The siege of Taganrog is a name given in some Russian histories to Anglo-French naval operations in the Sea of Azov between June and November 1855 during the Crimean War. British and French forces were implementing a strategy of destroying the supply lines for the main Russian army which ran through the Sea of Azov. Taganrog was one of the major logistical hubs of the Russian army and was attacked and its military depot destroyed on 3 June 1855 as part of a series of attacks on all major Russian supply bases in the area, except Rostov-on-Don, which could not be reached due to the large shoals not admitting any available warship.
