Archbishop Fitzgibbon to give up his secrets in return for his passage back to Ireland, procured his arrest in Scotland. Invasion expedition On 1 October 1578, Don John died while on campaign in southern Belgium, of camp fever (typhus). His death disrupted plans for the invasion of England, but there was still stomach for supporting the Irish. In 1576 Fitzmaurice had been warmly received at Rome, where William Allen, later a cardinal, was also present, having presented to the Pope a plot for the invasion of England through Liverpool, with 5,000 musketeers under Stucley's command. Now, in 1578, the Pope provided Stucley with infantry and he set out with 2,000 fighting men. The force had, it was claimed, been raised by enlisting Apennine highwaymen and robbers in return for pardons and 50-day indulgences, the latter to be gained by contemplation of crucifixes supplied to Stucley. They were commanded by professional officers under Hercules of Pisano, and also Giuseppi who went on to command the Smerwick garrison at the beginning of the Second Desmond Rebellion. In sum, Stucley's ranks rose to 4,000. Stucley sailed for Ireland from Civitavecchia in March 1578. In April, he reached Cadiz with rotted ships, where he issued magnificent passports to Irishmen returning home, describing himself as Marquess of Leinster (a title bestowed by the Pope). Philip II sent him on to Lisbon, where he was to meet Fitzmaurice and secure better ships before sailing for Ireland. Here, King Sebastian of Portugal invited Stucley to take up a command in his army, which included Portuguese and German mercenaries, in preparation for an invasion of Morocco (an ally of England against Spain) in an attack upon the Moors. Stucley abandoned the Irish invasion, and destroyed the hopes of help in Munster. Stucley is said to have declared that he knew Ireland as well as the best and that there were only to be got there "hunger and lice". The Jesuit polemicist Nichola Sanders and Irish members of the expedition made their way back to Rome, and continued the now ill-fated invasion, deprived of most of its money and men by Stucley's desertion. On landing in Morocco, Stucley objected to marching straight away against a vast force of Moors and scorned the Portuguese king's troops and tactics. He reportedly fought with courage on 4 August 1578 at the Battle of Alcácer Quibir, commanding the centre, but was killed early
