Mines laid by UC-14 in her 38 patrols were credited with sinking 16 ships, one of which was the Italian pre-dreadnought battleship Regina Margherita, which at 13,427 tonnes displacement was one of the largest ships sunk by U-boats during the war. UC-14 was mined and sunk on 3 October 1917.

She was surrendered on 24 November 1918 and broken up at Preston in 1919–20.

UC-66 was sunk by HM seaplane No. 8656, a Curtiss Model H-12, off the Isles of Scilly on 27 May 1917. The wreck was found by divers in 2009. This is a notable early aircraft success against a U-boat.

On 18 October 1918, U-34 sailed for the last time, disappearing with all 38 crew members lost. Although it was claimed that she was depth charged and sunk near Gibraltar by HMS Privet on 9 November 1918, it is believed that the U-boat had been lost prior to that, but it has never been confirmed one way or the other.
