Concept note-1: -The Battle of Antietam remains the bloodiest single day in American history. The battle left 23, 000 men killed or wounded in the fields, woods and dirt roads, and it changed the course of the Civil War.

Concept note-2: -Why was Antietam so deadly? Advanced technology, unwise tactics, and terrible decision-making.
