The Red Army pushed through the Finnish lines to Vyborg and all the way to tali_ihantala but never through the Taipale front in the east of Karelian Isthmus.Another miracle of the battles in 1939-1944 until the peace treaty.The line here is defensive line but Taipale stayed in Finnish hands which can be considered a miracle even inthe west the Red Army pushed to the north-west of Viipuri. Once Vyborg was taken Stalin sent vodka for the troops to drink for three days. Perhaps a mistake if you wanted to conquer Finland as the Finnish troops arrived to the battle scene fron northern Karelia as well as the German panzerfausts which had been kept in secret in the western Finland.( Turku).
