There was a gate in the middle of the net, and unless the submarines were lucky enough to strike it their only way of getting through the wire was to ram it at full speed underwater and hope for the best. Boyle described this experience: ‘I missed the gate and hit the net. I was brought up from eighty feet to forty-five feet in three seconds, but luckily only thrown fifteen degrees off my course. There was a tremendous noise, scraping, banging, tearing and rumbling, and it sounded as if there were two distinct obstructions, as the noise nearly ceased and then came on again, and we were appreciably checked twice. It took about twenty seconds to get through.’
But Cochrane on his next trip did not get through. Hopelessly entangled, he fought the net for twelve hours on the bottom of the straits while bombs exploded about him, and it was only when the hull was leaking and the lights had failed that he burned his papers and rose to the surface to surrender.
Nasmith, Boyle and the others were not deterred; they continued to pass through, and by the end of the year the net was so damaged by their repeated rammings it had almost vanished altogether. Up to the last, however, the passage through the Narrows remained an ordeal of the most frightening kind, and perhaps from that very fact it acted as a psychological stimulus on the crews. One seems to have read the story in some boyhood book of sea adventure: the pirates’ cave with its treasure lies hidden in the cliffs, but one has to make a dangerous dive beneath the sea to reach it. And some get through and some get trapped halfway.
There is an almost dolphin-like air, a precise abandon, in the way the E-boats frisked about at times. On seeing a convoy, the commanders would deliberately surface and pretend to be in difficulties so as to entice the protective gunboats away. Then, diving deep, they would turn back and demolish the boats of the convoy one by one. They shot up the caravans of camels and bullock carts making their way down the Bulair isthmus with loads of barbed wire and ammunition. When they were short of fresh food they surfaced beside the Turkish trading caiques and provided themselves with fruit and vegetables. Wherever they could they saved their torpedoes and their ammunition by boarding enemy ships and simply opening the sea-cocks or placing a charge on the keel. Sometimes prisoners were carried around for days on end before they could be put ashore, and these were often very strange people — Arabs in their desert robes, sponge-divers and Turkish Imams, and once a German banker, wearing only a short pink vest, who complained that 5,000 marks in gold had just been sent to the bottom.
When more than one submarine was operating the commanders would make a rendezvous, and with their vessels tied up together far out in the Sea of Marmara they would exchange information for an hour or two, while their crews bathed in the sunshine; and then perhaps they would go off on a hunt together. Once there was a disaster. The French Turquoise ran aground and was captured. Enemy intelligence officers found in the captain’s notebook a reference to a meeting which he was to have at sea in a few days’ tine with the British E 20. It was a German U-boat that kept the rendezvous, and she torpedoed E 20 directly she came to the surface. Only the British commander and eight of the crew who were on deck survived.
In August Nasmith sank the battleship Barbarossa Harradin. Expecting that she would come south to take part in a new battle on the peninsula, he lay in wait for her at the top of the Narrows — having, on the way through, scraped heavily against a mine. The battleship appeared in the early dawn escorted by two destroyers, and she was taken utterly by surprise. She capsized and sank within a quarter of an hour.
Nasmith then went on to Constantinople and arrived just at the moment when a collier from the Black Sea had berthed herself beside the Haidar Pasha railway station. Coal at this time had become more precious than gold at Constantinople, since it was so scarce and since everything depended upon it — the railways and the ships, the factories, the city’s supply of light and water. A committee of officials was standing on the wharf discussing how the coal should be apportioned when E 11’s torpedo struck and the ship blew up before their eyes.
Next the submarine turned into the Gulf of Ismid, where the Constantinople-Baghdad railway ran over a viaduct close to the sea, and there d’Oyly-Hughes, the first officer, swam ashore and blew up the line. Like Freyberg at the beginning of the campaign, he was half dead when the E 11 picked him up again.
There were in all 13 submarines engaged in the Sea of Marmara, and although 8 were destroyed the passage was made 27 times. The Turkish losses were 1 battleship (apart from the Messudieh sunk in the previous year), 1 destroyer, 5 gunboats, 11 transports, 44 steamers and 148 sailing boats. Nasmith’s bag alone was 101 vessels, and he was in the Marmara for three months, including a stay of 47 days — a record that was never surpassed in the first world war. By the end of the year all movement of enemy ships by daylight had practically ceased, and with rare exceptions only the most urgent supplies were sent by sea to the peninsula.
It is doubtful if the success of the submarines was ever fully understood by the British while the campaign was going on. At Hamilton’s and de Robeck’s headquarters the sinkings seem to have been regarded more in the nature of a delightful surprise, a bonus on the side, than as the basis for a main offensive. It never seems to have occurred to them that they might have followed up d’Oyly-Hughes’ adventure, that commandos might have been landed north of Bulair to have cut the Turkish land route to the peninsula.
Nor were the Germans any more imaginative. Five small U-boats were eventually assembled at Pola, and managed to get through to Constantinople, but apart from one or two lucky shots at transports coming out of Alexandria they made no further attempt on the Fleet at Gallipoli. By September forty-three German U-boats had been sent to the Mediterranean, but the bulk of the pack remained in the western half of the sea, and they failed to sink any of the ships bringing reinforcements out from England.
And so there was, even as early as May, some reasonable chance of the expedition gathering impetus again. If the Allies were being starved of supplies, so too were the Turks; the lost British battleships were being replaced by monitors, and with the arrival of the Lowland division Hamilton’s forces outnumbered the enemy in the peninsula.
Hamilton in any case was an optimistic man. The sinking of the battleships had been a terrible blow, and on board the Arcadian the General himself was living in the most insecure conditions, so insecure indeed that two transports were lashed to the ship’s side to act as torpedo-buffers. Dismayed but still buoyant, he wrote in his diary: ‘We are left all alone in our glory with our two captive merchantmen. The attitude is heroic but not, I think, so dangerous as it is uncomfortable. The big ocean liners lashed to port and starboard cut us off from light as well as air, and one of them is loaded with Cheddar. When Mr. Jorrocks awoke James Pigg and asked him to open the window to see what sort of a hunting morning it was, it will be remembered that the huntsman opened the cupboard by mistake and made the reply, “Hellish dark and smells of cheese.” Well, that immortal remark hits us off to a T. Never mind. Light will be vouchsafed. Amen.’
Useless now to reflect that the Triumph and the Majestic—and the Goliath too — might have gone to a better end by making a new attempt on the Narrows; or to think of how the great armada of battleships had been scattered and forced to retire into the harbour at Mudros whence it had so confidently set out a month before. The only thing to do now was to wait for news from London, to hope for reinforcements and to hold on.
