Dueling and Scottish fighting are two completely different things. Duels are formal acknowledgments, had judges, and structured so each participant had equal opportunity. Scottish southerners engaged in fights with the intent to maim, would always seek to attack when the target was vulnerable, used weapons like knives, and often would gang up on the individual.
