Born in 1917 at Torbeyevo, Mikhail was the thirteenth child born to the family of a Mordovian peasant. In 1938 he graduated from a School of River Navigation (Речной Техникум) and worked as the captain of a small ship on the Volga. That same year he was conscripted into the Red Army and began education at a Chkalov Flying School, graduating in 1940.
Devyataev was an early entrant of World War II, destroying his first Ju-87 on 24 June 1941 just two days after Germany attacked the Soviet Union.
Soon he was awarded the Order of the Red Banner. On 23 September he was seriously wounded (he was hit into his left leg). After a long stay in the hospital he was assigned to slow-speed aviation (Night bomber Po-2) and then to medical aviation. He resumed his duties as a fighter pilot after his meeting with the famous Soviet ace Aleksandr Ivanovich Pokryshkin in May 1944. Commander of an echelon with the 104th Guardian Fighter Pilot Regiment (9th Guardian Fighter Pilot Division, 2nd Airforce Army, 1st Ukrainian Front), Senior Lieutenant Devyatayev destroyed 9 enemy planes.
On 13 July 1944 Devyataev was downed near Lwów over German-held territory and became a prisoner of war, held in the Łódź concentration camp. He made an attempt to escape on 13 August but was caught and transferred to the Sachsenhausen concentration camp. He soon realised his situation was perilous-as a Soviet pilot, he could expect extreme brutality; therefore, he managed to exchange identities with a dead Soviet infantryman.
With his new identity, Devyataev was later transferred to a camp in Usedom to be a part of a forced labor crew working for the German missile program on the island of Peenemünde.
Under hellish conditions, the prisoners were forced to repair runways and clear un-exploded bombs by hand. Security was rigidly enforced with vicious guards and dogs, and there was little chance of escape. Even so, by February 1945, Devyataev concluded that, however remote, the chance of escape was preferable to certain death as a prisoner.
Devyataev managed to convince three other prisoners (Sokolov, Krivonogov and Nemchenko) that he could fly them to freedom. They decided to run away at dinnertime, when most of the guards were in the dining room. Sokolov and Nemchenko were able to create a work gang from Soviet citizens only.
At noon on 8 February 1945, as the ten Soviet POWs, including Devyataev, were at work on the runway, one of the work gang, Ivan Krivonogov, picked up a crowbar and killed their guard. Another prisoner, Peter Kutergin, quickly stripped off the guard’s uniform and slipped it on. The work gang, led by the “guard”, managed to unobtrusively take over the camp commandant’s He 111 H22 bomber and fly from the island. Devyataev piloted the aircraft.
The Germans tried to intercept the bomber unsuccessfully. The aircraft was damaged by Soviet air defences but managed to land in Soviet-held territory. The escapees provided important information about the German missile program, especially about the V-1 and V-2.
The NKVD did not believe Devyataev’s story, arguing it was impossible for the prisoners to take over an airplane without cooperation from the Germans. Thus, Devyataev was suspected of being a German spy and sent to a penal military unit along with the other nine men. Of the escapees, five died in action over the following months. Devyataev himself spent the remainder of the war in prison.
Devyataev was discharged from the army in November 1945. However, his classification remained that of a “criminal” and was unable to secure long term employment.. Eventually, though, Devyataev found work as a manual laborer in Kazan. Soviet authorities cleared Devyataev only in 1957, after the head of the Soviet space program Sergey Korolyov personally presented his case, arguing that the information provided by Devyataev and the other escapees had been critical for the Soviet space program. On 15 August 1957, Devyataev became a Hero of the Soviet Union, and a subject of multiple books and newspaper articles. He continued to live in Kazan, working as a captain of first hydrofoil passenger ships on the Volga.
In 1972, he published his memoirs.Devyataev was awarded the Order of Lenin, the Order of Red Banner twice, Order of the Patriotic War (first and second class), and many other awards.
He became an honoured citizen of Mordovia Republic, the cities of Kazan, Wolgast and Zinnowitz (Germany).
He died at Kazan in 2002, aged 85, and is buried in an old Arsk Field cemetery in Kazan near a World War II Memorial. There is a museum of Devyataev in his native Torbeyevo (opened 8 May 1975) and monuments in Usedom and Kazan.
