The Cossacks [he said], a free people, placed themselves under the Poles, but being unable to endure Polish oppression any longer, they have sought protection elsewhere, and they are now under the Turkish banner. If the inhabitants of an oppressed country, in order to obtain deliverance, implore the aid of a mighty emperor, is it prudent to pursue them in such an asylum? When the most mighty and most glorious of all emperors is seen to deliver and succour from their enemies those who are oppressed, and who ask him for protection, a wise man will know on which side the blame of breaking peace ought to rest. If, in order to quench the fire of discord, negotiation is wished for, so let it be. But if the solution of differences is referred to that keen and decisive judge called ‘the Sword,’ the issue of the strife must be pronounced by God, by whose aid Islam has for a thousand years triumphed over its foes.[26] In the campaign of 1672, the important city of Kaminiec, the capital of Podolia, was captured. The King of Poland then sued for peace, and the treaty of Bucsacs was agreed to, under which the province of Podolia was ceded to the Sultan. The treaty, however, was disavowed by Sobieski and the principal nobles of Poland. They renewed the war against the Turks. It lasted for four years. In 1673 the Turkish army, under Ahmed Kiuprili, met with a crushing defeat from the Poles, under Sobieski, near Choczim. His camp was surprised. The Wallachians and Moldavians deserted him on the field and went over to the enemy. There was great slaughter of the Turks. In the following year the Turks returned to the charge, but were again worsted. In 1675 Sobieski, aided by the Russians, gained another great victory over the Turks at Lemberg. But in the following year the Turks, under the command of Ibrahim Pasha, turned the tables on the Poles. The superior resources of the Turks, under the able administration of Kiuprili, told at last in their favour. Sobieski, who had become King of Poland, was defeated. The whole of Podolia fell into the hands of the Ottomans. Sobieski was now willing to come to terms. Under the treaty of Zurawna (October 27, 1676) terms rather more favourable than those under the repudiated treaty of Bucsacs were conceded to the Ottomans. Podolia was ceded to them.
