In the year 1683 the Ottomans started their second attempt to conquer Vienna, the seat of the Emperor of the Holy Roman Empire and the door to further conquest in Europe. It was a major effort with a huge army (170.000 men at the start of the campaign) - too much for the Emporer, who left the City before the Ottomans arrived. After an epic two months siege an allied relief army (Imperial and Polish troops) reached the outskirts of Vienna and in the final battle the Ottomans were decisively beaten and had to retreat the way they had come.
The moment depicted is when the Poles rush down from the hills on the western side of Vienna and the Ottomans (Jannisaries) try to stop them in no matter what environment - even in the vineyards, where place and visibility is very limited.
