On 16 June the town of Esztergom was taken by storm by imperial troops in spite of its strong walls, after a gate was destroyed by cannons.

On 27 June the imperial army met a strong Turkish force of 17,000 men at the Battle of Vác under the command of Grand Vizier Kara İbrahim Pasha, who would eventually drive out the Habsburgs.

The imperial army of 34,000 men began the bombardment of Buda's fortress with 200 cannons on 14 July 1684, the anniversary of the beginning of the siege of Vienna.

Throughout July and August the imperial army made several attempts to attack the fortress, but all were repelled by the Turkish defenders.

At the beginning of September, an imperial general reported that the number of soldiers fit for service had shrunk to 12,500, and morale was low.

[5] Ironically, the blame for the failure was laid on the man who had only led the army at the beginning of the siege: Ernst Ruediger von Starhemberg.
