The real turning point of the Civil War was Grant's capture of Vicksburg, closing the Mississippi to Confederate control. It completed Phase Two of the Anaconda Plan, made Grant the prime candidate for overall Union command, and set the stage for Sherman's March to the Sea.
Most historians and scholars believe the turning point of the American Civil War was the Battle of Gettysburg fought in July 1863.
