I don't think the English get armoured spears in the campaign.

BTW, regarding my early comment on swords vs knights. I was besieging a castle last night and a defending unit of French knights (a general's unit with 2 HP) sallied out to charge my swordsmen pushing a siege tower. It was ugly but I am not convinced my spears would have done significantly better. It's a kind of mutual assured destruction. I guess the English just have to accept this kind of attrition.
