Thanks, but I don't know if it is the Telegraph or the historian, but the article stinks nearly as badly as a urine dyed goat skin.
1) traditionally been depicted means (mostly) since some ahistorical romantic minded Victorian morons got hold of the idea. Not how they were portrayed at the time and after, or how modern historians and re-enactors portray them.
2) The Leine was an Irish garment of the period before and after, and oddly enough at the time of Bruce, more than half of Scotland WAS NOT FUCKING SETTLED BY HIGHLANDERS. OK? GOT THAT?
3) therefore someone is really trying to confuse things.
4) We do know what Scots of the period wore:http://members.iinet.net.au/~rmine/carlisle.html
See the blokes operating the trebuchet? Single leg hose and braies, with some sort of tunic or indeed shirt.
I will have to track down a copy of his book and see if he deserves to be mercilessly slagged off.
