Of course, no one knew it at time, but the Germans launched their last offensive on the western front on July 15, 1918, when they attacked before dawn across a 65-mile front. U.S. positions west of Chateau Thierry were part of the target.
On the 16th, U.S. forces staged a counterattack against a German salient, but the Associated Press reports were vague about the location and the size of the attack.
An early casualty of the offensive was Lt. Quentin Roosevelt, youngest son of former President Teddy Roosevelt, who was killed in an aerial combat near Chateau Thierry. The initial AP report simply said that he was returning from a patrol when he was attacked by seven German planes.
