One little known fact ('cause I made it up) is that a web footed fowl played a part in a tragic episode of WW1 narrow gauge history.
Seems there was an arrogant French officer, high born and proud of it. Ordinary transport to and from his front line command position would certainly not do. For this purpose, he had constructed an opulently appointed armored car, complete with a kitchen and gourmet chef. On one particular trip back to the front, the chef had brought along a live duck (to ensure freshness!), destined to become the star attraction in duck a'lorange. On a moonless night, as the experienced crew rolled their odd little Decuauville engine through a vulnerable area of the front, the locomotive and car were practically silent, undetectable by the German listening posts which directed artillery.
But, suddenly, a sound was heard which brought down the awful fury of well directed shells, destroying locomotive and car, both.
For it seems that, though this Officer of privilege thought he was impervious to the dangers and drudgery of the battlefield, there was a quack in his armor!
