Lead: One hundred and fifty years ago the Republic was facing its greatest crisis. This continuing series examines the American Civil War. It is "A House Divided."

Intro.: A Moment in Time with Dan Roberts.

Content: Nothing comparable had ever happened on the North American continent. Back in 1861, all but a few thought it was supposed to be over with a few shots fired, yet there on a creek side in western Tennessee this springtime 1862 encounter issued forth a cascade of blood unequalled in the American experience. Over two days, the war in the West was largely decided if not completed. Shiloh or Pittsburg Landing would not yield the bloodiest day, that would come later in the fall at Antietam, or the most casualties, that would await the three days at Gettysburg a year away, but it was enough to cure any but the most foolish of lingering romantic notions of war. It was a brutal slog, and in the end yielded 20,000 dead and wounded split evenly between the two sides.
