One of the major tactical advantages possessed by Fighter command was radar, and - as you no doubt know - they used it to anticipate Luftwaffe movements and where possible, attack with superior numbers and with the sun behind them. With an invasion fleet on the water and troops on English soil, the Luftwaffe is forced to maintain fighter cover over those assets 24 hrs per day, as well as providing extra fighter escorts for any bombing raids - whether tactical or strategic.
As you undoubtly know
- Luftwaffe also had radars
And they would have strong AAA support advantage other british bombers.
Not only was air superiority never achieved, but risking the whole fleet was never required. The Channel is small-ship territory - far too shallow for good sub operation - and the RN had a large advantage in numbers of Destroyers, Corvettes. Mines cut both ways. The British also had minefields to protect their vulnerable ports. Reread my point about requiring the Luftwaffe to cover extensive assets with limited resources.
Any large vessel coming close will be easely sunk by aviation, coastal artillery and subs. It is much easer to clear small way from one coast to other off mines for transport vessels than whole area between France and UK for large military vessels. Transport vessels required to cross 40km water are very cheap - true military vessels are not. Germany could even allow itself to lauch these vessels as 1-way only - it is still very economically viable. Try to launch new destroyer or corvete every day...
The ability of the Germans to land troops on English soil was also severely limited. Once the Germans had committed their invasion fleet, the English did not have to plan to defend the whole of their coastline, but could concentrate sufficient troops to equal or exceed the numbers that the Wermacht could land and suport with available resources. It didn't matter how many divisions Hitler had in France. What mattered was how many he could get to England, and how much equipment he could send with them. It is highly unlikely that the Germans could have achieved the superiority in numbers or equipment that is usually required to mount a succesful attack.
There were such plans. They required huge resources and suggested large losses. In retrospect, these "huge" resources and "large" losses were much smaller than even losses for half-succesfull part of blitzkrieg - i.e. up to Moskow offencive part.
Actually, No.
German High Command also considered an assault on England with then-available resouces to be unlikely to succeed. However the planning has to be done in order to demonstrate this, and the sigh of relief when Hitler said "Not this time" was pretty heartfelt.
With just available - yes. But if ALL resources and prepatations were commited to such task - it looks doable.
The problem was that , having started the war, Hitler was not at liberty to stop it on his own terms. It is debatable whether his timing was off, but he considered the USSR to be highly untrustworthy and a natural enemy which would have to be dealt with at some stage in order to secure his eastern frontier.
He considered USSR as enemy, yes. As untrustworthy - yes ( is there anyone he trusted anyway? lol). As immediate or even close term threat - no. GB, on the other hand, was immediate threat. Already in war. It was very, very stupid to start a new war while not ending previous one.
Having concluded that an invasion of England was currently impossible, his options are pretty much as follows.
Lets assume it.
~ Peace with England would have required abandoning his conquered territory in Western Europe and possibly, Poland (remember why England declared war in the first place). Without an invasion threat, England (particularly under Churchil) was unlikely to accept peace under Hitler's terms.
No go. Giving up everything Germany gained - for what? For a untrustworthy peace? Practically, you suggest surrending to Germany to UK.
~ Conquering England required diverting his armaments industry to the building of a Navy that would be at least comparable to the RN, and that requires playing catch-up, beacuse the English were not exactly letting their shipyards lie idle, either.
Nope, true navy was much less important than luftwaffe and erzatz-navy (basically cheap floating artillery batteries instead of true blue water ships)
This diversion of men and resources can only come at the expense of other war supplies - tanks, guns, planes - which degraded Germany's ability to deal with the perceived Russian threat. .
As i already told, there were NO
perceived Russian threat! No germany (or USSR) internal documents suggested such threat! Hitler attacked USSR exactly BECOUSE he thinked USSR army was very weak and incapable!
~ In theory, a successful blockade might have starved England to the bargaining table, but this was never achieved. Even at its height, the U-Boat campaign was not sinking shipping tonnage as fast as the Americans were building it.
Yes, if only not the war on the Eastern front which diverted most resources...
Transporting those assets across the channel was THE problem.
No air superiority.
could be achieved IF not the eastern front...
Could be negated by deny RN the access to vital area near the La-Manche
By the summer of 1942 (any invasion required reasonable weather) The English had had two additional years in which to prepare a defence in depth and conscript and train more personnel. The American Air Corp was in England and conducting raids into Europe. US Army troops were in place in England (tho not to levels of the subsequent build-up) and the English had sufficient air-power to conduct 1000 bomber raids on cities in Germany's industrial heartland.
If the Luftwaffe could not prevent this, how do we imagine that they couild prevent raids on a similar level on any German beach-head on the English coast?
By the time, Luftwaffe already lost close to 10.000 planes on the eastern front, and 70% combat air units were stationed there. Germany industry suffered HUGE strain due to need to replace land army losses and manpower losses (mans drown from industry...). Imagine these GB bomber raids (already quite unsuccesfull) would encounter at least 5 times more fighters in they way to Germany...
Normandy 1944 showed how devastating tactical bombing by Bomber Command could be against German defences. This hypothetical has them bombing German troops in the open or in the most hastily prepared shelters.
1944 - not 1942. GB had much, much, much weaker Air forces in 1941/42. And VERY excaused Germany air defence in 1944 - is not 1941/42. Without war in Eastern front, Germany could allow order of magnitude large concentration of AA assets in France.
The problem is still larger than you think. When - not if - you fail...
~ You lose the moral or propaganda value of never having lost a major campaign. You still have to deal with Russia while having an encouraged and belligerent England on your back doorstep. (and in Africa)
As i said, there were no immedeatly need to deal with Russia. For all we know, USSR might wait its order to deal another 10 years
For USSR, Germany was counter-balance to GB & allies - these were percived just as dungerous (if not more) than Germany.
~ In preparation, you have diverted much more than just the infantry and armour divisions which you tried to send across the channel. You've had to divert resources into areas which give you little or no benefit when dealing with the Russians.
Of course. But why you such obsessed with Russians? I mean, USSR in 1940 is not the same as in 1960. It was order of magnitude weaker. Political situation looked much differently. Do not project later USSR image and power status to 1930x USSR - this is very common mistake.
Step back for a moment and consider how difficult the invasion of Normandy was for the Allies. It required an immense buildup of men and materials. It required months of preparatory bombing and sobotage. It required an intensive diversion campaign to convince the Wermacht that the landings would occur elsewhere. It required large quantities of new technology. It needed absolute air and naval superiority. The Allies had everything going for them and still it was hard.
Of course. But not becouse of some difficulties to cross channel. Nope. Mainly becouse german army was THAT strong EVEN in 1944, after all these defeats on Eastern front...
How are we supposed to think that the Wermacht conduct a succesful operation without these advantages and without the prior experience of making other contested landings?
Please consider,,,,,,,,, Peter
Becouse Wermacht was order of magnitude more powerfull than GB army.
