where in the world did he get those foolish mercenaries? she had the reputation of a sword master, Eusto too, Felix was known as a monster and I'm guessing the insignificant rest are Eustos subordinates, so elite as well - even if you thought that julia was not at the best anymore after the last two years, the rest surely is - did noone thought about attacking with (cross)bows?
but smart move of the author to let her duel with Eustos to get a feeling for her innate but unused to abilities
