There are three essential works for anyone interested in going deeper into Tolkien’s writing and thought: Humphrey Carpenter’s biography, Tom Shippey’s philological appreciation, JRR Tolkien: Author of the Century, and John Garth’s Tolkien and the Great War. While Tolkien, famously and justly, abhorred the mining of an author’s life for the coal seam of his literary material, Garth’s study of Tolkien’s war, and that of the other three members of the youthful coterie that had gathered around him, the TCBS, is both an appreciation of the subtle weaving of thought, experience and action, and an examination of that generation, raised at the height of Empire, who bled out in the holocaust of the First World War. If anything, the two members of the TCBS who died in France, GB Smith and Robert Gilson, are portrayed even more vividly than Tolkien himself. It is clear that Tolkien was a writer who particularly required the frank and unvarnished feedback of men whom he admired and who resonated with him: most famously CS Lewis, who cajoled and encouraged the writing of The Lord of the Rings but, Garth’s book shows, Smith, Gilson and Wiseman similarly played midwife to the birthing of Middle-earth through their talks, discussions and shared ideals. For someone who has always been solitary in his creative endeavours, I find this aspect of Tolkien’s work fascinating and inscrutable. I’m also, I think, rather jealous. Would that I might say, “What! You too? I thought that no one but myself…”
