It is impossible in a small volume to write the history of the World War in even a partially exhaustive manner.

Nor is that the object of this book.
Rather than to deal with generalities, its purpose is to describe separate events of which I had intimate knowledge, and individuals with whom I came into close contact and could, therefore, observe closely; in fact, to furnish a series of snapshots of the great drama.
By this means the following pages may possibly present a conception of the war as a whole, which may, nevertheless, differ in many respects from the hitherto recorded, and possibly faulty, history of the war.
Everyone regards people and events from his own point of view; it is inevitable.

In my book, I speak of men with whom I was in close touch; of others who crossed my path without leaving any personal impression on me; and finally, of men with whom I was often in grave dispute.

I endeavour to judge of them all in objective fashion, but I have to describe people and things as I saw them.

Wherever the description appears to be at fault, the reason will not be due to a prematurely formed opinion, but rather, probably, to a prevailing lack of the capacity for judging.
Not everything could be revealed.
