 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.
