Long ago, a big fight happened at a fort. 


In 1456, a big fight happened at Belgrade. 

A leader named John Hunyadi fought to save Belgrade. He spent his own money to fix the fort. He also gathered a large army. Some were trained soldiers. Others were peasants. 
The fight lasted for many weeks. On July 14, Hunyadi fought a battle on the river. He broke the Ottoman ships. This let food and men reach the city. On July 21, the Ottomans made a final attack. The defenders used fire to stop them. 
The Ottoman army had to leave on July 22. This win helped keep Europe safe for 70 years. It also showed that new guns and cannons were very important in war. Hunyadi was a hero, but he died of sickness soon after.

Sultan Mehmed II prepared an enormous force to break these defenses. He brought a massive army that modern researchers estimate was between 60,000 and 70,000 men. 

On the Hungarian side, John Hunyadi led the defense of the city. 
The siege began in earnest on July 4 when the Ottoman cannons started bombarding the walls. 

The most intense fighting happened during a massive Ottoman assault on July 21. This attack began at sundown and continued throughout the night.

While the struggle between the Ottoman Empire and European powers continued for centuries, the successful defense of Belgrade boosted European morale and protected the kingdom's southern gate.
