History
The Siege of Belgrade began on the 4th of July, just like Constantinople, the  Ottomans hoped to make breaches in the walls large enough to let in Ottoman attackers. Belgrade was one of the best fortified positions in europe. The stout walls guarded three lines of defence,  with the inner part being the toughest part. The first few breaches were opened and on the night of 21st July, thousands of elite Janissaries forced their way through the breaches. Veteran troops held them off with furious attacks on the remaining outer walls. Hungarian and Serbian peasents who contributed attacked Ottoman camps. The Ottomans were so surprised by the assault that the remaining Janissaries were beaten back leading to a Hungarian and Serbian Victory. The battle stopped the Islamination of Europe and weakened the  Ottoman army.
