The sleet came sideways off the Norwegian Sea as twelve men prepared to assault a lighthouse that was killing Allied sailors by the hundreds.

The Night British Commandos Stormed a Norwegian Lighthouse

Operation Claymore: Churchill's First Strike Back at Hitler's Fortress Europe

British commandos raided a Nazi-held Norwegian lighthouse in 1943, unknowingly saving an Allied convoy from U-boat attack.

The sleet came sideways off the Norwegian Sea as HMS Princess Beatrix cut her engines in the predawn darkness of March 4, 1941. But it was on October 13, 1943, that a lesser-known sequel unfolded—Operation Leader, when British and Norwegian commandos returned to the Lofoten Islands for a mission that would test the very limits of cold-weather warfare.

Sergeant Knut Haukelid pressed his face against the frozen deck rail, watching the silhouette of Værøy Island materialize through the Arctic murk. His breath crystallized instantly. Somewhere on that rock, a German garrison of thirty men guarded a weather station feeding meteorological data to U-boat wolf packs hunting Allied convoys.

The commandos—twelve Norwegians and eight British sappers from No. 12 Commando—descended into rubber dinghies that bucked against three-foot swells. The plan was surgical: neutralize the lighthouse garrison, destroy the weather equipment, and vanish before dawn reached this latitude where the sun barely rose at all.

What intelligence hadn't revealed was the minefield.

💡 The German pressure mines failed to detonate under the first commando because Arctic temperatures had frozen the detonator mechanisms solid—a design flaw German engineers never corrected.
