Question: Which novel was the opera at which Artyom Melikhov has his first appearance based?
Sentence (from "War and Peace (opera)"): Although Tolstoy's work is classified as a novel, the 1812 invasion of Russia by the French was based on real-life events, and some real-life people appear as characters in both the novel and the opera, e.g. Prince Mikhail Kutuzov and Napoleon Bonaparte.
Relevant evidence: No
