How to kill the guards that are on horses easily

assassins-creed-brotherhood

I always whack away at a mounted guard, but it seems I only hit the horse. When I'm done, the guard is still chilling on the horse.

What's the best way to defeat these mounted guards?

Best Answer

One of the 'loading tip' says that when they come towards you, you have to be equipped with a one-hand sword and hold R1 (PS3 version). You'll block the charge and put the horse down. It's easy from there to execute them when they're still down.
Another easy way is to use pistol, crossbow or (spoiler below, hover your mouse)

even less work by calling your assassins friends when your brotherhood is created.
