The War Diary of the Master of Belhaven – by Lieutenant-Colonel the Hon. Ralf Hamilton. A rarity. I was given this back in 2015. It is a wonderful read and goes in the backpack particularly for descriptions around Maricourt, Carnoy, Trones and Bernafay Woods, attacks on Guillemont. The narrative is clear, honest, somewhat matter of fact and descriptions of horror are vivid.
