"The unrelenting siege began on 9 August and the defenders, reduced to just 600, were forced into the keep. After waiting in vain for relief from the imperial army positioned in Győr to defend Vienna and a persistent drought that dried up the marshes and the moat, on 8 September 1566 Zrínyi and his remaining force of 300 sallied forth from the blazing fortress. He was captured and beheaded by the Turks.

The first day cover features Zrínyi’s coat of arms and the siege of Szigetvár in 1566 based on a con-temporary engraving. The postmark shows the hero’s helmet, club and sword in a stylised form. "
