The Day of Wrath A Story of 1914
This is a book which had gone out of print, but is now in the public domain and is available on demand. This edition has been reformatted, retyped and designed.
It depicts Belgium at the beginning of the war. Basically, it could be described as an adventure story in a war setting, but that setting is based on reality - so that the book is interesting because it does give some insight into the state of affairs in Belgium in the early weeks of the war.
