The Legend of the Swedish Siege of Brno

The siege of 1645 is the most famous event in Brno's history. General Torstenson led 28,000 battle-hardened Swedish soldiers. The city had fewer than 1,500 defenders. Despite these odds, the people of Brno refused to surrender. They fought from the walls and from deep underground tunnels.

By August, Torstenson was frustrated and losing men. He made a final vow to his officers. He said if the city did not fall by noon, he would leave. A local scout heard this and warned the defenders. When the final assault began, the city was in trouble.

The bell ringer at the cathedral saw the danger. He decided to ring the noon bells at 11:00 AM. Torstenson believed it was noon and stopped the attack. The Swedish army marched away shortly after. This trick is why the bells still ring early today.
