Regarding the United States in World War I, on 10, 12 and 13 April 1918, the lines being held by the troops of the 104th Infantry Regiment, of the 52d Infantry Brigade, of the 26th "Yankee" Division, in Bois Brule, near Apremont in the Ardennes, were heavily bombarded and attacked by the Germans. At first the Germans secured a foothold in some advanced trenches which were not strongly held but, thereafter, sturdy counterattacks by the 104th Infantry—at the point of the bayonet and in hand-to-hand combat—succeeded in driving the enemy out with serious losses, entirely re-establishing the American line.
