Would the French Navy join the Baltic operation?

Would France recognize the operation's importance and send naval support?

French leaders would probably resist at first because Britain had removed troops from the Western Front and secrecy limited advance consultation, with naval support more likely only after the result became clear.

France would care most about the land war and the removal of II Corps from the Western Front. That withdrawal would create political friction and could reveal that Britain was preparing a major operation. The French Atlantic Fleet was also largely committed to the Mediterranean. Maintaining surprise would discourage Britain from explaining the plan early enough for French forces to coordinate. France would probably stay outside the opening move and react only after success or failure became clear. Coalition politics puts a real price on the secrecy that gives the naval operation its best chance.
