The very zealous, but somewhat tactless, Bishop Zbynev of Cracow had decreed that all religious services in the town were to cease during the presence of the Hussite heretics. When during Easter week the Polish royal family wished to assist at the religious functions, the Bohemian envoys were requested to take up their residence in the suburb of Kaziměř, situated outside the city boundaries.[1] The bishop obstinately insisted on this measure, though many of the King of Poland’s councillors disapproved of it.

Probably as early as in March 1430, a large Bohemian force, consisting of 10,000 infantry and 1,200 horsemen, again invaded Silesia. Prokop himself, who was retained at Prague by deliberations that were then taking place there, took no part in this raid, of which it is unnecessary to give a detailed account.

Commanded by Velek Koudelnik and the priest Prokupek (Prokop the Lesser), they marched on the city of Tyrnau, where Sigismund was then residing. He was on the point of starting for Germany, intent on holding another of his numerous imperial
