"SOS," came the distress call from the _Dunraven_, "Shelled by submarine." The _Noma_ had just finished repairing one of her boilers, but she put on all steam and headed for the scene. As she came up, the vessel, torpedoed, seemed to be sinking. The submarine, which was close to the steamer, was still shelling her. The _Noma_ headed for the U-boat, attempting to ram her, but she submerged and the yacht dropped depth-bombs around the spot. Then she turned attention to the _Dunraven_. This decoy ship, commanded by Captain Gordon Campbell, most noted of "Q-boat" captains, had pursued its usual tactics when the "sub" was sighted, part of the crew, disguised as merchant sailors, taking to the lifeboats, leaving hidden aboard the gunners ready to fire shells or torpedo when the submarine ventured nearer. But this time the U-boat got the best of it. One of its shells struck the steamer and blew up a depth-bomb. Two more shots landed, and set the ship afire. The flames swept down to where ammunition, shells and torpedoes were piled, and they exploded, hurling gun and gun-crew into the air. Then came the torpedo, which as it hit the ship caused another big explosion. But the _Dunraven_ fought on, and it was only after she had fired two torpedoes at the "sub," and many of her crew were wounded, that she sent out the distress call. The "sub" driven off, the _Noma_ circled the vicinity, keeping a sharp lookout for the enemy. Two British destroyers arrived shortly afterward, and with the _Noma_ rescued the decoy-ship's crew. One of them, the _Christopher_, took the _Dunraven_ in tow, the _Noma_ acting as escort until the next day, when she was relieved by a French destroyer. But the _Dunraven_ was too badly damaged to remain afloat, and sank before she reached port. Our forces in French waters were reinforced in August and September by nineteen more vessels, these being: Second Patrol Division, Commander F. N. Freeman--_Alcedo_, (Lieutenant Commander W. T. Conn); _Remlik_, (Lieutenant Commander I. C. Johnson); _Wanderer_, (Lieutenant Commander P. L. Wilson); _Guinevere_, (Lieutenant Commander Guy Davis); _Corona_, (Lieutenant Commander L. M. Stevens); _Carola_, (Lieutenant Commander H. R. Keller); and the _Emeline_, (Lieutenant Commander R. C. Williams). Third Division, Captain T. P. Magruder--_Wakiva_, (Lieutenant Commander T. R. Kurtz), armed yacht; _Anderton_, (Boatswain H. Miller); _Cahill_, (Lieutenant A. E. Wills); _Rehoboth_ and _McNeal_, (Lieutenant C. N. Hinkamp); the _Lewes_, _James_, _Douglas_, _Bauman_, _Courtney_, and _Hinton_, (Lieutenant A. McGlasson), mine-sweepers; _Bath_, supply ship.
