The correct answer is: Sevastopol Sketches.

Explanation:

Sevastopol Sketches was Leo Tolstoy's book of fiction which describes his time serving in the Crimean war. It contains three short stories published in 1855 to describe his experience during the Siege of Sevastopol (1854-1855). The name originates from Sevastopol, a city in Crimea where Tolstoy and his military unit were located during the siege.  

Names of the stories are: Sevastopol in December, Sevastopol in May and Sevastopol in August .

In these stories Tolstoy examines the senselessness and vanity of war, describes enemies, examines psychological aspects of war, and describes the eventual defeat of the Russian forces.

These stories formed the basis of many of the episodes in Tolstoy's novel War and Peace.
