HMS Charybdis and HMS Limbourne
Four-hundred and sixty-nine men died when two Royal Navy Cruisers, HMS Charybdis and HMS Limbourne were hit by German torpedoes in October 1943. Twenty-one bodies later washed ashore in Guernsey and were buried with full military honours.
Services in Guernsey have been held every year since 1947, with the island marking the 80th anniversary this year.
The service will be held at the Foulon Cemetery and attended by His Excellency as well as the Bailiff Sir Richard McMahon and veterans of the Royal Navy, Royal Marines and other services.
Wreaths will be laid by members of the various island organisations and the Dean of Guernsey, the Very Reverend Tim Barker will lead the service.
His Excellency and his ADC, Major Marco Ciotti will also attend the Annual Memorial Dinner held at Les Cotils on 22nd September
