Place 4 commanders plus Gena on the square just outside Bamar. On the next turn make them
attack one after the other. The point is to tire out and whittle down the dragon's HP so
that number 4 or 5 commander can kill it. You may let your decoy commanders run when
they're about to die. Then move the next one in for the kill (or the next)
