While talking about Medieval war chronicles and how there were warriors able to kill bunches of their enemies, GRR Martin claimed that a Medieval knight would be fighting peasants with sticks. Which is obviously another use of the view of Medieval battles being armies of knights and press ganged rabbles of peasant levies. Which I know that going from the available evidence isn't the case for the majority of pitched battles. Especially since mass levies didn't come around until after the Medieval era.

So, is this another Victorian myth? I've seen it in other cases too.
