The Scots began their advance as a result of the attrition of the English artillery, in doing so they then had to contend with bows as well, a contemporary account states;
‘They were so surely harnessed with complete harness, German jacks, rivets, splents, pavises and other habiliments that shot of arrows in regard did them no harm.’
It would therefore appear that they advanced at least part of the way with pavises. How on earth you do that in 3/4 to full armour (it was only the front ranks) downhill in wet weather is beyond me.
I’ve often wondered if it was something the French captains recommended.
