"May 24th, 10.30 A.M.: Observed small steamer proceeding to the westward. Examined vessel through periscope, and rose to surface on her port quarter. Signalled her to stop. No notice was taken. Brought her to a standstill by several rounds from a rifle directed at her bridge. Ordered crew to abandon the ship. This they carried out with reckless haste, capsizing all but one boat. Fortunately with this boat they were able to right the other two and pick up those swimming in the water. An American gentleman then appeared on the upper deck, who informed us that his name was Silas Q. Swing, of the 'Chicago Sun,' and that he was pleased to make our acquaintance. He then informed us that the steamer was proceeding to Chanak with Turkish marines, and that he was not sure if there were any stores on board. "Ran up alongside and put Lieutenant D'Oyly-Hughes on board with demolition party. He discovered a 6-inch gun lashed across the top of the fore-hatch--the forehold containing one large 6-inch gun mounting and several small 12-pdr. pedestals, the guns for which were probably at the bottom of the hold. "The after-hold was full of 6-inch projectiles, and on top of this were resting about fifty large white-metal cartridge-cases marked Krupp. The demolition charge was then placed against the ship's side in the after-hold, well tamped with 6-inch shells and cartridges. All hands returned to the boat and the charge was fired. The vessel exploded with a loud report, and a large column of smoke and flame shot up." At 11.15 A.M. "E 11" dived into Rodosto harbour after a heavily-laden store-ship. At 12.35 she torpedoed her as she lay alongside the pier. In the afternoon she missed a paddle-steamer which managed to save herself by beaching. On the 25th "E 11" dived into Constantinople and torpedoed a steamer alongside the arsenal. On the 28th she sank a large supply ship. On the 31st she torpedoed a large vessel lying in Panderma Roads. On June 2nd she got another, which was probably--from the violence of the explosion--laden with ammunition. On June 7th, on her way out of the Sea of Marmora, "E 11" sank a large troopship and so finished her cruise. I am quoting these statistics to point out what damage may be done by a single submarine on an army's line of communication. The moral effect (in such ways as delaying and scaring traffic) is, of course, as great as the material, and probably far greater. The Marmora submarines hardly deign to mention such small fry as dhows and other sailing ships, but the list runs to a great length when put together. Here are a few days' sinkings by "E 14" (Commander Boyle). On June 20th she sank three dhows, on the 22nd one, on the 23rd a two-masted sailing-ship, on the 24th two dhows, and on the 27th a brigantine.
