I visited Gettysburg, Pennsylvania and it’s just very sad to see so many thousands upon thousands of people died on a beautiful hilly battlefield in breathtaking scenery.
How could Americans want to KILL Americans?????
And why did Confederates take the war into Pennsylvania, which was a “Free state?”
This isn’t even about seceding from the union, they took the war into Union territory 
so much bloodshed for NOTHING???? When you visit the battle field it all comes to life.
