Could the High Seas Fleet exploit the Baltic deployment by attacking Britain or the Channel?
Short answerGermany could threaten northern Britain, but the Channel barrage, mines, coastal destroyers, torpedo boats, and British submarines would make a Channel or Atlantic breakout difficult.
NotesThe High Seas Fleet could attempt a diversion before entering the Baltic. Its practical reach is constrained because the Channel is protected by a barrage, mines, and local British forces. Royal Navy submarines would deploy across likely routes as soon as the German fleet moved. Germany could still threaten the north coast, but its fleet would struggle to reach the Atlantic through the Channel. Political pressure to defend the Baltic coast would also pull it toward Jellicoe's chosen theater. Such a strike is possible, though it offers less than a direct response to the invasion.
