I would be grateful to receive for the help and advice of forum members regarding how I can confirm the longitude and latitude of the wreck of HMS Isis. The ship was sunk by a mine whilst it was on patrol in the English Channel. My Google searches have return two different locations. HMS Isis (D87) - Wikipedia Isis struck a mine and sank on 20 July 1944 at the position 49°27′N 0°41′W in channel 'T' off the western sector of the Normandy landing beaches. HMS Isis (D 87) of the Royal Navy - British Destroyer of the I class - Allied Warships of WWII - uboat.net The wreck is in 20 meters of water about 5 miles North-East of Courseulles-sur-Mer, Normandy in position 49.27.196N, 00.36.574W. Sadly neither cites a reference for their respective co-ordinates. Many thanks.
trying to find exact confirmation, found this in Admiralty War Diaries, unfortuanately no “exact” location
