I recall a great anecdote from the Swedish campaigns in Polish Prussia where they just stole a column of troops marching to reinforce the other side. I suppose this is the advantage of mostly mercenary troops?

We should not exaggerate the "nationalism" of medieval soldiers - if their patrons and lords switch sides, most of them are happy to switch sides as well (I expect pressing people into service would probably represent persuading their leaders, rather than driving them on in hordes, Mongol-style?).
