A memorial has been unveiled in Hampshire to the heroes of one of the Second World War's most daring and gruelling raids.

The ceremony marked the upcoming 70th anniversary of Operation Frankton, when the so-called Cockleshell Heroes were sent to the Nazi-occupied harbour of Bordeaux to bomb ships.

Of the 12 Royal Marines who set out on the mission, only two came back alive, the rest falling victim to German forces or hypothermia. But the operation was deemed a success, with Winston Churchill saying that he believed it shortened the war by six months.

Those heroes were honoured as Lord Paddy Ashdown, a former member of the Special Boat Service, unveiled the memorial at the Royal Marines Museum in Southsea, Hampshire.
