RH Mottram (1883-1971) is best known for his classic Great War novels commonly known as The Spanish Farm Trilogy, published between 1924 and 1926. These were an instant success and were soon adapted into a film, The Roses of Picardy; the proceeds from these enabled his to retire from his banking job and take up writing full time.
He wrote numerous books (including a biography of his friend John Galsworthy) and was a published poet even before the war. Born and bred in Norwich, he went on to become Lord Mayor in 1953.
This guide to the battlefields of the BEF was published in 1936; the fieldwork was done in October 1935 and January 1936.
