I've lost count of the number of times I've read people posting along the lines of:

"build CKs in Ile de France and dismount them in battle to get +1 valour CFKs!!!!!!111!!11"

How they've reached the conclusion that the dismounted units actually get this bonus is any ones guess...

As Martok has put it, these are useless valour bonuses that were left in place by the developers whom had obviously intended to include foot knights as a trainable unit then resolved to leave them as dismounted units.
