The Polish Army actually saved all of Europe from a massive Islamic invasion in 1683. The Ottoman Empire was at its height, controlling much of the Middle East, North Africa, and a significant chuck of Europe. They sent an invasion Army of over 150,000 to split Europe in two. They quickly overran the Austrian defenses, and laid siege to the great city of Vienna.
The city was only saved from a Jihadist slaughter by the arrival of the entire Army of Poland, which included over 20,000 Calvary. They had marched all the way from Poland, to lift the siege of the city. The Winged Polish Hussar Calvary was perhaps the most feared fighting force in the world at that time. Here is a photo of how these Knights were equipped when they went into battle:
Here is a famous painting of the battle, showing the Winged Hussars crushing the Muslim forces of the Ottoman Sultan:
If it had not been for these brave Polish fighters, everyone in Europe today might now be Muslim.
