The second submarine through the straits had more luck than AE2. On 27 April, HMS E14 (Lieutenant-Commander Edward Boyle), entered the Sea of Marmara and went on a three-week sortie that was one of the most successful actions of the Allies in the campaign. The quantity and value of the shipping sunk was relatively minor but the effect on Ottoman communications and morale was significant. On his return, Boyle was immediately awarded the Victoria Cross. Boyle and E14 made a number of tours of the Sea of Marmara. His third tour began on 21 July, when he passed the straits, despite the Ottomans having installed an anti-submarine net near the Narrows. HMS E11 (Lieutenant-Commander Martin Nasmith) also cruised the Sea of Marmara and Nasmith was awarded the VC and promoted to Commander for his achievements. E11 sank or disabled eleven ships, including three on 24 May at the port of Rodosto on the Thracian shore. On 8 August, during a later tour of the Marmara, E11 torpedoed the Barbaros Hayreddin. A number of demolition missions were performed by men or parties landed from submarines. On 8 September, First Lieutenant H. V. Lyon from HMS E2 swam ashore near Küçükçekmece (Thrace) to blow up a railway bridge. The bridge was destroyed but Lyon failed to return. Attempts were also made to disrupt the railways running close to the water along the Gulf of İzmit, on the Asian shore of the sea. On the night of 20 August, Lieutenant D'Oyly Hughes from E11 swam ashore and blew up a section of the railway line. On 17 July, HMS E7 bombarded the railway line and then damaged two trains that were forced to halt.
French attempts to enter the Sea of Marmara continued. Following the success of AE2 and E14, the French submarine Joule attempted the passage on 1 May but she struck a mine and was lost with all hands. The next attempt was made by Mariotte on 27 July. Mariotte was caught in the anti-submarine net that E14 had eluded and was forced to the surface. After being shelled from the shore batteries, Mariotte was scuttled.On 4 September, the same net caught E7 as it began another tour. The first French submarine to enter the Sea of Marmara was Turquoise but it was forced to turn back and on 30 October, when returning through the straits, ran aground beneath a fort and was captured intact. The crew of twenty-five were taken prisoner and documents detailing Allied operations were discovered, which included a rendezvous with HMS E20 scheduled for 6 November. The rendezvous was kept by the German U-boat UB-14 which torpedoed and sank E20 killing all but nine of the crew. Turquoise was salvaged and incorporated (but not commissioned) into the Ottoman Navy as the Onbasi Müstecip, named after the gunner who had forced the French commander to surrender.
