Charmion, it is totally unfair and incorrect to include the aforementioned regiments as mercenaries. The Scottish and English parliaments were united in 1707 and after that date all Scottish and English regiments were classed as belonging to the British army. I would class the Black Watch more as Quislings as they were raised to police the highlands but they were still part of the British army. Their tartan is also known as The Government Tartan, hardly mercenaries.
