On 15 December, the battlecruisers of I Scouting Group, led by Hipper, conducted a bombardment of Scarborough, Hartlepool, and Whitby on the English coast. The main body of the High Seas Fleet, commanded by Admiral Friedrich von Ingenohl, stood by in distant support; "Stettin" and two flotillas of torpedo boats screened the rear of the formation. That evening, the German battle fleet of some twelve dreadnoughts and eight pre-dreadnoughts came to within of an isolated squadron of six British battleships. However, skirmishes between the rival screens in the darkness convinced Ingenohl that he was faced with the entire Grand Fleet. Under orders from Kaiser Wilhelm II to avoid risking the fleet unnecessarily, Ingenohl broke off the engagement and turned the battle fleet back toward Germany.
