Hunting U-boats, going to the relief of vessels attacked, rescuing survivors, and later, when the convoy system was put into effect, escorting vessels--troop and supply ships, passenger steamers and merchantmen--through the danger zones to and from port, the destroyers had plenty to do. [Illustration: THE SURRENDER OF THE U-58 The crew of this submarine surrendered to the Fanning, after the destroyer's depth charges had disabled the undersea boat. Inset, the first officer of the U-boat, who traded his Iron Cross for a clean undershirt.] Finding a "sub" was the hardest part of the game, for the mere glimpse of a destroyer through a periscope was sufficient for the submarine to submerge and scurry away. Yet our vessels in European waters were credited with 256 attacks on U-boats, and there were not a few exciting encounters. [Illustration: CREW OF THE FANNING, WHICH SANK THE U-58 The star on the funnel indicates a submarine victim.] No more striking example of prompt action and quick results occurred during the entire war than that of the _Fanning_ and the _Nicholson_ when they "got" a German submarine, the U-58, on November 17, 1917. Sailing along with a convoy, at 4:10 p. m. Coxswain David D. Loomis, lookout on the _Fanning_, caught a glimpse of a periscope. It was a finger periscope, a tiny thing an inch and a half in diameter, no larger than a walking stick. It was lifted for only a few seconds, but the keen eyes of Loomis spied it, and he estimated its distance and location--three points on the port bow, 400 yards distant, moving across the bow at two knots' speed. The _Fanning_ headed for the spot, full speed, and as it crossed the course dropped a depth-bomb. Changing course, the _Nicholson_ was dashing across to drop another charge when the conning tower appeared. The _Nicholson_ headed for the submarine, and the _Fanning_ turned in her wake to attack. Dropping a depth-charge alongside the U-boat, the _Nicholson_ turned, firing from her stern gun. The sub's bow came up rapidly. She seemed to be down by the stern and was evidently badly damaged, but tried to right herself and increased her speed. As the _Nicholson_ cleared, the _Fanning_ opened fire with her bow gun. At the third shot the German crew came on deck, and held up their hands shouting, "Kamerad!" At 4:28 the submarine surrendered. It had been only 18 minutes since Loomis had sighted her periscope. Getting a line to the crippled craft, the destroyers prepared to take it in tow. But two of her crew disappeared for a moment. They scuttled the boat. As it sank, the Germans jumped into the water and swam for the _Fanning_. Heaving lines were thrown to them, and all but one, Franz Glinder, managed to get aboard. When it was seen that he was sinking, two of the _Fanning's_ crew, Chief Pharmacist's Mate Elzer Harwell and Coxswain Francis G. Connor, jumped overboard to rescue him. They got him aboard the ship, but in spite of all efforts to resuscitate him, he died.
