As in the previous Austrian offensive, the return of the Ottomans forced the Habsburgs in Austria to go on the defensive. In 1532 Suleiman sent a massive Ottoman army to take Vienna. However, the army took a different route to Kőszeg. After a defence by a mere 700-strong force led by the Croatian earl Nikola Jurišić, the defenders accepted an "honorable" surrender of the fortress in return for their safety. The Sultan then withdrew, content with his success and recognizing the limited Austrian gains in Hungary, while forcing Ferdinand to recognize John Szapolyai as King of Hungary.
