So I found an old save with our team before we fought the three skeletons. We were all level 4 with Red Prince getting level 5 during the fight and our rogue being close to level 5. I just did the fight another time and the best they could achieve was half killing my mage, all other did hardly lose their armor.
Magister with Cork and at the harbour are still alive, same goes for Court. Not sure if we fought the hound master, but we killed the butcher and his golems and looted all the paintings to buy stuff and killed the 4 skeletons at the beach.
Enemie mage died round 2, rogue round 3 and warrior round 4.
Here you can see our setup:
