During the Winter War, Dyachenko served in 25 IAP, which was equipped with Polikarpov I-153s
7 March 1940 was another day of heavy claiming from 7 IAP when they claimed seven bombers and one fighter.
Leitenant Aleksandr Moshin (credited to him as a single destroyed by Bykov), Sayenko and Malyshev of 2./7 IAP (I-16) claimed a shared Blenheim over Koivisto peninsula.
Viktor Skryabin of 2./7 IAP (I-16) claimed a Blenheim over Vilaniemi.
Kuzmenko of 5./7 IAP (I-153) claimed a fighter.
Golubev and Tikhomirov of 5./7 IAP (I-153) claimed a shared Blenheim.
Ilya Kainov and Balashov of 5./7 IAP (I-153) claimed a shared Blenheim.
Kainov later claimed a second shared Blenheim with Rybalov (from the same unit).
Major Aleksandr Ketov (credited to him as a single destroyed by Bykov), Vladimir Semenishin and Vavilov of 1./7 IAP (I-16) claimed a shared Blenheim.
Starshii Leitenant Fedor Shinkarenko of 4./7 IAP (I-16) claimed a Blenheim.
To add to the confusion did Starshii Leitenant Dyachenko of 25 IAP (I-153) claim a shared Blenheim at kv. 093 (28. AK sector) together with 7 IAP but it’s unclear with whom.
Two Finnish Blenheims were in fact lost in the Viborg area when LeR 4 attacked targets on the ice of the Gulf of Vyborg and on the shore on 24 sorties during the day.
Blenheim BL-144 of LLv 42 was lost at 07:30. The pilot kersantti Toivo Hyytiäinen and gunner kersantti Eelis Turunen were killed while the observer vänrikki Kauko Nykänen parachuted to become a PoW.
Blenheim BL-122 of LLv 46 was lost at 12:15. The pilot luutnantti Niilo Hakla parachuted wounded while the observer luutnantti Pekka Salokoski and gunner kersantti Arvi Pakkala both were KIA.
Dyachenko ended the war with 1 shared biplane victory.
