A little tactical advice if I may.
When charging (or being charged for that matter) by a single character on his own, and unless you don't have the tools to kill him, you should deny the challange. In this case, your AC wouldnt fight, but then the rest of the unit would make the hits and hopefully clean him up.
And if you won on the turn you charged, you would still have your cover save (Jink + Skilled Rider)
