Luce on the War

In the Irish Times newspaper,^{(Nov. 11, 1929, p. 4)} there's a report by an anonymous journalist about a sermon given by A. A. Luce in Belfast Cathedral (on the occasion of the dedication of a war memorial lectern). Luce is there said to have criticized  recent war novels, and 'one in particular', on the grounds that they 'made two grave errors -- they overstated the physical horrors of war, and they did less than justice to the morale of the soldier'. Luce chides one author (unnamed) for having 'compressed the suffering of the Army into the imaginary experience of his hero'. There follows this quotation from Luce's sermon:

In my judgment, to depict the soldier's life as intolerable horror is a propagandist attempt to intimidate the soldier's son. Another and more serious blot upon recent fiction is the attempt to blacken the soldier. To say that war does, and must, develop all the animal in man and leave other qualities undeveloped is a libel on the dead and the living. Could the golden record of 50 000 Irishmen dedicated that day speak with tongues, the war novel of 1929 would hide its head for shame. Men would say that their comrades fought a clean fight and fell honourably dead in honour's cause. War fiction would be soon forgotten, but war facts would speak to generations yet unborn.^{(Irish Times, Nov. 11, 1929, p. 4)}

No authors or novels are named in the report, but Robert Graves' Goodbye to All That was published in 1929, as was Richard Aldington's Death of a Hero. Outside the UK, both Hemingway's Farewell to Arms and Remarque's All Quiet on the Western Front appeared in 1929.
The claim that the novels overstated the physical horrors of the War reminds me of Wittgenstein's offhand remark to the effect that the War wasn't really as bad as people thought it was. (I can't locate a source that gives Wittgenstein's exact words.)
