During the Crimean war, Balaklava served the British as headquarters. In Great Britain, the Battle of Balaklava is a well-known historical event. The expression thin red line has become habitual language use and stands for an extraordinary fighting spirit. Once, on 24th October 1854, the Times correspondent Russel observed how a superiority of Russian armed forces attacked the British troops stationed in Balaklava. Their commander, Sir Colin Campbell ordered his soldiers, who were wearing red tunics, to face the attackers in a line of defence and not to do a step back even if the losses were great. For the observing journalist this looked like a thin red line – hence the common expression. Literally as well as in transferred meaning the location of this theme is the supply channel. Starting at the entrance of the hangar and leading to the water channel, the supply channel is about 400 meters long and has rail facilities for moving transport carts.
