A short time previous to the attack on Cuxhaven, the British submarine B-11 accomplished one of the most remarkable exploits of the war when it penetrated into the Dardanelles and torpedoed the Turkish battleship Messudieh.

ALLIES FORCE THE DARDANELLES

On March 1 a great allied fleet of forty British and French warships, having reduced the forts at the entrance to the Dardanelles, was on its way through the straits and the Sea of Marmora to Constantinople, with the object of capturing the city.

Panic prevailed in the Turkish capital at the approach of the fleet, while for the first time in history hostile flags flew over the forts at the mouth of the Dardanelles.

The naval operations of the Allies in the Dardanelles, which began on February 17, proceeded without any serious check for a month.

] THREE WARSHIPS SUNK On March 18 three of the allied warships were sunk inside the Dardanelles and two crippled by the Turks during a bombardment in which ten vessels of the combined fleet participated.

"At 12:22 o'clock the French squadron, consisting of the Suffren, Gaulois, Charlemagne and Bouvet, advanced up the Dardanelles and engaged the forts at closer range.

The Irresistible, the Ocean and the Bouvet were all sunk in portions of the straits which had been swept clear of anchored mines, and the drifting mines which proved so deadly were undoubtedly set afloat by the Turks, probably under the direction of German officers, on the swift current of the Dardanelles at points near the allied ships after the action began.

On March 24 the allied fleets renewed with vigor their attack upon the forts at the Narrows of the Dardanelles.

ALLIED TROOPS AT THE DARDANELLES

On April 25-27, a strong force of British and French troops under General Sir Dan Hamilton effected a landing on both sides of the Dardanelles, to co-operate with the allied fleets seeking to force a passage through the straits to the Bosporus.

The bombardment of the Turkish forts in the Dardanelles by the allied warships was continued.

On May 12 the British warship Goliath was sunk by a Turkish torpedo during the continued attack by the Allies on the Dardanelles.

In the determined attack on the Dardanelles, land forces of British and French troops co-operated with the combined fleets.

STRUGGLE FOR THE DARDANELLES All through the month of June the Allies continued their desperate struggle for the possession of the Dardanelles, the gateway to Constantinople.

STRUGGLE FOR THE DARDANELLES All through the month of June the Allies continued their desperate struggle for the possession of the Dardanelles, the gateway to Constantinople.

The results of the operations on the Gallipoli peninsula during the month indicated that the Dardanelles would prove a veritable slaughter pen before the Allies succeeded in winning their way to Stamboul.

THE DARDANELLES CAMPAIGN.

The struggle of combined land and sea forces of the Allies to gain control of the Dardanelles, and thus open the way for the British and French fleets to Constantinople and the Black Sea, continued through the autumn of 1915 and furnished some of the most sanguinary battles of the war.

" Commander Wedgwood's first view of fighting at the Dardanelles was at the so-called V beach, where a steamship, the "River Clyde," was run aground to furnish cover for the landing of the British troops.

" Many weeks of bloody fighting followed and while there was talk early in November of a possible abandonment of the Dardanelles campaign, the end of the month found the struggle still in progress, with no end in sight.

Official figures made public October 15, show that the British casualties at the Dardanelles up to October 9 were 96,899, of whom 1,185 were officers.

OPENS UP THE DARDANELLES

On the very last day of October, 1918, Turkey surrendered to the British, opening the Dardanelles and through those waters giving the allied fleets access to the German-dominated Black Sea and the coast of southern Russia, and putting at the mercy of the allies the only active units of the German navy.
