This battle is fairly easy with the right tactics. As Heartseeker said it is more difficult fight if you enter from the sewers but for shear conveinence sake I prefer to do it from the sewer entrance as I like to do a certain quest in the sewers first. I asume that's also the entrance you have entered from.

It would help to know who's in your party but I'll tell you how I do it. As soon as the dialogs over I have Nalia cast hold person on the cleric. He's a pest because he likes to summon skeletons. That should take him out of the fight, it should work but if it doesn't reload. Next I have Anomen cast hold person again this time on Captain Hagean. I then send my best warrior to take out the held Captain killing him fairly quickly and my other melee fighters take out the cleric. Once those two are dead my fighters all join together and kill the remaining guards who are quite weak. Battle over.

In the next fight with the two wizards and guards I find it is important to take out the wizards fast. I have Yoshimo hide in shadows and sneak up behind the Gnome. Then I have all my other characters charge the slaver guards. Once there spotted and the fight starts I have Yoshimo backstab the Gnome. Usually these means he starts to panic and runs away so you can pick him off at your leisure. First though you need to kill the other wizard. Cast dispel magic on him to remove his protections,(this will also remove the gnomes if he didn't panic). I have Nalia blast the human wizard with a wand of lightning I found until he dies I then have my best melee fighters kill the gnome(more difficult if he's not panicing and he has two mirror images memorised so you may need another dispel magic). Once the gnome's dead it's a simple matter of killing the remaining guards who are quite weak.

Good luck and I hope this helped!
