I agree with rdonj. Dismounted knights would be possible, certainly -- but not practical. In addition to the Fatigue Factor, there's also the point that lance charges are a big part of why knights are so deadly. The lance charge is even
more important for Bretonnia, because the Bretonnian lances have been upgraded over the "standard" lance. Why on Earth would I want to give up my lance charge?
There's also the Mobility Problem. Knights on foot are S-L-O-W. Yuck. I'd much rather keep them on horseback so they can run down fleeing opponents.
Lastly, there's a thematicness (is that a word?) problem. Knights on foot are just elite heavy infantry. Yawn.... Dom3 already has a lot of elite heavy infantry. Anyway, Ulm does it better.
