In the Battle of Tsushima on March 14, 1905, the Borodino-class battleships were subjected to the most severe test possible at that time - complete destruction by the entire power of concentrated artillery fire at the disposal of the Japanese fleet, in conditions that deprived the ships of the opportunity to actively counteract this destruction .Note. OCR: A significant part of the issue is the author’s assessment of the actions of Rozhdestvensky’s squadron both during the campaign and directly in Tsushima. Materials from the memories of direct participants in the events were used.
