Help remembering this bit from the Berserk manga?

I just can't remember/find this one part in the manga. There was this brutish guy and his bands of what I can only describe as Vikings/pillage-the-village-ing/super soldiers on steroids. They carried the dismembered bodies of their victims on poles with them and the leader was going to crush/violate Casca when he grew to the size of a giant, but Griffith and Guts stopped him (I think Griffith was there...)

The guy looked kind of Monkey-pig-bullish in a way, and he actually crushed one of his cronies' skulls between his thumb and forefinger.

Can you tell me what chapter or at least what STORY ARC this freak of nature is in? And his name? Thanks :3

I'm absolutely sure it's NOT Zodd...
