 Viscount Clare: This is the Lord Clare to whom the following lines refer:
"When, on Ramillies' Bloody Field,The baffled French were forced to yield,
"The victor Saxon backward reeled Before the charge of Clare's Dragoons.
CHORUS. "Viva la, for Ireland's wrong!Viva la, for Ireland's right!Viva la, in battle throng,
"For a Spanish steed, and sabre bright!"
 Fontenoy; At Fontenoy the Irish saved France from defeat when the battle was almost won by the English. As a last resource, Marshal Saxe ordered up his last reserve, the Irish Brigade, of which this Viscount Clare held the command:
"Lord Clare," he says, "you have your wish; there are your Saxon foes!" The Marshal almost smiles to see, so furiously he goes! How fierce the look these exiles wear, who're wont to be so gay: The treasured wrongs of fifty years are in their hearts to-day: The Treaty broken, ere the ink wherewith 'twas writ could dry, Their plundered homes, their ruined shrines, their women's parting cry, Their priesthood hunted down like wolves, their country overthrown; Each looks as if revenge for all were staked on him alone."On Fontenoy, on Fontenoy;" nor ever yet elsewhere Rushed on to fight a nobler band than these proud exiles were.
