to Russia as a result of the Russo-Turkish War (1828–1829) and the Treaty of Adrianople. To further protect the coast from Turkey, a coastal line of defense was built in 1830–1839 consisting of 17 fortresses. Several of these fortresses were founded in the suburbs of the modern Sochi, such as the fortress of Holy Spirit in Adler (1837), Lazarevskoye (1839) and Golovinskoe (1839). On 23 April 1838, the first stone of the fortress was laid in central Sochi, at the mouth of the Sochi River. This day coincided with the name day of Empress Alexandra Feodorovna, the wife of Tsar Nicholas I, and the fortress was named Alexandria after her. On 18 May 1838 it was renamed into Navaginsky, honoring the bravery of Navaginsky Regimen in the Russian–Circassian War. The construction was completed in July 1838. During the Crimean War of 1853–1856 it was abandoned and partly destroyed; it was rebuilt in 1864 under a new name Dakhovsky. The locals however did not recognize Russian rule and fiercely opposed what they perceived as genocide. Due to the ongoing Russo-Circassian War, the Russians could not establish full control over the land. This opposition attracted the interest of Britain, which was apparently selling weapons and ammunition to the Circassians. This caused a diplomatic conflict between the Russian Empire and Great Britain in 1836, centered on the Mission of the Vixen. The British ship Vixen loaded with weapons for the Circassians was captured and confiscated by the Russians at the port Sudzhuk-Kale (nowadays Novorossiysk). The British protested, but the position of Tsar Nicholas I was firm and a quick order was given to prepare the army for a war with Britain. In 1864, the Battle of Qbaada took place in 1864 between the Circassian army of 20,000 a Russian army of 100,000 men, consisting of Cossack and Russian horsemen, infantry and artillery. It resulted in Russian victory, and the Russian army began celebrating victory on the corpses, and a military-religious parade was held, as 100 Circassians were publicly mutilated in a public execution in order to establish authority. The Russian army then continued raiding and burning Circassian villages, destroying fields to prevent return, cutting down trees, and driving the people to the Black Sea coast. The end of the war was proclaimed on 2 June 1864 at Qbaada (modern Krasnaya Polyana) by the manifesto of Emperor Alexander II read aloud by the Grand
