Richard Gwyn, John Hughes and Robert Morris were indicted for high treason in October 1583 and were brought to trial before a panel headed by the Chief Justice of Chester, Sir George Bromley. Witnesses gave evidence that they retained their allegiance to the Catholic Church, including that Gwyn composed "certain rhymes of his own making against married priests and ministers" and "he had heard him complain of this world; and secondly, that it would not last long, thirdly, that he hoped to see a better world [this was construed as plotting a revolution; and, fourthly, that he confessed the Pope's supremacy." The three were also accused of trying to make converts.
