I'm at the point in Assassin's Creed where I try to assassinate Robert de Sable on the cemetary in Jerusalem, but he notices that I am among the crowd and ambushes me with his men. I am having a hard time with that fight, it is far harder than the previous fights I got into.
I am constantly attacked by archers while I'm busy defending myself against the templar knights. The melee enemies are also pretty tough, I often fail parrying or counter-attacking them even when getting the timing right.
Any tips on how to win this fight? How do I prevent the archers from killing me and what do I need to know to effectively fight the templar knights?
