Answer:
After some six weeks of living with cold-blooded companions, by the time of my execution, she risked to be defeated in order to save me.
Step-by-step explanation:
The word fatting gives the idea of living with them, it is not referring just to eat. The word savage describes cruelty and back in those times, people used to have courtiers = companions. Beat out is a phrasal verb that means to defeat someone in this case "her own brains" = her intelligence =her to save his brain= him.
