Thanks for all the replies. Nick and Potatoe Man are particularly helpful. So I think I have made the mistake of letting my chokepoint city falling in hostile dominion. (I get a temple there but I have not got enough priests to make sure that it is in my dominion).

So my wraith lord flees because it is in a hostile dominion. If in a friendly dominion, it would not flee even if it takes damages?

I think during morale check, if all the units commanded by a commander flees, the commander would flees. So I should never allow an sc to command any unit? You know, I like to get my wraith lord to summon ghosts. And it appears that my wraith lords always start battle with a handful of undeads with him. Does it make it impossible to stop him fleeing when all those crappy units get killed in a turn or two?

One more thing to confirm: My sc did not flee because he gets tired, right? Undead with 0 encumbrance does not get tired with any heavy armour, right?

I like the wraith sword because I was once defeated by the heroes (two trolls, a mage, a dark knight and someone I cant remember) badly. I kill four of them with my army the first time I get beaten. The real big disaster comes later. All the weapons held by the killed four goes to the remainging troll. The wraith sword initially comes from the dark knight adds hp to him everytime he kills a guy of mine in a second big defeat. I think he kills a big army of a few hundred units of mine in my second defeat and hence I think a life drain weapon is the key to a sc.
