Speaking of "that bloody wreck known as World War I," an excellent memoir that recollects the era is Goodbye to All That
, by Robert Graves. However, it suffers from a lack of fishing.
But Nick Lyons long ago recommended in the pages of Cal Fly Fisher
a slender volume entitled Golden Days
, by Romilly Fedden, who had served with the BEF on the Western Front. His is a memoir about fishing the Breton countryside prior to the start of the conflict. The war is mentioned, but only in passing, as Fedden was much more interested in depicting a world that he clearly loved, and that was quickly vanishing.
