The image at left comes from a postcard by Raphael Tuck and Sons, published around 1908, and features the British armoured cruiser H. M. S. Aboukir. She was launched in 1900 by Fairfields of Govan, Scotland and, on completion two years later, had a short career in the Mediterranean before being withdrawn from service and laid up in reserve in 1912. The rapid development of warships at the time had made her, and the rest of the “Cressy” class to which she belonged, practically obsolete.
She was recommisioned on the outbreak of war in August 1914 and sent on patrol with the 7th Cruiser Squadron to guard the eastern approaches to the English Channel. On the morning of 22nd September, she was torpedoed by the German submarine U-9 and when Cressy and Hogue closed to rescue survivors, they were dispatched in the same way. Three cruisers and over 1400 men were lost in less than an hour. You can find the crew list here. Writer Antoine Vanner gives a thorough description of the disaster on his blog.
This image by artist, Norman Wilkinson, was printed in ‘Earl Kitchener and the Great War’ (1916). Captions in the book claim “one of the sailors described the last moment as follows: “The captain sings out an order just like on any ordinary occasion, ‘If any man wishes to leave the side of the ship he can do so, every man for himself,’ then we gave a cheer and in we went.”
“The horrors of modern warfare are illustrated by the notice issued after this disaster by the British Admiralty, which reads in part, ‘no act of humanity, whether to friend or foe, should lead to neglect of the proper precautions and dispositions of war, and no measure[s] can be taken to save life which prejudice the military situation.'”
Translated into plain language – in the event of this situation being repeated, commanders must put their own ships’ safety first and leave men in the water to their fate.
