On 31 August 1940 a group of destroyers sailed from Immingham on a
mine-laying mission off the Dutch coast. The minelayers were from the 20th
Destroyer Flotilla and consisted of the destroyers HMS Express, HMS Esk,
HMS Icarus, HMS Intrepid and HMS Ivanhoe. The minelayers were escorted by
members of the 5th Destroyer Flotilla consisted of the destroyers HMS
Kelvin, HMS Jupiter and HMS Vortigern. Aireal reconnaissance detected a
German force and the ships of the 20th and 5th DF were ordered to
intercept, believing wrongly that the German ships were part of an invasion
force. HMS Express struck a mine and was badly damaged, HMS Esk went to her
assistance and hit mine and sank immediately, HMS Ivanhoe also went to her
assistance and hit a mine and was badly damaged, so much so she she had to
be sunk by HMS Kelvin. The following day they were joined by the light
cruisers HMS Aurora and HMS Galatea and while returning to base HMS Galatea
struck another mine and was slightly damaged off Cleaner Shoal Buoy near
the Humber light vessel.
