After the bloody War of Independence (March 26, 1971 – December 16, 1971) Bangladesh experienced a crucial need to restore the work of the «sea gate» of the country - the port of Chittagong which waterways were mined and cluttered with submerged ships. Then the Soviet Union promptly responded to the request of the leader of the young republic Sheikh Mujibur Rahman to clear the port area and the navigable channel of the Karnaphuli River. To accomplish this task the Soviet Union’s Pacific Fleet naval expedition EON-12 was formed and sent to Bangladesh. From April 1972 to June 1974, Soviet sailors, divers, scaffolders worked uninterruptedly on the restoration of maritime navigation. Sailors successfully coped with the task in spite of the difficult climatic and living conditions. The government of Bangladesh praised the heroic work of the participants of the Soviet expedition, and Bangladesh leader Sheikh Mujibur Rahman said that their selfless work became the foundation of strong friendship between the two countries.
Unfortunately, not all sailors returned home. On July 13, 1973 Yuri Redkin, the senior sailor of the floating workshop of the PM-156 of the Kamchatka Flotilla, lost his life in the line of duty. He was buried with military honors on the territory of the Bangladesh Naval Academy in the place where the Carnaphuli River flows into the Bay of Bengal. Every year on the birthday of the sailor, on December 18, a solemn ceremony of laying wreaths on his grave takes place on the territory of the academy with participation of the Russian diplomats, academy leaders, representatives of the city administration and the public. In 2016 and 2017 the fellow sailor’s grave was visited by direct participants of that memorable operation, who arrived in Bangladesh at the invitation of the country's Prime Minister Sheikh Hasina.
