The Overland Campaign

The Overland Campaign was a series of military engagements in the Eastern Theater of the War from May 4-June 12, 1864. It is also referred to by several other names including Grant's Overland Campaign, the Wilderness Campaign, the Rapidan Campaign, the Expedition up the James River, and the Campaign from the Rapidan (River) to the James (River).
Union Lieutenant General Ulysses S. Grant, the general-in-chief of all Union armies, sought to put the Union Army of the Potomac between General Robert E. Lee's Army of Northern Virginia and the Confederate capital at Richmond, Virginia. Acting through Major General George Gordon Meade, Grant hopes his superior numbers in open battle will be enough to overcome Lee, but a surprise attack by Lee sets the tone for the rest of the campaign. Movement after movement is made to work around Lee's left flank and every time Lee beats Grant to the next battlefield. Despite heavy casualties, Grant edges closer to achieving the ultimate Union objective.
On May 4, 1864, General Grant crossed the Rapidan River hoping to invite Lee to open battle where his numbers could be easily reduced. Lee surprised Grant by attacking the larger Union army aggressively in the first days of the campaign at the Battle of the Wilderness (May 5-7), resulting in confused fighting and heavy casualties on both sides. Undeterred, Grant broke tradition with his command predecessors and devised a plan to continue towards Richmond despite the losses. Lee again predicted Grant's movements and fortified positions at Spotsylvania Courthouse (May 8–21). Grant repeatedly hammered the Confederate line for two weeks and failed to break through Confederate lines, suffering heavy losses on the field.
Grant again wheeled his forces (and again Lee met them) at the North Anna River (May 23–26). Although Lee's army held strong defensive positions with potential to defeat large portions of Grant's army, illness prevented him from fully executing these plans in time for Grant's final shift south towards Richmond. Grant mistakenly believed that Confederate forces had been sufficiently worn down and that several all-out assaults at Cold Harbor (May 31-June 12) would decisively break Confederate lines. Instead, Confederate positions proved strong enough to repel a Union assault a 7-mile front and inflict disproportionately heavy casualties on the attacking Union forces. In one final maneuver of stealth, Grant crossed the James River and set the stage for one of the ultimate campaigns of the war - a 10 month siege against the Confederate
rail depot and supply hub at Petersburg. The fall of this city in the final stages of the Richmond Campaign dooms the Confederate capital, and eventually, the Confederate nation.
The campaign also included two long-range raids by the Union Cavalry Corps under Major General Philip Sheridan. In the first raid towards Richmond, Union forces were able to mortally wound Confederate Major General J.E.B. Stuart at Yellow Tavern. In the second raid, Confederate Major General Wade Hampton thwarted Sheridan's designs to destroy the Virginia Central Railroad at Trevillian Station, the largest all-cavalry battle of the war. Sheridan's raids were somewhat successful in distracting Confederate troops and disrupting supply lines, but often deprived the Union of key cavalry resources in larger operations of the campaign.
== Prologue ==
In March 1864, President Lincoln summoned General Grant to the Eastern Theater and promoted him to Lieutenant General, in charge of all Union armies. He made his headquarters with the Army of the Potomac and coordinated the overall war effort where this army went. Meade retained formal command of the Army of the Potomac, and Sherman succeeded Grant in command of most of the Western troops. 
Grant and President Lincoln devised a strategy to move against Confederate armies at once, the first concentrated effort of the war to do so. By keeping all major Confederate forces on the defensive, the Union command hoped that reinforcements could not be shipped by rail from one field to another on the Confederacy's internal railroad lines:
* Grant and Meade would take the Army of the Potomac and operate against Lee near Richmond
* Benjamin Butler would take the Army of the James and push to Richmond from the nearby Bermuda Hundred
* Franz Sigel would move against Confederate forces in the Shenandoah Valley
* Sherman would invade Georgia and engage Joseph E. Johnston's army 
* George Crook and William W. Averell would operate against railroad supply lines in West Virginia
* Nathaniel Banks would move to capture Mobile, Alabama
This campaign also differed from previous campaigns in Virginia in that the capture of Richmond was not the primary objective. Whereas the aim of previous campaigns had been simply to seize the capital and force a Confederate surrender, Lincoln had long believed that the primary army defending the city needed to be destroyed, and only then could the city fall to Union control. Grant ordered Meade, "Wherever Lee goes, there you will go also," giving similar instructions to Sherman in Georgia.Hattaway & Jones, p. 525; Trudeau, pp. 29–30. 
Grant hoped to lure Lee's army into combat on a open field, where superior northern numbers could crush the Army of Virginia. However, his experiences in the war thus far had shown that this would not be so simple. Grant prepared for a much longer campaign against southern forces, intending to "hammer continuously against the armed force of the enemy and his resources until by mere attrition, if in no other way, there should be nothing left to him but an equal submission with the loyal section of our common country to the constitution and laws of the land."Rhea, Wilderness, pp. 46–47; Eicher, pp. 661–62. McPherson, p. 734 Grant could replace his casualties; Lee could not.
== Opposing Forces ==
=== Union Order of Battle ===
Even though Grant had superior numbers available to him, his campaign to Richmond faced several logistical and personnel challenges. The 1st Corps and 3rd Corps units had been disbanded or redistributed to other corps following their valiant but devastating actions at Gettysburg the previous year, damaging army cohesion and morale. Further, the enlistment terms of many regiments would expire during the campaign, eventually forcing a reorganization of those higher commands and a reluctance of those units to participate in major assaults. Other units were brought in to replace those leaving, many during the battles of Cold Harbor, as well as an additional corps of the Army of the James previously occupied at the Bermuda Hundred. These unit changes are reflected in the Order of Battle tables below.
Grant also pulled several heavy artillery batteries from the garrisons in the forts around Washington, D.C. and outfitted them with rifles. Although they bolstered brigade troop numbers, their inexperience in the field as infantry lead to proportionally higher casualties than other units in what would become one of the most costly campaigns of the war.

May 28-June 1, 1864 - Movement of Army of the James from Bermuda Hundred to Cold Harbor, Virginia
=== May 4 - Opening of the Campaign ===
 
Grant crossed the Rapidan River on May 4, 1864 with General Meade and the Army of the Potomac, hoping to force Lee into battle on open ground. He sought to either draw the Army of Northern Virginia from its Mine Run fortifications or flank it entirely. General Lee indeed took the southern forces from their entrenchments, but much earlier than Grant anticipated. Lee called in Ewell's Corps to march on the Orange Turnpike, A.P. Hill's Corps in parallel on the Orange Plank Road, and Longstreet's Corps from nearby GordonsvilleSalmon, p. 252; Eicher, pp. 662–64..
Lee decided to take yet another chance against a much larger Union force by ambushing the Army of the Potomac as it attempted to navigate through the thick brush and undergrowth known as the Wilderness. The terrain would not only mitigate the Union's superior numbers, but would also neutralize any major Union attempts at artillery bombardments. Troops on both sides were wary at the prospect of fighting near this field again, as the part of the battlefield overlapped the field from the slaughter at Chancellorsville the year before.
=== May 5-7 - The Wilderness ===
For further information, see the page for the Battle of the Wilderness
==== May 5 ====
 
 
Early in the morning on May 5, Warren began moving his 5th Corps troops towards the Orange Plank Road when Ewell's Confederate forces appeared on the Orange Court House Turnpike, approaching from the west. Meade halted the army's movement and directed Warren to attack if the Confederate force was small enough. Warren requested from Meade a delay in the action so that General Sedgewick's 6th Corps could be brought in to support an assault on the enemy position of unknown strength. Although the request was initially granted, Meade grew impatient with the delay and ordered Warren's 5th Corps to attack before Sedgewick's 6th Corps could arrive and extend the line to right. While Union troops delayed, the Confederates of Ewell's Corps erected earthworks on the western end of the clearing known as Saunders Field. 
The Union attack met heavy resistance all along the line of what would become the Wilderness battlefield: Brigadier General Joseph J Bartlett overran the Confederate position held by Brigadier General John M. Jones, killing him in the assault. To his right, Brigadier General Romeyn B. Ayres was forced to shelter his brigade in a gully to avoid enfilading fire from the larger-than-anticipated Confederate line. With Ayres unable to advance, Bartlett's right flank was now exposed to the enfilading fire and his brigade was forced back across the clearing.Rhea, Wilderness, pp. 101–103, 130, 140–56; Grimsley, pp. 35–36; Welcher, pp. 942–44; Eicher, pp. 664–65.
On Bartlett's left, Lysander Cutler's Iron Brigade slammed into a brigade of Alabamians under Brigadier General Cullen A. Battle. Battle's brigade was initially driven back, but counterattacked together with Brigadier General John B. Gordon's Brigade, shattering the Union line and forcing a rare retreat from the Iron Brigade. Two Union brigades under Colonel Roy Stone and Brigadier General James C. Rice assault positions of George P. Doles's Georgians and Junius Daniel's North Carolinians near the Higgerson Farm, both repelled with heavy casualties. Warren ordered an artillery battery into Saunders field to support the attacking Corps, which was captured by rebel troops as they drove attacking Union brigades back. During hand-to-hand combat at the guns, the field caught fire, burning alive pinned rebels and counterattacking federals alike.Rhea, Wilderness, pp. 138–39, 157–69, 176–81; Welcher, pp. 943–44; Eicher, pp. 665–66.
The lead element of Sedgwick's 6th Corps reached Warren's position by approximately 3:00pm, at which point the men of Warren's Corps were no longer fighting. Sedgwick attacked Ewell's Corps in the woods north of the Turnpike where the main fighting had occurred for the previous two hours. Both sides traded insignificant attacks for the next hour before breaking off the engagement and constructing earthworks for the next day's fight.
A separate engagement broke out south of the main fighting when Meade sent two Corps to intercept A.P. Hill's approach on Orange Plank Road. Meade sent Brigadier General George W. Getty's division from the 6th Corps to take and hold the intersection at Brock Road. Getty's Division arrived just before Hill's Corps and the two skirmished briefly before Hill pulled back from the intersection. Meade then sent Hancock's 2nd Corps to reinforce Getty's position and support an assault on Confederate Major General Henry Heth. Heth's troops pinned the first arrivals in place from a ridge, but as more divisions arrived, Hancock continuously fed them into the action. Eventually Lee was forced to commit a division of reserve troops under Major General Cadmus M. Wilcox, who held the line until the action ceased at nightfall.Eicher, pp. 664–67; Esposito, text to map 122; Grimsley, pp. 35, 39–41; Welcher, pp. 942, 945–47; Rhea, Wilderness, pp. 127–29, 133–36, 187–89, 191–229.
=== May 6 ===
On May 6, Hancock's II Corps attacked Hill at 5 a.m., overwhelming the Third Corps with the divisions of Wadsworth, Birney, and Mott; Getty and Gibbon were in support. Lee had assured Hill that Longstreet's Corps would arrive to reinforce Hill before dawn, but moving cross-country in the dark, they made slow progress and lost their way at times. Ewell's men on the Turnpike had attacked first, at 4:45 a.m., but continued to be pinned down by attacks from Sedgwick's and Warren's corps and could not be relied upon for assistance. Before a total collapse, however, reinforcements arrived at 6 a.m., Brig. Gen. John Gregg's 800-man Texas Brigade, the vanguard of Longstreet's column. General Lee, caught up in the excitement, began to move forward with the advancing brigade. As the Texans realized this, they halted, refusing to move forward unless Lee remained in the rear.[20]
Longstreet counterattacked with the divisions of Maj. Gen. Charles W. Field and Brig. Gen. Joseph B. Kershaw. The Union troops fell a few hundred yards back from the Widow Tapp farm. At 10 a.m., Longstreet's chief engineer reported that he had explored an unfinished railroad bed south of the Plank Road and that it offered easy access to the Union left flank. Longstreet's aide, Lt. Col. Moxley Sorrel, and the senior brigade commander, Brig. Gen. William Mahone, struck at 11 a.m. with four brigades. At the same time, Longstreet resumed his main attack, driving Hancock's men back to the Brock Road, but the momentum was lost when Longstreet was wounded by his own men, putting him out of action until October.[21]
At the Turnpike, inconclusive fighting continued for most of the day. Early in the morning, Brig. Gen. John B. Gordon scouted the Union line and recommended to his division commander, Jubal Early, that he conduct a flanking attack, but Early dismissed the venture as too risky and did not approve it until that evening. Gordon's attack made good progress against inexperienced New York troops, but eventually the darkness and the dense foliage took their toll as the Union flank received reinforcements and recovered.[22]
On the morning of May 7, Grant chose maneuver instead of further attacks. By moving south on the Brock Road, he hoped to reach the crossroads at Spotsylvania Court House, which would interpose his army between Lee and Richmond, forcing Lee to fight on ground more advantageous to the Union army. He ordered preparations for a night march on May 7 that would reach Spotsylvania, 10 mi (16 km) to the southeast, by the morning of May 8. Unfortunately for Grant, inadequate cavalry screening allowed Lee's army to reach the crossroads before sufficient Union troops arrived to contest it.[23]
