Also on 10th January 1941, Stukas badly damaged the Royal Navy carrier HMS Illustrious, and sank the cruiser HMS Southhampton on the 11th January. The Ju-87 also made a very good name of itself in the capture of the Balkans and Crete in the spring of 1941. Stukas devastated Royal Navy vessels during the Crete campaign, helping to send the cruiser HMS Glouchester to the bottom, also sinking the destroyers Greyhound, Kelley and Kashmir, and badly damaging several other RN ships.

And about the U-boats;

I wasn't suggesting that the U-boats were to operate in the channel, only that they were to close it - guarding the intrances, along with mines, waiting for the RN warships to appear. The remaining RN warships in the channel itself would be taken care of by the LW.

Cannot complain about your reply to the first question, How about the rest in particular the colliers.

Forgot to mention that the references to the Med don't count due to the extra training received and admitted some time ago.

How can the LW deal with the RN at night?

SO in May 1940 were Nazi fighters equipped to carry bombs? If so did they train to drop them and were they the armoured piercing type.

We seem to be allocating capabilities to the nazis here that they didnt have in 1940.

Didnt the Luftwaffe sink quite a few ships at Dunkirk just a few months prior to this "projected" invasion?

The Japanese used modified artillery shells as armour piercing bombs and blew the Arizona to pieces.

Dismissing the German pilots as being untrained in air-sea warfare is erroneous. Those pilots knew how to fly and how to drop bombs and had exerience in doing so. There expertise in air-sea tactics would grown in sorties not in days.

The danger of unprotected warships to airborne attack is grossly underestimated here. Also, completely ignored here is that the most knowledgeable person in air-sea warfare, Yamamoto, refused to expose his overpowering fleet to two carriers and one airfield and only 200 warplanes with no reserves available to the Americans. He knew there was grave danger without control of the air. With the Germans controlling the airspace over Eastern Britain, at the least Britain would be sorely pressed. You cannot win a war with airpower alone, but it is very difficult to win without it.

As I've said before, the Typhoons had an average miss distance of 110m (measured from post-raid photos). That's against targets they could see and were specifically aiming at. That means that 50% of the bombs dropped in an area of 40,000m2. A destroyer occupied about 1,000m2. Which gave a fighter-bomber a 1 in 80 chance of hitting a destroyer - when it's stationary.

Ju 87s were much better - a good crew had an average miss distance of just 30m. Say 50% of bombs hitting within 3,000m2. That gives them a 1 in 6 chance of hitting a stationary destroyer. Hitting a destroyer travelling at anything up to 35 knots is a different matter altogether - Ju 87s used to fly over the target then turn into a nice vertical dive - which is great if the target holds still, much less so otherwise. And a captain with any sense would wait until the Stuka was committed in its dive and then put the helm over....not an easy target to hit. And that's in broad daylight - the invasion fleet would have been too slow to make the crossing in a day.

The danger of unprotected warships to airborne attack is grossly underestimated here.

Not. At. Night.

Don't get me wrong, I agree that the RN would certainly have taken losses, but they would have been a long way from being "sitting ducks". And their losses would have been nothing like as much as those helpless low-freeboard barges stuffed with soldiers and gear. The crossing would have been extremely expensive for the invaders, and the worst would have been still to come, because the Germans would have had to send a continuous stream of vessels (aka targets) to keep those troops which made it ashore supplied. All the studies and war games I've read conclude that this couldn't have been done - it would have ended in the complete defeat of the invasion.

If the Germans had no real chance of victory over the Brits in the summer of 40 why is there all the hoopla over the Battle of Britain

Only because of 20 miles of water, the RN, and the RAF.

[the lancaster kicks ass]

PB it's just as much about what the battle is symbolic of than what it did, it was the first time in the war that the Germans had suffered a major setback (trying not to use the term defeat), it was a symbol of Britain standing alone againt the entire might of the German war machine, our boys were defending and fighting for their home land to the death with their backs to the wall, making a last stand, and for the first time the war was no longer phoney but real for the British people and they got behind it! the invasion probably wouldn't have worked but it'd be a damn sight easier for Jerry with German local air superiority......

[Tony Williams]

Agreed. And it is one thing to take a calm objective view now, which shows that the invasion almost certainly could never have succeeded, and quite another to be faced with the prospect of such an invasion at the time, especially since they did not know then what we know now. All they knew was that the Wehrmacht had smashed their way through Poland and France in an unbelievably quick time - the rest of the world was in shock.

In any case, before the war it was generally believed that "the bombers would always get through", and assumed that London would be destroyed in any air war - that's why children were evacuated at thhe start of the war. Just fending off the Luftwaffe and forcing them to stop their daylight attacks was a huge real and psychological victory by itself, quite apart from the fact that it made an invasion impractical.

The Japanese planned and trained for the Pearl Harbour attacks for months beforehand.

I'm sure it is not at all feasible to suddenly decide to stick a bomb on an Bf-109 and send the pilot off to sink a Destroyer with no training.

Maybe the Nazis could have gone the whole hog and simply crashed their aircraft into the Cruisers and Destroyers? This would have at least ensured a hit and would have been more effective than the Japanese were in 1945 as the ships AA was far less powerfull then.

I'm not erroneously dismissing the quality of the German aircrew, but it is a fact that they couldnt just simply switch tasks on the spot. I dont think that a Bf-109 could even carry a bomb in 1940. Does anyone know if they did this before 1941?

It was the 'Indomitable British Spirit' that made the Germans sit up and take note.... the RAF, the RN and the Army are just the organised military arm of this spirit...the physical representative if it if you like.

An invasion of Britiain isn't a one round fight, it's multiple rounds going against different oponents with differing fighting capabilities..

On top of the 'fighting spirit' one has to look at the very geology of the UK, it's very shape and disposition...

Blitzkrieg work in the UK... not a cat in hells chance...

The German might well of after massive fighting have captured London, but where to from there ?

Devon and Cornwall.... not even us Brits would have control over this area if the people there didn't allow it.
Scotland.... no
Wales.... no
The Midlands... have you seen Derbyshire ?

So the only area I see as being feasible to hold onto would be the area south of the Thames.....

But the losses to achieve this would have been crippling

Was Sealion possible?

Would the RN surface fleet have taken damage if they sallied against a German invasion fleet? Yes.

Would the RN likely have crippled the capacity of the Kriegsmare to carry out an invasion? Yes.

Would air superiority make their job more difficult? Yes.

Would air superority help in darkness? No.


The Germans proposed this for Sealion:

Carrying out an 11 division (9 seaborne 2 airborne) invasion via a heavily contested sea lane over the course of 10 days. Carry an additional 7-10 divisions over another 40-50 days.

Compose your invasion fleet of 30% military and civilian transports and 70% river barges and other pressed into service craft.

Protect them while they transport 110,000 men and their equipment and supplies for a 10 day to 2 month period with a fleet that is outnumbered by 5:1 in captial ships, 4:1 in crusiers and 5:2 in destroyers, against an enemy operating in home waters from protected bases.

Land your outnumbered invasion force with no element of suprise and no prepatory bombardment against prepared costal defences and three rings of inland defences, bringing little organic heavy equipment with them (including no heavy artillery) until the second week of the campaign.



Logistically, they would of had to run a shuttle system of barges for 14-16 hours a day to keep the army supplied, assuming low levels of expenditure and the capture and return of Folkstone and Dover to full working conditions within 2 weeks. Any interferance from the RN send this into haywire mode, stranding those German troops that did land without fuel, ammunition, food and other supplies.

What people obviously forget is that Germany at this time was preparing for an even larger objective - the invasion of Russia. Had Hitler concentrated on Britain alone, waiting with the overly large objective of an invasion of Russia, an invasion of Britain, if you ask me, was entirely plausible.

I'll be back later to address the rest.
