I am re-listening to the Dan Carlin series on WW1 and I find it pretty implausible that a library with ancient texts would survive to the degree that a soldier could do research in it, regardless of the nonsense

Edit: did 30 seconds of googling. J.r.r Tolkien was in the battle of the somme, so north east France and got tench foot and was recovering for the rest of the war. Austria was part of Austria-Hungary at the time so a member of the central powers. I suppose it could be plausible that after Austria Hungary collapsed (I forget honestly how the war ended) UK troops could have found their way into Austria, but I really still have my doubts
