Fokanov held the rank of
kombrig when
Operation Barbarossa, the German invasion of the Soviet Union, began in June 1941. In July the 154th became part of the
63rd Rifle Corps of the
Western Front's
21st Army. During the
Battle of Smolensk, the corps temporarily repulsed German attacks and recaptured
Rogachev and
Zhlobin in a counterattack on 13 July. For his "skilled leadership" of the division during the counterattack, Fokanov was promoted to major general on 31 July. He then led the division with the
3rd Army of the
Central Front in defensive battles on the east bank of the
Dnieper, preventing a German crossing near
Loyev. The division fought in the Oryol–Bryansk and Tula defensive operations in September and the recapture of
Kaluga during the Kaluga Offensive in December as part of the
50th Army, initially with the
Bryansk and then the Western Front. In August 1942, the 154th fought in the
Kozelsk Offensive against the German
2nd Panzer Army, after which the Soviets claimed to have inflicted heavy losses on the German forces and to have forced them onto the defensive. For its "courage and heroism" in the offensive, the division was converted into the
47th Guards Rifle Division. His superiors assessed Fokanov as having shown "bravery and skilled organization of the combined operations of different branches". After the division was transferred to the
Southwestern Front in the
Stalingrad area during October, Fokanov became deputy commander of the front's
5th Tank Army in December during the advance of the latter toward the
Donbas. From April 1943, Fokanov, promoted to lieutenant general on 28 April, commanded the
29th Guards Rifle Corps of the front's
8th Guards Army. He led it during the
Donbas and
Zaporizhia Offensives, during which it helped recapture
Barvenkovo and
Zaporizhia. For his leadership of the corps, Fokanov was awarded the
Order of the Red Banner and the
Order of Kutuzov, 2nd class. From 6 September 1944, he led the
29th Rifle Corps, which, as part of the
48th Army of the
2nd and then
3rd Belorussian Fronts, participated in the
Mława–Elbing and
East Pomeranian Offensives, during which it captured Maków,
Maków Mazowiecki,
Przasnysz,
Allenstein, and
Braunsberg. Subsequently, he distinguished himself in battles to destroy the German forces around
Heilsberg, receiving the
Order of Kutuzov, 1st class. == Postwar ==
