How did Mikhail Lermontov’s death resemble Aleksandr Pushkin’s death?

Mikhail Lermontov’s death resembled that of Aleksandr Pushkin in that both poets died as a result of fatal duels.12

Pushkin was mortally wounded in 1837 while defending his wife’s honor against influential enemies. Lermontov, who was deeply affected by Pushkin's death and famously denounced the court aristocracy for their role in that tragedy, met a similar fate four years later. In 1841, while staying in the health resort city of Pyatigorsk, Lermontov became embroiled in an atmosphere of intrigue and scandal. A quarrel was provoked between him and an officer named N.S. Martynov, which culminated in a duel that ended in Lermontov's death.312
