5:30am - 17 Sept 1862 - Sharpesburg, Maryland - the Federal advance is met by Stonewall Jackson's Confederate artillary.
One Confederate described the cannons at Sharpsburg as "artillery hell."
The roll of thunder breaks the pre-dawn silence.
Round after round is poured into the Federal lines.
The artillery fire lit up the cornfield.
Federal artillery pounded Jackson's men.
Colonel Marcellus Douglass' Georgia brigade forms up. They wait for the order to advance.
Men from Jackson's Corps move into the Cornfield. Soon they were locked in a deadly struggle with the Federals; "They stood and shot one another 'till the lines melted away." Issac Hall, 97th New York.
The survivors of Hood's attack, down to their last cartridges, withdrew from the Cornfield. When asked where was his division, Hood replied, "Dead on the field."
Men from the 1st Texas await their turn in the Cornfield. In less than 20 minutes 186 of the 226 men that went into the Cornfield lay dead or wounded.
When will it be their turn?
The sun rises; the battlefield is hidden by morning mist and black smoke.
Five regiments of the Louisiana Brigrade - the Tigers - enter the Cornfield. To counter the attack, the Federals opened fire with a battery of cannons at point blank range - the Tigers went down in droves.
The cannons fall silent as the infantry make their way to the front.
They were just boys, but they too were part of America's deadliest day - 17 Sept 1862.
