The next day the final battle was conducted. The castle of Szigetvár was burnt down to ruined walls by mining and burning huge heaps of woods put around it at all corners. In the morning, September the 7th, the all-out attack by the Turks began: fireballs, "Greek fire", concentrated cannonade, fusillade. Soon, the last Croat-Hungarian stronghold within Szigetvár was set ablaze. The entire Turkish army swarmed against the Old City, drumming and yelling, "..their flags darkening the skies.[cite this quote]" Reportedly, Zrinski prepared for the last charge, addressing his brothers-in-arms:
"..Let us go out from this burning place into the open and stand up to our enemies. Who dies - he will be with God. Who dies not - his name will be honoured. I will go first, and what I do, you do. And God is my witness - I will never leave you, my brothers and knights![cite this quote]"
The defender Zrinski wearing a silk robe, carrying a hanging golden key on his breast and wearing a hat with a crane aigrette, started an exit in force from the castle at the head of 600 of his troops. He was heavily wounded at his chest and his head by Ottoman bullets . Thus, at the end, the heroic obstinate commander, who survived a siege lasting 36 days, his dead body was beheaded by a sword lying on an Ottoman cannon . The Turks took the fort and effectively won the battle. Only seven defenders managed to get through Turkish lines.
