content: Invaders shouldn't mess with Polish People, they might forget about Battle of Vienna:  Title Here  The battle was won by the combined forces of the Holy Roman Empire of the German Nation and the Polish–Lithuanian Commonwealth, the latter represented only by the forces of the Crown of the Kingdom of Poland (the march of the Lithuanian army was delayed, and they reached Vienna after it had been relieved).[19] The Viennese garrison was led by Ernst Rüdiger Graf von Starhemberg, an Austrian subject of Holy Roman Emperor Leopold I. The overall command was held by the senior leader, the King of Poland, John III Sobieski, who led the relief forces. The opposing military forces were those of the Ottoman Empire and Ottoman fiefdoms, commanded by Grand Vizier Merzifonlu Kara Mustafa Pasha. The Ottoman army numbered approximately 90,000[7] to 300,000[12][13][14][15][better source needed] men (according to documents on the order of battle found in Kara Mustafa's tent, initial strength at the start of the campaign was 170,000 men[11]). They began the siege on 14 July 1683. Ottoman forces consisted, among other units, of 60 ortas of Janissaries (12,000 men paper-strength) with an observation army of some 70,000[20] men watching the countryside. The decisive battle took place on 12 September, after the united relief army had arrived.
