Remember, also, that the strait was strongly guarded on either side by a number of Turkish forts, while mines were laid in the water all around. The distance from the entrance of the Dardanelles to Constantinople is about 230 miles. One day the British submarine E11, under Lieutenant-Commander Nasmith, set out on a voyage to Constantinople, where there were several Turkish troopships carrying men who were to be sent to fight us in the Gallipoli Peninsula. This little boat had to pass under or round the mine-fields; to dodge the Turkish destroyers; to avoid being detected by the guns of the shore batteries; and to be prepared to spend long hours under water. All these things were done, and a great deal more, so much, indeed, that it is difficult to believe that one little boat could do so much. It was the means of destroying a Turkish gunboat, two troopships, one powder-ship, and three storeships, while it drove another storeship ashore. Then the plucky little E11 set out for home and passed safely through the most difficult part of the return journey. But even yet its daring work was not completed; for it returned to torpedo another Turkish troopship! The brave and resourceful commander well deserved the Victoria Cross which was granted to him by King George. The British submarine B11 had an even more adventurous journey in the same quarter. In the month of December of the first year of the war the British fleet was waiting for a fitting time to bombard the forts at the entrance to the Dardanelles; and in order to pass the time of waiting Lieutenant-Commander Norman D. Holbrook set out on a voyage of adventure. There was a large mine-field at the entrance to the Straits consisting of several rows of mines. The B11 dived under these mines and came safely within the straits. Then a torpedo was fired at a Turkish battleship named the _Messudiyeh_, and in a very short time the vessel heeled over and then settled slowly down. Meanwhile the periscope was sighted from the batteries on the shore as well as by the torpedo boats which were patrolling the Straits, and in a very short time the shells were hissing around it. But it dodged them cleverly, and after sighting the battleship so as to make quite sure that it was really sinking, the B11 set out on the return journey.
