Rose Garden & the Cockleshell Heroes

Last updated on March 27th, 2024 at 12:52 pm

Rose Garden, Southsea, Portsmouth

Once upon a time, long, long ago, my parents took me to the Rex Cinema for a birthday treat.  It was a double bill of Reach for the Sky, the wartime story of RAF fighter pilot Douglas Bader, and The Cockleshell Heroes.  Having been brought up on feats of derring-do, it felt like being a kid in a sweet factory; or possibly a small boy in a cinema watching two war movies.  Youth doesn’t have the same kind of imagination that age gives us.  The Cockleshell Heroes, a fictional account of a real commando raid on France in 1942, held a particular interest, because the heroes were Royal Marines and trained in Portsmouth.  I knew Portsmouth, recognised several places in the film – and my grandfather had been a Royal Marine, based there.

Just near the Canoe Lake and esplanade in Portsmouth’s Victorian seaside suburb of Southsea, are the remains of Lumps Fort, a fortification dating back to the 19th century – at least.  Few people know it as that these days – it is now the Rose Garden and has been for decades.  This walled oasis of tranquillity with its formal paved walkways holds more rose bushes than you can shake a stick at, with in excess of 40 varieties.  When in bloom, it is stunning.  Pergolas offer shade round the edges and there are seating areas in old gun emplacements.

But in the dark days of 1942 it was where the Royal Marine Boom Patrol – a forerunner of the Special Boat Service (SBS) – trained.  These volunteers, so incredibly young, carried out what was really a suicidal mission to dislocate German military and other supplies by destroying ships in the occupied French port of Bordeaux.  The plan, brainchild of Major Herbert ‘Blondie’ Hasler,  was to paddle 6 two-man collapsible canvas kayaks, known as ‘cockles’ 70 miles up the Gironde river and fix magnetic mines – ‘limpets’ to the sides of likely-looking ships.

The mission, codenamed Operation Franklin set sail on the submarine HMS Tuna from Holy Loch on 30th November 1942.  On 7th December, 5 cockles were launched from Tuna, one having been damaged in action en route.  The ten young men set off across the open sea toward the Gironde, battling through the tidal races in the estuary – which resulted in the loss of two craft.  Paddling by night and laying up by day, two cockles reached Bordeaux and laid their mines.  One ship was sunk, four were damaged and the harbour facilities were disrupted for some considerable time.  Just two of the commandos survived – Hasler and his partner Bill Sparks: two of their colleagues died of hypothermia from capsizing in the tidal races; the other six were captured by the Germans and executed.  The ultimate achievements of the raid are unclear, though Churchill is reputed to have claimed that it shortened the war by six months.  Surely, he was being kind.

The film of the Cockleshell Heroes, starring Jose Ferrer, Trevor Howard and Anthony Newley, made in 1955

The film, made in 1955, stars Jose Ferrer, Trevor Howard and Anthony Newley.  It is fairly predictable stuff in many ways, though not without its moments; Newley is particularly awful.  The reality is that Franklin was an ill-conceived scheme, almost casually planned and based on inadequate intelligence.  The highly dangerous conditions in the Gironde estuary seem to have come as a surprise.  The lack of inter-service liaison and cooperation is just as damning.  SOE (Special Operations Executive) planned to attack the same target, and at the same time, but neither party had an inkling of the other’s plans.  The SOE raid was called off by its leader only when he heard the explosions in the harbour.  Nor was there any plan for the raiders to escape after planting their limpets – Hasler and Sparks got lucky and made it to Gibraltar with the help of French Resistance.  Those that approved Franklin condemned its brave participants to almost certain death.  I remember their untroubled faces staring up at me from photographs in a book I read once.

The full text of the plaque, at the entrance to the Rose Garden, reads:


This plaque, provided by Portsmouth City Council, was unveiled by Marine Bill Sparks DSM on 6th July 1992, in the presence of the Lord Mayor of Portsmouth, Councillor Jim Patey and the Chairman of the Leisure Committee Councillor Syd Rapson BEM, to mark the 50th Anniversary of this site which was used as a training base for the Royal Marine Boom Patrol Detachment, formed on 6th July 1942.  This secret unit trained on the Solent for raids by canoe (Cockles) on Europe.

The most famous raid was made on German shipping in Bordeaux docks on 11th December 1942 by ten members of RMBPD, only two of these Cockleshell Heroes returned:

MNE W SPARKS DSM                                 MNE J CONWAY
CPL  A LAVER                                               SGT S WALLACE
MNE W MILLS                                               MNE R EWART
CPL G SHEARD                                            MNE D MOFFAT

There are further plaques on the houses where the officers and men lived whilst training for the raid, at 9 Spencer Road and 27 Worthing Road.  The latter was a guest house known as White Heather, probably after the daughter of the house, Heather Powell.  She and Marine Robert Ewart fell in love; Bobby, from Glasgow, never made it back to her and she herself died shortly afterwards – it is said of a broken heart.

I gather there’s now a memorial to the Cockleshell heroes outside the Royal Marines Museum at Eastney, Portsmouth.  Something I need to look at next time I’m there.

A further memorial was unveiled in Birkenhead, home of Corporal Albert Frederick ‘Bert’ Laver, in December 2012, by Lord ‘Paddy’ Ashdown – himself an ex-marine and author of a book on the raid – A Brilliant Little Operation.

Corporal Laver was aged just 22 when he signed up for the top secret mission.  He visited a cousin at home before leaving.  They went to the pictures and he told her he thought he might not be coming back.

Hasler died in Glasgow in 1987; Bill Sparks died in Alfriston, East Sussex, in 2002.

The Royal Marine Boom Patrol Detachment also has its own memorial within the Allied Special Forces Grove at the National Memorial Arboretum in Staffordshire.  A wooden bench-like structure depicts one of the Cockleshell canoes used in Operation Frankton, and rests in a garden bed surrounded by ornamental grasses. The ‘canoe’ has name plates for each of the canoes used in the operation – Catfish, Crayfish, Cuttlefish, Coalfish, Conger and Cachelot.  Adjacent are memorials describing the mission and commemorating not only the Royal Marines but, also, the French nationals who assisted them.

  1. I saw the film on TV a couple of years ago. The film isn’t brilliant but it made me aware of the mission and the futility of it. Thank-you for this interesting post – I am glad I discovered your blog.

  2. I’d never heard this story before. I love that the old training facility has been planted with flowers and commemorates the bravery of the young men who carried out the mission. It’s sad they were so young, and almost surely sent out on a mission they couldn’t be expected to survive.

  3. Love the roses. I wish mine looked that good.
    As William stated above, I also didn’t know this part of history but I tend to not watch movies with Jose Ferrer in them (not a fan).
    That was enjoyable.
    Hope your day is blessed. ~:)
