An archer would use his/her bow and arrow to fire at attackers attacking the castle. Most of the archers would try to protect the castle. Some would attack castles. They would try to aim for the head and maybe the feet. Some attack/defend on horses.

Knights would attack the castle. They would send a message to the king and say to surrend or something bad would happen. If they say never, then the knights would attack. This is how the knights would organize an attack. Thank you very much.
It was a good place to attack the castle from where they wouldn't expect an attack.
