This is a history of World War I compiled of memoirs written by some of the common soldiers and an explanation of what they did in various positions. From the intro:
“IN ASSEMBLING the stories contained in this book we have endeavored to put in realistic and readable form some of the actual, and authentic, experiences of soldiers and officers of the Allied Forces, who have returned to their homes after nobly sacrificing themselves in the service of their respective countries. It has been our endeavor to give to these stories as much of the personality of "The Boys," who have told us their experiences, as possible, by using their own words whenever their physical condition permitted them to write their own stories.
Literary style has been a secondary consideration as we believe that a majority of the public would prefer to read the truth unabridged, than a story garbled by editorial tinkering.”
