Location
Cause → Event → Consequence
Germany relied on blockade-runners to import strategic materials through Allied-controlled waters. The Kriegsmarine dispatched destroyers and torpedo boats to rendezvous with an incoming blockade-runner and escort it safely to a French port, prompting the Allies to launch Operation Stonewall to intercept these vessels off the west coast of France.
On 28 December 1943, the Royal Navy light cruisers HMS Enterprise and HMS Glasgow intercepted the German escort force in the Bay of Biscay. In the ensuing confused engagement, the British cruisers sank the German torpedo boats T25 and T26 and the destroyer Z27, neutralising the escort mission.
The loss of three German warships in a single action undermined the Kriegsmarine's ability to protect blockade-runners in the Bay of Biscay, contributing to the broader Allied success in severing Germany's maritime supply lines from overseas sources of raw materials.
