SM UC-71: Introduction

Sun, 17 May 2026 00:00:00 GMT

She finished the war. That is the first strange thing about SM UC-71. Most of her sisters - the Type UC II minelayers that the Kaiserliche Marine sent out to choke British shipping lanes from late 1916 onward - did not. They were rammed, depth-charged, mined, scuttled on patrol, or simply never returned. UC-71, ordered in January 1916 and commissioned that November, made nineteen patrols and was credited with sinking sixty-three vessels by torpedo or by the mines she laid in the approaches to British ports. When the armistice came on 11 November 1918, she was still afloat. Three months later, on 20 February 1919, she sank in the North Sea while on her way to be surrendered. A German news report eighty-four years later confirmed what crews and historians had long suspected: her own men had scuttled her rather than hand her over.

The Type UC II submarines were designed for one job above all others: to creep into the approaches of an enemy port, dispense a string of contact mines from those six vertical tubes in the forward casing, and slip away before anyone realised what had passed through. The mines did...

SM UC-71: The Surrender That Wasn't

Sun, 17 May 2026 00:00:00 GMT

The Armistice of 11 November 1918 required Germany to surrender her U-boat fleet. The boats were to sail to British ports under German skeleton crews and be handed over to the Royal Navy. Most went. Some did not. UC-71, on her surrender voyage in February 1919, sank in the North ...

SM UC-71: Still Down There

Sun, 17 May 2026 00:00:00 GMT

The wreck of UC-71 lies in the North Sea between Heligoland and the Frisian coast - the same approximate water she patrolled, sometimes through the very minefields HMS Ariel and her sisters had laid. Modern divers have located the hull. The boat is intact enough that the design d...
