Concept note-1: -His hope was to catch the Union army off guard and also to move the war away from the impoverished fields of Virginia and other parts of the South and take advantage of the fertile fields and plentiful livestock in Maryland and Pennsylvania.
Concept note-2: -Even in his role as general, Lee was playing politics. He understood that a victory in Pennsylvania would encourage the Northern peace movement, damage Republican interests, increase the possibility of foreign recognition, and perhaps even lead to a negotiated peace and Confederate independence.
Concept note-3: -Although he felt slavery in the abstract was a bad thing, he blamed the national conflict on abolitionists, and accepted the pro-slavery policies of the Confederacy. He chose to fight to defend his homeland.
Concept note-4: -His hopes of a victorious invasion of the North dashed, Lee waited for a Union counterattack on July 4, but it never came. That night, in heavy rain, the Confederate general withdrew his decimated army toward Virginia. The Union had won the Battle of Gettysburg.
