- In Finland, Soviet 4th Division rushed several groups of men across the frozen Suvanto River in the darkness to reinforce the bridgehead on the far bank, but the attempts were detected by Finnish forces, which attacked them with artillery and machine guns, killing many; after dawn, Finnish forces successfully eliminated all Soviet bridgeheads on the Finnish side of the Suvanto River, ending the Battle of Kelja by 1800 hours. Elsewhere, in Suomussalmi, Finnish 9th division, supported by the newly-arrived four 1902 76-millimeter cannon and two Bofors 37-millimeter anti-tank guns, began to assault the encircled Soviet 163rd Division. ww2dbase [The Winter War | CPC]
