He was a Hero.

October 8th, 1918 - Sergeant Alvin C. York:

"It was here that Alvin distinguished himself in combat. On October 8, 1918, Corporal Alvin C. York and sixteen other soldiers under the command of Sergeant Bernard Early were dispatched before sunrise to take command of the Decauville railroad behind Hill 223 in the Chatel-Chehery sector of the Meuse-Argonne sector. The seventeen men, due to a misreading of their map (which was in French not English) mistakenly wound up behind enemy lines. A brief fire fight ensued which resulted in the confusion and the unexpected surrender of a superior German force to the seventeen soldiers. Once the Germans realized that the American contingent was limited, machine gunners on the hill overlooking the scene turned the gun away from the front and toward their own troops. After ordering the German soldiers to lie down, the machine gun opened fire resulting in the deaths of nine Americans, including York's best friend in the outfit, Murray Savage. Sergeant Early received seventeen bullet wounds and turned the command over to corporals Harry Parsons and William Cutting, who ordered York to silence the machine gun. York was successful and when all was said and done, nine men had captured 132 prisoners."
