COME FROM A LONG LINE OF PROUD AND PUGNACIOUS PEOPLE that I can trace back to Scotland, home of one of the world’s great warrior cultures. The Romans invaded Scotland (Caledonia) several times in the first three centuries AD, but the fiercely independent clans fought back with a fury that impressed even the mighty legions. When there were no Romans or British left to fight, the clans fought each other. Their leaders were willing to lead from the front and die in the face of overwhelming odds and certain defeat.
