Zinaida Arkhipovna Krakova, Senior Sergeant of the Medical Service, served as a nurse in the mobile field hospital No. 4187. She was born in Tsaritsyn in 1910. At the beginning of the war, she worked as a telegraph operator in Stalingrad. In 1942, she was drafted into the army but was unable to proceed to the front due to illness. Zinaida was promoted to the position of senior operating nurse at the hospital, located in her native city of Stalingrad. Following the commencement of aerial bombardment on 23 August 1942 and the ensuing battles in the immediate vicinity, she assisted in the evacuation of the wounded. The hospital was evacuated to Leninsk, where she was on duty in the sorting department. Subsequently, a portion of the hospital was relocated to Ostrov Zelonyy (Zelonyy island), situated in proximity to the Tractor Plant. There, they provided medical care to soldiers who had sustained injuries during the Battle of Stalingrad.

Once the conflict on the Volga had come to a conclusion, the medical facility where Zinaida Krakova was employed relocated in accordance with the advancing military forces, thereby becoming a mobile unit.

During the Battle of Kharkov in 1943, Zinaida Krakova was transferred to another mobile hospital, which was designated the number 5249. Her daughter Lira, who was 11 years of age in 1942, accompanied her on all her journeys. She was even admitted to the hospital staff. Together with the hospital, Zinaida Krakova traversed Ukraine, Poland, and ultimately reached Germany.
