Strategic Narrative Overview
Approaching the barrage on the night of 26–27 October 1916, the German torpedo boats were challenged by the British destroyer HMS Flirt, triggering an engagement. The Germans sank Flirt and then successfully attacked the drifters maintaining the barrage. A British flotilla of destroyers was dispatched to intercept the raiders. The Germans engaged this relief force, fought it off, and then withdrew across the North Sea before daylight, completing the operation largely on their own terms.
01 / The Origins
By 1916, Britain had established the Dover Barrage — a line of patrol vessels and nets — across the Strait of Dover to prevent German submarines from passing into the Atlantic. The German Imperial Navy's Flanders Flotilla, based on the Belgian coast, sought to disrupt this barrage and destroy Allied shipping in the strait. Two and a half flotillas of German torpedo boats were assembled for a night raid against the barrage's drifters and supporting vessels.
03 / The Outcome
The Germans withdrew having inflicted disproportionate losses: Britain lost the destroyer HMS Flirt, a transport vessel, and several drifters, while only one German torpedo boat sustained minor damage. The raid exposed weaknesses in the Dover Barrage and prompted the British to review the barrage's night patrol arrangements. No German vessels were sunk, making the engagement a tactical success for the Flanders Flotilla.
