After graduating nursing courses Petrova entered the
Soviet Navy as a nurse in 1942. She was present in the Kerch-Eltigen operation in 1943 with the rest of the
Black Sea Fleet. On the night of 1 November she carried over twenty wounded soldiers from the battlefield in the night under the cover of darkness, running through a field of barbed wire and mines to reach numerous injured marines. For her bravery in the offensive she was awarded the title
Hero of the Soviet Union in November by decree of the Presidium of the Supreme Soviet. Less than a month after she received the award she was injured while holding back German soldiers in a series of following counterattacks in Eltigen on 3 December. She was taken to a hospital for her injuries but died the next day when the school building used as a hospital was bombed. Her remains were interred in the village of heroes in
Crimea. ==Recognition==
