"Shiloh had the same number of casualties as Waterloo, and yet when it was fought there were another twenty Waterloos to follow; and Grant shortly before Shiloh said 'I consider this war practically over and they're ready to give up', and the day after Shiloh he said 'I saw this was going to have to be a war of conquest if they were going to win'. Shiloh did that, and it sobered the nation up something awful with the realization that they had a very bloody affair on their hands."
