SM U-9 of the Kaiser's Navy. Along with raider
SMS Emden, they were the only ships the Kaiser awarded the Iron Cross.
On 22 September 1914, U-9 sighted a squadron of 3 obsolete Royal Navy
Cressy class 12,000 ton armored cruisers. Within 1 hour, the 6 torpedoes carried by U-9 had sunk all 3 ships, killing 1,450 British sailors.
Wenman "Kit" Wykeham-Musgrave (1899–1989) survived being torpedoed on all three ships.[14] His daughter recalled:
He went overboard when the HMS Aboukir was going down and he swam like mad to get away from the suction. He was then just getting on board the HMS Hogue and she was torpedoed. He then went and swam to the HMS Cressy and she was also torpedoed. He eventually found a bit of driftwood, became unconscious and was eventually picked up by a Dutch trawler.
Remember that the next time you think you are having a bad day...
U-9 eventually sunk another British armored cruiser, 3 British steamers, 10 British fishing vessels and a Russian minesweeper.
