Task: Question Answering
Input (English): Passage: On 24 May 1487, Simnel was crowned in Christ Church Cathedral in Dublin as "King Edward VI". He was about 10 years old. Lord Kildare collected an army of Irish soldiers under the command of his younger brother, Thomas FitzGerald of Laccagh. John de la Pole, 1st Earl of Lincoln, formerly the designated successor of his uncle the late King Richard III, joined the conspiracy against Henry VII. He fled to Burgundy, where Warwick's aunt Margaret of York, the Dowager Duchess of Burgundy, kept her court. Lincoln claimed that he had taken part in young Warwick's supposed escape. He also met Viscount Lovell, who had supported a failed Yorkist uprising in 1486. Margaret collected 2,000 Flemish mercenaries and shipped them to Ireland under the command of Martin Schwartz, a noted military leader of the time. They arrived in Ireland on 5 May. King Henry was informed of this and began to gather troops. Simnel's army—mainly Flemish and Irish troops—landed on Piel Island in the Furness area of Lancashire on 5 June 1487 and were joined by some English supporters. However, most local nobles, with the exception of Sir Thomas Broughton, did not join them. They clashed with the King's army on 16 June at the Battle of Stoke Field in Nottinghamshire, and were defeated. Lincoln and Thomas FitzGerald were killed. Lovell went missing; there were rumours that he had escaped to Scotland with Sir Thomas Broughton and hidden to avoid retribution. Simons avoided execution due to his priestly status, but was imprisoned for life. Kildare, who had remained in Ireland, was pardoned.
