Having foiled the Soviet invasion of the Winter War, the Finns found themselves embroiled in an ongoing conflict to maintain their borders as the Soviets recovered from the initial advances made by the Germans during the Barbarossa campaign. Yet as the red tide of Soviet forces pushed back the German army, the Finnish forces--despite their lack of equipment, obsolete machinery and miniscule manpower--held firm against the Soviets throughout the continuation of the war, ensuring their post-war independence on the Western side of the Iron curtain.

But that was not the end of hostilities for the exhausted Finnish nation as they turned their attentions to the Nazi forces embedded within their territory, calling up brigades populated with teenagers to force German forces inexorably back.

Featuring some incredible, never-before-seen photographs and firsthand accounts, this is the history of one of the most incredible moments in modern military history.
