The Main Intelligence Directorate of the Soviet Union was in desperate need of information about the state of the strategically important airbase that had been taken over by the Luftwaffe.

To gain such intelligence for the Red Army, an underground reconnaissance organization was created by resistance members in Bryansk to infiltrate the airbase.

Morozova returned to Seshcha to work undercover at the airbase as a laundress, where she ended up meeting several of her friends from school that were unable to leave the city in time.

[1][2] In September 1943 Morozova left the partisan movement and joined the Red Army after Soviet forces retook control of Seshcha in the operation to retake Bryansk.

On 31 December 1944 after she was badly wounded in battle when a bullet shattered her wrist, she detonated a grenade on herself in order to avoid capture, ending her life and killing two SS soldiers.
