Dead General's and their bodyguards.

[Didz]

I usually use them as disposable heroes once the general dies (suicide charge). Better they die serving the unity than just go away.

Um! thats the point...they don't go away.

Like you in previous TW titles I got used to using any surviving general's bodyguards as suicide troops if I lost my general in battle. It was sensible because as you say any survivors simply dissappeared after the battle anyway, but it seems they don't anymore.
