Alvin York (1887-1964) was one of the most famous Americans of the Great War following his fighting exploits accomplished in the woods on the Châtel hills. On 8th October 1918, following violent attacks from machine guns, Corporal York (328th infantry - 82nd division) took command of a small group of 7 men and launched an attack on German positions. After repelling a bayonet attack, they stormed the enemy machinegun nests.
132 German soldiers were taken prisoner, including 4 officers. York was to immediately be appointed Sergeant. According to Marshal Foch, commander of the Allied Armies, it was, "The greatest feat carried out by a simple soldier fighting for any of the armies in Europe." His feat earned him the Congressional Medal of Honor and fame in the United States.
Hollywood devotes a film to him directed by Howard Hawks in 1941 with Gary Cooper in the role of Sergeant York.
As for the present, a 3-km long historical tour in the forest can help you discover where the fighting took place.
