Arrows v artillary

[Didz]

I was surprised to hear a historian claim that Trebuchet were not very good at destroying castle walls. He reckoned that for the most part they were used to lob stuff into the castle rather than at it.

I'm not sure that he's right in fact, I'm sure that they were tested and shown to be pretty effective. (though not as effective as in MTW2, of course)
