Task: Question Generation
Input (English): Passage: On 5 February, Uskok captain and baron Jobst Joseph von Thurn  led an army of 500 Uskoks from Kostanjevica and some German soldiers that defeated a rebel detachment of Nikola Kupinič at Krško , which was the first larger rebel defeat. This rapidly weakened the rebellion in Carniola and Styria. The next day, another rebel force was defeated near Samobor. On 9 February, the decisive Battle of Stubičko polje was fought. Gubec and his 10,000 men resisted fiercely, but after a bloody four-hour battle the baronal army defeated and captured Gubec. The revolt failed. Retribution was brutal: in addition to the 3,000 peasants who died in the battle, many captives were hanged or maimed. Matija Gubec was publicly tortured and executed on 15 February. Officers Petar Ljubojević, Vuk Suković and Dane Bolčeta , and Juraj Martijanović and Tomo Tortić  were all sentenced to life in prison and lost all their property. Mogaić was killed in the final battle, and Pasanec was most probably killed in one of the skirmishes in early February, while Gregorić managed to escape, but was captured within weeks, brought to Vienna for interrogation, and executed in Zagreb in 1574.
Output (English): In what year did von Thurn lead an army that defeated the rebel detatchment at Krško?
