Abraham Lincoln
Battle of Chancellorsville
Spotsylvania County, Virginia, U.S.
Hooker was routed by Lee at the Battle of Chancellorsville in May, then resigned and was replaced by George Meade. Meade followed Lee north into Pennsylvania and beat him in the Gettysburg Campaign, but then failed to follow up despite Lincoln's demands. At the same time, Grant captured Vicksburg and gained control of the Mississippi River, splitting the far western rebel states.
