In May and June 1918 the newly arrived American Expeditionary Force fought two actions that helped defeat the last German offensive of World War I. At Chateau Thierry a combined French and American force stopped the Germans from crossing the Marne River. Building on this success the US 2nd Division stopped the German advance on Paris and were given the task of recapturing Belleau Wood. First-hand accounts, photographs, and detailed maps dramatically bring to life these key battles, America’s baptism of fire in World War I.
