Stephen leads an incursion into Poland in 1459 in the search for Aron, but is met with resistance.

Instead, a treaty is signed between Moldavia and Poland, through which Stephen recognizes King Casimir IV Jagiellon as his suzerain, while Aron is barred from entering Moldavia.

He is forced to seek asylum in Transylvania.

Stephen’s objective is to regain the region of Budjak with the castles of Chilia and Cetatea Albă.

The region had previously belonged to Wallachia, but had been incorporated into Moldavia in the late fourteenth century.

Due to the decline of Moldavia during the civil war, the region had reverted to Wallachia, with Chilia being co-ruled by Hungary and Wallachia.
