Azov campaigns (1695–1696)

The Azov campaigns of 1695–1696 (, "Azovskiye Pokhody"), were two Russian military campaigns during the Russo-Turkish War of 1686–1700, led by Peter the Great and aimed at capturing the Turkish fortress of Azov (garrison - 7,000 men) with the aim of controlling the southern mouth of the Don River gaining access to the Sea of Azov and entrance to the Black Sea. Despite stubborn resistance and heavy casualties, the Russians under General Sheremetev after a failed siege in 1695 managed to capture the fort, accompanied by a naval force, in July 1696, marking the first major Russian victory against the Turks.
The first Azov campaign.
The first Azov campaign began in the spring of 1695. Peter the Great ordered his army (31,000 men and 170 guns) to advance towards Azov. The army comprised crack regiments and the Don Cossacks and was divided into three units under the command of Franz Lefort, Patrick Gordon and Avtonom Golovin. Supplies were shipped down the Don from Voronezh.
In 1693 the Ottoman garrison of the fortress was 3,656, of whom 2,272 were Janissaries.
Between June 27-July 5 the Russians blocked Azov from land but could not control the river and prevent resupply. After two unsuccessful attacks on August 5 and September 25, the siege was lifted on October 1.
Another Russian army (120,000 men, mostly cavalry, Streltsy, Ukrainian Cossacks and Kalmyks) under the command of Boris Sheremetev set out for the lower reaches of the Dnieper to take the Ottoman forts there. The main fort at Gazi-Kerman was taken when its powder magazine blew up, as well as Islam-Kerman, Tagan and Tavan, but the Russians were not able to hold the area and withdrew most of their forces. By the Treaty of Constantinople (1700) the remaining Russians were withdrawn and the lower Dnieper was declared a demilitarized zone.
The second Azov campaign.
At the end of 1695 the Russians began preparing for the second Azov campaign. By the spring of 1696 they had built a fleet of ships to block Turkish reinforcements for the garrison. The cavalry under the command of Sheremetev (up to 70,000 men) was once again sent to the lower reaches of the Dnieper. From April 23–26 the main forces (75,000 men) under the command of Aleksei Shein started to advance towards Azov by land and water (the rivers of Voronezh and Don). Peter I and his galley fleet left for Azov on May 3. On May 27 the Russian fleet (two ships-of-the-line, four fire ships, 23 galleys and miscellaneous vessels, built at Voronezh and nearby locations) under the command of Lefort reached the sea and blocked Azov. On June 14 the Turkish fleet (23 ships with 4,000 men) appeared at the mouth of the Don. However, it left after having lost two ships in combat. After massive bombardment from land and sea and seizure of the external rampart of the fortress by the Ukrainian and Don Cossacks on July 17, the Azov garrison surrendered on July 19.
Aftermath.
The Azov campaigns demonstrated the significance of having a fleet and marked the beginning of Russia's becoming a maritime power. Russia's success at Azov strengthened its positions during the Karlowitz Congress of 1698–1699 and favored the signing of the Treaty of Constantinople in 1700.
As Azov's harbor was not convenient for the military fleet, the Tsar selected another more appropriate site on July 27, 1696, on the cape Tagan-Rog (Taganrog). On September 12, 1698, Taganrog was founded there, which became the first military base of the Russian Navy.
Although the campaign was a success, it was evident to Peter I of Russia that he achieved only partial results, since his fleet was bottled up in the Sea of Azov due to Crimean and Ottoman control of the Strait of Kerch. A regular navy and specialists who could build and navigate military ships were necessary for resisting the Ottoman attacks. On October 20, 1696, the Boyar Duma decreed the creation of the regular Imperial Russian Navy; this date is considered to be the birthdate of the Russian Navy. The first shipbuilding program consisted of 52 vessels.
In 1697, a Russian ambassador present at the Safavid court raised an issue by handing over a note which stipulated that "Lezgi, Circassian, and other Caucasian tribesmen, ostensibly Persian subjects", had provided assistance to the Ottomans during the Azov campaigns. The report also included the request to declare war on the Ottomans, as well as to repay some 300,000 tomans to the Russians, which the report asserted were owed to the Tsar "since the days of shah Safi" (r. 1629–1642).
