On the initiative and financial support of Pope Innocent XI, the Holy Roman Emperor, the King of Poland and the Republic of Venice sent 80,000 troops into Buda, and Hungary.

The army was composed of Saxon, Bavarian, Brandenburg and Swedish troops, with lesser numbers of Italy, England, France and Spain, and some 15,000 Hungarians.

The city was well stocked with food, water and gunpowder, but only 8000 soldiers were garrisoned within; although the Ottomans had promised 50,000 troops, they had not yet arrived.

After more than 2 months of bombardment and a series of unsuccessful attacks, the city was reduced to ashes in the first days of September.

The memorial was erected in 1932 by the descendants of György Szabó, who was a Hungarian soldier of the liberating army and also fell on this spot on September 2.
