Hark I hear the foe advancing
Barbed steeds are proudly prancing,
Helmets in the sunbeams glancing
Cymru fo am byth.
Men of Harlech lie ye dreaming?
See ye not their falchions gleaming,
While their penons gaily streaming
Cymru fo am byth
From the rocks rebounding
Let the war cry sounding
Summon all at Cambria's call
The haughty foe surrounding
Men of Harlech on to glory
See your banner famed in story,
Waves these burning words before ye,
Cymru fo am byth!
