Why was the Battle of Gettysburg a turning point in the Civil War?

At Gettysburg, Union forces defeated Robert E. Lee’s Confederate army and ended its invasion of the North. The Confederacy fought on for nearly two more years, so this was not the Union’s final victory, but Lee’s army was weakened and did not launch another major invasion of the North. Therefore, the correct choice is “The battle weakened Lee and stopped his invasion.”
