During May and June 1864, near the war's closing phase, a string of engagements swept across Virginia under names that would later become interchangeable: the Overland Campaign, Grant's Overland Campaign, the Virginia Campaign, and the Wilderness Campaign. Ulysses S. Grant, holding the rank of Lt. Gen. and serving as general-in-chief over all Union forces, oversaw operations carried out by Meade's Army of the Potomac alongside additional units, all pitted against Lee's Army of Northern Virginia. Grant's forces absorbed heavy casualties throughout, yet the campaign ultimately counted as a strategic win for the Union side. Lee's army bled at a rate disproportionate to Grant's own losses, and within roughly eight weeks it found itself pinned down in a siege centered on Richmond and Petersburg.

Grant pushed his troops across the Rapidan River on May 4, 1864, aiming to slip between Lee and Richmond before the Confederates could react, hoping this would force a decisive open engagement. Lee, however, struck first, catching the numerically superior Union force off guard in the Wilderness (fought May 5 through 7), a clash that produced heavy losses for both armies. Where earlier Union commanders in the east would have pulled back after such a bloody check, Grant instead pressed onward, shifting his army southeast in a renewed effort to get between Lee and the Confederate capital. Lee managed to reposition in time to block this move. The two armies then collided at Spotsylvania Court House between May 8 and 21, where Grant hurled repeated assaults at portions of the Confederate line in search of a decisive break, but the fighting only piled up further casualties without producing the hoped-for breakthrough.

Grant shifted his army once more, and the two commanders met along the North Anna River from May 23 to 26. Lee arranged his defenses cleverly there, splitting the Union force to strike at its divided pieces, though historians still argue over how well the scheme actually worked. The campaign's last major clash came at Cold Harbor, spanning May 31 to June 12. Believing Lee's army had been worn down, Grant staked everything on a large scale assault against heavily fortified positions, a gamble that cost the Union side casualties far exceeding those of the Confederates. Turning to maneuver one final time, Grant caught Lee off guard by quietly moving his army across the James River, putting Petersburg within reach and, with it, the possibility of dooming the Confederate seat of government at Richmond. What followed was the siege of Petersburg, stretching from June 1864 to April 1865, which eventually forced Lee's army to surrender that April and brought the Civil War to its conclusion.

Alongside the main fighting, Maj. Gen. Philip Sheridan led Union cavalry on two extended raids during the campaign. One thrust toward Richmond led to the mortal wounding of Confederate cavalry leader Maj. Gen. J.E.B. Stuart at Yellow Tavern on May 11. A second raid, aimed at wrecking the Virginia Central Railroad to the west, was checked by Maj. Gen. Wade Hampton in the Battle of Trevilian Station, fought June 11 and 12, which stands as the largest cavalry engagement of the entire war.

Opposing forces

Numbers alone did not tell the whole story for Grant, who faced real difficulties in keeping his army whole and effective. The I Corps and III Corps, having suffered a brutal mauling at Gettysburg the year before, no longer existed as such; their remaining men had been folded into other corps, a shuffling that eroded both cohesion and morale among the units affected. Grant's position as the attacker deep in hostile territory also created a persistent burden: he needed to protect his supply bases along with the lines connecting them to his army in the field. This concern drove much of his strategy, explaining his repeated maneuvers around Lee's right flank throughout the campaign and his preference for supply routes by water rather than depending on interior Virginia railroads like the Orange and Alexandria. Compounding matters, a large portion of his troops were nearing the end of three-year enlistment terms, leaving them understandably hesitant to throw themselves into perilous attacks. Grant addressed this shortage of willing infantry by pulling soldiers from the heavy artillery units stationed around Washington, D.C., and folding them into infantry regiments instead.

Spotsylvania Court House (May 8-21)

At first light on May 8, Fitzhugh Lee's horsemen took up a defensive position atop a low rise they called "Laurel Hill." Anderson's reinforcements got there right as Warren's soldiers halted a hundred yards to the north. Believing he faced nothing but cavalry, Warren pushed forward with an immediate assault. The V Corps divisions charged repeatedly but were thrown back each time, suffering heavy losses. That afternoon Sedgwick's VI Corps reached the vicinity of Laurel Hill and stretched Warren's line farther east. As evening approached around 7 p.m., the two corps launched a joint attack together, only to be driven off by intense fire. When they tried swinging around the right side of Anderson's line, they discovered to their surprise that Ewell's Second Corps divisions had already moved into that area and beat them back once more.

Tension had been building between Meade and Sheridan over the cavalry's conduct during the campaign, and the setbacks of May 7 and 8 finally ignited Meade's famous anger. Sheridan declared to Meade that given the chance, he could defeat Stuart outright. When Meade relayed this exchange to Grant, Grant responded simply that Sheridan usually knew what he was talking about and should go ahead and prove it. Bowing to Grant's wishes, Meade instructed Sheridan to move against the enemy's mounted forces. The next day, Sheridan rode out with his full force of ten thousand troopers. They clashed with Stuart's men at Yellow Tavern on May 11, fatally wounding the Confederate cavalry commander, pushed to the edge of Richmond, paused to resupply close to the James River, and did not rejoin Grant's army until May 24. This left Grant and Meade without any cavalry support during some of the most decisive days of the coming fight.

During the night between May 8 and 9, Confederate forces built earthworks stretching over four miles, centered on a vulnerable bulge called the "Mule Shoe" that jutted more than a mile ahead of the main line. Around 9 a.m., Major General John Sedgwick, while checking on his VI Corps position, was struck fatally in the head by a Confederate marksman's shot, killing him on the spot. Major General Horatio G. Wright took his place in command.

Grant directed Hancock to push across the Po River and strike the Confederate left, forcing it back toward where Burnside stood near the Ni River, while the remaining Union troops in the center looked for any chance to press forward as well. Hancock's II Corps made it across the Po but put off the actual assault until the following morning, a delay that would prove disastrous for Grant's overall design. That night Lee shifted two of Jubal Early's divisions from Spotsylvania Court House to confront Hancock directly. Come the morning of May 10, Grant instructed Hancock to pull back north across the Po, leaving behind only one division to keep the Confederates occupied there, while ordering a general assault across the whole Confederate front for 5 p.m. At 2 p.m., Early struck the isolated division, which managed to retreat over the Po intact, burning the bridges as it went to prevent pursuit.

While this action unfolded in the Po sector, Warren asked Meade for permission to strike Laurel Hill at 4 p.m., separate from Grant's larger coordinated plan. Once again the defenders at Laurel Hill drove the attackers back with serious losses. Because of this, Grant had to push back his planned 5 p.m. assault until Warren's men could regroup. Unaware of this postponement, Brigadier General Gershom Mott of the II Corps sent his division forward at the original 5 p.m. hour toward the point of the Mule Shoe. The moment his troops entered open ground, Confederate cannon fire tore through their ranks and forced a retreat. Roughly an hour later, Colonel Emory Upton led twelve specially chosen regiments, numbering about five thousand men arranged in four lines, against a weak spot spotted on the western face of the Mule Shoe. His men were ordered to dash across the field without stopping to fire, hoping to reach the enemy works before more than a shot or two could be loosed at them. The tactic succeeded at first, but Lee and Ewell moved swiftly to organize a strong counterattack using brigades drawn from every part of the salient. With no Union troops arriving to back him up, Upton was forced to pull his men back out of the captured works.

Even after the setb

Yellow Tavern (May 11)

During the campaign's opening stretch, through the Wilderness and the march toward Spotsylvania Court House, Meade had mostly limited Sheridan's Cavalry Corps to screening the army and gathering intelligence. Sheridan, however, believed his mounted force could accomplish far more if unleashed as an independent strike unit, capable of driving deep raids against the enemy's rear. He raised this idea with Meade on May 8, arguing that given full freedom of movement, he could bring Stuart to defeat. Grant found the proposal compelling and persuaded Meade to grant Sheridan's wish.

The following day, more than ten thousand of Sheridan's horsemen set out southeastward, bringing thirty two guns along as they swung around behind Lee's army. Stretching more than thirteen miles at points, this long column arrived at Beaver Dam Station by nightfall, striking a key Confederate supply depot there. The raiders wrecked a large number of railcars along with six locomotives belonging to the Virginia Central Railroad, cut telegraph lines, and freed close to four hundred Union prisoners who had been taken during the Wilderness fighting.

Seeking to block the Federal horsemen from reaching Richmond, Stuart maneuvered his 4,500 troopers into their path. Around midday on May 11, the two sides clashed near Yellow Tavern, a deserted roadside inn some six miles north of the Confederate capital. The Federals held a heavy edge in numbers, fielding three divisions against two Confederate brigades, and their advantage extended to weaponry as well, since every trooper carried a rapid firing Spencer carbine. Even so, the Confederate cavalrymen held their ground stubbornly along a low ridge overlooking the Richmond road, sustaining the fight for better than three hours. When Union riders pressed toward the crest, a charge by the 1st Virginia Cavalry drove them back down the hill, with Stuart on horseback calling out encouragement to his men. It was in the midst of this action, as troopers of the 5th Michigan Cavalry fell back past his position, that Stuart was struck by a bullet; he succumbed to the wound in Richmond the next day. Combat continued for roughly another hour following his wounding, with Maj. Gen. Fitzhugh Lee stepping in to lead in his place.

Aftermath

Grant's decision to cross the James River marked a departure from his initial plan of pushing straight toward Richmond, setting in motion the siege of Petersburg instead. Once Lee discovered this move, the very outcome he dreaded most was taking shape: a defensive siege to protect the Confederate capital. Petersburg itself, home to some 18,000 residents and a thriving economy, functioned as Richmond's supply hub. Its position just south of the capital, its location along the Appomattox River offering water passage to the James, and its status as a hub where five separate railroads converged all made it indispensable. Because the city served as the primary depot and rail junction for the whole region, including Richmond, its capture by Union troops would leave Lee with no way to keep defending the capital. This marked a shift away from the approach used throughout the Overland Campaign, where the central aim had been to meet and beat Lee's army head on in open combat. Grant now fixed his sights on a location chosen for both geography and politics, confident that his greater resources would let him trap Lee there, pin him in place, and either force surrender through starvation or provoke him into a final showdown.
