What was the bloodiest battle of the world war 1 for american troops?
The Meuse-Argonne Offensive. Americans took over this section of trenches from the French, who had not attacked in this area since 1915. The French considered that these German positions were too strong to be carried by an attack. The German defenses were overgrown and very difficult to spot, situated along the high ground. US forces had to attack in the Argonne Forest, uphill most of the time, at these naturally concealed positions. The attack opened on September 26, 1918 and was still going on when the war ended on November 11.
