Durelin,
Yes, please do the wrap-up for the battle. That would be great.
Firefoot,
Yes, Grask is the only "named" orc child who is actually being played. But perhaps out of the fifteen orcs, there would be one more who has been a NPC who is a child? This seems like a good idea since several posters made reference to children as a "softening" agent.
Also, it would not be a bad idea if someone "picked up" another orc and actively played them.....man, woman, or child.
