Finland is now gripped by civil war, with Reds and Whites fighting to determine the future direction of the country. The Reds look to Soviet Russia for support while some of the Whites seek aid from Germany. With the signing of the Treaty of Brest-Litovsk, German attention should be shifting away from the East, but Ludendorff is keen to ensure the emergence of a pro-German regime in Finland, as this will allow him to threaten Petrograd in the event that the Russians renege on their commitments.
A German naval expedition has already landed on Finnish Åland Islands, joining a Swedish force ostensibly there to protect the Swedish-speaking islanders. Now the Germans sign an agreement with the White Finns, recognising their independence and promising military aid against the Reds. But the agreement binds Finland tightly to the Germans: has Finland achieved independence from one imperial master only for the Whites to squander that freedom by turning the country into a German satellite?
