Every time I hear that verse I have the urge to go out and blow up a Nazi rail line (preferably one leading into Normandy).
Use in World War II
“In preparation for Operation Overlord, the BBC had signaled to the French Resistance that the opening lines of the 1866 Verlaine poem “Chanson d’Automne” were to indicate the start of D-Day operations. The first three lines of the poem, “Les sanglots longs / des violons / de l’automne” (”Long sobs of autumn violins”), meant that Operation Overlord was to start within two weeks. These lines were broadcast on 1 June 1944. The next set of lines, “Blessent mon coeur / d’une langueur / monotone” (”wound my heart with a monotonous languor”), meant that it would start within 48 hours and that the resistance should begin sabotage operations especially on the French railroad system; these lines were broadcast on 5 June at 23:15.”
