First, the Union transformed the purpose of the struggle from restoring the Union to ending slavery. While Lincoln’s Emancipation Proclamation actually succeeded in freeing few of the enslaved, it made freedom for African Americans a cause of the Union. Second, the tide increasingly turned against the Confederacy. The success of the Vicksburg Campaign had given the Union control of the Mississippi River, and Lee’s defeat at Gettysburg had ended the attempted Confederate invasion of the North.
