Line". During his service in Arras, in February 1918 he borrowed a staff car from a friend and visited his son's grave near Ypres, before returning to the library in Arras. Hornung was concerned about support for pacifism among troops, and wrote to his wife about it. When she spoke to Doyle about the matter, rather than discussing it with Hornung he informed the military authorities. Hornung was angered by Doyle's action, and "told him there was no need for him to 'butt in' except for his own 'satisfaction'." Relations between the two men were strained as a result. Hornung continued to work at the library until the German spring offensive in March overran the British positions and he was forced to retreat, firstly to Amiens and then, in April, back to England. He stayed in England until November 1918, when he again took up his YMCA duties, establishing a rest hut and library in Cologne. In 1919 Hornung's account of his time spent in France, Notes of a Camp-Follower on the Western Front, was published. Doyle later wrote of the book that "there are parts of it which are brilliant in their vivid portrayal", while Hornung's biographer, Alison Cox, described the book as "one of the best records of the war as experienced on the front lines". That year Hornung also published his third and final volume of poetry, The Young Guard.

He fell ill on the train with a chill that turned into influenza and pneumonia from which he died on 22 March 1921, aged 54. He was buried in Saint-Jean-de-Luz, in the south of France, in a grave adjacent to that of George Gissing.

When Hornung had still been courting Doyle's sister, Doyle wrote that "I like young Willie Hornung very much ... he is one of the sweetest-natured and most delicate-minded men I ever knew". Honouring him after his death, Doyle wrote that he "was a Dr. [Samuel]
