In the second week of December, Eugène Samuel went to the little town of Pont-en-Royans, whose ancient houses cling impossibly to the vertical sides of the Gorges de la Bourne, guarding the narrow bridge which spans the river and the western entry to the plateau. Here he knocked on the door of one of his brothers-in-law, the café owner and town Mayor Louis Brun, and asked if he could help. Brun said he knew just the place.
On 17 December 1942, Brun, accompanied by Simon, Samuel’s younger brother, struggled through deep snow to look at an isolated farmhouse with substantial outbuildings called La Ferme d’Ambel, which lay in a desolate and deserted valley in the south-western corner of the plateau. It was ideal. The farm, fed by a bountiful and permanently running spring, is tucked under a high ridge covered in woods, which sweep down almost to its back door. The main access for vehicles is by a rough track served by stone bridges, leading down through beechwoods which shield the area from the nearby mountain road. The house, together with the loft space above and its outbuildings, was capable of accommodating, the two men estimated, around fifty or so réfractaires.
To add to its advantages the Ferme d’Ambel lay at the heart of a large timber concession centred on the nearby Ambel forest, which provided good cover for human activity in the area – indeed the réfractaires could be employed as a useful local labour force. These timber concessions played an important part in the life (and especially black-market life) of wartime France. Timber produced charcoal and charcoal produced the gas which, in the absence of readily available petrol, was the main driving power of the gazogène lorries and cars which could be seen everywhere puffing and wheezing around the streets of Grenoble and struggling their way in a cloud of smoke up the steep roads of the plateau. It was for this reason that timber concessions were often closely linked with the haulage industry – and so it was with the concession at the Ambel forest, two of whose most active partners were members of the transport firm run by the three Huillier brothers who had helped to found the Villard-de-Lans group of early resisters.
On 6 January 1943, a dozen or so young men, made up chiefly of railway workers and Polish refugees from Villard, moved into the Ambel farm. That month, as the pressure of conscription grew, a clandestine system was established to deal with the increasing flood of young men seeking refuge from the transports to Germany. Would-be réfractaires would be asked to go to a hardware shop, run by two sympathizers just a couple of hundred metres from the Place Verdun in Grenoble. The shop was served by two entrances, one on the main street and a second leading on to a small street at the rear. Here, in a back room, they were interviewed by Eugène Chavant and, if found acceptable, were instructed to go home, pack a few necessaries in a rucksack and catch the little funicular railway run by the Huillier brothers to Villard-de-Lans. There they would transfer to a Huillier bus to Pont-en-Royans where they would go to Louis Brun’s restaurant. From here they were guided across the mountains at night to Ambel. On arrival, they would be met by the site director of the Ambel forestry concession, Louis Bourdeaux, who had been appointed by the Villard group as the Ambel’s camp commander.
Measures were also put in train to make Ambel as secure as possible. The lights in the Ferme d’Ambel, which depended on a single electric cable supplied from the hydroelectric plant at Pont-en-Royans, were left on all day and night. This enabled a Resistance sympathizer at the plant to warn of approaching danger by turning the supply (and therefore Ambel lights) on and off three times in quick succession. Ambel was now a properly structured Maquis camp. Some claim that it was the first to be established in all France.
Meanwhile, at Côtes-de-Sassenage, Pierre Dalloz was thinking of ways to pursue his own ideas about the use of the Vercors to fight back against France’s occupiers. Encouraged by Jean Lefort’s welcome for his plan (but still completely unaware of the existence of his co-conspirators in Grenoble and Villard-de-Lans), he decided to take matters further. He was advised by a left-wing friend at Grenoble University that the man to see was Yves Farge, the foreign affairs editor of the regional newspaper Progrès de Lyon, who was known to have high-level Resistance connections.
In late January 1943, Dalloz, with his plan carefully tucked into an inside pocket of his jacket, took the train to Lyon, calling a little after midday at the offices of Progrès where he asked for the foreign affairs editor. The two men went to a nearby restaurant, where over lunch Dalloz explained his idea. He left a copy of his paper with Farge, who expressed enthusiasm for the plan and promised to ensure that it would be seen by the ‘appropriate people’. Farge must have briefed Jean Moulin very shortly after the lunch, for on 29 January Moulin sent a courier to de Gaulle in London with full details of the Dalloz plan and a personal recommendation that it should be supported.
On 31 January, Farge paid Dalloz a return visit in Grenoble to tell him that Moulin had seen the plan, approved it and agreed that 25,000 francs should now be assigned to Dalloz to develop the idea. Dalloz hurriedly typed a second, more comprehensive paper on his ideas. A few days later, he received a note which instructed him to join Farge and to ‘Be in the waiting room at Perrache station in Lyon at 12h15 on 10 February where “Alain” will meet you.’ The two men found their contact ‘Alain’ in deep contemplation of the window display of the station bookshop. ‘The meeting place has been changed,’ he instructed. ‘Someone will be waiting for you at Bourg-en-Bresse station. There is a train at 16h20. When you arrive, stand in front of the station entrance and carry a copy of the newspaper Signal in a prominent place. General “Vidal” will approach you. He will be dressed in a grey overcoat with a white silk handkerchief displayed in the top pocket.’
The two men did not have to stand long outside the station entrance before they saw, in the light of a street lamp, a rather small man with a brisk military step displaying a most luxurious silk white handkerchief, which fluttered in the wind from his top pocket. After introductions, the old soldier led them away from the station, turning left into the main street of Bourg-en-Bresse and, 200 metres further on, passing a cake shop whose éclairs Dalloz remembered with great affection from his youth. The General stopped in front of the next-door building, a three-storey turn-of-the-century terraced town house. Here he took a step back to get a better look, as though checking he was in the right place, and then fumbled with his key for a moment in the lock of the heavy oak front door before it opened. Inside, the General lit a match to find the switch and turned the lights on. They were in a large room with closed shutters which turned out to be the offices of an insurance company. A moment later they were joined by a fourth, older man with a magnificent white moustache who introduced himself as General ‘Richard’.
In fact, the two civilians were in the presence of the two most important military officers in the hierarchy of the Secret Army in France: the man de Gaulle had charged with heading up the Resistance’s military wing, Charles Delestraint and his deputy General Desmazes. Dalloz ran through his three-page report, a copy of which he gave to Delestraint, together with an annotated map of the Vercors, a guidebook of the plateau and several supporting photographs. After asking Dalloz some searching questions, Delestraint pronounced his verdict: ‘From now on the Vercors will be part of the national military plan for liberation. From today it will be known as the Plan Montagnards.’
Two days later, on the moonlit night of 12/13 February 1943, two Lysander light aircraft from the RAF’s 161 Squadron landed in a field near Ruffey-sur-Seille in the Jura. Here they picked up Jean Moulin and Charles Delestraint, who carried a briefcase containing Dalloz’s papers, maps and photos for Plan Montagnards, and flew them back to Britain. During his stay in London, Delestraint had several meetings with de Gaulle at which he discussed his plans for the Secret Army, including in the Vercors. Afterwards, according to de Gaulle, Delestraint ‘was able to work usefully with the Allied leaders. Thereby,
