How did the Confederate Army win in the Battle of Gettysburg?
The Confederacy did not win the battle of Gettysburg. The Union army was getting close to losing, but some how they defeated the Confederacy in The Battle of Gettysburg. It was not a decisive victory. No one surrendered and Lee escaped to the South with much of his force intact. Because the Army of Northern Virginia escaped, President Lincoln brought Grant in from the West. That was change in the power struggle.
