Unfortunately your situation will get worse. The hallway you have to go down to continue the game is blocked by FOUR skeletal mages. It's not too far away from where you're fighting now.

I found it impossible to do on "Action" difficulty with two melee warrior characters. They run around way too fast and kill you before you can manage to take out 1 or 2 of them. I restarted the game because of this point <img src="/ubbthreads/images/graemlins/disagree.gif" alt="" />

Second time around I made one of my guys and archer... which made the game MUCH easier. Put the archer on aggressive, have him as your second character, and poof! You got Diablo 2 with an archer hireling. He easily took out the pesky mages because he didn't have to run around all over the place to catch them.
