• 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′N 17°04′E. 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).
• 14 May – 9 June 1917. Possible cruise of U-65. After leaving Cattaro submarine damaged cruiser HMS Dartmouth by torpedo on 15 May in 41°11′N 18°15′E. She then sank 7 steamers and 12 sailing vessels in the central Mediterranean. 6 June, she was reported off Cape Passaro, 7 June in the vicinity of Straits of Messina, and 8 June was possibly attacked by seaplane in 39°4′N 19°00′E.
• 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.
