have the area belonging to Moldavia, as it would increase their commerce in the region. On 2 March 1462, in a renewed treaty between the two countries, it was agreed that no Moldavian territory should remain under foreign rulership, and if such territory was under foreign rulership, that territory should be regained. Later that year, it is believed that Stephen asked Vlad to return Chilia back to Moldavia – a demand which was most likely refused. On 22 June, when Vlad was fighting Mehmed, Stephen allied himself with the Sultan and with some Turkish assistance, he launched an attack on Chilia. The fortress, defended by tall stone walls and 12 cannons, was among the strongest fortifications along the Danube at that time. The Wallachians rushed to the scene with 7,000 men, and together with the Hungarian garrison battled the Moldavians and the Turks for eight days. They managed to defend the town, while wounding Stephen in his foot with shrapnel. In 1465, while Vlad was imprisoned in Hungary, Stephen again advanced towards Chilia with a large force and siege weapons; but instead of besieging the fortress, he showed the garrison – who favoured the Polish King – a letter in which the King required them to surrender the fortress. This they did, and Stephen entered the fortress where he found "its two captains, rather tipsy, for they have been to a wedding." Mehmed was furious about the news and claimed Chilia for being a part of Wallachia – which now was a vassal to the Porte – and demanded Stephen to give it over to him. The latter refused, however, and recruited an army, forcing Mehmed – who was not yet ready to wage war – to accept the situation, if only for the time being. The Moldavian prince, realising that a future war with Mehmed could not be avoided, tried to gain time by increasing his tribute to the Porte by 50 percent (to 3,000 ducats); and also sent an envoy to Constantinople with gifts for the sultan. In 1467, Matthias Corvinus of Hungary launched an expedition against Moldavia in order to punish Stephen for annexing the region. The invasion ended in a disaster for the Hungarians as they suffered a bitter defeat at the Battle of Baia, where Corvinus was thrice wounded by arrows and had to be "carried from the battlefield on a stretcher, to avoid him
