Question: Question: How old was Evrenos Beg when he first fought Pedro's forces at Leontari? Passage:On 6 September that year, Pope Urban VI declared that as James of Baux's successors had forfeited their rights to the Holy See, the principality belonged to him and he devolved its government on Paul Foscari, the archbishop of Patras, who in turn made Pedro vicar general. Pedro was constantly at war with the Despotate of Morea, against whom he even used Ottoman pirates, and the Duchy of Athens under Nerio I Acciaioli. The latter was captured near Vostitsa on 10 September 1389 while trying to sit to talks with Pedro concerning Argos and Nauplia. He had to buy his freedom with concessions to the Navarrese ally, Venice. Late in 1394 or early in 1395, the Turkish general Evrenos Beg invaded the despotate and met Pedro's forces at Leontari. Together the two besieged and took Akova (28 February). After Evrenos returned to Thessaly, Pedro was defeated by the Greeks and taken captive with the grand constable Andronico Asano Zaccaria, his brother-in-law. In December, Venice paid 50,000 hyperpers for the release of her allies.
