unsophisticated French codes. Exasperation within the Special Operations Executive, especially after the massive Gestapo infiltration of the Resistance the year before, prompted the chief SOE cryptographer, Leo Marks, to go round to the Gaullists’ office in Duke Street in central London. He asked their cipher officers to encode any message they wanted, then he took it from them and broke it ‘under their astonished noses’. ‘This did not endear the British to the French,’ wrote the official historian with dry understatement. Yet Gallic pride still prevented the Free French from using British or American code systems. Just before D-Day, ‘C’, the head of the Secret Intelligence Service, warned the Prime Minister that the French must not be allowed to send any messages by radio, only by secure landlines.
Churchill sent two York passenger aircraft to Algiers to bring back de Gaulle and his retinue. But de Gaulle was reluctant to come, because Roosevelt would not permit a discussion on French civil government. Churchill’s representative, Duff Cooper, argued with him for an hour on 2 June, trying to persuade him to back off from this brinkmanship. If de Gaulle refused to come, then he would be playing into Roosevelt’s hands, Duff Cooper told him. He should be present in England in his role as military leader. Above all, Duff Cooper warned him, he would finally lose the regard of the Prime Minister, who would decide that he was an impossible man to deal with. De Gaulle agreed only the next morning, when the two Yorks were already waiting for them on the airfield to take them on the first leg of the journey to Rabat in French Morocco.
After flying through the night from Rabat, de Gaulle’s plane touched down at exactly 06.00 hours on 4 June at Northolt. After all the secrecy imposed on their journey, Duff Cooper was surprised to find a large guard of honour drawn up and an RAF band playing the ‘Marseillaise’ as they descended the steps. A very Churchillian letter of greeting was handed to de Gaulle. ‘My dear General de Gaulle,’ it read. ‘Welcome to these shores! Very great military events are about to take place.’ He invited him down to join him on his personal train. ‘If you could be here by 1.30 p.m., I should be glad to give you dejeuner and we will then repair to General Eisenhower’s headquarters.’
Duff Cooper was mystified by the notion of Churchill’s ‘advance headquarters’ on a train, which they finally found in a siding at a small station near Portsmouth. He considered it ‘a perfectly absurd scheme’. His heart sank much further when he found that Field Marshal Smuts, the decidedly Francophobe South African, was in the Prime Minister’s entourage. Then Churchill opened the conversation with de Gaulle by saying that he had brought him over to deliver a speech on the radio. To make matters even worse, he made no mention of discussing civil affairs in France, the subject of greatest interest to de Gaulle.
When Anthony Eden, the Foreign Secretary, turned the conversation to ‘politics’, which basically meant Roosevelt’s continued refusal to recognize de Gaulle and his provisional government, de Gaulle’s anger erupted. His resentment was inflamed by the Allied currency printed in the United States and issued to their troops. He said that this currency, which he considered ‘ une fausse monnaie ’, was ‘absolutely unrecognized by the government of the Republic’. This was an important point which does not appear to have occurred either to the American authorities or to the British. If no government was prepared to back these rather unimpressively printed banknotes - American troops compared them to ‘cigar coupons’ - then they were worthless.
Churchill flared up, demanding how the British could act separately from the United States. ‘We are going to liberate Europe, but it is because the Americans are with us. So get this quite clear. Every time we have to decide
