U-65 was a uboat designed and built for the German navy during ww1, and had a fairly successful career. Construction began in June 1915 and she was completed by March 1916. Between 1916 and Late October 1918 it sank a variety of vessels from armed yaughts and mine laying vessels to cargo vessels, before being scuttled by her crew at Pula in late October as the war was reaching the end.
