As soon as this clearance was made the Albion, Vengeance and Majestic steamed into the strait and attacked Fort Dardanos, a fortification some distance below the Narrows. The Turks replied vigorously, not only from Dardanos but from batteries scattered along the shore. Believing that the Turks had abandoned the forts at the entrance, landing parties of marines were sent to shore. In a short time, however, they met a detachment of the enemy and were compelled to retreat to their boats. The outer forts, however, were destroyed, and their destruction was extremely encouraging to the Allies. For a time a series of minor operations was carried on, meeting with much success. Besides attacks on forts inside of the strait, Smyrna was bombarded on March the 5th, and on March the 6th the Queen Elizabeth, the Agamemnon and the Ocean bombarded the forts at Chanak on the Asiatic side of the Narrows, from a position in the gulf of Saros on the outer side of the Gallipoli Peninsula. To all of these attacks the Turks replied vigorously and the attacking ships were repeatedly struck, but with no loss of life. On the 7th of March Fort Dardanos was silenced, and Fort Chanak ceased firing, but, as it turned out, only temporarily. Preparations were now being made for a serious effort against the Narrows. The date of the attack was fixed for March 17th, weather permitting. On the 16th Admiral Carden was stricken down with illness and was invalided by medical authority. Admiral de Roebeck, second in command, who had been very active in the operations, was appointed to succeed him. Admiral de Roebeck was in cordial sympathy with the purposes of the expedition and determined to attack on the 18th of March. At a quarter to eleven that morning, the Queen Elizabeth, Inflexible, Agamemnon, Lord Nelson, the Triumph and Prince George steamed up the straits towards the Narrows, and bombarded the forts of Chanak. At 12.22 the French squadron, consisting of the Suffren, Gaulois, Charlemagne, and Bouvet, advanced up the Dardanelles to aid their English associates. Under the combined fire of the two squadrons the Turkish forts, which at first replied strongly, were finally silenced. All of the ships, however, were hit several times during this part of the action. A third squadron, including the Vengeance, Irresistible, Albion, Ocean, Swiftshore and Majestic, then advanced to relieve the six old battleships inside the strait. [Illustration: THE LOSS OF THE “IRRESISTIBLE” During an attack on the Dardanelles the British battleship “Irresistible” struck a Turkish mine and sank in a few minutes. Severe losses of similar character demonstrated that it would be impossible to force the strait by naval attack.]
