The novel is based on the Treaty of Fontainebleau, in which Spain and France agreed that they would unite to conquer together Portugal and, once achieved, they divided it up. But to think that Napoleon would pass through the peninsula without trying to conquer it was naive. The city of the four rivers was the victim of a great tragedy that caused thousands of deaths and the destruction of a large part of the city. The novel speaks of the unknown but decisive role that the women played in the defense and recovery of the city, and how they organized themselves heroically in what was called “The Barbarians”, very recognizable because they wore a red ribbon tied on their arm, as red as blood, and because, fiercely, they fought nonstop to defend their home.
