The Czech Catholics, who were led by Zdeněk of Šternberk, joined forces with Matthias in February 1469. Their united troops were encircled at Vilémov by George of Poděbrady's army. In fear of being captured, Matthias opened negotiations with his former father-in-law. They met in a nearby hovel, where Matthias persuaded George of Poděbrady to sign an armistice promising that he would mediate a reconciliation between the moderate Hussites and the Holy See. Their next meeting took place in Olomouc in April. Here the papal legates came forward with demands including the appointment of a Catholic Archbishop to the See of Prague, which could not be accepted by George of Poděbrady. The Czech Catholic Estates elected Matthias King of Bohemia in Olomouc on 3 May but he was never crowned. Moravia, Silesia and Lusatia soon accepted his rule but Bohemia proper remained faithful to George of Poděbrady. The Estates of Bohemia even acknowledged the right of Vladislaus Jagiello, the eldest son of Casimir IV of Poland, to succeed king George of Poděbrady.
