Nearly a century has passed since the truce was signed on November 11, 1918. Of all the soldiers who passed through this hell on earth, photographs, letters, stories and old school uniforms remained in the attics.

Thanks to a collection of more than ten thousand documents, the author allows us to follow up on these young people who have previously invisible images. All these faces, sometimes smiling, sometimes serious, have a story to tell.

Many collectors have allowed us to reach their most precious things, the result of their constant search that helps to save these things that have gone through four years of oblivion and destruction. Finally, in the Internet age, many links allow you to track the history of your ancestors and their cohorts.

In 1917, the US military joined the war, reinforcing the morale of the present soldiers and giving impetus to the attack. Initially a small, well-equipped force of 135,000 men, the US military quickly turned into an exploratory force, which at the end of the conflict was two million men.

The subject of this short book is a non-exhaustive study of American soldier equipment and its commitment to American reconnaissance forces in France in 1817-1917.
