On the evening of October 20, 1861, Union army commander George B. McClellan ordered Gen. Charles Stone to send a scouting party across the Potomac River to identify the positions of Confederate Col. Nathan Evans's troops near Leesburg. In the darkness the party's inexperienced leader, Capt. Chase Philbrick, mistook a line of trees for a line of tents, and reported that he had stumbled across an unguarded Confederate camp. Early the next day, Col. Charles Devens was sent across the river to attack the ca…READ MORE

Battle - Siege of Yorktown (1862) - York County, Virginia; Newport News, Virginia
Most of Gen. Joseph E. Johnston's army was not on the peninsula on April 4th when Maj. Gen. George B. McClellan departed Fortress Monroe on his Peninsula Campaign. The only force opposing the Yankee advance up the peninsula toward the Confederate capital at Richmond was Maj. Gen. John B. Magruder's small force of two divisions at Yorktown behind the Warwick River. Magruder's deceptive theatrics, conspicuously parading his men back and forth behind his defenses, convinced the Federals that his works were s…READ MORE

Gen. Joseph E. Johnston withdrew his army from the Virginia Peninsula toward the Confederate capital of Richmond as Maj. Gen. George B. McClellan's army pursued him. By the end of May, Johnston held a defensive position seven miles east of the city on the Richmond and York River Railroad.

Capturing the initiative from his Union foe, Johnston attempted to overwhelm two Federal corps isolated south of the river. The Confed…READ MORE

Battle - Gettysburg - Gettysburg, Pennsylvania
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.

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.

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.
