The Soviet forces revive their winter offensive this week. More men, more tanks and more artillery are brought in to try to force a breakthrough in the Finnish lines. Meanwhile, Churchill encounters resistance to his plan to cut of the German iron trade with Sweden.

After more than a week of preliminary bombardmends and attacks, the Red Army finally attacks the Finnish defensive positions on the Karelian Isthmus en masse. They throw thousands of troops at the Finns at the entire width of their lines, even exceeding them. The Finns defend the best as they can, but their winning streak seems to come to an end.
