Sigismund arrived at noon, October 31 and found that the castle had already surrendered. He initiated the Battle of Vyšehrad, in which his forces were defeated. Radical Hussite priests called for the Imperial corpses to rot on the field for three days, but the army of the Prague Hussites ignored it. The castle was sacked and on June 21, 1421, Hradcany Castle was also taken by the Prague Hussites and similarly ransacked.
