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

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

Confederate Maj. Gen. "Stonewall" Jackson hoped to cut off the Union retreat from Manassas the day after the Confederate victory at the second battle fought there. Jackson's wing of Lee's army made a wide, flanking march, screened by Maj. Gen. J.E.B. Stuart's cavalry, north and then east, to take the strategically important village of Germantown. There, Maj. Gen. John Pope's only two retreat routes to Washington - the Warrenton Pike and the Little River Turnpike - converged. On September 1st, beyond Chanti…READ MORE

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 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.
