True, the army Olav fought were called "bondehæren" or "the peasant army". But by this, they didn't mean Olav's royal army figthing a bunch of men with heyforks. This was a battle betwen the king who wanted a kingdom, and chieftains who fougt for the old system with independent "Gårder" (Can't find a good english word for it, but it's kind of a huge farm with fields, woods, hunting-grounds aso). So the "bondehær" was a coalition of chieftains fielding their hird, and other unit's avalable (as they had allways been doing when going to war.)
