Before the mid-1916 National Defense Act the US Army had a few tens of thousands of men, but by November 1918 there were nearly a million and a half American combat troops in France. General Pershing's American Expeditionary Force arrived in 1917 short of weapons, equipment, and experience of modern warfare; but it proved itself in the fighting on the Argonne, and played a major part in stopping Germany's last offensive in spring 1918, and in the final advance through the Hindenburg Line. This book details the organisation, uniforms, equipment and campaigns of the US Army in World War I.
