Stephen, while Vlad is imprisoned in Hungary in 1465, again advances towards Chilia with a large force and siege weapons, but instead of besieging the fortress, he shows the garrison, who favor the Polish king, a letter in which the King requires them to surrender the fortress.

The garrison complied with the King's demand and Stephen enterd the fortress escorted by Polish troops.

Mehmed is furious about the news and claims Chilia as being a part of Wallachia, which now is a vassal to the Porte, and demands Stephen relinquish ownership.

However, Stephen refuses and recruits an army, forcing Mehmed, who is not yet ready to wage war, to accept the situation, if only for the time being.
