On August 28, 1914, a British naval force of 31 destroyers, two light cruisers, and a submarine force emerged from the early morning mist on a mission deep into German home waters. Their target was Heligoland Bight, a bay on the German North Sea coastline located at the mouth of the Elbe River. Their objective was aggressive and daring: to ambush and destroy the daily German destroyer patrols defending Heligoland Bight. The raid was an aggressive departure from British strategy up to that point in the war, which had consisted of the British Navy utilizing a distant blockade to cut Germany off from their oceanic supply chains. As such, the raid took the Germans by complete surprise.
The Heligoland Operation was the brainchild of British Commodores Roger Keyes and Reginald Tyrwhitt, and their goal for the raid was different from the pre-war British naval strategy against Germany. The raid was not designed to produce a decisive naval engagement between dueling heavy capital ships, but instead centered on light cruisers and destroyers, small and fast ships combining their speed and fast-firing guns to attack the Germans in their home waters to limit German incursion into the North Sea. The British wanted the attack to send a clear message to the German Navy that any German operation in the North Sea, whether large or small, was in perpetual danger of a British attack.
Heligoland Bight was not an easy target. The area is located deep in German home waters and was heavily defended at the outset of the war by several large caliber shore cannons, a zeppelin hanger, and large patrols of destroyers and submarines. It was also a strategic position as it guarded the entrance to Kiel, the major naval anchorage of the German High Seas Fleet. To complicate matters, the British raid force was within striking distance of several powerful German battlecruisers, docked nearby and ready to reinforce German destroyer patrols.
