The first half of this book was devoted to introducing the characters. Then, about mid-book, the author expanded with more details about the young immigrant American men. I was starting to be bored reading the first half when the author began to describe what happened to each man during World War I. The resulting picture is an extraordinary history of a time now quickly fading into the past.
The Great War created ten million dead people in just four years (1914-1918). It was the "War To End All Wars".
The peace lasted about twenty years.
