ベオグラード包囲戦
In retaliation for Mezid's defeat and death, Shehabbedin, the beylerbey of Rumelia, invaded Transylvania. In the Battle of the Iron Gate, near the Danube, Hunyadi wiped out Shehabbedin's army in the second greatest victory of Hunyadi's career, surpassed only by his rout of the Ottoman sultan's army in 1456 at the Siege of Belgrade.
