Gemişi=During her trials, UB-7 developed a leak which took some time to repair. In the meantime, she was assigned the Austrian number of U-7 and an Austrian commander.Her German crew at Pola—since it was still the intent for UB-7 to be transferred to the K.u.K. Kriegsmarine—wore either civilian clothes or Austrian uniforms.As time dragged on, the Austrian U-3 and U-4 were still not ready,and eventually Admiral Anton Haus, the head of the Austrian Navy, reneged on his commitment because of the overt hostility from neighbor and former ally Italy.With the change of heart from the Austrians, Germany resolved to retain UB-7 and send her to the aid of the Turks.So, upon completion of her leak repairs, the boat was commissioned into the German Imperial Navy as SM UB-7 on 6 May under the command of Oberleutnant zur See Wilhelm Werner,a 26-year-old native of Apola.At commissioning, the boat temporarily joined the Pola Flotilla (German: Deutsche U-Halbflotille Pola).Because of her limited range, UB-7 would not have been able to make the entire journey to Turkey, so on the night on 15/16 May, she was towed by the Austrian destroyer SMS Triglav through the Straits of Otranto and into the Ionian Sea.By June,UB-7 had reached Smyrna—not having any success on her journey there—and joined U-21 and UB-8 in the Constantinople Flotilla (German: U-boote der Mittelmeer division in Konstantinopel).Once there, UB-7 was ineffective because she was hampered by her limited torpedo supply and her weak engines, which made negotiating the strong Dardanelles currents nearly impossible.Because of this, UB-7 was sent to patrol in the Black Sea in July, cruising without success from the 5th to the 22nd.In September 1915, UB-7 and UB-8 were sent to Varna, Bulgaria, and from there, to patrol off the Russian Black Sea coast. On 18 September, UB-7 torpedoed and sank the British steamer Patagonia about 10.5 nautical miles (19.4 km) from Odessa.The cargo ship, of 6,011 gross register tons (GRT), was the only ship credited to UB-7,and the only one sunk by any of the Constantinople Flotilla in the month.Because Bulgaria had joined the Central Powers, battleships of the Russian Black Sea Fleet, and aircraft from the seaplane carriers Almaz and Imperator Nikolai I began attacks on Varna and the Bulgarian coast on 25 October. UB-7 and UB-8, both based out of Varna by this time, sortied to disrupt the bombardment.Off Varna on the 27th, UB-7 got in position to fire a torpedo at the Russian battleship Panteleimon (most well-known under her former name of Potemkin). Although UB-7's crew heard what they thought was the torpedo explode, it did not hit Panteleimon. Despite the lack of success, the attempt did cause the Russians to break off their attacks and withdraw.In early 1916, UB-7 and UB-8 were still cruising in the Black Sea out of Varna.The Germans did not have good luck in the Black Sea, which was not a priority for them.The Bulgarians, who saw the value of the submarines in repelling Russian attacks, began negotiations to purchase UB-7 and UB-8.Bulgarian sailors practiced in the pair of boats and technicians were sent to Kiel for training at the German submarine school there.The transfer of UB-8 to the Bulgarian Navy took place on 25 May 1916,but for reasons unreported in sources, UB-7 remained under the German flag.In July 1916, the Germans sent SMS Breslau to mine off Novorossisk.To attempt to neutralize any Russian response, UB-7—under the command of Hans Lütjohann, who had taken over for Werner when he returned to Germany to command the new U-55 was stationed off Sevastopol to attack any ships that sailed in response to the mission.Unfortunately, Russian seaplanes spotted UB-7 and bombed the U-boat, preventing her from accomplishing her goal. With the submarine out of the way, Rear Admiral Aleksandr Kolchak sortied with dreadnought Imperatritsa Mariya, cruiser Kagul, and five destroyers. The Russian fleet engaged Breslau, which was forced to abort her mission and retire. Sources are quiet on damage, if any, suffered by UB-7.On 27 September 1916, UB-7 departed Varna for operations off Sevastopol and was never heard from again.According to some sources, UB-7 was mined somewhere in the Black Sea.In June 1917, a Russian pilot captured by the Germans reported that a Russian airplane bombed and sank UB-7 on 1 October at position 44°30′N 33°15′E ,near the Chersones Lighthouse.Authors Dwight Messimer and Robert Grant are each dubious of this claim,and the fate of UB-7 is still officially unknown.Among the fifteen men lost on UB-7 were the Constantinople Flotilla's senior radio officer,and the first Bulgarian submariner lost during the war, a trainee from Vidin.
