It was written and recorded by Watt Nicoll (ca 1970 I'm guessing), but I wouldn't necessarily rely too much on its historical accuracy - songwriters are not on oath when creating. The border folk were not renowned for being peaceful.

BORDER LANDS
(Watt Nicoll)

Border lands, Border lands
There was never a gun on the Border run
Till they shed the blood of a Border man

Now the English were ruled by a German man
Dundee rode with a Highland clan
And in between lying low and free[?]
Were the peaceful folks of the Border lands

Ah we're damned if we fight with an English might
Nor do we stand with the Highland clans
But we'll stay home and mind our own
We're the peaceful folks in the Border lands

So south came Dundee from the high, high land
North came William with his military plans
Raped and burnt, made a battle front
And the blood ran red through the Border lands

So the Lindsays, the Ramsays, the Scotts, and the Hays
Elliots, Kerrs and the Johnsons they[?]
That drew their swords, aye and shed the blood
Of every man who passed that way

Dundee hated all the lords in the south
His name courted[?] curses from these English mouths
But they rode as one on the the Border lands
And left tears and grief in every Border house
