"Salamis de rats. Sauce Robert. (rats)"
Conclusion! And we should hope so.
Thanks to the web site "Military History Of the 20th Century" a number of images from the Great War [WW1], proud Frenchmen with their displays and collection of DEAD TRENCH RATS!
That small dog in the arms of the man on the left a terrier, that most effective opponent of the rat. Terriers bred specifically to be fearless and extraordinary hunters and killers of the rat.
The hotel of the dead rat! Indeed!
I hope and prey these Frenchmen did not contemplate cooking and eating these rats! Spitted rat on the end of a bayonet all the rage by the occupants of the Commune, during the Franco-Prussian War, 1870. The besieged and starving residents of Paris resorting to extraordinary means during times of extraordinary circumstances. Please keep in mind those trench rats probably at one time or another had dined on HUMAN FLESH!!
