As Hogue approached her sinking sister, the ship's captain, Wilmot Nicholson, realized that it had been a submarine attack and signalled Cressy to look for a periscope although his ship continued to close on Aboukir as her crew threw overboard anything that would float to aid the survivors in the water. Having stopped and lowered all her boats, Hogue was struck by two torpedoes around 06:55. The sudden weight loss of the two torpedoes caused U-9 to broach the surface and Hogues gunners opened fire without effect before the submarine could submerge again. The cruiser capsized about ten minutes after being torpedoed as all of her watertight doors had been open, and she sank at 07:15.Massie, pp. 133–135
