What could the Royal Navy do with North Sea supremacy after neutralizing the High Seas Fleet at Jutland?
Short answerPush toward the Baltic, cut German access to Swedish imports, restrict Baltic operations, and threaten an amphibious landing.
NotesThe answer extends sea control beyond winning a battle. Destroying the High Seas Fleet would free the Royal Navy to press toward the Danish straits and the Baltic approaches. That movement could tighten the blockade on Swedish iron ore and food imports while restricting German naval operations in the Baltic. British forces could also prepare an amphibious threat against Germany's Baltic coast. A decisive tactical victory at Jutland would thus create economic and geographic leverage far beyond the North Sea battlefield.
