Explanation:

The Battle of Gettysburg (July 1-3 1863, southwest of Harrisburg , Pennsylvania), a major victory for the North and a crushing defeat for the South, was the turning point in the Civil War. Gen. Robert E. Lee´s intentions to enter northern soil were to give relief to Virginia, devastated by the war; take the fight to enemy territory in order to force Abraham Lincoln´s administration to negotiate peace. Nevertheless, his plan failed and backfired. In an intense fight for three days, the Union Army held its line and repelled Confederate attacks. The victory boosted the North´s morale and disillusioned Southerners. The South lost many men, including many top officers - generals and colonels - , and it never was able to attack the North and from then on, it fought the war on the defensive.
