Following the Confederate withdrawal from their Yorktown position, Maj. Gen. George B. McClellan was not prepared to mount an immediate pursuit with his entire force from the siege lines he had occupied for nearly a month. Initially, he was able to send forward only a portion of his army, led by the Third Corps of Samuel P. Heitzelman, to follow Gen. Joseph E. Johnston's Confederates. Heitzelman's divisions, led by Brig. Gens. Joseph Hooker and Phil Kearny, made contact with Johnston's army four miles sout…READ MORE

Wilderness

The first battle between Lt. Gen. Ulysses S. Grant and Gen. Robert E. Lee erupted late in the morning of May 5, 1864, as Maj. Gen. Gouverneur K. Warren's Union V Corps attacked Lt. Gen. Richard S. Ewell's Second Corps on the Orange Turnpike southwest of the old Chancellorsville battlefield. Although Federal infantry managed to break through at several points, the Confederate line held. Fighting shifted to the south as Lt. Gen. A.P. Hill's Third Corps engaged Maj. Gen. Winfield S. Hancock's II Corps and ele…READ MORE

Spotsylvania Court House

Following the Battle of the Wilderness, Lieut. Gen. Ulysses S. Grant marched the Union army south with the hope of capturing Spotsylvania Court House and preventing Robert E. Lee's army from retreating further. Lee's Confederates, however, managed to get ahead of the Federals and block the road. Fighting began on May 8th, when the Union Fifth Corps under Maj. Gen. Gouverneur K. Warren and the Sixth Corps under Maj. Gen. John Sedgwick engaged Confederate Maj. Gen. Richard Anderson's First Corps at Laurel Hi…READ MORE

Following the stalemate at Spotsylvania Court House, Grant was determined to continue his offensive against Lee's Army of Northern Virginia. After a failed attempt to bait Lee out of his earthworks, he found the Confederates entrenched on the south side of the North Anna River, where Lee's "inverted V" defenses forced Grant to divide his army into three parts in order to attack. On May 23rd, one of Maj. Gen. A.P. Hill's divisions assaulted the isolated Fifth Corps on the Union right which had crossed the r…READ MORE

Cold Harbor

After two days of inconclusive fighting along Totopotomoy Creek northeast of Richmond, Lt. Gen. Ulysses S. Grant and Gen. Robert E. Lee turned their sights on the crossroads of Cold Harbor. Roads emanating through this critical junction led to Richmond as well as supply and reinforcement sources for the Union army. On May 31, 1864, Maj. Gen. Philip Sheridan's cavalry captured Cold Harbor. The next day, Sheridan held the crossroads against a Confederate attack. With reinforcements from both armies arriving…READ MORE

In June of 1864, hoping to draw attention away from Lieut. Gen. Ulysses S. Grant's movement south, destroy supply lines, and join up with Brig. Gen. David Hunter in Charlottesville, Union cavalry commander Maj. Gen. Philip Sheridan embarked on a cavalry raid. Near Trevilian Station, Virginia, he clashed with Confederate cavalry under Maj. Gens. Wade Hampton and Fitzhugh Lee. On June 11th, while Hampton's men struggled against Union forces on one road, Lee's men advancing on a parallel road fell back, allow…READ MORE

First Deep Bottom

Two weeks after Union forces arrived to invest the Confederate defenders of Petersburg, the battle lines of both sides settled into a stalemate. Since Cold Harbor, Lieut. Gen. Ulysses S. Grant was reluctant to mount a large frontal attack against well-entrenched Confederates. By late June, Grant's lines covered most of the eastern approaches to Petersburg, but neither side seemed ready to risk an offensive move. Determined to break the stalemate, Grant agreed to plans to blow up part of the Confederate def…READ MORE

As he had done in late July during the Battle of the Crater, Lieut. Gen. Ulysses S. Grant called upon Maj. Gen. Winfield S. Hancock and his Second Corps to attack Gen. Robert E. Lee's forces around Richmond to exploit suspected weaknesses in Lee's lines. In early August, Grant had detached the Sixth Corps from the Union lines around Richmond and Petersburg and sent them to the Shenandoah Valley under Maj. Gen. Phil Sheridan. Sheridan's new army there was to counter Gen. Jubal Early, then operating in the v…READ MORE

Second Ream's Station

As the Union siege of Petersburg began to take hold, Lieut. Gen. Ulysses S. Grant looked for ways to sever the railroads supplying the city and Gen. Robert E. Lee's army. One of these critical routes was the Weldon Railroad, which led south to the Confederacy's only remaining major port at Wilmington, North Carolina. On August 24th, the Army of the Potomac Second Corps moved south along the railroad, tearing up track, and screened by Brig. Gen. David McMurtrie Gregg's cavalry division. To stop Hancock, Lee…READ MORE

By late March 1865, the battle lines surrounding Petersburg had extended west into Dinwiddie County. Lieut. Gen. Ulysses S. Grant knew his larger army could eventually stretch Gen. Robert E. Lee's Confederates to the breaking point. On March 30th, Lee shifted reinforcements to meet a Federal movement to turn his right flank along the line, placing Maj. Gen. W.H. Fitzhugh Lee's cavalry divisions at Five Forks and transferring Maj. Gen. George Pickett's division from the Bermuda Hundred front to the extreme…READ MORE

With the Confederate defeat at Five Forks on April 1st, Lieut. Gen. Ulysses S. Grant and Maj. Gen. George Meade ordered a general assault against the Petersburg lines by the Second, Ninth, Sixth and Twenty-Fourth Corps to take place April 2nd. In the pre-dawn darkness, the Union infantry gained a successful breakthrough where Maj. Gen. Horatio G. Wright's advancing Sixth Corps met the Confederate lines held by Maj. Gen. A. P. Hill near the Boydton Plank Road. Hill was killed trying to reach his troops in t…READ MORE

Five days after Robert E. Lee's men retreated from the trenches of Petersburg, cavalry under Maj. Gen. Phil Sheridan effectively cut off three separate corps of Lee's army near Sailor's Creek, a tributary of the Appomattox River, while the Union Second and Sixth Corps approached from the east. On April 6th, two brigades of Andrew H. Humphrey's Second Corps overwhelmed two brigades of Maj. Gen. John B. Gordon's division as the Confederates struggled to move their supply and artillery trains across the creek…READ MORE
