called a lunette. they did have logs in the back to try to close it in to support it. while the quote, battle of ft. stevens was going on july 11th to 12th, abraham lincoln, not that far away, came out to the fort, and he actually got up on the parapet to look out to see where the troops were. and there were actually some sharpshooters who took shots at him. they did not hit him. one of the -- of the story, is and i've often wondered if this is true or not, oliver wendell holmes who became famous later, was said to have said get down, you fool, meaning get down before you get shot. i doubt that that happened, but there are people that said that that is what oliver wendell holmes said, but this is the only time that a president of the united states has actually been under fire while president of the united states, so abraham lincoln here, standing on the parapet looking out to see where the enemy troops actually were. >> you can watch this and other american artifacts programs site, c-span.org/history. and watch american artifacts every sunday at 8:00 a.m., 7:00 p.m. ea
