On December 9 the defenders were reinforced with a newly founded regiment (JR 27). Colonel Hjalmar Siilasvuo was given the command of the Finnish forces and he began immediate counter-measures to regain Suomussalmi. The main forces advanced on Suomussalmi but met resistance that caused the Finns serious losses.
On December 24 the Soviets counter-attacked, but failed to break through the surrounding Finnish forces.
Reinforced with two new regiments (JR 64 and JR 65) the Finns again attacked on December 27. This time they took the village and the Soviets retreated in panic over the surrounding frozen lakes.
During this time the Soviet 44th Division had advanced from the east towards Suomussalmi. It was entrenched on the road between Suomussalmi and Raate. Between January 4 and January 7 the division was divided into isolated groups (known as motti) and destroyed by the Finnish troops.
The Finns captured a great amount of war-booty, including tanks, field-guns and other weapons which were greatly needed by the Finnish army.
