When America entered World War I in 1917 her armed forces were weak and unprepared but by the armistice in 1918 she had played a vital role in defeating the final German offensives and a leading part in the Allied advance which followed to bring about the German surrender. America's war production and her relations with her Allies provide the background to the exciting battles on land and in the air. All these aspects of the war are examined here and illustrated.
