Interruptions caused by the enemy’s air forces, long-range artillery and light naval forces have, for the first time, assumed major significance. The harbors at Ostend, Dunkirk, Calais and Boulogne cannot be used as night anchorages for shipping because of the danger of English bombings and shelling. Units of the British Fleet are now able to operate almost unmolested in the Channel. Owing to these difficulties further delays are expected in the assembly of the invasion fleet.
The next day matters grew worse. British light naval forces bombarded the chief Channel invasion ports, Ostend, Calais, Boulogne and Cherbourg, while the R.A.F. sank eighty barges in Ostend Harbor. In Berlin that day Hitler conferred with his service chiefs at lunch. He thought the air war was going very well and declared that he had no intention of running the risk of invasion.24 In fact, Jodl got the impression from the Fuehrer’s remarks that he had “apparently decided to abandon Sea Lion completely,” an impression which was accurate for that day, as Hitler confirmed the following day—when, however, he again changed his mind.
Both Raeder and Halder have left confidential notes of the meeting of the Fuehrer with his commanders in chief in Berlin on September 14.25 The Admiral managed to slip Hitler a memorandum before the session opened, setting forth the Navy’s opinion that
the present air situation does not provide conditions for carrying out the operation [Sea Lion], as the risk is still too great.
At the beginning of the conference, the Nazi warlord displayed a somewhat negative mood and his thoughts were marred by contradictions. He would not give the order to launch the invasion, but neither would he call it off as, Raeder noted in the Naval War Diary, “he apparently had planned to do on September 13.”
What were the reasons for his latest change of mind? Halder recorded them in some detail.
A successful landing [the Fuehrer argued] followed by an occupation would end the war in a short time. England would starve. A landing need not necessarily be carried out within a specified time … But a long war is not desirable. We have already achieved everything that we need.
British hopes in Russia and America, Hitler said, had not materialized. Russia was not going to bleed for Britain. America’s rearmament would not be fully effective until 1945. As for the moment, the “quickest solution would be a landing in England. The Navy has achieved the necessary conditions. The operations of the Luftwaffe are above all praise. Four or five days of decent weather would bring the decisive results … We have a good chance of bringing England to her knees.”
What was wrong, then? Why hesitate any longer in launching the invasion?
The trouble was, Hitler conceded:
The enemy recovers again and again … Enemy fighters have not yet been completely eliminated. Our own reports of successes do not give a completely reliable picture, although the enemy has been severely damaged.
On the whole, then, Hitler declared, “in spite of all of our successes the prerequisite conditions for Operation Sea Lion have not yet been realized.” (The emphasis is Halder’s.)
Hitler summed up his reflections.
1. Successful landing means victory, but for this we must obtain complete air superiority.
2. Bad weather has so far prevented our attaining complete air superiority.
3. All other factors are in order.
Decision therefore: The operation will not be renounced yet.
Having come to that negative conclusion, Hitler thereupon gave way to soaring hopes that the Luftwaffe might still bring off the victory that so tantalizingly and so narrowly continued to evade him. “The air attacks up to now,” he said, “have had a tremendous effect, though perhaps chiefly on the nerves. Even if victory in the air is only achieved in ten or twelve days the English may yet be seized by mass hysteria.”
To help bring that about, Jeschonnek of the Air Force begged to be allowed to bomb London’s residential districts, since, he said, there was no sign of “mass panic” in London while these areas were being spared. Admiral Raeder enthusiastically supported some terror bombing. Hitler, however, thought concentration on military objectives was more important. “Bombing with the object of causing a mass panic,” he said, “must be left to the last.”
Admiral Raeder’s enthusiasm for terror bombing seems to have been due mainly to his lack of enthusiasm for the landings. He now intervened to stress again the “great risks” involved. The situation in the air, he pointed out, could hardly improve before the projected dates of September 24–27 for the landing; therefore they must be abandoned “until October 8 or 24.”
But this was practically to call off the invasion altogether, as Hitler realized, and he ruled that he would hold up his decision on the landings only until September 17—three days hence—so that they still might take place on September 27. If not feasible then, he would have to think about the October dates. A Supreme Command directive was thereupon issued.
Berlin
September 14, 1940
TOP SECRET
… The Fuehrer has decided:
The start of Operation Sea Lion is again postponed. A new order follows September 17. All preparations are to be continued.
The air attacks against London are to be continued and the target area expanded against military and other vital installations (e.g., railway stations).
Terror attacks against purely residential areas are reserved for use as an ultimate means of pressure.26
Thus though Hitler had put off for three days a decision on the invasion he had by no means abandoned it. Give the Luftwaffe another few days to finish off the R.A.F. and demoralize London, and the landing then could take place. It would bring final victory. So once again all depended on Goering’s vaunted Air Force. It would make, in fact, its supreme effort the very next day.
The Navy’s opinion of the Luftwaffe, however, grew hourly worse. On the evening of the crucial conference in Berlin the German Naval War Staff reported severe R.A.F. bombings of the invasion ports, from Antwerp to Boulogne.
… In Antwerp … considerable casualties are inflicted on transports—five transport steamers in port heavily damaged; one barge sunk, two cranes destroyed, an ammunition train blown up, several sheds burning.
The next night was even worse, the Navy reporting “strong enemy air attacks on the entire coastal area between Le Havre and Antwerp.” An S.O.S. was sent out by the sailors for more antiaircraft protection of the invasion ports. On September 17 the Naval Staff reported:
The R.A.F. are still by no means defeated: on the contrary they are showing increasing activity in their attacks on the Channel ports and in their mounting interference with the assembly movements.*27
That night there was a full moon and the British night bombers made the most of it. The German Naval War Staff reported “very considerable losses” of the shipping which now jammed the invasion ports. At Dunkirk eighty-four barges were sunk or damaged, and from Cherbourg to Den Helder the Navy reported, among other depressing items, a 500-ton ammunition store blown up, a rations depot burned out, various steamers and torpedo boats sunk and many casualties to personnel suffered. This severe bombing plus bombardment from heavy guns across the Channel made it necessary, the Navy Staff reported, to disperse the naval and transport vessels already concentrated on the Channel and to stop further movement of shipping to the invasion ports.
Otherwise [it said] with energetic enemy action such casualties will occur in the course of time that the execution of the operation on the scale previously envisaged will in any case be problematic.28
It had already become so.
In the German Naval War Diary there is a laconic entry for September 17.
The enemy Air Force is still by no means defeated. On the contrary, it shows increasing activity. The weather situation as a whole does not permit us to expect a period of calm … The Fuehrer therefore decides to postpone “Sea Lion” indefinitely.29
The emphasis is the Navy’s.
Adolf Hitler, after so many years of dazzl
ing successes, had at last met failure. For nearly a month thereafter the pretense was kept up that the invasion might still take place that autumn, but it was a case of whistling in the dark. On September 19 the Fuehrer formally ordered the further assembling of the invasion fleet to be stopped and the shipping already in the ports to be dispersed “so that the loss of shipping space caused by enemy air attacks may be reduced to a minimum.”
But it was impossible to maintain even a dispersed armada and all the troops and guns and tanks and supplies that had been assembled to cross over the Channel for an invasion that had been postponed indefinitely. “This state of affairs,” Halder exclaimed in his diary September 28, “dragging out the continued existence of Sea Lion, is unbearable.” When Ciano and Mussolini met the Fuehrer on the Brenner on October 4, the Italian Foreign Minister observed in his diary that “there is no longer any talk about a landing in the British Isles.” Hitler’s setback put his partner, Mussolini, in the best mood he had been in for ages. “Rarely have I seen the Duce in such good humor … as at the Brenner Pass today,” Ciano noted.30
Already both the Navy and the Army were pressing the Fuehrer for a decision to call off Sea Lion altogether. The Army General Staff pointed out to him that the holding of the troops on the Channel “under constant British air attacks led to continual casualties.”
Finally on October 12, the Nazi warlord formally admitted failure and called off the invasion until spring, if then. A formal directive was issued.
Fuehrer’s Headquarters
October 12, 1940
TOP SECRET
The Fuehrer has decided that from now on until the spring, preparations for “Sea Lion” shall be continued solely for the purpose of maintaining political and military pressure on England.
Should the invasion be reconsidered in the spring or early summer of 1941, orders for a renewal of operational readiness will be issued later …
The Army was commanded to release its Sea Lion formations “for other duties or for employment on other fronts.” The Navy was instructed to “take all measures to release personnel and shipping space.” But both services were to camouflage their moves. “The British,” Hitler laid it down, “must continue to believe that we are preparing an attack on a broad front.”31
What had happened to make Adolf Hitler finally give in?
Two things: the fatal course of the Battle of Britain in the air, and the turning of his thoughts once more eastward, to Russia.
THE BATTLE OF BRITAIN
Goering’s great air offensive against Britain, Operation Eagle (Adlerangriffe), had been launched on August 15 with the objective of driving the British Air Force from the skies and thus achieving the one condition on which the launching of the invasion depended. The fat Reich Marshal, as he now was, had no doubts about victory. By mid-July he was confident that British fighter defenses in southern England could be smashed within four days by an all-out assault, thus opening the way for the invasion. To destroy the R.A.F. completely would take a little longer, Goering told the Army High Command: from two to four weeks.32 In fact, the bemedaled German Air Force chief thought that the Luftwaffe alone could bring Britain to her knees and that an invasion by land forces probably would not be necessary.
To obtain this mighty objective he had three great air fleets (Luftflotten): Number 2 under Field Marshal Kesselring, operating from the Low Countries and northern France, Number 3 under Field Marshal Sperrle, based on northern France, and Number 5 under General Stumpft, stationed in Norway and Denmark. The first two had a total of 929 fighters, 875 bombers and 316 dive bombers; Number 5 was much smaller, with 123 bombers and 34 twin-engined ME-110 fighters. Against this vast force the R.A.F. had for the air defense of the realm at the beginning of August between 700 and 800 fighters.
Throughout July the Luftwaffe gradually stepped up its attacks on British shipping in the Channel and on Britain’s southern ports. This was a probing operation. Though it was necessary to clear the narrow waters of British ships before an invasion could begin, the main object of these preliminary air assaults was to lure the British fighters to battle. This failed. The R.A.F. Command shrewdly declined to commit more than a fraction of its fighters, and as a result considerable damage was done to shipping and to some of the ports. Four destroyers and eighteen merchant ships were sunk, but this preliminary sparring cost the Luftwaffe 296 aircraft destroyed and 135 damaged. The R.A.F. lost 148 fighters.
On August 12, Goering gave orders to launch Eagle the next day. As a curtain raiser heavy attacks were made on the twelfth on enemy radar stations, five of which were actually hit and damaged and one knocked out, but the Germans at this stage did not realize how vital to Britain’s defenses radar was and did not pursue the attack. On the thirteenth and fourteenth the Germans put in the air some 1,500 aircraft, mostly against R.A.F. fighter fields, and though they claimed five of them had been “completely destroyed” the damage was actually negligible and the Luftwaffe lost forty-seven planes against thirteen for the R.A.F.*
August 15 brought the first great battle in the skies. The Germans threw in the bulk of their planes from all three air fleets, flying 801 bombing and 1,149 fighter sorties. Luftflotten 5, operating from Scandinavia, met disaster. By sending some 800 planes in a massive attack on the south coast the Germans had expected to find the northeast coast defenseless. But a force of a hundred bombers, escorted by thirty-four twin-engined ME-110 fighters, was surprised by seven squadrons of Hurricanes and Spitfires as it approached the Tyneside and severely mauled. Thirty German planes, mostly bombers, were shot down without loss to the defenders. That was the end of Air Fleet 5 in the Battle of Britain. It never returned to it.
In the south of England that day the Germans were more successful. They launched four massive attacks, one of which was able to penetrate almost to London. Four aircraft factories at Croydon were hit and five R.A.F. fighter fields damaged. In all, the Germans lost seventy-five planes, against thirty-four for the R.A.F.* At this rate, despite their numerical superiority, the Germans could scarcely hope to drive the R.A.F. from the skies.
Now Goering made the first of his two tactical errors. The skill of British Fighter Command in committing its planes to battle against vastly superior attacking forces was based on its shrewd use of radar. From the moment they took off from their bases in Western Europe the German aircraft were spotted on British radar screens, and their course so accurately plotted that Fighter Command knew exactly where and when they could best be attacked. This was something new in warfare and it puzzled the Germans, who were far behind the British in the development and use of this electronic device.
We realized [Adolf Galland, the famous German fighter ace, later testified] that the R.A.F. fighter squadrons must be controlled from the ground by some new procedure because we heard commands skillfully and accurately directing Spitfires and Hurricanes on to German formations … For us this radar and fighter control was a surprise and a very bitter one.33
Yet the attack on British radar stations which on August 12 had been so damaging had not been continued and on August 15, the day of his first major setback, Goering called them off entirely, declaring: “It is doubtful whether there is any point in continuing the attacks on radar stations, since not one of those attacked has so far been put out of action.”
A second key to the successful defense of the skies over southern England was the sector station. This was the underground nerve center from which the Hurricanes and Spitfires were guided by radiotelephone into battle on the basis of the latest intelligence from radar, from ground observation posts and from pilots in the air. The Germans, as Galland noted, could hear the constant chatter over the air waves between the sector stations and the pilots aloft and finally began to understand the importance of these ground control centers. On August 24 they switched their tactics to the destruction of the sector stations, seven of which on the airfields around London were crucial to the protection of the south of England and of the capital itself. T
his was a blow against the very vitals of Britain’s air defenses.
Until that day the battle had appeared to be going against the Luftwaffe. On August 17 it lost seventy-one aircraft against the R.A.F.’s twenty-seven. The slow Stuka dive bomber, which had helped to pave the way for the Army’s victories in Poland and in the West, was proving to be a sitting duck for British fighters and on that day, August 17, was withdrawn by Goering from the battle, reducing the German bombing force by a third. Between August 19 and 23 there was a five-day lull in the air due to bad weather. Goering, reviewing the situation at Karinhall, his country show place near Berlin, on the nineteenth, ordered that as soon as the weather improved, the Luftwaffe was to concentrate its attacks exclusively on the Royal Air Force.
