On 9 August 1914, U-15 became the first U-boat loss to an enemy warship after it was rammed by British light cruiser HMS Birmingham.

Constructed by Kaiserliche Werft Danzig, U-15 was ordered on 23 February 1909 and was commissioned three years later on 7 July 1912.

The Birmingham's Captain Arthur Duff ordered his crew to fire on the U-boat, but missed.

As U-15 attempted to dive to avoid the attack, Duff ordered for his ship to ram the submarine at full speed, cutting it in half and killing all 23 members of its crew.
