This chapter provides a narrative describing the experiences of two Australian veterans who fought at the Somme on the Western Front during World War I. One of these is ‘Pop’, as he was called by his grandson Peter, and the other is Pop’s close friend, Jack. The main battle they participated in was for the town of Pozières, where the First and Second Divisions of the Australian Imperial Force faced the formidable ‘dug-in’ German lines. The horrors of the ensuing battle are described in detail in Pop’s diary and are recounted here, as they explain his developing ‘shell shock’, or posttraumatic stress disorder (PTSD) as it is now called. Post-war, he continued to have nightmares and violent outbursts of unacceptable behaviour, which led to strained relationships with his small family and made his reintegration into society very difficult. Even by the time of World War II, more than 20 years after the battle for Pozières, Pop’s PTSD symptoms were still evident, and the nightmares continued.
