During the First Siege of Vienna in 1529, the battle wasn't fought only on the walls.
Ottoman engineers dug tunnels beneath the city, packed them with gunpowder, and detonated massive explosions to tear open the defenses. But Vienna's defenders responded with countermines of their own, racing underground to find and destroy the enemy tunnels before they could be fired.
It became a deadly battle beneath the earth—where a single tunnel could decide the fate of an entire city.
