Men of Harlech
"Men of Harlech" or "The March of the Men of Harlech" (in Welsh: Rhyfelgyrch Gwŷr Harlech) is a song and military march which is traditionally said to describe events during the seven year long siege of Harlech Castle between 1461 and 1468. Commanded by Constable Dafydd ap Ieuan, the garrison held out in what is the longest known siege in the history of the British Isles. “Through Seven Years” is an alternate name for the song. Now some associate the song with the earlier shorter siege of Harlech Castle around 1408, which pitted the forces of Owain Glyndŵr against the future Henry V of England."

"Men of Harlech" is sometimes mistaken for the national anthem of Wales. This is incorrect; the Welsh anthem is "Hen Wlad fy Nhadau" ("Land of my Fathers"). Still, the song occupies an important place in Welsh national culture.
Lyrics
Verse 1

Tongues of fire on Idris flaring,
News of foemen near declaring,
To heroic deeds of daring,
Call you, Harlech men.
Groans of wounded peasants dying,
Wails of wives and children flying,
For the distant succour crying,
Call you, Harlech Men.
Shall the voice of wailing,
Now be unavailing,
You to rouse, who never yet
In battle's hour were failing?
This our answer, crowds down pouring,
Swift as winter torrents roaring.
Not in vain the voice imploring
Calls on Harlech men.

Verse 2

Loud the martial pipes are sounding,
Every manly heart is bounding,
As our trusted chief surrounding,
March we, Harlech men.
Short the sleep the foe is taking;
Ere the morrow's morn is breaking,
They shall have a rude awakening,
Roused by Harlech Men.
Mothers, cease your weeping,
Calm may be your sleeping,
You and yours in safety now,
The Harlech men are keeping.
Ere the sun is high in heaven,
They you fear, by panic riven,
Shall, like frightened sheep, be driven,
Far, by Harlech men.


 It is the regimental march of several regiments historically associated with Wales. The Royal Regiment of Wales, now the Royal Welsh (UK), the Royal Canadian Hussars (Montreal) and the Governor General's Horse Guards, Canadian Forces are three examples. It is also the regimental march for two Australian Army Reserve units, the 8th/7th Battalion of The Royal Victoria Regiment and Sydney University Regiment where it is played as a quick march.

The music was first published in 1794 as March of the Men of Harlech in the second edition of The Musical and Poetical Relicks of the Welsh Bards. It first appeared with lyrics in Gems of Welsh Melody, edited by the Welsh poet, John Owen (Owain Alaw), published in London, England and Wrexham, Wales in 1860. The Welsh lyrics are by the Welsh poet John Jones (Talhaiarn), and the English lyrics by W.H. Baker. Since then, many different versions of the English lyrics have appeared.
