Task: Question Generation
Input (English): Passage: Vest Recklinghausen was first mentioned in 1228 as a fiefdom of the Archbishopric of Cologne and thus it belonged to the Electoral Rhenish Circle. The administrator lived in castle Westerholt, located in Herten. From 1446 to 1576 it was used as collateral, first pawned to the lords of Gemen  and after 1492 to the Lords of Schauenburg and Holstein-Pinneberg, who pawned the territory back to the Archbishops of Cologne in 1576. During the Cologne War , Vest Recklinghausen was occupied and sacked several times by troops from both sides of the conflict. In 1583, although much of the territory was already Protestant, the Calvinist Elector of Cologne, Gebhard, Truchsess von Waldburg and his wife, Agnes, ordered the destruction of the icons and decorative elements of the churches. In 1584, the territory was sacked again, this time by the competing archbishop, Ernst of Bavaria. In 1586, the territory was invaded by Martin Schenck and Hermann Cloedt, who caused great damage to the farms and small villages, and were besieged by Claude de Berlaymont, also known as Haultpenne, in the city of Werl.
Output (English): How many years after being sacked by Ernst of Bavaria was Vest Recklinghausen invaded by Martin Schenck and Hermann Cloedt?
