There were over 50,000 casualties during that time. There were over 8,000 left dead on the field and needed to be buried quickly which is why they were popping up every time a plow went in the ground, or a clearing for a new road, etc. Thousands more died of their wounds. The place was a horror show not only during the battle but for months after in the field hospitals. Just about every house, every church, hotel, and barn were packed with wounded and dying in that sleepy town. Modern day Gettysburg is still about the same size as there are strict limitations on growth there. Truly folks... if you can... go see it.
