A counterfactual dash by the High Seas Fleet through the Dover Strait exposes a larger geographic problem. Passing the patrol line would not solve the problem because the fleet could not sail home around Britain. A return through the same confined waters would become dangerous once local forces delayed the Germans and the Grand Fleet approached from the north. Channel geography could therefore turn a tactical breakthrough into a trap.

Why a High Seas Fleet dash through the Channel risked entrapment
A German breakthrough into the Channel still left the High Seas Fleet with no safe return route if British tripwires delayed it until the Grand Fleet closed from behind.
