The real Norfolk commotion ended with a battle when the lawful authorities took the threat seriously and sent, 3 weeks after the uprising officially started, an army roughly equal in number to the rebels. Sure, the first response (15,000 rebels vs 1,500 soldiers, fighting in the worst situation logistically) was a victory for the rebels (they took the city) as numbers are akin to the disparity mentionned in this thread (many peasants vs a handful of defenders) but as soon as the authorities could act, they sent an adequately sized response (15,000 soldiers vs 15,000 rebels) and it ended with 3,000 rebels killed and 250 soldiers killed. A few hanging happened and order was restored. The rebel's strategic goal of stopping enclosure in Britain wasn't met.
To succeed, a peasant uprising must not only make the local lord flee (and maybe turn the local spellcaster to their cause). They must become accepted by the rest of the kingdom, who as a clear interest in enforcing the social order and not letting revolts prosper.
