, Choctaw arrived, and the expedition set off the next morning. [18] Transportation up the Yazoo River was provided by ten troops transports, [19] six of whom had ersatz defensive works made of hay bales on their decks. Those six transports each mounted two cannon, drawn from Battery A, 1st Illinois Light Artillery Regiment and Battery B, 1st Illinois Light Artillery Regiment. [20] The transports were escorted by a group of 11 naval ships: [21] the flagship USS Black Hawk, Choctaw, the ironclad USS Baron DeKalb, the timberclad USS Tyler, the tinclads USS Romeo, USS Linden, USS Signal, and USS Petrel, and three mortar scows. [22]

The vessels reached the junction of Chickasaw Bayou and the Yazoo River on the afternoon of April 29, and stopped for the night, in the vicinity of the old Chickasaw Bayou battlefield. [23] The next morning, the convoy resumed its movement, although Petrel was left behind as a guard, to prevent Confederates from placing naval mines in the river. Firing began at about 10:00 am, when Baron DeKalb and Choctaw opened fire on Confederate positions at Drumgould's Bluff, a bluff located 1 mile (1.6 km) downriver from Snyder's Bluff. Black Hawk and Tyler also opened fire, and the mortar scows positioned themselves and opened fire. Linden guarded the mortar scows, while Romeo and Signal remained in the rear in a supporting position. [24] The Confederate defenses in the area were commanded by Brigadier General Louis Hébert, [23] and contained 16 heavy cannon. Defensive entrenchments were also present at the position. [25] A raft had previously been constructed near Snyder's Bluff to block passage up the river, but it had washed out on April 26. [23]

The Federal ironclads were at a disadvantage, as they could only fire their broadside guns due to ships' positioning. [26] Hébert wanted to prevent the Federals from learning of his positions too quickly, and so he delayed ordering his guns to open fire. Once the Confederates opened fire, the largest guns could only target Choctaw, although some of the other cannon were able to fire at other targets. Tyler was damaged by a shot from a 12-pounder Whitworth rifle and had to withdraw, while Choctaw took 47 hits without serious damage. Some men from the 3rd Louisiana Infantry Regiment attempted to harass Baron DeKalb, but were driven off by a landing party from the vessel. [27] During the artillery bombardment, Federal soldiers landed on shore and attempted to corral cattle, causing a stampede. [25]

The Federal gunboats withdrew, and Hébert found that only two of his men had been wounded during the bombardment, and that the defenses had not suffered serious damage. [28] During the afternoon, some of Blair's men landed. [25] Due to flooding, the infantrymen were only able to advance over the path of a levee. The Federals came under fire from the 3rd Louisiana and Confederate artillery, and were prevented from further advancing. [28] The Federal mock attack had not been convincing, and the Confederates suspected that it might be a demonstration. [25]

On the morning of May 1, Sherman landed the 8th Missouri Infantry Regiment on the west side of the river, but a bayou and Confederate artillery fire from across the river forced them to withdraw. Two other Federal regiments scouted Drumgould's Bluff, and learned that the Confederates had strengthened their positions. Sherman and Breese held a conference, and decided to resume gunboat fire at 3:00 pm. However, Sherman received an urgent message that Grant had written on April 29. The note informed Sherman that the Federals had passed Grand Gulf, and that Sherman needed to put two of his divisions on the move for the campaign. [29] Sherman responded by placing Blair in charge of the Snyder's Bluff operations, ordering one of his divisions to guard the Young's Point, Louisiana, to Richmond, Louisiana, corridor, and mobilizing the other two on the march south. [25]

At around 3:00 pm, Breese had Tyler, Choctaw, and Black Hawk move upriver to shell the Confederate positions, while Baron DeKalb fired from further downstream. Two Confederate guns were knocked out of action, and the Federal fire was more effective. Around dark, the Federals broke off the engagement. Blair's men moved out of the area on transports at around 8:00 pm, and the gunboats followed. Hébert reported that he had suffered no casualties in the day's fighting, while Tyler was the only Federal ship to have been struck during the exchange. [30]

Aftermath

While Sherman later exaggerated the importance of the operation in his memoirs, Bearss writes that "Sherman's activities on the Yazoo made little impression on the Confederates who opposed them". [31] While the Confederates delayed reinforcing Grand Gulf, this would have occurred even without Sherman's feint, [25] largely due to poor performance by Confederate officers Pemberton and Carter L. Stevenson. [32] Confederate officers at the bluff recognized the attack as a demonstration, although Miller writes that "Sherman's presence on the Yazoo did create further confusion about [Federal] intentions". [21] The historians William L. Shea and Terrence J. Winschel write that the Snyder's Bluff demonstration is an example of Grant's commitment to actions designed to distract the Confederates during the campaigns against Vicksburg. [33]

On April 29, Porter's gunboats had bombarded the Confederate positions at Grand Gulf in the Battle of Grand Gulf, but were unable to silence all of the Confederate guns. In response, Grant simply moved his crossing downriver from Grand Gulf to Bruinsburg, Mississippi. [34] On May 1, Grant's lead elements defeated a Confederate force in the Battle of Port Gibson, opening the route to inland Mississippi. [35] Grant changed his approach march to Vicksburg after the Battle of Raymond, moving towards Jackson, Mississippi, and then capturing the city. [36] The defenders of Vicksburg fought Grant east of Vicksburg in the Battle of Champion Hill on May 16, but were defeated. [37] Grant began the Siege of Vicksburg on May 18, and the Confederate surrendered the river town on July 4, marking a major turning point in the war. [38]

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 Major General Ulysses S. Grant and his Army of the Tennessee crossed the Mississippi River and drove the Confederate Army of Mississippi, led by Lieutenant General John C. Pemberton, into the defensive lines surrounding the fortress city of Vicksburg, Mississippi, leading to the successful siege and Confederate surrender.

<span class="mw-page-title-main">Battle of Arkansas Post (1863)</span> Part of the American Civil War

The Battle of Arkansas Post, also known as Battle of Fort Hindman, was fought from January 9 to 11, 1863, along the Arkansas River at Arkansas Post, Arkansas, as part of the Vicksburg campaign of the American Civil War. Confederate forces had constructed a fort known as Fort Hindman near Arkansas Post in late 1862. Also in late 1862, Major General John A. McClernand of the Union Army was authorized to recruit troops in the midwest in preparation for an expedition down the Mississippi River against Vicksburg, Mississippi. Union Major General Ulysses S. Grant began an overland campaign against Vicksburg along the Mississippi Central Railroad in November. Grant and Major General Henry Halleck did not trust McClernand, and machinated start the riverine movement south against Vicksburg under the command of Major General William T. Sherman before McClernand could arrive. Sherman's movement was defeated in the Battle of Chickasaw Bayou in late December, and Confederate cavalry raids forced Grant to abandon his overland campaign.

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 with 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.

<span class="mw-page-title-main">Battle of Milliken's Bend</span> Battle of the American Civil War

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, 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 Battle of Big Black River Bridge was fought on May 17, 1863, as part of the Vicksburg Campaign of the American Civil War. During the war, the city of Vicksburg, Mississippi, was a key point on the Mississippi River. On April 30, 1863, a Union army commanded by Major General Ulysses S. Grant began crossing onto the east side of the Mississippi River as part of a campaign against Vicksburg. After engaging and defeating Confederate forces in several intermediate battles, Grant's army defeated Lieutenant General John C. Pemberton's troops at the decisive Battle of Champion Hill on May 16. During the retreat from Champion Hill battlefield, one division of Pemberton's army, commanded by Major General William W. Loring, was cut off from Pemberton's main body. Pemberton, retreating westwards towards Vicksburg, did not know the location of Loring's division, and he held a bridgehead on the east side of the Big Black River to cover Loring's anticipated withdrawal across the river on the morning of May 17.

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, the Union Navy attempted to capture the Confederate-held 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 defenses around Vicksburg. Despite being assisted by locally enslaved people, Williams was unable to finish constructing the canal due to disease and falling river levels, and the project was abandoned until January 1863, when Union Major-General Ulysses S. Grant took an interest in the project.

<span class="mw-page-title-main">Battle of Raymond</span> 1863 battle of the American Civil War

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.

USS <i>Marmora</i> (1862) Gunboat of the United States Navy

USS Marmora was a sternwheel steamer that served in the Union Navy from 1862 to 1865, during the American Civil War. Built in 1862 at Monongahela, Pennsylvania, as a civilian vessel, she was purchased for military service on September 17 and converted into a tinclad warship. Commissioned on October 21, the vessel served on the Yazoo River beginning the next month. She encountered Confederate naval mines on the Yazoo on December 11, and was present the next day when the ironclad USS Cairo was sunk by two mines. After further service on the Yazoo during the Battle of Chickasaw Bayou in late December, Marmora was assigned in January 1863 to a fleet that was preparing to operate against Confederate Fort Hindman, but was not present when the fort surrendered on January 11.

<span class="mw-page-title-main">Battle of Grand Gulf</span> 1863 battle of the American Civil War

The Battle of Grand Gulf was fought on April 29, 1863, during the American Civil War. Union Army forces commanded by Major General Ulysses S. Grant had failed several times to bypass or capture the Confederate-held city of Vicksburg, Mississippi, during the Vicksburg campaign. Grant decided to move his army south of Vicksburg, cross the Mississippi River, and then advance on the city. A Confederate Army division under Brigadier General John S. Bowen prepared defenses—Forts Wade and Cobun—at Grand Gulf, Mississippi, south of Vicksburg. To clear the way for a Union crossing, seven Union Navy ironclad warships from the Mississippi Squadron commanded by Admiral David Dixon Porter bombarded the Confederate defenses at Grand Gulf on April 29. Union fire silenced Fort Wade and killed its commander, but the overall Confederate position held. Grant decided to cross the river elsewhere.

USS <i>Indianola</i> American casemate ironclad

USS Indianola was a casemate ironclad that served as a river gunboat for the Union Navy during the American Civil War. A side-wheel steamer also equipped with two screw propellers, Indianola was built in Cincinnati, Ohio in 1862 by Joseph Brown before being taken by Union authorities while still incomplete, in response to a perceived Confederate threat to Cincinnati. After completion, the vessel briefly served on the Mississippi River and the Yazoo River before being sent downstream of Vicksburg, Mississippi in February 1863, to support the naval ram USS Queen of the West, which was operating against Confederate shipping.

Major General John George Walker's division of Confederate troops, known as Walker's Greyhounds had attacked Union forces in the Battle of Milliken's Bend and the Battle of Lake Providence earlier that month in hopes of relieving some of the pressure on the Confederate troops besieged in Vicksburg, Mississippi. While both of Walker's strikes were failures and the Confederates withdrew to Richmond, Union Major General Ulysses S. Grant still viewed the presence of Walker's men at Richmond to be a threat. On June 14, the Mississippi Marine Brigade and the infantry brigade of Brigadier General Joseph A. Mower were sent to attack the Confederates at Richmond.

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.

Early the next year, the ram USS Queen of the West moved downriver to interfere with Confederate shipping on the Red River; Indianola was sent down a few days later. However, Queen of the West was disabled and captured after an encounter with Confederate field fortifications, and Indianola was severely damaged on February 24 after an attack by the repaired Queen of the West and CSS William H. Webb.

<span class="mw-page-title-main">Duckport Canal</span> American Civil War waterway in Louisiana

The Duckport Canal was an unsuccessful military venture by Union forces during the Vicksburg campaign of the American Civil War. Ordered built in late March 1863 by Major General Ulysses S. Grant, the canal stretched from the Mississippi River near Duckport, Louisiana, to New Carthage, Louisiana, and utilized a series of swampy bayous for much of its path. It was intended to provide a water-based supply route for a southward movement against the Confederate-held city of Vicksburg, Mississippi, as high water levels made overland travel difficult. Manual digging was provided by 3,500 soldiers from Grant's army and was finished on April 12. The next day, the levee separating the canal cut and the Mississippi River was breached, and water flowed into the canal. Trees that had grown up in the bayous and falling water levels that reached as shallow as 6 inches (15 cm) at one point hampered the use of the canal, and the project was abandoned on May 4. Grant moved men and supplies through the overland route, which had been made more accessible by the same falling water levels that doomed the canal. After some inland maneuvering and a lengthy siege, Vicksburg surrendered on July 4, marking a significant turning point in the war.

<span class="mw-page-title-main">Steele's Greenville expedition</span> American Civil War operation in Mississippi

Steele's Greenville expedition took place from April 2 to 25, 1863, during the Vicksburg campaign of the American Civil War. Union forces commanded by Major General Frederick Steele occupied Greenville, Mississippi, and operated in the surrounding area, to divert Confederate attention from a more important movement made in Louisiana by Major General John A. McClernand's corps. Minor skirmishing between the two sides occurred, particularly in the early stages of the expedition. Over 1,000 slaves were freed during the operation, and large quantities of supplies and animals were destroyed or removed from the area. Along with other operations, including Grierson's Raid, Steele's Greenville expedition distracted Confederate attention from McClernand's movement. Some historians have suggested that the Greenville expedition represented the Union war policy's shifting more towards expanding the war to Confederate social and economic structures and the Confederate homefront.
