Gettysburg National Military Park
If there is a home for the soul of America, it is almost certainly on the battlefields of Gettysburg. Here, in July 1863, the Union and Confederate armies clashed in the bloodiest battle ever fought on American soil. In three days of fighting, more than 51,000 men were killed, wounded, captured or went missing (nearly a third of all those who fought here); when all was said and done, the once unstoppable Confederate army was forced to retreat.
