Just weeks before the armistice, Raymond Chandler was transferred from the Canadian Expeditionary Force to the RAF and sent to RAF Waddington.  Here, he recovered from his wounds and tried to come to terms with the loss of his comrades; he also began his serious drinking.  The end of the war brought an end to his flying career - but not his drinking.
During this period, he wrote the fragment The Trench Raid in which he first explored  the Smell of Fear.
