Continuing their rapid northward advance the Second Corps arrived at Monocacy Junction in Maryland, where they received news of a change in command of the Union Army. General George Meade, leader of the Fifth Corps, replaced General Joseph Hooker as commander of the Army of the Potomac. As this news reached the Second Corps Confederate Cavalry General James Ewell Brown (J.E.B.) Stuart continued his raid in the rear of the Union Army, capturing a large supply train and causing panic in Washington, D.C.1
