Historically, once a knight's lance broke or was dropped, was he stuck with whatever secondary weapons he had for the duration of the battle? Or did they have back-ups somewhere? I'm assuming a lance is too large to just holster on the side of your horse, so I guess you'd have to just drop it for good if you decided to switch weapons?

If so, then a more realistic M2TW would make it impossible for knights to use their lances again once they had switched to secondary weapons. What are ya'lls thoughts on that? I'm all for it, but I don't know if that's how it actually worked in real medieval combat.
