The Christians successfully defended themselves against the army under the command of Lala Mehmed during the siege, which took place between September 19 and October 13.

Naturally, in the fall of 1605, the Ottomans attempted to capture Esztergom, taking advantage of the current hardships facing the Habsburgs.

During the duration of the agreement, the Turks were not allowed to besiege any of Hungary's strengths, not even those held by Rudolph, but in addition to supporting Bocskay's armies, the Grand Vizier's main task would be to attack and occupy Austrian territories.
