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.
Provisional Government of Saskatchewan The Provisional Government of Saskatchewan was an independent state declared during the Northwest Rebellion of 1885 in what is today the Canadian province of Saskatchewan. The name was given by Louis Riel. Although Riel initially hoped to rally the Countryborn, Cree and European settlers of the Saskatchewan Valley to his banner, this did not occur. The government, with the exception of Honoré Jaxon and Chief White Cap, had an entirely French-speaking and Métis leadership. Gabriel Dumont was proclaimed Adjutant General in which capacity he became supreme military commander, although Riel could, and did, override his tactical decisions. The Provisional Government was declared by Riel on March 19, 1885. It ceased to exist following the defeat of the Métis militarily during the Battle of Batoche which concluded on May 20, 1885. During its existence the government only exercised authority over the Southbranch Settlements along the South Saskatchewan River. Other major centres in the area such as Prince Albert, Saskatoon, and most First Nations reserves remained outside of its control.
