Her first appearance in our waters was on July 21st, when she bobbed up near Cape Cod, Mass., and attacked the tug _Perth Amboy_ and four barges in tow. Three torpedoes were fired at the tug, it was stated. A shell crashed through the wheelhouse, and cut off the hand of a sailor as he grasped the spokes of the steering wheel. The tug on fire, the German turned his attention to the barges, and kept firing away until several men were wounded and the helpless craft went down. Three women and five children were aboard the barges. They, with the crews, were reached by boats from Coast Guard Station No. 40, and landed at Nauset Harbor. Seaplanes from the Chatham naval air station flew to the scene and attacked the submarine, dropping aerial bombs. Though the haze obscured the view, bombs fell very near the U-boat, and one or two, it was reported, actually struck her but failed to explode. Not relishing this attack from the air, the German submerged and started for Canadian waters. Sinking a fishing schooner 60 miles southeast of Cape Porpoise, and burning another near the entrance to the Bay of Fundy, the raider turned her attention to the fishing fleet around Seal Island, Nova Scotia, sinking four American schooners and three Canadians. She also sank the Canadian tanker _Luz Blanca_ and the Swedish steamer _Sydland_. On August 11 the British steamship _Penistone_ was torpedoed and sunk, her master, David Evans, taken prisoner, and the _Herman Winter_, an American steamer, was attacked, but escaped uninjured. Sailing southward the U-boat, a week later, sank the _San Jose_, and Evans was released and allowed to get into a lifeboat with the Norwegian crew. The U-156 then went northward again, and on August 20 captured the Canadian steam trawler _Triumph_, and armed her as a raider, placing a German crew aboard. Operating together, they sank a dozen schooners in Canadian waters. Sinking the Canadian schooner _Gloaming_, on August 26, the U-156 started on her homeward voyage. The only attack she made returning was unsuccessful, an encounter on August 31 with the _U. S. S. West Haven_, which drove her off. Beginning by attacking barges and tugs, devoting most of her time to sinking small fishing craft, the U-156 met an inglorious end in the Northern Mine Barrage. Attempting to "run" the barrage, she struck a mine and sank so quickly that, apparently, many of her men did not have time to escape. Twenty-one survivors were landed on the Norwegian Coast; the fate of the rest of the crew is unknown. It seems like fate that this raider which destroyed so many helpless little American vessels should have been sent down by that creation which was mainly American, the great barrage which, 3,500 miles from this country, stretched across the North Sea.
