How a 1941 Franco-German naval war might unfold

If France and Germany alone went to war in May 1941, how might their navies fight?

Expect a North Sea clash and French efforts to hunt down Deutschland-class commerce raiders around the world.

The main fleet contact would probably develop in or around the North Sea. France would also need to locate Deutschland-class raiders operating across wider sea lanes. The war would mix fleet concentration close to Europe with dispersed cruiser hunting overseas. A single naval conflict could therefore create very different operational problems at the same time.
