'Quixote' was the British part of the operation to cut the telephone cables connecting the UK and German-occupied Norway via Borkum in Germany (18 and 28 May 1940).

The British ends of the cables were at Lowestoft, Baton and Mundesley. Only two of the cables were cut on the operation’s first night, and the third on 28 May. The naval force involved was the same as that later used in 'Quentin' (i), namely the the destroyers Gallant, Jackal, Jaguar and Javelin screening the minesweeping trawlers Cape Melville, Grampian, James Lay, Milford Princess, Milford Queen and Pelton.
