I suspect that he'd be trying to avoid being trampled. Outside of a skirmish, it won't be one horse and rider but lines of them, providing mutual support. Having stood in front of a re-enactment group of ALH on Walers, trotting slowly down the road (as a parade marshall, I was meant to be there!), I made damn sure to get out of the way pronto once they got within 20 feet. They're big!
A few more than I was in front of, but even more intimidating.
