That would be logical except that many of the best fighters are already badly wounded (Osric, Tarando, Thoronamir and Veryadan), Menecar is dead and Aidwain is already injured with a broken leg. That will only leave Silrûth and Luinien in the rear guard against a still potent orcish strike force supported by trolls. And not forgetting many horses have either been slaughtered or have fled in terror.

If the hasty retreat covered by the rear guard is to be realistic, then someone with alot of role-playing experience and good writing skills must end it.
