How did Vlad the Impaler defend Europe against Muslim attacks?

Vlad the Impaler, a 15th-century ruler of Wallachia, is known for his brutal tactics against both internal and external threats, including Ottoman incursions. He employed guerrilla warfare, ambushes, and scorched earth strategies to disrupt and deter the advancing Ottoman forces. His infamous reputation for impalement instilled fear and served as psychological warfare, discouraging potential attackers. While his methods were often ruthless, they contributed to the temporary stabilization of the region against Muslim expansion during his reign.
