Q: The Genoese held the colony of Galata on the Golden Horn across from the city of Constantinople since 1261 as part of the Treaty of Nymphaeum, a trade agreement between the Byzantines and Genoese. However, the dilapidated state of the Byzantine Empire following the civil war of 1341-1347 was easily shown in the control of custom duties through the strategic straights of the Bosphorus. Even though Constantinople was the Imperial seat of power with its cultural and military center on the shores of the Bosphorus, only thirteen percent of custom dues passing through the strait were going to the Empire. The remaining 87 percent was collected by the Genoese from their colony of Galata. Genoa collected 200,000 hyperpyra from annual custom revenues from Galata, while Constantinople collected a mere 30,000. The Byzantine navy, a notable force in the Aegean during the reign of Andronikos III Palaiologos, was completely destroyed during the civil war. Thrace, the main imperial possession besides the Despotate of the Morea, was still recovering following the destruction of marauding Turkish mercenaries during the civil war. Byzantine trade was ruined and there were few other financial reserves for the Empire other than the duties and tariffs from the Bosphorus.
What was the greatest income source of the Empire?

A: tariffs from the Bosphorus
P: At the end of March  Nakaznoy Hetman Ostap Gogol with the Podolian Regiment and some Budjak Tatars invaded the Letichevsky Powiat of the Podolian Voyevodstvo. Cossack-Tatar troops looted and burned the neighborhood of Bar, Medzebozh, Derazhnya, Old and New Senyavy, Zinkov and Gusyatin. On 20 July Doroshenko resumed the siege of the Polish garrison at Bila Tserkva and sent his younger brother Gregory and 2,000 Cossacks to Podolia. He sent the Kalnitsky regiment to Crimea to help Adil Giray against Zaporozhians. Doroshenko, with no more than 5,000-8,000 Cossacks  and 5,000-6,000 Tatar allies did not dare to go to war, but awaited Adil Giray before starting an offensive against Commonwealth. Most of the Budjak Mirzas who were with Gregory Doroshenko, on learning of the approach of the Polish militia, hastily left their ally and returned to their camps. Grand Crown Hetman Jan Sobieski advanced against Doroshenko and the Crimean horde. On 26 August at Bratslav the Polish army routed the Cossack and Tartar troops. The Poles defeated the Budjak Tatars and burst into Bratslav. The Cossacks took refuge in the city castle and the broken Tatars began to retreat in panic. Sobieski led cavalry in pursuit of the Tatars while some Poles stayed in Bratslav to besiege the castle. The Poles followed the Tatars to Batorg and completely defeated them. The Cossacks in the castle learned of the defeat of the Tatars and surrendered. Emir Ali, who commanded the Budjak troops said he lost 500 men. Despite the victory, Sobieski withdrew to Bar, where he arrived on 30 August.
