The siege was badly managed and several attacks failed with very high numbers of casualties on the Habsburg side.

The Ottomans then occupied the city, which in its turn was celebrating the liberation, with a trick: Suleiman the Magnificent invited the infant John II Sigismund Zápolya with the Hungarian noblemen into his tent, meanwhile the Turkish troops began to slowly infiltrate into the fort as "tourists" seemingly in admiration of the architecture of the buildings.

All of them were allowed to leave with one exception: Bálint Török, whom Suleyman considered a possible powerful opponent.

The Royal Court, the noblemen, and citizens of Buda were allowed to leave the city with their possessions unharmed.

[6] The victory allowed the occupation of central Hungary by the Ottomans for around 150 years, and is therefore comparable in importance to the Battle of Mohács in 1526.
