No links (because of the high probability that the following statements are completely false), but apparently the ancient Pict warriors ran into battle completely naked, covered with chalk to make themselves look like ghosts. When Roman auxiliaries were able to coax these ancient Scots to come out of the forest and fight, hordes of naked, screaming Scotsmen were no match for Roman cavalry. On the other hand, legionaries were extremely reluctant to venture into the dark Caledonian woods, so after 400 years of light skirmishing, the Romans left on their own accord.
The first reference to Scottish Highlanders using bagpipes in anger is the Battle of Pinkie Cleugh, approximately 1400 years after Hadrian's Wall was built. Who knows how world history might have been changed if Scots had been less reticent about keeping their clothes on and started squeezing air bladders to make it sound like the screams of tortured demons in order to frighten the daylights out of their enemies?
