Lieutenant-Commander Steven Mackenzie, who has died aged 95, played a notable part in the covert operations of the Inshore Patrol Flotilla for the Secret Intelligence Service and SOE; he subsequently served with MI6 in Europe, the Far East and Latin America.
In March 1942, at Falmouth, Mackenzie took command of Le Dinan, usually known by its registration number, N51, a 65ft Concarneau fishing trawler, with Lewis guns mounted amidships and a crew of eight. The mission (code-named “Marie Louise”) was to extricate Colonel Rémy and bring him and his wife and children back to England under the noses of the Gestapo who were hunting them.
Rémy was the field name of Col Gilbert Renault, head of the Confrérie de Notre Dame, which was to become one of the most important of all the Free French intelligence networks in enemy-occupied France.
At a secluded anchorage at New Grimsby in the Scilly Isles, the hull, bulwarks, deckhouse and masts of N51 forsook their naval grey and were repainted in shades of green and brown. A registration number, a Breton name and French flags on either bow were added. Sten guns, pistols and grenades were put aboard, and revolver and small arms practice shoots were held on the shore.
After several failed attempts, the party sailed in June 1942. Mackenzie’s First Officer was Daniel Lomenech, a Frenchman who knew the Breton coastline well. They had an RAF escort until they were half way across the Channel, but there followed three nerve-racking hours of unescorted sailing before dark, crossing an area forbidden to fishing vessels; a sighting by a German air patrol would mean an attack.
