In this fictional campaign, British control of Heligoland turns the island into a forward position rather than a possession defended from afar. The surrounding submarines form a blockade of Germany. Their immediate purpose is to make any German attempt to recover Heligoland difficult while keeping pressure close to the opposing coast. The scenario illustrates how forward bases and pre-positioned submarines can change maritime access and sea-denial planning.
