entered into this plan. They had numerous partisans in Prague, among whom were John Rak, chief judge of the old town, and several councillors, both of the old and new towns. The accounts of this attempt to liberate Korybutovič are very contradictory, but it seems probable that the plan was betrayed to the town-councillors by Lord William Kostka, one of the Utraquist nobles; finding less support among the Hussites than they had hoped the Utraquist nobles had confided their plan to some of the lords “sub una.” The latter then proposed that as soon as Prague had been captured Sigismund of Hungary should be proclaimed king. This was, of course, opposed by the Utraquist nobles, who were faithful to the articles of Prague. When the nobles arrived at the city gates on September 6 they found them open, but as soon as they reached the market-place they were attacked by large numbers of townsmen. As their force consisted only of 600 horsemen resistance was hopeless, and they could only attempt to escape. Some succeeded in doing this, but many were made prisoners, and some of them were afterwards decapitated.
Though this attempt had completely failed it resulted in the liberation of Prince Korybutovič. The leaders of the advanced party in Prague, thinking his presence in Bohemia more dangerous to them than his absence, caused him to be liberated on September 9 and conducted under escort across the Bohemian frontier.
