Karelian Front
The 14th Army fought against both the German and Finnish armies following Nazi Germany's invasion of the Soviet Union in June 1941. Skvirsky was promoted to chief of staff for the recently formed Karelian Front in September 1941. Named commander of the 26th Army in May 1943, he directed the Soviet advance against the Finns in the fighting around Vyborg (Viipuri) and Petrozavodsk (Petroskoi).
