Best to use a depleted unit for that or they struggle to get close and attack.
Also seems that swords and daggers (besides using artillery and flaming missiles) are best for the job.
Peasants do a bang up job of this. In contested areas I keep several units of peasants just for wall defense and artillery destruction. My present game Florence has been attacked 5 times. My peasants took out the arty each time.
