Callan, County Kilkenny
Desmond, who had long been acting "with a certain disregard for the niceties of the law" now decided on open rebellion. In 1345 he presided at an assembly of Anglo-Irish magnates at Callan, County Kilkenny, ignored a summons to attend the Irish Parliament and attacked Nenagh. He was a formidable opponent, and for the next two years his defeat was the main preoccupation of the Crown. Desmond surrendered on a promise that his life would be spared; he was imprisoned and his lands forfeit. He was allowed to go under guard to England to answer the charges against him.
