The Allied fleet, comprising 18 battleships with an array of cruisers and destroyers began the main attack against the Dardanelles in 1915.
Despite some damage to the Allied ships engaging the forts by Ottoman return fire, minesweepers were ordered along the straits.
In the Ottoman official account, by 2 pm: "all telephone wires were cut, all communications with the forts were interrupted, some of the guns had been knocked out ... in consequence the artillery fire of the defence had slackened considerably".
The French battleship Bouvet struck a mine, capsized and sank within two minutes of striking the underwater device; 639 of the crew of 710 were killed.
The Minesweepers retreated under Ottoman artillery fire, leaving the minefields largely intact.
HMS Irresistible and HMS Inflexible struck mines and Irresistible was sunk, with most of her crew rescued; Inflexible was badly damaged and withdrawn.
There was confusion during the battle about the cause of the damage; some participants blamed torpedoes.
HMS Ocean was sent to rescue Irresistible but was disabled from an artillery shell, struck a mine, and was evacuated before sinking.
The French battleships Suffren and Gaulois sailed through a new line of mines placed secretly by the Ottoman minelayer Nusret ten days before and were also damaged.
The losses forced de Robeck to sound the "general recall" to protect what remained of his force.
During the planning of the campaign, naval losses had been anticipated and mainly obsolete battleships, unfit to face the German fleet, had been sent.
Some of the senior naval officers like the commander of Queen Elizabeth, Commodore Roger Keyes, felt that they had come close to victory, believing that the Ottoman guns had almost run out of ammunition but the views of de Robeck, the First Sea Lord Jackie Fisher and others prevailed.
Allied attempts to force the straits using naval power were terminated, due to the losses and bad weather.
Planning to capture the Turkish defences by land, to open the way for the ships began.
