  1.  @MoneyIsSilver  'The Royal Navy was already getting picked apart by the Luftwaffe, though, even before Dunkirke.' Really? In the whole of WW2, the Luftwaffe sank 31 RN destroyers, and no RN warship larger than a light cruiser. Indeed, the Luftwaffe only managed to put a torpedo bomber into to service in mid 1942. By September 1940, the RN had been 'picked apart' in your words, to the extent that, entering the war with 193 destroyers, there were 'only' some 182 destroyers listed as operational or refitting in the RN Pink List for 16 September. The Luftwaffe, untrained in anti-shipping techniques, had failed spectacularly at Dunkirk, managing to sink only four of the 41 destroyers which were the backbone of the evacuation fleet, whilst the RN, ordered to evacuate 40,000 specialist troops, brought out 323,000 men. Actually, whilst the Luftwaffe did have air superiority over the Channel, largely because Fighter Command pilots were ordered to stay over the mainland to maximise their chances of survival, Germany never had the remotest hope of transporting an invasion force across it, given their almost total lack of escort vessels and assault ships. By the way, whilst U-Boats did achieve a degree of success in the wider Atlantic, this was because RN escorts had been temporarily withdrawn to form the Admiralty's massive anti-invasion forces, and had precisely nothing to do with the Luftwaffe. U-Boats did not operate either in, or through, the Channel, because it was something of a death trap. Three boats were sent to operate there in late 1939. They, and their crews, are still there. 'Churchill - thought the Brits were fucked.' You think so? How was it then that, in August 1940, he was confident enough to send a large troop convoy to North Africa? Look up Operation Apology for further information. In short, stop believing in myths and buy a proper book on the subject.

  8. Operation Mercury? That was the one where the Royal Navy prevented any axis reinforcements reaching Crete by sea until the ships were diverted to evacuation duties, wasn't it? The one where one convoy was annihilated, and the second returned to Crete. Dunkirk? 'Ran them off?' Do you mean when the Royal Navy was ordered to evacuate 40,000 technical specialists, and actually lifted 338,000 troops? When, of 40 RN destroyers involved, four only were lost to air attack? Where, in fact, 235 vessels were lost, of which 142 were small boats simply abandoned at the end of the operation, and 27 were vessels smaller than tugs? Where, of 373 allied warships ranging from MTBs to a cruiser, 39 were lost, 7 of which were to collision or grounding? Simply quoting inaccurate figures out of context merely discredits any argument you may think you have. As usual for a Sealion fan, you then indulge in all the 'would haves' about the mighty Luftwaffe. In 1940, the Luftwaffe had not been trained in anti-shipping operations, hence the failure (contrary to your view, of course) at Dunkirk. Moreover, the Luftwaffe lacked an operational torpedo bomber until mid 1942. Indeed, in the whole of the war, the Luftwaffe sank 31 RN destroyers, and no RN warship larger than a light cruiser. Even their own commanders, Wolfram von Richthoven & Oskar Dinort, believed that protecting an invasion force was beyond their capabilities. To put your absurd nonsense about sinking 'half the Home Fleet' into perspective, the RN in September, 1940, had around 70 destroyers and light cruisers in bases within five hours' steaming of Dover, backed up by around five hundred smaller warships. There were a further 40 or so destroyers also in Home Waters. I haven't, of course, mentioned the Home Fleet, as most of it was at Rosyth, guarding against a potential sortie by (actually, non-existent) German heavy ships. The Admiralty, of course, had concluded that faster, smaller, vessels with quick firing weapons were better equipped to deal with the Rhine barges towed by tugs which passed for the German invasion fleet, and which the Kriegsmarine estimated would require eleven days, and nights, to land the first nine divisions. Nights, by the way, are when the RN could operate, and when your mighty Luftwaffe couldn't. So, your 'after the Luftwaffe sank half of the home fleet the rest WOULD HAVE withdrawn' is wide of the mark as well. Ju52? You mean the 220 or so which was all the Luftwaffe had operational in late August, 1940, after they had not replaced their heavy losses in the Low Countries? You must account for further losses during the paratroop dropping stage of the invasion, although possibly not that many as the Germans only had just under 4000 paratroopers available at the time. Supplying the 800 tons per division that was the minimum a German infantry division required when in action would be a further challenge, of course, but not much of one as it presupposes that any of these formations managed to land in the first place, although I assume you will say that they 'would have.' Resupply by ships during the day? Which ships? The Germans had a small number of coasters which were to be used to tow barges, but few proper supply ships, and where would these supplies be landed from these non-existent ships in any case? 'The Luftwaffe even this early in the war was very effective against ships , especially this close to their bases.' Actually, close to their bases or not, quite the opposite is the case. How else do you explain their failure during 'Dynamo?' Instead of indulging your wish fulfilment fantasies about what the Luftwaffe 'would have' done, perhaps you might read up about what the Luftwaffe actually did, or more precisely, didn't/couldn't do, in 1940? Then, instead of talking about 'sinking half the Home Fleet' you might read up on precisely how large the Royal Navy in Home Waters was at the time.

  14.  @sebclot9478  Actually, I probably am as good, or at least as knowledgeable, as I think I am. Happily, my publishers and readers do rather seem to agree. 1) My reference to Compass and Beda Fomm was simply to educate you concerning what actually happened to the (largely infantry, and badly equipped) Italian army in Libya. 2). The US never assumed convoy escort duties from the British, least of all from 1942. In January, 1942, the US Navy proposed a Mid Ocean Escort Force of 14 Groups. These were to consist of 15 US destroyers, 27 RN/RCN destroyers, and 101 RN/RCN Flower Class corvettes. Initially, there were 5 US Groups, made up of US destroyers and RN/RCN corvettes, 5 British, and 4 Canadian groups.By winter 1942-3, the US had withdrawn from the Allied Mid-Ocean Escort Groups almost entirely. Two US Groups, A1 & A2, were disbanded when their destroyers were re-assigned, and A4 & A5 had their US destroyers replaced by RN ones, at which point they became British Groups B6 & B7. The one remaining US Group, A3, actually consisted of two US coastguard cutters, with RN/RCN Flowers. When the cutters were reassigned, A3 became the Canadian Group C5. Thus, by early 1943, there were 12 Mid Ocean Escort Groups, B1-B7 and C1-C5. US vessels operating in the Atlantic by then were working between the US and the Mediterranean, not in the North Atlantic. 3). I did ask you to provide details of convoys which sailed to Britain from the Far East via the Suez Canal and the Mediterranean. Where are those details? 4). Have you actually read Mein Kampf? The Soviet Union was, first and last, Hitler's main target. You might perhaps read the reasons for this in 'The Last Days of Adolf Hitler' by Trevor-Roper. 5). Perhaps you might explain how, having marched through Spain, captured Gibraltar, and then withdrawn, what presumably would an isolated German garrison do to maintain itself? Eat the Barbary Apes, perhaps? 6). That is your opinion of Bismarck. The flaws I have described earlier still existed. Bismarck's only advantage over the RN's Nelsons and KGVs was her speed. In a situation where she was obliged to engage, she was outclassed. 7). Do you not remember posting 'The fact that I mentioned ONLY the Bismark by name doesn't mean that it would have been the only German ship to participate in such an operation. I can't believe I actually have to explain that to you.' I merely responded by telling you exactly what naval resources were available to the Germans at the time, as clearly you didn't know for yourself. I chose September, 1940 as even you could look it up without much problem, as the resources available to both sides are well documented. You can choose any month in WW2 to suit yourself, as things hardly got better for the Kriegsmarine, after the punishment it received during the Norwegian campaign. Are you even aware how totally outmatched the German surface fleet was, throughout the war? 8). & 9).Of course the British weren't responding to German provocation, as there was no such major U-Boat construction programme. My contention is that, had there been such a programme, the British would have responded, just as they had to the Kaiser's actual fleet expansion before WW1. By the way, if you think there was a 'scaling back' explain these figures :- U-Boat Construction by Month :- 1939, Sept. 1, Oct. 0, Nov. 2, Dec 3. 1940, Jan. 1, Feb, 1, March, 2, April, 3, May, 3, June, 3, July, 3, Aug, 5, Sept, 7, Oct, 8, Nov, 9, Dec. 9. 1941, Jan. 11, Feb. 9, March, 11, April, 14, May, 19, June, 15, July, 19, Aug, 19, Sept. 15, Oct. 24, Nov. 24, Dec. 22. 1942, Jan. 15, Feb. 16, Mar, 18, April, 17, May, 20, June, 21, July, 21, Aug. 21, Sept. 19, Oct, 23, Nov. 24, Dec. 23. 1943, Jan, 22, Feb, 21, Mar, 27, April, 18, May, 26, June 25, July, 26, Aug. 21, Sept, 21, Oct. 27. Nov. 25, Dec. 31. 1944, Jan. 20, Feb. 19, Mar. 23, April, 23, May 19, June, 11, July 15, Aug. 15, Sept. 20, Oct. 16, Nov. 22, Dec, 27. 1945, Jan, 37, Feb, 21. Mar. 26. Where exactly is your imaginary 'scaling back?' 10). Oh, so now Gibraltar is not to be attacked until AFTER North Africa, Suez, and Malta have been conquered? By the way, Suez is in North Africa. There are many excellent academic studies on the subject of WW2, and in particular of the period leading up to Barbarossa. Have you ever thought of reading one or two, before you wander off into further silliness?

  15.  @sebclot9478  Whether I am arrogant or not is irrelevant. The specialists (usually retired military men, in the most recent case a Rear-Admiral & a Major General) examine my submissions, ask questions if they have them, and only after that are the proofs passed on to the publisher. All I would say is that reviews by academics and military historians have been overwhelmingly position. Clearly, such people lack your enormous breadth of wisdom and understanding. Either that, or my views are credible, and yours are somewhat lacking. You were the one who brought Suez convoys up, but now you choose to disregard them. Very wise, as there is nothing there to support you. Of course Hitler's primary enemy was the Soviet Union. Clearly you haven't read Trevor-Roper's analysis of the reasons for the initial preventative attack on France. You should, as it explains how, despite Hitler's contempt for Kaiser Bill's two front war, he subsequently placed Germany into a worse situation from 1941 onwards. Explain to me why, when Germany was seeking to defeat the largest maritime power on earth, :- 'It doesn’t matter if the German surface fleet was outclassed. Again, raw data with no understanding of what any of it means to the overall picture.' By 'raw data,' I assume you mean 'facts and figures?' I can well understand from the nature of your argument, such as it is, your urgent need to disregard facts and figures. Explain to me what the raw data does actually mean, if you would be so kind. 'Maybe the British would have responded to U-boat building program. Maybe not. I guess we will never know for sure. And what exactly do you think a scaling back would look like?' No. You explain to me why, when the British had responded strenuously to the Kaiser's naval expansion before WW1, they would simply have ignored a similar U-boat expansion programme in the 1930s? In short, nothing that you write has any grounding in the real military, and particularly the naval, situation of 1939-1940. As I said, you are wise to ignore facts, as they dismantle your musings even more effectively than I have.

  37.  @sebclot9478  The Italians had possessions in Libya, Ethiopia, Eritrea, and Somalia. Other than Libya, these were cut off entirely from re-supply, and eliminated completely by November, 1941, after the Battle of Gondar, with 230,000 Italian and colonial troops surrendering. 1). The main Italian forces in Libya were annihilated by Operation Compass, ending with the Battle of Beda Fomm on 6-7 February, 1941. That was, of course, why Hitler was obliged to send a small German force to shore up what was left of Italian Libya. 2). The US only even appeared in North Africa in November, 1942. Italian losses during the period to the end of the campaign were 2.1 million tons of merchant shipping, 83 warships, totalling 195,100 tons, and 83 submarines. Of the surface ship losses, 161,000 were sunk by British & Commonwealth forces, and 33,900 by US forces. Would you care to re-assess your opinion of the extent of the American role? 3). The Suez Canal was simply not used by the British to a significant extent in the early part of WW2. Merchant shipping went by the Cape route, which was longer but safer. The axis had significant aerial forces in the Mediterranean area, which made the passage of merchantmen dangerous. Simply read any academic study of the campaign. Better still, tell me the identity of a single British convoy which sailed to Britain through the Suez Canal during that period. Good luck with that! 4). Perhaps, but the fact is that they didn't, and certainly weren't willing to after June, 1941. 5). I have already explained the situation of Spain in 1939-1940. I suggest you read up on the immediate aftermath of the Civil War to educate yourself. Do you seriously think that Germany could invade Spain in order to capture Gibraltar, then simply pack up and go home? Seriously? I always find the entertaining opinions of those who think German resources were inexhaustible quite fascinating. 6). Good luck with using Bismarck in late 1940 or early 1941, as she wasn't even declared operational until May, 1941. In point of fact, Bismarck was very conservative in design. Three major obsolete features being her four main turrets, resulting in excessive length and therefore displacement, her more or less useless 5.9 inch low angle secondary armament, and most important of all her long outdated incremental armour, when other navies had moved to the superior US conceived all or nothing pattern. Still, you can't expect much more of what was essentially an improved Baden, I suppose. 7). You need to explain it to me. In September, 1940, the Germans had only one operational heavy cruiser, three light cruisers, and ten or so operational destroyers or large torpedo boats. Scharnhorst and Gneisenau had been damaged during the Norwegian campaign, and weren't even operational again until November, 1940. Please tell me which other ships, again? 8).& 9). I actually wrote, 'Build more U-Boats? I assume that, as these are being built, presumably in the pre-war period, you expect the British to sit back, say 'I wonder why the Germans are building U-Boats?' and not expand their own escort production programme?' I know exactly the nature of the German U-Boat programme between 1939 & 1945. As you would have grasped had you actually read the above, I was referring to earlier reference to a 'scaling back' of the U-Boat war, which didn't actually happen by the way. The point you seem unable to grasp here is that U-Boat construction could only be aimed at one target, and the British, dependent on imports for survival, would act accordingly. 10). Sorry, I had rather lost interest by that stage, so fantastical was your post. Please look up the full extent of the shore batteries which existed on Gibraltar at that time, and then read up on Force H and DF13, both based on Gibraltar. In September, 1940, these consisted of one battleship, one battlecruiser, one carrier, and fifteen destroyers. When you have done that, tell me which forces were available across the Straits which could successfully have overcome these defences.

  61.  @sebclot9478  The British weren't in South Africa. In 1941, they had substantial forces in NORTH Africa. Moreover, historically, the Italian Navy struggled to maintain supply levels to the smallish axis forces in North Africa, because of the inconvenient presence of the RN & RAF in the Mediterranean, combined with the serious lack of port facilities in the region. The Suez Canal was of little importance in the first half of WW2, largely because British convoys went round the Cape. Supplies for 8th Army were landed at the southern end of the canal and moved by rail. The Canal itself was used almost entirely by warships sailing to join or to leave the Mediterranean Fleet, although often these used the Mediterranean via Gibraltar, as did Malta supply convoys. As the Italian navy was, historically, seriously hamstrung by lack of fuel, and rarely, in the case of the heavy ships, risked action, your Gibraltar option is not credible. Moreover, Franco was never in a position to join the Axis, as Spain relied on US food aid to stave off mass starvation, and FDR had already made el Caudillo well aware that the day Spain did join the Axis was the day this aid stopped. Furthermore, have you actually considered the logistics problems facing a German force passing through Spain even to get to Gibraltar? Bismarck was sunk, by the way, in May, 1941, so is irrelevant to the issue, even if one warship built to a semi-obsolete design could make any meaningful contribution to anything. Build more U-Boats? I assume that, as these are being built, presumably in the pre-war period, you expect the British to sit back, say 'I wonder why the Germans are building U-Boats?' and not expand their own escort production programme? Sorry, what you propose is far from 'easy.' It is fantasy based on a lack of knowledge.

  97.  @cybereus836  Actually, I said 'I merely stated a whole series of facts' which I did. The facts were taken from the Royal Navy Pink List, from 16 September, 1940. Look it up for yourself. It will prove that I am correct. 'The thing you discount which Forcyzk mentioned is: having boats in the general body of water encompassing England does not discount that those Boats now have to FIND that invasion flotilla.' Oh, please! The Royal Navy patrolled the Channel every night, with destroyer patrols from Plymouth & from The Nore. Occasionally, the destroyers would shell the invasion ports as they passed. Moreover, the Kriegsmarine estimated that the time required to extract the barges from their ports, form them up into their box formations (with the barges being towed, in pairs, by tugs, trawlers, or small coasters, at just above walking pace), then proceed down the Channel, to the landing beaches between Folkestone and Brighton, would, in the case of the largest formation (380 barges from Boulogne & Le Havre) require THREE DAYS. Moreover, the formations from Ostend , Dunkirk, & Calais would pass through the Straits, which are 25 miles wide. Find them? Please don't be silly. The barge trains would have been clearly visible from Admiral Ramsay's HQ at Dover Castle. If Mr. Forcyzk didn't know that, then his research was sadly lacking. You might like to read 'Invasion of England, 1940' by Peter Schenck, for the German view, which actually agrees with mine, by the way, and provides details of the complete plan. In point of fact, as a naval historian, I have not much concerned myself about the Battle of Britain, because the main defence against invasion was always the Royal Navy. As Admiral John Jervis, Earl St. Vincent, told Parliament during the Napoleonic invasion threat " "I do not say they cannot come, I only say they cannot come by sea". Most modern historians, by the way, agree that Sealion was never a realistic operation. Didn't you know that?

  109.  @dragilxcom4176  Another Sealion 'would have.' The Channel is a death trap for submarines, being shallow, subject to strong currents, and heavily mined. The Germans sent three boats into it in late 1939, and all were promptly sunk. Furthermore, the U-Boat fleet at the time was small, with only 27 operational front-line boats, of which 13 on average were at sea on any one day in September, 1940. Usually, boats tried to avoid going near fleet destroyers, as it tended to end badly for them. You suggest that, in order to satisfy your fantasy, they should actively seek them out? Oh well, ignorance is bliss, I suppose. 'If Germany had the air superiority, RN would have no chance.' You mean like at Dunkirk, when the Luftwaffe, with air superiority, failed to prevent Dynamo, when the rescue ships were sitting targets? This same Luftwaffe, untrained in anti-shipping operations and without even a torpedo bomber, 'would have' been able to sink or disable, in large numbers, RN warships moving at speed, when they previously hadn't been able to hit them when they were stopped close inshore? This Luftwaffe you laud, which historically in WW2 sank 31 RN destroyers, and no RN warship larger than a light cruiser, 'would have' dealt with the 64 RN destroyers on anti-invasion duties within 5 hours steaming of Dover, supported by several light cruisers and over five hundred smaller warships, and after that 'would have' dealt with the further fifty or so RN destroyers further away, but still in Home Waters? Instead of posting from ignorance about what the Luftwaffe 'would have' done, why not buy a book, read about what, historically, the Luftwaffe actually did (or rather didn't,) do, and then try to explain it?

  125.  @gabrielm.942  Sorry, but it is true. Assuming that an invasion attempt was to be made in the latter half of September, 1940, then :- Gneisenau : Torpedoed by HMS Clyde off Trondheim in June 1940. Repairing in Kiel. Repairs completed in December, 1940. Scharnhorst : Torpedoed by HMS Acasta in June, 1940. Undergoing repairs in Kiel. Repairs completed in December. Deutchland : Torpedoed by HMS Spearfish in April, 1940. Severely damaged, and undergoing repairs in Kiel. Repairs completed by April, 1941. Admiral Scheer : Refitting in Danzig for a raiding sortie. Refit completed mid October, 1940. Blucher : Sunk in April, 1940. Bismarck : Commissioned in late August, 1940, then sent to the Baltic for sea trials and working up. Modifications completed in January, 1941, and working up completed in April, 1941. Prinz Eugen :- Commissioned August, 1940. Baltic trials until December, after which modifications made in Kiel. Resumed working up in the Baltic, operating with Bismarck. Work up complete in April, 1941. Schlesien. : Secondary armament removed to equip merchant raiders late in 1939. Used as an icebreaker in the Baltic thereafter, until laid up as an accommodation ship with a skeleton crew July - December, 1940. Schleswig-Holstein : Supported the invasion of Denmark in April, 1940. Used as a training ship thereafter, with secondary armament removed for use on merchant raiders. I submit that using these two hulks as troop transports would have been the height of folly. The British had 18 destroyers and 2 cruisers based at Sheerness, 6 destroyers at Harwich, 3 cruisers and 5 destroyers in the Humber. Not to mention 2 battleships, 1 battlecruiser, 3 cruisers and 17 destroyers at Rosyth. That leaves Hipper, operational but with defective engines, the light cruisers Koln, Nurnberg & Emden, 7 operational destroyers (plus a further 3 refitting/repairing) and nine Wolf/Mowe torpedo boats.

  130.  @stephenarbon2227  The British were outproducing the Germans in aircraft, and particularly fighter aircraft, by mid 1940. By Spring, 1941, the RAF had 56 squadrons of Fighters & Fighter-Bombers carrying out regular fighter sweeps over northern France. Furthermore, also by Spring 1941, the new warship construction which the British had begun in 1939 was coming into service, in particular large numbers of L, M, & N class destroyers, supported by Hunt class escort destroyers, sloops and corvettes for convoy escort, and the ex American four stackers also for convoy duties. In cruisers, the remainder of the first group of Didos, and many of the Colony class, were now with the fleet. If the RN was out of sight in September, 1940, superiority was on a different planet by Spring 1941. As to U-Boats, firstly the Channel is a most unsuitable place for them. In 1939, the Kriegsmarine attempted to send three boats on operations in the Channel. They are still there. Furthermore, in May 1941, the Kriegsmarine had 33 operational front line boats, of which an average of 24 were at sea on any one day. Moreover, the usual role of a WW2 boat was to attack merchant shipping. The probability of success against large numbers of fleet destroyers and experienced convoy escort vessels was minimal. Finally, if you think that the Royal Navy of mid 1941 could not have survived, then you simply have no grasp of precisely how huge the Royal Navy of that time really was. Moreover, why should the British send capital ships into the Channel in any case? What purpose would they serve there? The RN anti-invasion preparations of 1940 had been built around large numbers of light cruisers, destroyers, and supporting smaller warships, actually, over 500 of them. What do you think might have changed by May, 1941?

  147.  @LittleMacscorner  I'm not getting upset, but I do know quite a lot about Dynamo & Sealion, as they formed the bulk of my modern history thesis. Many of the German generals did actually believe that Sealion was nothing more than 'an extended river crossing' and Admiral Raeder spent much of the summer of 1940 desperately trying to get them to grasp that it was nothing of the sort. Hitler's certainly didn't want to attempt an invasion; he assumed that Britain would accept a negotiated peace, and was near to being proved correct. A government led by Lord Halifax wouldn't have had a problem with the idea, and Hitler believed that a neutral Britain left him with a free hand to deal with his true enemy, the Soviet Union. The result of all this was, in Napoleon's words 'how can an elephant fight a whale?' Certainly, a substantial German force on British soil was unlikely to have been defeated, but, even if a successful invasion was essential, without a navy or even suitable troop transports the possibility of carrying out a successful crossing against the kind of resources available to the Royal Navy was never even a remote possibility. Unlike a land battle, where a smaller force might overcome a larger one by a cunning strategy or as a result of incompetence on the part of the larger force, the Kreiegsmarine, following the mauling it suffered during the Norwegian campaign, knew exactly what the towed barges could expect once they entered the Channel. It is a bit like the old joke about a motorist asking directions and being told by a local 'If I were you I wouldn't start from here.' In the summer of 1940, the Germans found themselves in exactly the same quandary.

  157.  @johnburns4017  Rather more than that. The barge trains first had to form up in long columns outside their ports. For example, the train carrying the leading elements of 26 & 34 Infantry Divisions, heading for Bexhill - Eastbourne, consisted of 165 tugs and 330 barges from Boulogne, and 25 tugs with 50 barges from Le Havre. Each tug towed two barges, one powered and one unpowered. It would take more than a day to extricate this lot from port, and form them up into any sort of coherent formation. The formation heading for Folkestone-New Romney ( 75 tugs and 150 barges from Dunkirk & 25 tugs with 50 barges from Ostend) had greater problems, given the state these ports were still in. The Kriegsmarine estimated that it would take three days to assemble the formations, move them westward down the Channel, turn them towards the English South Coast, and push the barges to shore, using the tugs and a number of smaller, pusher, boats. That was for the first part of the first wave, consisting of about a third of each division, without most of their wheeled transport or divisional artillery. The time needed to get the whole of the nine divisions ashore, still without wheeled transport or artillery, was estimated at eleven days. This assumes, of course, that weather conditions in the Channel would remain benign (which was, I suppose, possible) and that 'external factors' would not come into play. I believe that the 'external factors' Raeder had in mind were hundreds of dark grey ships, each flying a white ensign. The whole lunacy is described in considerable detail in a book written some years ago by a German author, Peter Schenck.

  162.  @shb7772000if  October 10, 1940. HMS Revenge with destroyer escorts shelled the barge concentrations at Cherbourg. Revenge fired 120 high explosive 15 inch shells, supported by 801 4.7 inch shells from her escorts. Whilst returning to port, the heavy German gun batteries fired at her, but missed. In point of fact, by the end of August there were over 150 medium, heavy, and super heavy German batteries on the French coast, which began firing at British coastal convoys from 12 August. Between August & December, 1940, some 1880 rounds were fired at these convoys, often involving as many as 200 rounds. Number of hits? NONE. In fact, the batteries, during the whole of the war, achieved precisely no hits on any convoy. So, maybe German land artillery COULDN'T hit ships in the Channel. Other than that, why exactly should British ships not go into the Channel? There was no actual prohibition, rather their presence there would have served no purpose, unless heavy German ships did the same. The right place for British capital ships in Home Waters was Rosyth, and later Scapa Flow, from where they could intercept a potential German sortie into the Atlantic. Incidentally, the Battleship Queen Elizabeth was in Portsmouth until December, 1940, undergoing modernisation. A sitting duck, perhaps? Not really. During the course of numerous Luftwaffe raids, she received no hits. The fact that the Channel is not as wide as the Mediterranean is irrelevant, as Luftwaffe & Italian aircraft in the Med. had ample range to reach British ships. Moreover, in the Med. the British, unless they had a fleet carrier available, had no air support at all. Indeed, the Japanese sank two British capital ships. WITH TORPEDO BOMBERS, a weapon not available to the Luftwaffe until 1942. By the way, what relevance has any of this to Sealion. I have already told you that capital ships played little or no part in the Admiralty's anti-invasion dispositions, for blindingly obvious reasons.

  203.  @dragilxcom4176  'Could have' is actually defined as 'something was possible in the past, but it did not happen.' In other words, it embraces a possibility. Your 'Germany could have shrink Royal Navy with the U-Boats and Luftwaffe bombing' claim does not meet that definition, in that your blithe assumption, presumably based on a clear lack of actual knowledge, was not within the bounds of possibility. Of course air superiority became dominant later in the war, but if the subject is Sealion then the time is 1940, or more precisely September, 1940, and the air force concerned is the Luftwaffe, then it was still far from attaining that pre-eminence. The strength of the Luftwaffe in 1939-1940 was as a ground attack force, operating in support of the army. It did not receive any training in anti-shipping operations until Fliegerkorps X began receiving some later in 1940, after Sealion had been abandoned. You haven't challenged the facts I have stated about the Luftwaffe's lack of training, their failure at Dunkirk, or their 'successes' against RN destroyers, I notice. Oddly, you Sealion 'would haves' never do. Probably wise on your part. Incidentally, although not particularly relevant to my argument, the British were outbuilding the Germans in aircraft, and in particular in fighter aircraft, by June 1940 at the latest. Whether the Luftwaffe had or hadn't torpedo aircraft technology is irrelevant. The first use of such aircraft, apart from a handful of successes by seaplanes against unarmed merchantmen in the north, was against PQ15, en route to Russia, in May, 1942. Indeed, Goering, on 28 November, 1940, banned the use of the handful of available seaplanes on such operations, and cancelled the production of the LTF-5b, the Luftwaffe's aerial torpedo of which a tiny number existed in 1940. Incidentally, Hitler did not allow the British to escape, as the decision was made by von Rundstedt, commander of Army Group A. He wished to rest his armour prior to commencement of the second phase of the invasion of France, and feared the possibility of a second 'Miracle of the Marne.' Finally, I am sorry that you criticise the facts I have stated as 'historical innuendo,' and seek to hide behind your singular self-proclaimed definition of 'could have' rather than continue any discussion, although I appreciate that Sealion enthusiasts and historical facts do not work well together.
