Distance marching rates, infantry v cavalry

[Vindex]

Don't know the Junklemann reference (and would be interested to know too!) but a quick thought is potentially his supposition/argument is based on the logistics of cavalry - if you don't take fodder with you, you have to spend time gathering it or let the horses graze for a few hours; a handful of grain and nothing else isn't good for their digestion! And a fit horse eats quite a lot.

And water , of course...

Edit: there is always this thread - haven't the time to wade through it now...
