The document summarizes several memorial sites in France and Belgium that commemorate soldiers who fought in World War 1. It describes monuments such as Tyne Cot, Menin Gate, and Theipval Memorial which list the names of tens of thousands of soldiers who were killed or went missing in battles like those of Ypres and the Somme. Relatives of deceased soldiers often could not afford to inscribe personal messages on gravestones due to costs, resulting in many that only include a name or the words "Known unto God".
