Draft Instructions (7 Feb. 1940) "..... an indication of our intentions to be conveyed to Field Marshall Mannerheim by Brigadier Ling who was shortly leaving for Finland..... The forces which the Allies would be in a position to move into Finland arriving early in April would be prepared to operate on the SALLA front. They would not be prepared to operate on any front south of an east and west line drawn through KEMI."

The hope was that the Soviets would not engage the Anglo-French troops. The Finnish units in the area would then move south. The plan included RAF bombers operating from airfields in Finland.
