Another submarine, the E 11, was waiting to take the E 14’s place in the Marmara, and her young captain, Lieut-Commander Nasmith, dined aboard the flagship on the night of May 18 with de Robeck, Keyes and Boyle. It was an animated party. Boyle had been recommended for an immediate award of the Victoria Cross. Keyes, who was still chafing at the withdrawal of the Queen Elizabeth and at the latest refusal of the Admiralty to allow the Fleet to resume its attack on the Narrows, thought he had begun to see a ray of light at last. Having heard Boyle’s story, Nasmith set off that same night, and sixteen hours after leaving the Admiral’s dining-table he was resting on the bottom of the Sea of Marmara. Unknown to anyone he had formed a plan which was more daring than anything which had been attempted before: a direct attack on Constantinople itself.
His first act on coming to the surface near the town of Gallipoli was to seize a Turkish sailing vessel and lash her to the E 11’s side, so that she would act both as a disguise and a decoy. When after several days no target appeared he cast off this Trojan sea-horse and steamed directly up the Marmara.
On May 23 he sank a Turkish gunboat and several other smaller craft, and then on the following day he fell in with the Nagara, a transport that was making its way down to the Dardanelles. There was an American journalist on board the Nagara, Raymond Gram Swing of the Chicago Daily News, and he says he was on deck that morning chatting to a Bavarian doctor. Boyle’s exploits of the previous weeks had become known in Constantinople, and Swing had just remarked to the doctor, ‘It’s a fine morning for submarines,’ when he paused, gazed out to sea in astonishment, and added, ‘And there’s one.’ E 11 broke the calm surface very gently about a hundred yards away, and four men appeared on the conning tower. One of them in a white sweater (it was Nasmith), used his cupped hands as a megaphone: ‘Who are you?’
‘I’m Swing of the Chicago Daily News.’
‘Glad to meet you, Mr. Swing, but what I mean is what ship is that?’
‘The Turkish transport Nagara.’
By now the ship’s crew were in a state of extreme alarm, some coursing about the deck, others, with their fezzes still on their heads, jumping into the sea.
‘Are those marines?’ Nasmith asked.
‘No, they’re just sailors.’
‘Well, I’m going to sink you.’
Swing asked, ‘Can we get off?’
‘Yes, and be damned quick about it.’
The confusion in the Nagara had now reached the point where everyone had begun to scramble over the sides, and the lifeboats were lowered so clumsily that they half filled with water. The Turks were frenziedly baling with their fezzes. As Swing appeared to be the only calm man on board, Nasmith directed him in launching the last boat and in picking up the sailors and passengers who had jumped or fallen into the sea. Nasmith then closed the ship, and an immense orange flame went up as he sank her: she was filled with ammunition.
Soon after this E 11 was driven away from the coast by a detachment of Turkish cavalry, but she managed to chase and sink another transport, and a third ship beached herself on the shore. By now the survivors of the wrecks had raised the alarm in Constantinople, and from early morning on May 25 the Turkish artillery on both sides of the Bosphorus were standing to their guns. In order to calm the population in the event of an action taking place, an announcement was made that there might be firing practice during the course of the day.
The submarine surfaced at 12.40 p.m., and Nasmith saw before him a large freighter, the Stamboul, berthed alongside the arsenal. His first torpedo ran in a circle and on its return narrowly missed the E 11 herself. His second, however, struck home, and he dived, heading through the city into the Bosphorus, while a barrage of artillery crashed over his head.
The panic that now broke out in Constantinople gives an indication of what might have happened had the Allied Fleet appeared there in March. While the Goeben hastily shifted her anchorage into the shelter of her attendant ships, a mob fled through the streets and everywhere the shops ran up their shutters. On the docks all activity ceased, and a contingent of soldiers which was embarking for Gallipoli was precipitately ordered back to the shore again. Now, in one moment, the powder factory on the wharves and the crowded wooden houses on the slopes above seemed utterly exposed, and it was apparent to everyone that there was very little that the fire brigade could do if this was to be the prelude to a serious attack.
Meanwhile, Nasmith and his men were struggling for their lives. The current in the Bosphorus was even stronger than in the Dardanelles, and for some twenty minutes the submarine was out of control, bumping from shoal to shoal along the bottom as far as Leander’s Tower. She was righted eventually, and with great skill Nasmith turned back through Constantinople. ‘The next day,’ here-ported later, ‘was spent resting in the centre of the Sea of Marmara.’
Then on May 27 he resumed his attack, sinking ship after ship in the approaches to the Golden Horn. A terror spread through the Sea of Marmara, for it was thought that at least half a dozen submarines were operating. No vessel of any size was allowed to leave port without an escort of destroyers and gunboats, and these repeatedly tried to ram the E 11 whenever she rose to the surface to attack. Nasmith paused in his operations only when the air in the submarine became so foul that he was obliged to surface in order to allow the crew to come on deck and bathe.
Soon the shortage of torpedoes became the E 11’s chief concern, and those that remained were set to run on the surface so that whenever they missed their targets Nasmith could dive into the sea and recover them. By June 5 a serious defect had developed in the port main motor, the starboard intermediate shaft had cracked, only two torpedoes were left, and Nasmith judged it time to go home. He entered the Dardanelles and steamed down as far as Chanak hunting for the Turkish battleship Barbarossa Harradin, upon which he had made an unsuccessful attack a few days before. He saw nothing, however, except a large transport anchored above Nagara. The E 11 was now in the most dangerous part of the Narrows, and in her crippled state was quite likely to be washed ashore. But it was unbearable to Nasmith that he should leave with two torpedoes still intact; he turned back up the Dardanelles, sank the transport, and then returned for the crucial dive through the Narrows. Off Chanak the trim of the boat became violently affected by the change in the density of the water, and Nasmith dived to seventy feet. About an hour later he heard a scraping noise which seemed to indicate that the keel was hitting the bottom, and since he knew this to be impossible he rose up to twenty feet below the surface to investigate. He saw then that about twenty feet ahead of the periscope a large mine had been torn from its moorings by the port hydroplane and was being towed along. Saying nothing to his crew, Nasmith continued for another hour until he was outside the entrance to the straits. He then went full speed astern with the bows of the submarine submerged and the rush of water from the screws carried the mine away.
There was another dinner aboard the flagship that night, and at the end of it Boyle in E 14 set off again for the Marmara, while Lieut.-Commander Nasmith, V.C., sailed the E 11 to Malta for repairs.
