The counterfactual becomes a naval logistics problem once Germany considers moving troops by sea. British merchant shipping favored slower cargo vessels, while Germany's liner fleet was built to carry large numbers of people quickly. Those liners create a possible, though difficult, route around Belgium toward northern French ports. Success depends on timing, escort, French coastal defenses being weaker than the High Seas Fleet's firepower, and the French army being in the wrong place.
