This episode examines the Battle of Chancellorsville from 30 April to 6 May 1863, Robert E. Lee's most audacious victory of the American Civil War and a masterclass in aggressive manoeuvre against a superior force.

General Joseph Hooker's 130,000 strong Army of the Potomac, crossed the Rappahannock and Rapidan Rivers and positioned itself on Lee's flank at Chancellorsville in what Hooker described as the finest movement in military history. Lee, with fewer than 60,000 men, responded by dividing his Army to face the Union force to his front at Fredericksburg, and on his left flank around the Chancellor House crossroads. Lee then divided his army a second time — sending Lieutenant General Thomas "Stonewall" Jackson on a 12-mile flank march through the Wilderness to strike Hooker's exposed right flank held by the Eleventh Corps under General Oliver Howard.

At 1715 on 2 May 1863 Jackson's 28,000 men emerged from the tree line and rolled up the Union right flank in one of the most devastating surprise attacks in American military history. The Eleventh Corps collapsed. The attack drove the Union army back toward the river. The Confederate seizure of Hazel Grove, the commanding high ground, gave Confederate artillery the platform to dominate the battlefield the following day.

The victory cost Lee more than he could afford. Returning from a night reconnaissance on 2 May, Jackson was accidentally shot by his own men, North Carolina troops of the 18th Infantry Regiment who mistook his party for Union cavalry. His left arm was amputated. He died of pneumonia eight days later on 10 May 1863. Lee's response, "I have lost my right arm", became one of the most quoted statements of the entire war.

Drawing on the official records of both armies, the after-action reports of Jackson's Corps commanders, personal exploration of the Chancellorsville battlefield and the site where Jackson was wounded on the Plank Road, and GIS terrain analysis of the flank march route and the Hazel Grove position, the episode examines Hooker's plan and its failure of nerve, the mechanics of Jackson's flank march, the collapse of the Eleventh Corps, and why Chancellorsville is simultaneously Lee's greatest tactical triumph and the beginning of the Confederacy's irreversible decline.

The Chancellorsville battlefield is preserved as part of the Fredericksburg and Spotsylvania National Military Park. The site where Jackson was wounded on the Orange Plank Road is marked. The Chancellorsville visitor centre holds one of the finest collections of Civil War campaign maps in existence.
