Relations between the Turkish Empire, Zaporozhian Cossacks and Crimean Khanate in the first half of the XVII century

The emergence of the Cossacks on the stage of history began, when Ukraine entered Poland's domination. Late Mr. Pritsak mentioned at lenghth, that the culture and civilisation of the Kievan Rus kept its progress under the authority of the Golden Horde [32, pp. 1-28]. The recent histories, too are in the same direction on the Ukrainians' entering into the course of assimilation under the domination of Poland. This course of assimilation was carried by the Shlachta in the social, economic and cultural fields [20].

Towards 1520, the Crimean Khanate had reached the peak of its strength, had ascendancy over Moscow, and intensified its pressure over the Kievan Area under the domination of Poland. At this period, the Shlachta put into action some military units it had picked up among the Ukrainian population. This stage is important in view of its constituting the beginning of the course, when the Cossacks were employed as the border guards against the Ottomans and Crimeans. Those border forces under the authority of the Shlachta were protecting the Ukrainian border population on one hand, and it also could carry on some offensive actions on the other hand. These forces gave a politic and military function to the population of the middle and lower Dniepro region by integrating them with the Cossacks. Thus, a new era began, during which the Cossacks also represented opposition to the Polish Shlachta, apart from their main task of protecting the Polish population against the Crimeans [28, pp. 243-258].

The most interesting and important personality in that period was undoubtedly Dimitry Vishnevetsky. The population living in the field stretching from the north of the Middle Dniepro Area to the Lower Dniepro Area resisted the domination of the Shlachta. This resistance was an inactive displeasure in the first stages. Dimitry Vishnevetsky belonging to the Shlachta himself, discerned this social resistance consisting mostly of the Ukrainian population and attempted to use it in favour of reaching his own politic aim. In fact, Vishnevetsky was a Polish nobleman having fallen in conflict with the Polish rulers, because of some land problems. This person that was one of the highest Polish nobles, and he tried to create a new principality in the area spreading from Kiev to the Lower Dniepro Area under the vassalage of any great power except for Poland. The most proper alternative as a suzerain was the Ottoman Empire. Vishnevetsky attempted to actualize his aim through a visit to istanbul.

We don't know what he did, by who he spoke to, in what sort of negotiations he engaged, which proposals he offered, what sort of answers he got; but from the evolution of the events we understand that he couldn't get a positive reaction from the Ottoman administration. The conjuncture in 1550s was not favorable for the attempt of Vishnevetsky. The Ottoman Empire concentrating its force in the west upon Austria, and in the east upon Iran, was in peace with Poland. The classical Ottoman - Polish amity starting at the time of Suleyman the Magnificent will last for until the end of the XVIth century. Vishnevetsky turned to Moscow when he couldn't take a desired answer from istanbul. A rival in extreme cost to Poland and Ottoman without any risk was irrefusable for Moscow. Vishnevetsky continued his actions with the assistance provided to him by Ivan IV. The Ottomans witnessed to the pressure from Vishnevetsky in the decade of 1550-60. Ivan IV did not have enough power to protect Vishnevetsky against Poland and the Ottomans. In that period, the Ottoman-Moscow classic friendship was valid too. Vishnevetsky having failed to get his aims, took part in the rebellion of Moldavia launched and headed by Albert Lasky in the 1660s. His aim in that attempt, too was probably to replace Moldavia's Hospodar and to build a new vassal state according to the conditions of the period. He was caught, brought to Istanbul and executed. Though the action of Vishnevetsky started with the Cossacks along the Danube and Dniepro water basins did not bring him success but it evoked the longstanding echoes. Vishnevetsky accomplished his successful fights by organising the Cossacks' communities in the Danube and Dniepro water basins against the Ottomans that was the superpower of the age. The Hortytsia Base which was the centre of the free Cossacks was claimed to be have been founded by him [27, pp. 95140; 29, pp. 55-95; 34, pp. 258-279; 35, pp. 261-275].

The Cossacks rising to the level of strong border forces owing to Vishnevetsky grew stronger and stronger due to supporting by some strata of the population in the resistance of the latter one to Poland, the Crimea and Moscow. While the Porogs were turning into the land of the Free Cossacks, the Ukrainian enslaved population was integrated with the Registered Cossacks under the control of Poland. Poland became depended on the Cossacks in the said time. The Cossacks became the most important professional forces of the 16th century. Poland made use of the Cossacks against Moscow in the north, and against the Crimea in the south. As for the free Cossacks are concerned, they turned the Black Sea into a frightening battlefield by dashing onto the Ottoman-Crimean bases according to their strategic purposes.

3. Cooperation between the Cossacks and the Crimeans for a Joint Purpose

The Cossacks got the power enough to permit them to move free after 1580s. During this period, the Ottomans showed serious weaknesses against Austria; the fact that Wallachia and Bogdan played an important role in this weaknesses was to some extent related to the Cossacks. The Ottoman Empire increased taxation in parallel with an increase of the expeditionary expenses, and imposed additional dues they couldn't overcome on those principalities, who were obliged to meet the requirements for provision and transportation of the army on these expeditions. The other factors that increased the mentioned problems were weakening of the Ottoman Empire and loss of influence on the environment. Since the factors like these the population of Wallachia and Moldavia was coming to the edge of the crisis [8, p. 615].

In this case, the Cossacks, who were international powers, attacked Azak and caused great damage. After the attacks that caused great panic and echo in Istanbul, the Ottomans started to watch regularly the Cossacks and took necessary precautions in line with the information they obtained (For the Cossack attacks to Azov, see: Decree to Caffa Governor, dated 23 Cemaziyelahir 990 / July the 15th, 1582, BOA, MD, XLVII, 214/503 [2]; Decree to Captain Pasha, dated 26 Cemaziyelahir 990 / July the 18th, 1582, BOA, MD, XLVII, 219/516 [3]; Decree to Mehmed Bey who was the former Caffa Governor, dated 26 Safer 991 / March 21st, 1583, BOA, MD, XLIV, 171/352 [4]). The development of the Cossacks in this way continued. We shall not elaborate all of the corrponding events, but we do not want to bypass one of them. The Cossacks wanted to be recognized as a legitimate force by the ambassador of the Crimean Khanate. Yevornitsky mentions that the Crimean Khan Islam Giray responded in the affirmative to this demand [40, p. 62]. The death of Stephan Batory (1586) became the turning point. The plan to put the Cossacks under the control of Rada grew weaker after this date. The Szlachta did not not yet have any national purpose, and moved upon its own economic interests. As long as the institutional identity of the Cossacks were developing, the tendency of the Ukrainian peasantry to them increased. Thus, the Ukrainian peasants turned to the Cossacks as a hope to get independence against the oppressions of Szlachta [9, p. 97]. Poland comprehending that the Cossacks entered into the coarse of independence made some regulations in 1590 restricting significantly their rights and undertaking some measures intended for putting the Cossacks under severe control [13, p. 181].

The more Poland was increasing its pressure upon the peasants, the more the relations between the peasants and Cossacks were developing. The Ukrainian society reached to the state of rebelling against the Szlachta in the 1590s. The rebellion headed by Kozinsky was the first one. Kozinsky taking refuge to the Cossacks by escaping from the economic conflicts among the Szlachta was appointed as Ko Ataman (1590), and headed for rebellion to take back what he had lost by the defeat in 1592. The Cossacks under the command of Kozinsky were beaten in the first battle in 1593, but won the second. Kozinsky, who soon won great success and became the leader of Ukraine, acted to seize Kiev in the final stage. Although Kozinsky was killed in this siege the Cossacks continued to the invasion. Poland could get out of this invasion with the support of the Crimean Khanate. As the Crimean troops attacked to the Sich, Zaporozhian Cossacks returned home by ending the siege. This siege of Crimean probably had taken place in cooperation with Poland [9, p. 105; 28, pp. 326].

By this time the Cossack Community had become a social and politic power. The social component of this power in the state constituted an attractive ambiance for the losers in the warfares among the Szlachta. The ones offended by Poland, tried to experience their chances by taking a refuge among the population consisting mostly of the Ukrainian peasants. Thus, Naliveko, emerging after Kozinsky pursued the same way. Naliveko, a member of the Szlachta, headed the Cossackdom by moving his own forces, and entered into a cooperation with the Zaporozhian Cossacks. Naliveko rebellion breaking out in 1594 continued succesfully in 1595. He demanded to be handed over the line between the Dniepro and Bratislava to the Cossacks in return for an agreement with Poland. The Polish government appointed a high-level General Zolkievsky over Naliveko. In the end of strong struggles continuing until 1597 the Rebellion was suppressed [28, pp. 327-334]. Poland managed to suppress the said uprisings with great loses. After crushing the Zaporozhian Cossacks using an unproportional force, the charge to control them was assigned to the Registered Cossacks. Poland empowered the Registered Cossacks for this mission and settled them near the Zaporozhian base

Hortytsia. The Zaporozhian Cossacks being immovable fell into a great crisis [9, p. 148].

The Cossacks crisis ended with Samuel Koska becoming the Ataman in 1599. This veteran revived the Cossacks again. Poland was obliged to support the Cossacks in their struggling in Wallachian and Moldavian problems, Livonia Wars and against Moscow. In spite of all its disadvantages, Polish General Zamoisky applied for being supported by the Cossacks. Samuel Koska turned this successfully into a politic advantage. He proceeded in bargain as a free side with Poland and negotiated his claims for his supporting. Koska imposed his conditions, and in this way a new Poland-Cossacks cooperation started. The Cossacks supported Poland in every field, and they moved unchecked along the southern borders, to the Crimea, Wallachia and Moldavia. During the period when the Turkish-Austrian Wars were continuing in the highest scale, and when Moscow was in troubles period, Poland, that eased its cooperation with the Cossacks, was taking advantage of the weak positions of its rivals. The Cossacks were unavoidable at this period for Poland. Ten thousands of Cossacks took part in Poland's wearing expedition launched against Moscow and returned home with lots of booty [6, p. 92].

After Poland had got through the troubles period, the Cossacks, as if being a half-free community, moved towards the Turkish-Crimean borders and made there terror. In the Black Sea there was no place that was not under the menace of Petro Konoshevich Sahaidachny, elected Kos Ataman in 1613. The Dniepro was exceeded, the Black Sea coasts, foremost Sinop, became the main targets of Cossacks' attacks. Those attacks reached the very harmful state, since "the converted slaves" had fled from the Ottoman Empire, the Cossacks informed. Na'yimв mentiones that the Sinop foray occured in cooperation with those converts [23, p. 118]. Cossacks' raids after Sinop foray continued in a high level. They could dare to attack the outskirts of Istanbul after foraying Caffa and Trabizond in 1615 [40, p. 148]. At that time Poland, and especially the Szlachta, were in the mood of approaching adversely the classical status of the Ottoman Empire. Poland now intervened to Moldavia, and protected the politic sides opposite the Ottomans.

There was not avoided fighting with the Ottomans at the said point. It is interesting that this new mood was developed in parallell to the Cossacks' raids. The largest part of Poland's forces actually consisted of Cossacks. Pechevi designates those "Rus", and separates them from the Polish. According to the same source, in the war broke out the Moldavian problem since a half of the Poland's army consisted wholly of 40,000 soldiers who were Cossacks [31,p. 446]. The population Pechevi referred to "Rus" was not related with Moscow sphere. These represented the Ukrainian-Rus population. There were endeavors to spread into Transilvania the movement, which influenced Moldavia [18, p. 129]. Though the Cossacs were under control of the Szlachta, they moved further, when they found the new opportunity and performed their own plans. It can be said that this period was the golden age for the Cossacks. After the negotiations with Austria, the Ottoman administration took essential measures to solve the Moldavian problem, that reached the separation point. The Polish-Cossack army was put on a serious routeexpedition performed by the great army in 1616. The corresponding victory of the Ottomans increased the forays of Cossacks instead of reducing [28, pp. 348-350]. Following this Ottoman expedition, the Dniepro, Caffa, Sinop and Trabizond came under great attacks of the Cossacks [22, p. 64]. At this phase the Cossack movement turned into a great extent guerilla movement, and the Ottoman State became unable to defend its borders [18,p. 128]. When the Cossack forays extended towards Istanbul in 1617, the tension between the Ottomans and Polish almost turned into war. After the two sides took the position of war, peaceful negotiations were concluded, and peace was set up before a war outbroke. Although the main theme of the treaty was the Cossack attacks, the dimensions and effects of the attacks continued to increase after the agreement [1, pp. 7-8]. Finally, the famous Khotyn campaign (March - September 1621) commanded by the Turkish Sultan himself, was put in practice, it lasted for 4.5 months and failed. The main cause of the failure of this expedition was the Cossacks made the Turkish front back unsecured from continuous unexpected forays [22, p. 72].

There was another reason why the Turkish front back and the fighting power were weak. That was the Crimean inside crisis being in parallel to the Cossack fenomenon. The Ottomans used mostly not the Crimean cavalry, but the Nogays in this important expedition, because the Crimeans had degraded, while the Nogay Tatars had been ascended in importance beside the Porte at the period in question. The main reason for the said cardinal change was the Crimeans were trying to establish their vassalage towards Ottomans in another frame. But, the Ottoman central administration would not have been contented with an alteration of the ancient classic status; at this point the Ottoman-Crimean relations would have had a heavy blow, the Crimean tribal forces would have gone into new trends against the Ottomans, and this stage would have been ended in a blooded rebellion.

The problem that broke out between the Crimean Khanate and the Ottomans almost resembled the one between Poland and Cossacks. At the same time, a deep conflict emerged between the Ottomans and the Crimean tribal forces. The main reason for this conflict to descend to the 1580s was that the Ottoman central authorities dismissed Mehmet Giray II (1578-1584) and appointed Islam Giray II [10, p. 56; 26, p. 492; 33, p. 492; 38, p. 54]. Those dismissal and appointance caused tensions that set up beforehand in different ways between both the powers to the level of an uprising. Mehmet Giray's II sons Saadet Giray and Murat Giray resistance to the dismissal of their father proceeded to a cooperation with the Cossacks and withdrew to the steppes. Murad Giray took refugee to the Tsar, and Moscow-Crimean-Cossacks cooperation started immediately after this period. The above cooperation did not develop through the equality concept of both the powers, but it manifested in the context that Moscow holding the appraised princes used the advantages it gained. Moscow forced the Crimean Khanate to put pressure over Poland [12, pp. 12]. The tension created by the Crimean rebellious princes strengthened Moscow against the Ottoman Empire; taking over the leadership of the rebels by directing the Crimean military power over Poland, Moscow also gained an advantage over this important opponent. These events also show a development of the Cossack-Crimean cooperation through Moscowian protection.

During the reign of Khan Bora Gazi II Giray, who ascended the throne after Islam Giray's II death, the Crimean uprising ended, and the Ottoman-Crimean cooperation reached its peak again. The Crimean Khanate had penetration over Moscow and Poland [26, p. 493]. While Khan Bora Gazi II Giray was facing again the task of making the Khanate a regional power against Moscow and Poland, the Ottoman-Austria wars broke out. Under the circumstances, the Ottomans demanded that the Khanate would join it with all forces of the later one at the Austrian front. But the Khan's priority was the

Moscovian and Polish fronts. The conflict which arose as the consequence ended in dissmissal of Gazi II Giray (1596). The dismissal of the Khan who had established his penetration into the Crimea and Caffa created a general discontent, and the dismissed Khan resisted to this fait accompli. Thus, Bora Gazi Giray obtained the throne again by removing Fetih Giray having been appointed as the Khan. During the second period of his khanship, he improved the Khanate's relations with the Ottomans, but he managed to do that only by renouncing the priorities of the Khanate's foreign policy [26, p. 494].

Bora Gazi Giray's death in 1608 undermined again the new founded fragile balance. In accordance with the concensus having emerged in that period, the tribal forces of the Khanate consisting of the Shirins, Barins, Sucuts and Mansurs, appointed Toktamysh Giray to the throne without consulting the Ottomans. The Ottoman central government having found the enthroning contradiction in relation of the antecedent valid between both of the powers, refused approving. This appointment caused a new crisis for a short time period that was more serious, than the one in 1580. Two brothers from the Girays Dynasty, Mehmet and Shahin Girays, launched a rebellion using support from all the local tribal forces, and from all the Tatars and Cossacks over the steppes in general [10, p. 73; 26, p. 494; 28, p. 368; 36, p. 39; 38, p. 24].

In spite of the fact that formally Selamet Giray was the Khan, the sovereignty was actually passed to Mehmet and Shahin Girays. According to the Ottoman historian Rydvan Pashazade, who was better, than other historians, aware of the time when his father was the Caffa Governor, the sovereignty of the Kipchak Steppe has been passed into the hands of both of the brothers since 1608 [36, pp. 4041]. There is information that the rebel princes made some preparations to attack and get the throne at the end of the last phase of Selamet Giray's reign [36, p. 21].

As it has been mentioned above, along this rebellion carried out in cooperation with the communities in the steppes, like mainly the Cossacks, Circassians and others, the Polish and Moscow's authorities replaced the Ottoman authority in the region. Penetrations of Moscow and Poland were actually temporary elements the Cossacks and Crimeans had brought into the region to break the Ottoman penetration. It is a very well known phenomenon how the Cossacks and Crimeans resisted Poland and Moscow according to the conjuncture. Those developments in the period, during which the Cossacks and Crimeans gained partially an autonomous status, also mark emerging of a new geopolitics in the Northern Black Sea. Roughly, the main character of the new conjuncture beginning in the first quarter of the 17th century was, that the border communities took control in the Northern Black Sea Area, and the the big powers lost their authorities over the larger border areas.

After the death of Selamet Giray, whose reign could not go beyond the formal frame, Chanibek II was appointed to the throne by the Ottoman central authority (1610). He encountered with a decided resistance of Mehmet and Shakhin Girays. If Rydvan Pashazade's information is taken into consideration, the formal appointment of the new Khan did not have any importance, because the rebellious brothers took under their control the Crimean capital Bakhchisarai and seized the rule by attacking from the very beginning. Thus, Mehmet Giray had become the Khan, and he appointed Shakhin Giray the Kalgai. The formal Khan Chanibek Giray II had taken refuge to Rydvan Pasha, the Ottoman governor in Caffa. According to the information given by Ridvan Pasha, the rebels proclaimed with the letters they wrote to him that they had effectively taken over the dominance and demanded recognition by the Ottoman government [36, p. 42]. Rydvan Pasha spoke to the pretenders that claiming for the throne in this way could not be legal, but they informed that they would make him approve by the sword, if he did not accept the situation [36, p. 43]. The Ottoman historians of the time mentioned that the fait accopmli of the two brothers was accepted by the Ottoman government [23, p. 102]. But, according to Rydvan Pashazade, in the case of such a heavy rebellion against the legitimate authority, Rydvan Pasha submitted an offer to the Ottoman government suggesting the fait accompli to be approved, and the government being about to send the certificate of the renunciation. Thus, the khanship though to be given to the Mehmet Giray, was given to Chanibek Giray. Rydvan Pasha who was appointed as the commander-inchief, was sent to enthrone Chanibek [36, pp. 47-48].

At this stage, the Ottoman ruling in the Crimea was ended, since both of the brothers respected the status of the Tatars [17, p. 351]. According to Rydvan Pashazade, the mainstay of Rydvan Pasha, who moved to appoint Chanibek Giray to the throne of the Crimea again and made the first battle in 1610, was heavy cannons. There were 4,000 janissaries and 5,000 cavalries at his disposal. As for Chanibek Giray's forces, they consisted only of a small unit of 100 soldiers. The main Crimean cavalries, Tatar mirzas, the heroes of Circassians, the Nogay combatants, soldiers of Jagataians were wholy in favour of Mehmet Giray.

Thus, Chanibek Giray and his protector the Ottoman Empire were in the situation of losing the Crimean population's support. Despite the fact that the rebellious Crimean forces were quite superior in number, Rydvan Pasha won the first battle. The Tatar cavalries approaching the shut of the scorching Ottoman cannonade were exterminated. Mehmet and Shakhin Girays fled. Our source Rydvan Pashazade tells that Mehmet Giray took refuge to Moscow, and Shakhin Giray did that to Iran. The rebellious brothers tried their chance once again by gathering forces from the steppes, but they were defeated in the second attempt, either [36, pp. 48-52].

The Crimean rebellion got a different extent at this stage, let alone decreasing. When Mehmed and Shahin Girays' later activities are taken into accounts, it is understood that they and their supporters actually went into a serious cooperation with the Zaporozhian Cossacks. The Ottoman sources report that Mehmet Giray was forgiven after the petition of pardoning, but he was exiled to Rhodes in the final phase. While Shahin Giray's flight continued, Mehmet Giray lived in exile in Rhodes between 1613 and 1623. The Khotyn Expedition's conjuncture made necessary dismissal of Chanibek Giray. Chanibek Khan, whose any serious function was not seen in the failed Khotyn expedition, having serious effects in the horribble end of Sultan Osman II, was dismissed, and Mehmet Giray was appointed as the Khan. Shahin Giray was appointed as the Kalgai, too [17, p. 35; 24, p. 35].

The fact that the Ottoman central government had to assign one of the two great rebels to the Crimean khansip and the second to the kalgaiship, the second place after the khanate, reveals how lame the Ottomans were. The Ottomans paid the cost of being deprived of the support of the Crimean forces by losing the Khotyn Battle. The Crimeans ended their alliance with the Ottomans against Poland, Moscow and the Cossacks, but they came to the point of making alliance with any power against the Ottomans after 1608. The tribal forces amalgated around the rebellious princes. In the population, subject to the Crimea and the hinterland, those who obeyed the ttomans were only Nogay Tatars. While the task of shooting back the rival forces were at the command of the Crimean Khans, who had been the leader of the Crimean tribal forces since the beginning, this task was carried out by Kantemir Mirza, the leader of the Nogay tribes during the Khotyn campaign, and this led the Nogaytribe organisation replacing the Crimean tribal forces, especially the Shirins - the most prestigious tribe in the Ottoman's northern policy. That Kantemir Mirza had a priviliged status belonging to the Shirins since the earlier times by seizing the opportunity the Crimean rebellion provided for him, made the rebellion rise to a different stage. As it was mentioned above, there was an indirect consensus among the Ottoman and Karachi Princes upon the Principal of the Shirins being higher than the other Princes.

During the Khotyn expedition, the Nogays removed the Shirins from their predominant position in the Ottoman political and military organisation, and replaced them by taking their place. When the Crimean tribal forces ended their traditional alliances with the Ottomans, the Ottomans replaced them by the Nogays. This can be considered as a natural development on the one hand, and as the Ottomans' carrying this natural course into policy, on the other hand. But, in fact, it was impossible that the balance could be assured by the Nogays, and the appointment of Mehmet and Shahin Girays was intended for the balance could be founded again. It is understood, that the Ottomans could not hold the Crimea, unless they founded once again the balance between the Nogays and the other tribal union. The Cossack raids in 1622-1623 climbed its peak, but it is seen, that they were only directed towards the coastal segments under the Ottoman control. There are serious indications about the Cossack raids reaching till Istanbul were planned in coordination with the Crimean rebellious princes [28, p. 377].

As all the sources have indicated in the alliance, Mehmet Giray set out to a great punishment of the rivals after enthroning in 1623. The main target in this punishment was the Nogays under the command of Kantemir. It was certainly contrary to the traditional status quo that the appointing of Kantemir by the Ottomans in the governorship status was targeted. Mehmet Giray from the very beginning moved contrary to the vassalage status of the Crimean Khanate, and orientated on gaining the complete independence. The great war between Mehmet Giray and Kantemir turned to a civil war. The Ottomans, having decided to protect Kantemir, appointed once again Chanibek Giray and dismissed the former Khan (1623) under the supervision of Rejep Pasha [36, pp. 60-61]. At that stage, Mehmet Giray was continuing to use full support from the tribal forces. Rydvan Pashazade thinks that, Rydvan Pasha, who was charged to enthrone Chanibek Giray, could not appreciate this fact, and trusted the authority only [36, p. 61]. Katip Chelebi confirms the claims, too [17, p. 56].

At this stage, the Crimean rebellious movement was not only against the Ottomans. There was a considerable amount of the Zaporozhian Cossacks in the company of the Crimean Rebellious forces. The war between the Ottomans under the command of Rejep Pasha and the Crimean-Cossacks alliance lasted for months. Caffa was destroyed to a great extent in the battles, where both sides incurred great losses. The Ottoman siege failed, and the khanship of Mehmet Giray was confirmed [39, p. 156].

In defeating the Ottoman forces the role of the Cossacks was greater, than the one of the Crimeans [22, p. 72]. The fire arms constituting the most important weakness of the Crimeans had been provided and used by the Cossacks. In these events, Iran, too, was apparently playing a role indirectly. It seems that there was an alliance between the Crimean-Cossacks allied forces and Iran against the Ottomans [24, p. 69]. A detailed study is needed to understand how large was the scale of the alliance with Iran. After the Ottoman fleet had withdrew, the Cossack attacks reached Yenikцy, a town near Istanbul. It was felt that some precautions had been made by drawing chains to both ends of the Bosphorus or by setting the ships side by side. The Cossacks raids reached quickly Sinop and Trabizond. The role of Ataman Safran who had been a captive for a long time in Istanbul was great [28, p. 383].

Maybe, the greatest sea battle the Black Sea has ever seen in its history occured in 1625 between the Cossacks fleet consisting of 300 chaikas and the Ottoman Empire. The Cossacks almost won the first phase of the batle, as there was no wind. The Cossacks chaikas did not need wind for moving, but the Turkish sailing ships could not move without wind. The battle carried out obviously by the Cossacks turned in favour of the Turks upon starting of the wind. This battle was lost by the Cossacks, the defeat was very serious, and it considerably affected both the situation of the Crimeans beside the Ottomans, and happened to be the fate for the Cossacks actions on the Black Sea [23, pp. 356-360].

After that defeat Poland and Cossacks lost the ascendancy, they had gained during their cooperation with the Crimean rebellious Princes against the Ottomans. On the other hand, after that defeat the Crimean-Cossacks alliance's dominance in the Crimea also entered a risky phase. Poland worried about the possibility for the Ottomans to launch counter attack. The Ottoman State took some measures to cut the Crimea's connection with the Cossacks in the the north before besieging the Crimea. For this purpose, a castle was built on the Dogan Passage on the Dniepro. The building of the castle was erected over Yilky Water, a branch of the Dniepro, to the north from the Cossacks base Hortytsa, and that shows how important the Cossack threat was [5, pp. 4/2, 5/4, 6/5, 19/25; 23, p. 398; 28, p. 387].
