This is the focal point of the Military Cemetery at Shiloh National Battlefield, this morning.
3500 Americans died here ours of fighting in April, 1862. 18,000 were wounded.
In terms understandable, this is a greater fraction of the US population, at the time, than the percentage of Americans lost during the ENTIRE Vietnam conflict. Had there been the communication we have today, this would have been a much shorter war...
