‘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.
An extreme crisis had overtaken the Allied Fleet while Nasmith had been away, and it was every bit as serious as the alarm which he had created in Constantinople. Towards the middle of May news had come through that a U-boat (it was Hersing in the U 21) had been sighted passing through the Straits of Gibraltar. It had been fired at but had got away, and was then presumably headed for Gallipoli.
During the next week, when Nasmith in the E 11 had vanished into the silence of the Sea of Marmara, there had been a growing depression in the Fleet. The Queen Elizabeth had been something of a symbol for the whole expedition, and it had seemed to the soldiers on shore as well as the sailors at sea that a good few of their hopes had gone with her when she sailed away. De Robeck had transferred his flag to the Lord Nelson, and had remained off the peninsula with the other battleships, but it was not the same thing. The Fleet had an apprehensive air. Each day the tension increased, and the men on watch kept seeing periscopes on every side. A gambolling porpoise was enough to raise the alarm, and so were the dead and bloated mules that floated out to sea from the battlefield on shore, their legs projecting to the sky.
In the very early dawn of May 24 a genuine emergency occurred: the old battleship Albion ran her bows on to a sandbank off Gaba Tepe and the Turks fired more than a hundred shells into her while the British tried to tow her off. Eventually the ship lightened herself by firing off all her heavy guns together, and in the recoil she got away. This incident had nothing to do with submarines, and there were under a dozen casualties, yet it was one more addition to the general feeling of insecurity.
Then on the following morning — at the very moment that Nasmith was gliding into the wharves at Constantinople — the Vengeance reported that a torpedo had passed across her bows while she was steaming between Anzac and Helles. It was true enough. Hersing had managed to get into the Austrian port of Cattaro before his oil ran out, and when he had refuelled he came straight through to Gallipoli.
A commotion spread through the Allied ships. De Robeck in haste transferred his flag again from the Lord Nelson to the Triad, a large yacht which had once been a pleasure-going ship along the Bosphorus, and all the more valuable battleships and transports were ordered to retire at once to Mudros. There was a feeling of desolation in the Army as the ships vanished over the horizon leaving behind them an unfamiliar, almost empty sea. Those few of the larger vessels that remained could not disguise the atmosphere of tension in which they waited, hour by hour, for the hidden attack which now seemed bound to come.
Commander Hersing struck at mid-day. He saw the old battleship Triumph near Gaba Tepe with a ring of destroyers circling round her, waited for his chance, and fired. The torpedo passed easily through the Triumph’s nets and the ship at once took a heavy list. For eight minutes, while the destroyers came rushing in to the rescue, she remained at an angle of forty-five degrees, spilling her crew into the sea. Then she capsized and floated for a time with her green bottom upwards in the sunlight. The crews on the neighbouring ships stood to attention as she made her last plunge down to the bottom through clouds of smoke and steam. All this took place in full view of the two opposing armies on the shore, and while the Anzac soldiers watched in dismay a cheer came up from the Turkish trenches. This was the finest sight the enemy had seen since the campaign began, but they had no wish to be vindictive; after a few opening shots no further attempt was made to fire on the wreck or her survivors.
