A Parisian gang war over a woman

The Manda-Leca Affair was a gang war led in Paris by two rivals in love with the same woman. The successive armed clashes between their gangs inspired many indignant journalists, who compared these acts of violence to those of the Far West. The two rivals ended up being sentenced to forced labor and sent to the penal colony in French Guiana, while the woman experienced brief theatrical and artistic notoriety.
