Gulf of Erenköy

At this point the width of the strait is 7,500 metres (24,600 ft) [1] The midpoint of the gulf is known as Karanlık Liman ("Dark Harbor") Administratively is a part of Çanakkale Province.

During the initial naval operations carried on by the Allies of World War I in 1914 November and 1915 February, Ottoman defenders observed that the Allied ships used the gulf of Erenköy as a maneuvering space.

Additionally, 26 mines were laid in the Gulf of Erenköy parallel to the coast line unobserved by the Allies.

The Turkish military became aware of the practice of the Allies battleships making a turn-back manoeuvre in the gulf when they face heavy artillery fire.

Among these, both Bouvet and Irresistible were already hit by the artillery in Turkish redoubt before striking the mine.
