The emergence of the submarine was a major development in naval warfare. German submarine - or U-Boat - attacks against Allied shipping in the Atlantic and in European waters posed a major threat to the Allied war effort.
This print by French artist Jules Grandjouan attacks German U-Boats and their crews for leaving civilians to perish in the water.
The U-Boat here is about to abandon civilian men, women, and children to their fate. Allied propagandists used the supposedly indiscriminate violence of Germany's unrestricted U-Boat campaign to rally their own and neutral citizens in support of the war.
Qu'importe l'existence des Neutres! L'Allemagne est au dessus de tout!
