We call it the Crimean War, the French - Eastern, the British - Russian. Someone even uses the term Zero World, and there is something in it, because the hostilities were not only in Crimea. Danube, Black Sea coast, Caucasus, Sea of Azov, Baltic, North, Petropavlovsk-Kamchatsky. In this war, one way or another, all the great powers of the 19th century participated, then for the first time a new generation weapon was used. The sail was replaced by steam, the tree by steel, the smooth trunk by rifled, the whipped horse by telegraph. A real military revolution, for which, first of all, people who have not yet mastered new opportunities were not ready. Isn't it the perfect time to send a twenty-first-century guest here?
