Latterly, C. S. Lewis made the random confession that ‘One of the golden Communions of my life was in a Nissen hut.’ Lewis spent a great deal of time at Royal Air Force (RAF) facilities during the war, where his efforts to undergird the work of RAF chaplains made a lasting impression. The talks he gave were Lewis’s first sustained attempts at addressing non-academic audiences and are responsible, at least in part, for refining the skills of a man who would become one of the most influential Christian writers of the twentieth century. Yet the story of Lewis and the RAF is largely unknown. This book seeks to bring that neglected part of his biography to light, and includes insights into how the Narnia tales began, viewing these particularly through the eyes of the evacuee children who stayed with Lewis and his household at The Kilns.
