On March 23rd, 1918, Paris suffered bombings once again. But this time, the city was not attacked by airplanes, but by cannons whitch had been installed 120 kilometres from capital city, in the Aisne département.
The very efficient "Pariser Kanonen", which were called "Berthas" by the French, were producted by Alfred Krupp's armaments factories in Germany. Canon shots fired until August 9th, 1918, in a view to demoralizing the Parisian population.
These cannons, which were dismantled before the Armistice end destroyed in Germany, never fell into the hands of the Allies and would make deep and long-lasting imprints in the collective imagination and memory on the French.
