Thomas hears rumors—false ones, as it turns…
June 1534 CE
Thomas hears rumors—false ones, as it turns out—that his father had been executed in the Tower of London and that the English government intends the same fate for himself and his uncles.
He summons he Council to St. Mary's Abbey, Dublin, and on June 11, accompanied by one hundred and forty armored gallowglasses with silk fringes on their helmets (from which he gets his nickname), rides to the abbey and publicly renounce his allegiance to his cousin King Henry VIII, Lord of Ireland.
The Chancellor, Archbishop John Alen, attempts to persuade him not to commit himself to such a rash proceeding; but the young lord's harper, understanding only Irish, and seeing signs of wavering in FitzGerald's bearing, commences to recite a poem in praise of the deeds of his ancestors, telling him at the same time that he lingers here over long.
Roused by this, he throws down the sword of state and rushes from the hall, followed by his adherents.
The council sends an order for his immediate arrest to the Lord Mayor of Dublin, who, however, has not sufficient force at his disposal.
The Earl of Desmond and many of his father's oldest and best friends reason with him; but he is not to be turned from his purpose.
As Vice-Deputy, Kildare has under his control most of the Pale fortresses, and large government stores.
Dublin Castle alone holds out for the King of England.
Lord Offaly calls the lords of the Pale to the siege of the Castle; those who refuse to swear fidelity to him he sends as prisoners to his Maynooth Castle.
Goods and chattels belonging to the King's subjects he declares forfeited, and he announces his intention of exiling or putting to death all born in England.
He sends messengers to his cousin and friend Lord Butler, son of the Earl of Ormond, offering to divide the kingdom with him if he will join his cause, but Butler refuses.
Several children of the citizens of Dublin in different parts of the Pale are seized as hostages for the good behavior of the city.
