U-65. Kaptlt. Hermann von Fischel. On completion at Kiel did trials at Kiel School about May and June 1916, afterwards proceeding to the North Sea to join 4th Flotilla.
? 11–14 July 1916. North Sea patrol.
16–24 July 1916. North Sea patrol.
17–21 August 1916. North Sea patrol, attacked minesweeperHaldon 20 August.
3–4 September 1916. North Sea patrol. Returned with defects.
28 November – 7 December 1916. Left Cattaro and on 1 December probably sank a steamer. On 4 December sank British SS Caledonia in 35°40′N17°04′E / 35.667°N 17.067°E / 35.667; 17.067. The submarine was badly rammed by Caledonia and appears to have returned home immediately on the surface.
17 February 1917. Sank troopship SS Athos (12,644 tons). 754 casualties.
29 March – 19/20 April 1917. In western Mediterranean sank 4 steamships, 5 sailing vessels (13,000 tons).
The next cruise of U-65 which can be reconstructed with probability was from 10 to 31 January or 1 February 1918. On this cruise she sank 2 steamers and 1 sailing vessel, and was twice attacked from the air and once by depth-charged by Campanula, which she missed by torpedo.
A later possible cruise was for about the first 3 weeks of September 1918, on which she sank 4 steamers and damaged 4 more, between longitudes 8° and 17°E.
At the end of October 1918 she was scuttled[9] by the Germans at Pola or Cattaro.

^NA, HW 7/3, p.230, states U-65 was "blown up". Handelskrieg, Vol 5, p.227, names 10 submarines, including U-65, which were all in a state beyond repair and were destroyed at the evacuation of the Austrian submarine bases: "... some of them were blown up in their bases, some were scuttled at sea in the vicinity of their bases." Uboat.net says she was "scuttled", but gives no source or reference for this.
