[1] A female bard named Bravura is being hired by the women of the village, who think that Cacofonix is giving their children a poor education.

Meanwhile, Julius Caesar, to take over the village, sends his agent Manlius Claphamomnibus, with orders to bring the "secret weapon" over the ocean discreetly.

Claphamomnibus's ship lands at Gaul, and he reveals the secret weapon: female legionaries, whom the Gaulish men would refuse to fight for fear of being dishonored.

His initial step is to have Cacofonix sing onomatopoeia in the forest, causing rain and scaring all animals (in one scene exposing a dragon), which in turn terrifies the female Roman scout parties and delays their assault.

Julius Caesar is made the laughing stock of Rome, and Bravura leaves for Lutetia, reconciled with Asterix.
