Days to Remember by John Buchan — Read

The war record of the British submarine service is unique; the difficulties and dangers which our men faced and overcame were such as no other navy has attempted. The patrol of the shallow Belgian coast and the hunting down of U-boats was a very different task from torpedoing merchant vessels or hospital ships without warning; and the campaigns in the Marmora and the Baltic were conducted under conditions which had no parallel elsewhere.

A glance at the map will show that the Marmora was not only distant from the British naval base, but that the only line of approach was of an uncommonly formidable character. The channel of the Dardanelles is narrow and winding, with a strong tide perpetually racing down it, and setting strongly into its many bays. It was, moreover, protected by forts with powerful guns and searchlights and torpedo tubes, and by barrages of thick wire and netting; it was also patrolled constantly by armed ships. Yet all these defences were evaded or broken through with marvellous courage and ingenuity; for nearly a year a succession of brilliant commanders took their boats regularly up and down the passage, and made the transport of Turkish troops and munitions first hazardous and finally impracticable. Two battleships, a destroyer, and five gunboats fell to them, besides over thirty steamers, many of which were armed, nine transports, seven ammunition and store ships, and no less than 188 sailing ships and dhows with supplies. It is hardly necessary to add that in no case was violence done to neutrals or non-combatants.
