I met Commander Nasmith one afternoon at Kephalo. He had just returned from an aeroplane flight up the Narrows after an investigation of the net defence placed across at that point to prevent submarines from penetrating into the Sea of Marmora. He did not seem very much impressed, and his judgment was justified next day when he took E11 through the defences and arrived in Marmora without mishap. The train-like regularity with which our submarines have accomplished this task is apt to make the venture appear commonplace to the newspaper reader, who may imagine that there is some easy road which, when once found, is plain-sailing. Nothing could be further from the truth. Every submarine that goes up does so with the full knowledge of the dangers to be faced, and the occasional loss of one of them shows the perils incurred. In the early stages of the operations the net across the Narrows could be negotiated by diving under it; but, on a subsequent occasion, a submarine returning to the open sea found that the Turks had placed a deeper net in position. This particular submarine fouled the net at a depth of over one hundred feet, and was actually hung up by stout wire for upwards of fifteen minutes. It is impossible to imagine anything more likely to unnerve men than to be caught like herrings in a net below the surface, and actually to hear, as they did, hydrostatic bombs exploding around them. The Turks would know, of course, by the agitation of the net above, that a submarine was caught; however, by going astern and then ahead, and allowing her whole weight to come on the net, the vessel broke through and returned in safety.
