Career

On 16 July 1914 the crew of U-9 reloaded her torpedo tubes while submerged, the first time any submarine had succeeded in doing so.

On 1 August 1914, Kapitänleutnant Otto Weddigen took command.

On 22 September, while patrolling the Broad Fourteens, a region of the southern North Sea, U-9 found a squadron of three obsolescent British Cressy-class armoured cruisers (HMS Aboukir, HMS Hogue, and HMS Cressy), sardonically nicknamed the "Live Bait Squadron", which were assigned to prevent German surface vessels from entering the eastern end of the English Channel. She fired all six of her torpedoes, reloading while submerged, and sank all three in less than an hour. 1459 British sailors died.[11] It was one of most notable submarine actions. Members of the Admiralty who had considered submarines mere toys no longer expressed that opinion after this event.

On 15 October, U-9 sank the protected cruiser HMS Hawke.

On 12 January 1915, Johannes Spiess relieved Weddigen, and commanded U-9 until 19 April 1916. During this period, she sank 13 ships totalling 8,635 tons: 10 small fishing vessels and three British steamers (Don, Queen Wilhelmina and Serbino).

After April 1916, she was withdrawn from front-line duties and used for training.

Besides the raider Emden, U-9 is the only ship on which Kaiser Wilhem II ever awarded an Iron Cross.
