to attack – these were all expressions of that blazing, explosive energy without which the vast machine, civilian as well as military, could not have been moved forward so steadily or steered through so many setbacks and difficulties’. Churchill conducted the affairs of his nation with a self-belief which was sometimes misplaced, but which offered an elixir of hope to those chronically troubled by rational fears. Amid Britain’s sea of troubles, he represented a beacon of warmth and humanity, as well as of will and supreme courage, for which most of even the most exalted and sceptical of his fellow countrymen acknowledged gratitude.
A widespread illusion persists that in 1940 Churchill broadcast constantly to the British people. In reality he delivered only seven speeches through the BBC between May and December, roughly one a month. But the impact of these was enormous upon a nation which in those days clung to its radio receivers as storm-bound sailors once lashed themselves to the masts of their ships. There were no advancing British armies to follow on the map, no fleets reporting victories. Instead the prime minister’s rolling periods, his invincible certainties in a world of raving tyrants, anchored his people and their island.
Few interventions of his own that summer were more significant than that which he made on 23 August, at the height of the perceived peril of German invasion. Britain’s threadbare defences were further denuded by the dispatch to Gen. Sir Archibald Wavell’s Middle East Command of 154 priceless tanks, to resist the anticipated Italian assault on Egypt. Besides the armour, forty-eight twenty-five-pounder guns, twenty Bofors, 500 Brens and 250 anti-tank rifles were sent. This was one of Churchill’s most difficult decisions of the war. Eden and Dill deserve credit for urging it, at first in the face of the prime minister’s doubts. It is impossible that they could have made such a commitment without a profound, almost perverse, belief that Hitler would not risk invasion – and perhaps also a recognition that Britain’s defence rested overwhelmingly on the Royal Navy and RAF rather than the army.
It is not surprising that an ignorant civilian such as ‘Chips’ Channon should have written on 16 September of expecting ‘almost certain invasion’. It is more remarkable that Britain’s military commanders and intelligence chiefs shared this fear, supposing that a massive German descent might take place without warning. Amphibious operations, opposed landings where port facilities are unavailable, do not require mere mechanical transfers of troops from sea to shore. They rank among the most difficult and complex of all operations of war. Two years of planning and preparation were needed in advance of the return to France of Allied armies in June 1944. It is true that in the summer of 1940 Britain lay almost naked, while four years later Hitler’s Atlantic Wall was formidably fortified and garrisoned. In 1940 Britain lacked the deep penetration of German wireless traffic which was attained later in the war, so that the chiefs of staff had only the patchiest picture of the Wehrmacht’s movements on the Continent.
Nonetheless it remains extraordinary that, at every suitable tide until late autumn, Britain’s commanders feared that a German army might arrive on the southern or eastern coast. The navy warned – though the prime minister disbelieved them – that the Germans might achieve a surprise landing of 100,000 men. The most significant enemy preparation for invasion was the assembly of 1,918 barges on the Dutch coast. Hitler’s military planners envisaged putting ashore a first wave of three airborne regiments, nine divisions – and 125,000 horses
– between Ramsgate and Lyme Bay, a commitment for which available shipping was wholly inadequate. Another serious problem, never resolved, was that the Wehrmacht’s desired initial dawn landing required an overnight Channel passage. It would be almost impossible to embark troops and concentrate barges without attracting British notice. The German fleet, never strong, had been gravely weakened by its losses in the Norwegian campaign. The defenders would be granted at least six hours of darkness in which to engage German invasion convoys, free from Luftwaffe intervention. The Royal Navy deployed around twenty destroyers at Harwich, and a similar force at Portsmouth, together with powerful cruiser elements. Channel invasion convoys would have suffered shocking, probably fatal losses. Once daylight came, German pilots had shown themselves much more skilful than those of the RAF and Fleet Air Arm in delivering attacks on shipping. The defending warships would have been badly battered. But for a German amphibious armada, the risk of destruction was enormous. The Royal Navy, outnumbering the German fleet ten to one, provided that decisive deterrent to Sealion.
The British, however, with the almost sole exception of the prime minister, perceived all the perils on their own side. Dill, the CIGS, seemed ‘like all the other soldiers…very worried and anxious about the invasion, feeling that the troops are not trained and may not be steady’. Brooke, as C-in-C Home Forces, wrote on 2 July of ‘the nakedness of our defences’. The Royal Navy was apprehensive that if German landings began, it might not receive adequate support from the RAF. Admiral Sir Ernle Drax, C-in-C Nore, expressed himself ‘not satisfied that…the co-operation of our fighters was assured’.
The service chiefs were justified in fearing the outcome if German forces secured a beachhead. Alan Brooke believed, probably rightly, that if invaders got ashore, Churchill would seek to take personal command of the ground battle – with disastrous consequences. In the absence of a landing, of course, the prime minister was able to perform his extraordinary moral function. The British generals’ fears of an unheralded assault reflected the trauma which defeat in France had inflicted upon them. It distorted their judgement about the limits of the possible, even for Hitler’s Wehrmacht. Churchill, by contrast, was always doubtful about whether the enemy would come. He grasped the key issue: that invasion would represent a far greater gamble than Germany’s 10 May attack in the West. Operation Sealion could not partially succeed. It must achieve fulfilment, or fail absolutely. Given Hitler’s mastery of the Continent, and the impotence of the British Army, he had no need to stake everything upon such a throw.
But the prime minister was committed body and soul to prosecution of the war. In the summer and autumn of 1940, preparing a defence against invasion was not merely essential, it represented almost the only military activity of which Britain was capable. It was vital to incite the British people. If they were allowed to lapse into passivity, staring fearfully at the array of German might, allconquering beyond the Channel, who could say whether their will for defiance would persist? One of Churchill’s great achievements in those months was to convince every man and woman in the country that they had roles to play in the greatest drama in their history, even if the practical utility of their actions and preparations was often pathetically small. Young Lt. Robert Hichens of the Royal Navy wrote: ‘I feel an immense joy at being British, the only people who have stood up to the air war blackmail.’
Between 24 August and 6 September the Luftwaffe launched 600 sorties a day. British civilians were now dying in hundreds. Devastation mounted remorselessly. Yet 7 September marked the turning point of the Battle of Britain. Goering switched his attacks from the RAF’s airfields to the city of London. A sterile debate persists about whether Britain or Germany first provoked attacks on each other’s cities. On 25 August, following civilian casualties caused by Luftwaffe bombs falling on Croydon, Churchill personally ordered that the RAF’s Bomber Command should retaliate against Berlin. Some senior RAF officers resisted, on the grounds that such an attack, by the forces available, could make little impact and would probably incite the Germans to much more damaging action against British urban areas. Churchill overruled them, saying: ‘They had bombed London, whether on purpose or not, and the British people and London especially should know that we could hit back. It would be good for the morale of us all.’ Some fifty British bombers were dispatched to Berlin, and a few bombs fell on the city. Though the material damage was negligible, the Nazi leadership was indeed moved to urge a devastating response against
