The event depicted happened in 1566 during the siege of Szigetvar in Hungary. The vast Ottoman army of over 100.000 men, led by sultan Suleiman The Magnificent was on their conquest of Vienna. On their way lay the fortress of Szigetvar with merely 3000 men and their commander, Croatian general Nikola Šubić Zrinski, the person sitting in front of you. The siege lasted for a month, and Turks suffered heavy losses. The sultan himself died, but the fact was kept secret so as not to shatter the troop’s morale.
On the day of the final battle, it was obvious that the walls wouldn't hold any longer, so the defenders, led by Zrinski himself, decided to go for the last heroic attack..The fortress was lost but, due to heavy casualties, the Ottoman advances were stopped and Vienna was never reached and thus saved. The heroes didn’t die in vain!
