What to read after Missing in Action Presumed Dead WW1?

Chris Clark, a soldier from Sheffield, is fighting on the Western Front. Siggi Haas, a soldier from Berlin, is also fighting on the Western Front. They were just ordinary young men before the war started and now, their lives have been cast to Fate. Chris worked in a steelworks and was happy with his lot. Siggi was an assistant history teacher and looking forward to becoming a good teacher. They were uprooted from their normal environment and thrust into a world of war, as so many others were. They knew nothing of war and assumed it to be something gallant and adventurous. They even assumed they might enact some heroic deed. There were so many heroes in the Great War and so many battles that I have not mentioned because this is a story based mainly, but not entirely, on the Western Front. It concentrates on the events surrounding Chris and Siggi, being the British Army and the German Army. The words of the soldiers, sailors, airmen and leaders have been taken from letters, diaries, memoirs or documents — real people experiencing real events. However, Chris Clark, his family and friends are fictional, as are Siggi Haas, his family and friends. Some of the men in this book died in the Great War, some lived and some endured something in between living and death.
