“Tomorrow we hit the city for the last time. Before the bells at Petrov ring noon, Brno must be ours. If not, we will retreat. “- thus spoke the Swedish General Torstenson in the spring of 1645, when he had unsuccessfully besieged Brno for 4 long months. And that was after he thought he would sew up a victory within a week. Indeed, in the fortress of Špilberk in Brno there were 400 soldiers and he arrived with 18 thousand! The conquest of Brno meant very much to him – it was the only thing in the path to besieging Vienna.

How did this great battle take place? Who stood up to this Nordic leader? What was he about, where did he live and what trap did he think up for the Swedes? And why, then, does the bell on Petrov still ring noon at 11 am? History wrapped in ciphers, logic tasks and hiding places are awaiting you on the trail Battle of Brno.
