After the return of Lieutenant Commander Boyle VC from the Sea of Marmara, Turkey, on 18 May 1915, Commodore Keyes ordered Lieutenant Commander M E Nasmith of HM Submarine E11 ‘go and run amok in the Marmora’. Nasmith made his way through the Dardanelles into the Sea on 19 May. On 23 May E11 torpedoed an enemy gun boat, Pelenk- I-Dria, off Constantinople, which, however, managed to knock out one of the submarine’s periscopes. On the 24th, E11 stopped and blew up a small steamer and then pursued another steamer into the harbour of Rodosto (Tekirdag), halfway along the northern coast of the Sea, and torpedoed her, before attacking a paddle steamer. On 25 May E11 raided the harbour of Constantinople. Although her two torpedoes were relatively ineffective, damaging a wharf and steamer and sinking a troop barge, the attack caused panic in the capital. On 27 May Nasmith tried unsuccessfully to torpedo the Turkish battleship Heireddin Barbarossa but on the following day sank a supply ship off the northern shore. On the 31 May E11 torpedoed and damaged a steamer off Panderma (Bandirma) on the southern shore of the Sea, and on 2 June she sank an ammunition ship. E11 was now short of ammunition and other stores, as well as having mechanical problems. On 7 June Nasmith sailed back through the Dardanelles, briefly turning back to sink a Turkish transport ship. The Submarine then snagged a Turkish mine which it towed for some miles before freeing itself. Nasmith was awarded the VC for the successful voyage, his two officers the DSC and the remaining crew the DSM.
For most conspicuous bravery in command of one of His Majesty’s Submarines while operating in the Sea of Marmora. In the face of great danger he succeeded in destroying one large Turkish gunboat, two transports, one ammunition ship and three storeships, in addition to driving one storeship ashore. When he had safely passed the most difficult part of his homeward journey he returned again to torpedo a Turkish transport.
