After his success at Second Manassas, Gen. Robert E. Lee led the Army of Northern Virginia north across the Potomac River on an invasion of Maryland in September of 1862. Lee divided his army, sending a portion of it into western Maryland while Lieut. Gen. Stonewall Jackson's wing attempted to capture the Federal garrison at Harper's Ferry. The bold plan was jeopardized on September 13th when a mislaid copy of Lee's orders revealing the Confederates' plans was given to Union commander Maj. Gen. George B. M…READ MORE

In mid-May, 1863, after six months of unsuccessful attempts, Maj. Gen. Ulysses S. Grant's Army of the Tennessee finally converged on Vicksburg, defended by a Confederate army under Lt. Gen. John C. Pemberton. Capture of the Mississippi River town was critical to Union control of the strategic river. Vicksburg was located on a high river bluff defended with artillery, and Pemberton's men had constructed a series of fortifications in an 8-mile arc surrounding the city on the landward side.

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.

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

As the Overland Campaign concluded, the strategic goals of Lieut. Gen. Ulysses S. Grant shifted from the defeat of Robert E. Lee's army in the field to eliminating the supply and communication routes to the Confederate capital at Richmond. The city of Petersburg, 24 miles south of Richmond, was the junction point of five railroads that supplied the entire upper James River region. Grant knew Petersburg was the key to the capture of Richmond and that Lee would be forced to defend it. Marching south from Co…READ MORE

Two weeks after Union forces arrived to invest the Confederate defenders of Petersburg, the battle lines of both sides had settled into a stalemate. Since Cold Harbor, Lieut. Gen. Ulysses S. Grant was reluctant to mount a 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. Part of the Union line was held by Maj. Gen. Ambrose E. Burnside's Ninth Corps. Some of Burnside'…READ MORE
