In 1573 he went to Spain to urge
Philip II to subsidise the exiles. He passed the following years at
Madrid, where he was granted a pension of 300
ducats. By 1575
James Fitzmaurice Fitzgerald had formed an alliance with Sir
Thomas Stukley to launch a projected
1578 Irish expedition, which Sanders was to have accompanied. The plan was supported by papal nuncio
Filippo Sega with the covert encouragement of King Philip. Fitzgerald and Stukley were to rendezvous at Lisbon, where King
Sebastian of Portugal convinced Stukley to participate in a campaign in
Morocco instead. Stukley abandoned the Irish invasion and sailed his troops to Morocco, where he was killed at the
Battle of Alcácer Quibir in August 1578. Sanders and Fitzmaurice landed a force of some 600 Spanish and Italian freelance troops with arms for 4,000 rebels and covert Papal support at
Smerwick harbour in Ireland, launching the
Second Desmond Rebellion. Sanders paraded the papal banner at
Dingle before trying to arm local
Irish clans and
Gerald FitzGerald, 15th Earl of Desmond and others seeking their backing, but they never linked up. The invasion fleet was immediately captured by
Sir William Winter, and in November 1580 the troops already at Smerwick were massacred by the
Irish Royal Army under
Arthur Grey, 14th Baron Grey de Wilton, after the 3-day
Siege of Smerwick. As Spain and the Papacy were not formally at war with England, Fr. Sanders and his men were declared
outlaws. Fr. Sanders himself escaped into the hills. Grey's report from Smerwick mentioned Sanders' involvement:
Execution of the Englishman who served Dr. Sanders, and two others, whose arms and legs were broken for torture. After spending months as a fugitive in the south-west of Ireland, Sanders is believed to have died of cold and starvation in the spring of 1581. ====
