In 1939–40, the army of France’s Third Republic – widely believed to be one of the strongest and best-equipped armed forces in the world – famously failed at both tasks and the result was one of the most ignominious catastrophes in military history. Due to the sudden collapse of France and the eviction of British military forces from the European continent, it appeared for a time as though the Second World War was virtually over before it had even begun in earnest. The historiography of the Second World War has not been kind to France. The sudden military collapse of the French Third Republic in June 1940 has left indelible images of evacuations, mass surrenders and a triumphant Hitler strutting in front of the Eiffel Tower in Paris. French defeat has often been regarded as the result of incompetent military leadership and battlefield cowardice by unmotivated troops, engendered by moral decay. After that humiliation, Charles de Gaulle’s 6 GNM_Case Red.layout.9.indd 6 04/08/2017 11:54 Introduction attempt to rally a Free French Army is regarded as a merely a footnote to history until American bayonets returned him to Paris in 1944. Seven decades later, the French contribution to the Allied war effort in the Second World War is still regarded as almost negligible. Many post-mortems have judged the French defeat to be virtually inevitable by focusing on internal political divisions within the Third Republic and the allegedly faulty state of military plans and preparations, although this was hardly apparent to contemporary senior leadership. Prior to its defeat in June 1940, the French Army enjoyed a strong international reputation. When Adolph Hitler ascended to power in Germany in 1933 and began to threaten the peace of Europe, it was Winston Churchill who famously said before the House of Commons, ‘Thank God for the French Army’, implying that it was a solid bulwark against aggression.2 Churchill’s admiration was based on the French Army’s demonstrated tenacity in the First World War. In September 1914, Général Ferdinand Foch had responded to the German push toward Paris with the quip, ‘My centre is giving way, my right is retreating, situation excellent – I am attacking’ and then launched a successful counter-offensive on the Marne. In 1916, when faced with a major German offensive at Verdun, Général Philippe Pétain had displayed the same kind of sang-froid, confidently stating ‘On les aura!’ (‘We shall have them’) and his deputy Général Robert Nivelle proclaimed ‘Ils ne passeront pas!’ (They shall not pass!). French rhetoric was matched by French bravery, demonstrated by Major Sylvain Raynal’s epic week-long defence of Fort Vaux. Individual positions were lost, but the French Army held and later retook all the lost ground in counter-attacks. Aside from Churchill, there were plenty of foreign observers who were impressed by the French Army’s resiliency in the First World War and this faith carried over into the post-war period. Although Britain’s strategy during the inter-war period was to avoid continental alliances and to focus instead on defence of its extended colonial empire, the leadership in London believed that French military power would continue to counter-balance any effort by Germany to alter the status 7 GNM_Case Red.layout.9.indd 7 04/08/2017 11:54 Case Red quo by force. As long as the French Army was strong and could prevent Germany from gaining control over the Channel ports, Britain did not need to maintain a strong army of its own for European contingencies. In April 1938, Churchill still confidently referred to the French Army as ‘the most perfectly trained and faithful mobile force in Europe’.3 When Hitler refused to be deterred from committing aggression against Poland, Neville Chamberlain’s government felt confident enough in France’s ability to anchor the defence of western Europe that it was willing to call Hitler’s bluff. Yet Chamberlain failed to appreciate that the French military had significant deficiencies and was unprepared to fight without significant help from Great Britain. If Chamberlain had better understood the amount of military assistance France would require just to survive an armed confrontation with the Third Reich, he would probably have hesitated to declare war upon Germany. After the Anglo-French declaration of war upon Germany, military professionals in both Paris and London noted some serious deficiencies in the French military, particularly the army’s heavy dependence upon poorly trained reservists and a lacklustre air force, but believed that these deficiencies would be ironed out soon after mobilization. When Paul Reynaud, France’s finance minister, proclaimed ‘Nous vaincrons parce que nous sommes les plus forts’ (We shall win because we are the strongest) in September 1939, he was believed in both Paris and London because, on paper, Anglo-French military and industrial resources did seem far superior to what Hitler’s Third Reich could muster. Yet during the winter of 1939/40, doubts began to appear in England, particularly with Churchill, that French military power had deteriorated.4 Lieutenant-General Alan Brooke, commander of II Corps of the British Expeditionary Force (BEF) in France, commented in his diary in November 1939, ‘I could not help wondering whether the French are still a firm enough nation to again take their part in seeing this war through.’5 Across the Rhine, Hitler regarded France as Germany’s mortal enemy and prepared for a new conflict almost from the start. Yet Hitler also respected the French Army – which he had fought against 8 GNM_Case Red.layout.9.indd 8 04/08/2017 11:54
