In early July 1863, the Civil War began to turn in the Union's favor following the Union Army under General Ulysses S. Grant successfully splitting the Confederacy in two by capturing Vicksburg in the west, denying it any further movement along or across the Mississippi River and preventing supplies from Texas and Arkansas that might sustain the war effort from passing east, almost simultaneous with victory in the Battle of Gettysburg, where Union Army general George Meade halted Confederate Army general Robert E. Lee's invasion of the North.
