The Governor-General of the United Provinces during the Seige of Sluis died during which time frame?
Siege of Sluis (1587) The Siege of Sluis of 1587 took place between 12 June and 4 August 1587, as part of the Eighty Years' War and the Anglo-Spanish War (1585–1604). On 12 June 1587, Don Alexander Farnese, Duke of Parma "(Spanish: Alejandro Farnesio)", Governor-General of the Spanish Netherlands, and commander-in-chief of the Army of Flanders, laid siege to the strategic deep-water port of Sluis, defended by English and Dutch troops under Sir Robert Dudley, Earl of Leicester, Governor-General of the United Provinces, and Sir Roger Williams. On 24 June, the bombardment began, and on 4 August, after of 13 days of constant fighting around the walls, the English garrison surrendered.Parker/Martin p. 126–127 The loss of the English-held port of Sluis revealed the inability of Leicester to assert his authority over the Dutch allies, who refused to cooperate in relieving the town, and led to recriminations between the governor-general and the States of Holland.
