Gettysburg

In the summer of 1863, Confederate Gen. Robert E. Lee launched his second invasion of the Northern states. Lee sought to capitalize on recent Confederate victories and defeat the Union army on Northern soil, which he hoped would force the Lincoln administration to negotiate for peace. Lee also sought to take the war out of the ravaged Virginia farmland and gather supplies for his Army of Northern Virginia. Using the Shenandoah Valley as cover for his army, Lee was pursued first by Union Maj. Gen. Joseph Ho…READ MORE

After the inconclusive Bristoe Campaign in the fall of 1863, Maj. Gen. George G. Meade planned one more offensive against Gen. Robert E. Lee in northern Virginia before winter weather ended military operations. In late November, Meade attempted to steal a march southeast from Culpeper Courthouse, turn south through the Wilderness and strike the right flank of the Confederate army south of the Rapidan River. On November 27th, Maj. Gen. Jubal A. Early, in command of Ewell's Corps, marched east on the Orange…READ MORE

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

Second Petersburg

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
