While the diplomats were laboring with questions arising from the loss of the Lusitania, at a moment when tension between the United States and Germany was acute, came the sinking of the Arabic, on August 19, 1915, with the death of two Americans and thirty-odd British citizens out of 391 persons aboard. The attack took place near Fastnet Light, not far distant from the spot where the Lusitania was sunk. Like the latter ship the Arabic was struck without warning, two torpedoes penetrating her side. She was a vessel of 15,801 tons and, although in service for a number of years, was rated as one of the first-class Atlantic liners. Previous to the attack she had been chased on several occasions by undersea craft, but had always managed to elude them.
The outcry that followed this event in the United States gave the situation as regarded Germany a graver aspect than before. She had been warned that this country would hold her to strict accountability for the lives of its citizens. Berlin, asked if a submarine sank the vessel, followed by immediate disclaimers of any belligerent intent. It was alleged that a German submarine had been in the act of attacking another British vessel when the Arabic hove into view and attempted to ram the submarine. In defense the latter's captain sank the liner, Berlin explained.
This theory was not in the least acceptable to the United States. Captain Finch of the Arabic and other persons aboard had seen the attack on the second ship, and the Arabic attempted to flee but was overhauled and torpedoed. The facts were attested to by such a number of persons that there could be little doubt of their correctness. But despite this and Germany's oft-repeated assurances of respect for American lives, nothing of a positive character was done by the United States. Negotiations dragged out to a wearisome length and the submarines continued to take their almost daily toll from neutrals and belligerents alike.
The British submarine E-7 was sunk by a Turkish land battery in the Sea of Marmora on September 4, 1915, thirty-two men being lost. She was the first undersea boat of the Allies to meet that fate in the Dardanelles operations.
The combination of care and luck that had kept British transports inviolate for more than a year, which ended with the sinking of the Royal Edward, was to be reversed during the coming months when German submarines inflicted heavy losses on this class of ships. The Mediterranean proved to be the grave of several thousand men lost in this manner. The Ramazan, of 3,477 tons, bringing native troops from India, was torpedoed and sunk on September 19, 1915, in the Ægean Sea. Out of about 1,000 men on board some 300 were landed at Malta. The levy which she had aboard consisted of Sikhs and Gurkhas. The sea was new to these men, drawn from interior provinces, and they had embarked upon their first voyage with all the misgivings which usually accompany that experience. The panic among them when the Ramazan was hit may well be imagined. Hints of it crept into the British press, but it was said that after a few wild minutes the officers got their men in hand and all died together with true British fortitude.
One of the few announcements made by Germany concerning lost submarines was given out on September 27, 1915, whether for diplomatic reasons or otherwise it would be difficult to say. The U-27, it was said, had not been heard from since August 10, 1915, and was deemed to have been sunk or captured. Berlin concluded with the observation that the U-27 might have been destroyed after sinking the Arabic, inasmuch as none of her commanders had reported the torpedoing of the liner up to that date. It was Germany's plea at the time that she knew nothing officially of the Arabic's loss. The disappearance of the U-27, a new and fast submarine having seventeen knots speed on the surface, therefore, was a matter of diplomatic importance. The puzzle never was answered.
For some unexplained reason Great Britain never resorted to submarine attacks upon German shipping in the Baltic Sea until the fall of 1915. While her own vessels were being sunk she spared those of her enemy, either because the navy had not been prepared to undertake an expedition into the Baltic, or because it had been looked upon as a small issue in the face of graver problems. This situation was changed by the German threat against Riga, Russia's important Baltic port, following the fall of Libau and the progress of German troops in Courland within cannon range almost of Riga.
It was determined to send a squadron of submarines into the Baltic as a means of assisting Russia and for the purpose of stopping supplies being sent to Germany from Sweden. Commanders of the undersea boats were specifically directed to see that all passengers and crews were taken off merchant ships before they were sunk. These orders were carried out in detail, not a single noncombatant having lost his life as a result of the operations that ensued.
The E-13, with several other submarines, was bound for the Baltic when she ran aground. This was in Danish waters off the island of Saltholm, between Copenhagen and Malmö. She struck early in the morning and all efforts to gain open water failed. At five a. m. a Danish torpedo boat appeared and informed the commander that twenty-four hours would be given him to leave the three-mile zone. Shortly afterward a German destroyer came up and remained close by until two additional Danish torpedo boats reached the scene. The German withdrew, but reappeared about nine o'clock, accompanied by a second destroyer. The three Danish boats were close at hand, but neither they nor the British crew had an inkling of what was to follow.
One of the German destroyers hoisted a signal, but this was pulled down so quickly that the E-13's commander failed to read it. The German then fired a torpedo at the helpless craft, which struck the bottom near by without doing any damage. This was followed with a broadside from every gun that could be brought to bear.
