Stonewall Jackson

From the collection of Donald Olson

Confederate Lieutenant General Thomas J. "Stonewall" Jackson was shot by friendly fire during the Battle of Chancellorsville in 1863. Now astronomers say they know why his own troops couldn't recognize him: The full moon was shining right into their faces, putting the Confederate commander in stark silhouette. [Full story]

Union Major General Daniel E. Sickles' Midnight Attack

From the collection of Donald Olson

By the light of a bright full moon, Union Major General Daniel E. Sickles's corps launched a midnight attack on May 2-3, 1863. According to a New York Times war correspondent, “This night attack was the most grand and terrific thing of the war. The moon shone bright, and an enemy could be seen at good musket range.” This woodcut appeared in the Official and Illustrated War Record (1898).

The Stonewall Jackson Monument

From the collection of Donald Olson

A group in a passing carriage on the Plank Road views the Stonewall Jackson monument in this chromolithograph, titled “The Place Where Stonewall Jackson Fell, Mortally Wounded” and published in 1890 by John House. Modern visitors will find the monument still standing just north of Route 3, adjacent to the Chancellorsville Battlefield Visitor Center. The monument was erected in 1888 near the spot where Jackson’s wounds were initially tended. Visitors can follow a short trail east of the visitor center to the actual site of the fatal volley. A text panel on the monument explains the origin of the general’s nickname by reproducing the famous quote attributed to Brigadier General Barnard Bee describing the fighting at First Manassas: “There is Jackson standing like a stone wall.”
