When Mehmed III came to throne while the Ottoman-Austrian wars were continuing and he immediately focused on the Wallachia problem. In 1595, the Austrian Army besieged the Castle of Estergon. Mehmed Pasha did not assisted the castle although he and his army were 49 km. away from the region. As a result of this negligence, the castle surrendered after a very brave defence.

Sinan Pasha campaigned to Wallachia ruled by Prince Mihai Vitezul. The Ottoman forces invaded Bucharest and Tergoviste. But, Mihai attacked after a while and the Ottoman forces retreated. Many soldiers had died.

Following the fall of the Estergon Castle, Visegrad was occupied by the Austiran forces. The yeniceris reacted against the loss of these important castles, and towns and they forced the sultan for another campaign.
