HMS Undine (N48): Introduction

Sun, 17 May 2026 00:00:00 GMT

At 0940 on 7 January 1940, in shallow water off the German island of Heligoland, the captain of HMS Undine made the call that submarine captains hope never to make. His sonar had failed days earlier - a slow leak somewhere in the hydrophone housing - and he had been hunting blind in waters thick with German minesweepers. After a brief gunfight in which his torpedoes missed, he took the boat down to fifty feet and waited in silence. Five minutes passed with no further depth charges. He raised the periscope to look. An explosion immediately tore into the hull. He gave the order to abandon ship. As his crew came out of the hatches, the men still aboard opened the vents and let the sea take their submarine. Undine was the lead ship of an entire class of British submarine. She had been in the war for four months.

HMS Undine (N48): Blind in a Shooting Gallery

Undine was on her fourth war patrol when her sonar gave up. A small leak in the hydrophone fitting was enough to silence the boat's ears entirely. The crew kept going. At 0940 on 7 January, German auxiliary minesweepers M-1201, M-1204, and M-1207 spotted her. Undine launched torp...

The crew got out. They opened the main vents to flood the boat and went into the cold January North Sea, where the Germans pulled them aboard the minesweepers. Of Undine's company of 27 men, every single one survived to spend the rest of the war as prisoners. As lost-submarine st...
