Whose desecrated graves betray'd their track;
On Albion's shore, unseen, the invader stept;
Secret, and swift, and terrible it crept;
At noon, at midnight, seized the weak, the strong,
Asleep, awake, alone, amidst the throng,
Kill'd like a murder; fix'd its icy hold,
And wrung out life with agony of cold;
Nor stay'd its vengeance where it crush'd the prey,
But set a mark, like Cain's, upon their clay,
And this tremendous seal impress'd on all,
