One of the main events of the Crimean War of 1853–1856 was the heroic defense of Sevastopol, which lasted almost a year. 349 days—from September 13, 1854 to August 27, 1855—Russian soldiers and sailors, despite the numerical superiority of the enemy, held the city and displayed their heroism, courage, and valor in the fighting. All of it, with full historical accuracy, is told in his book by Sergey Timofeyevich Grigoriev.
