WI: BEF crushed at Dunkirk AND Britain refuses to surrender

As Dunkirk going worse for Britain is a frequent POD for Axis victories to prevent a continuing war with the United Kingdom, what if Britain suffered a devastating blow at Dunkirk with countless losses and refused to surrender afterwards? How well would Britain be able to perform in the Battle of Britain with fewer men available to her? Would Churchill be thrown out as bombs fell on London?

British were planning to fight on with or without the troops from Dunkirk. Given that the Luftwaffe sweeping enemy airforces from the skies was becoming a trend if the RAF manages its OTL performance which this PoD doesn't butterfly then Churchill won't be thrown out for keeping the country in the fight as it fights back against the German onslaught. Why would he be thrown out when IOTL he wasn't as bombs fell on London?

It's a frequent POD and it's an idiotic one.

Firstly, we can look at how much influence the British Army had on the Battle of Britain. Precisely zero. In order for Sealion to work, the RAF has to be neutralised, and the RN has to be neutralised. Since, OTL, the Luftwaffe couldn't manage the first step of that, how large or otherwise the disaster at Dunkirk was remains a complete irrelevance.

Given that bombs did indeed fall on London - rather a lot of them (and I can confirm given that I was born and grew up in the area hardest hit at a time when things that went bang were still falling) - and given that in OTL, there was nary a suggestion that Churchill be thrown out, I think we can safely say that it doesn't make a ha'porth of difference.

Britain isn't going to surrender. They could be weakened enough to accept an armistice.

How? Short of the RAF crashing into the sea and the RN wandering off to Canada for the duration, how exactly is Britain weakened sufficiently to enable Sealion to take place.

And, in the absence of a successful Sealion, why on earth would Britain consider an armistice?

And this presupposes that the Germans attack Dunkirk, which was:
(a) Not good tank terrain
(b) Using tanks and troops in need of rest, repair and recuperation.
(c) While France is still in the fight.

Point C is rather important, as diverting sufficient strength to roll up Dunkirk will give the French Army time to regather and reorganise, and leads to the probability that France never falls.

If the BEF were overrun, and to be clear the Halt Order was a sensible move and not some strategic mistake, then Chamberlain will carry the blame and it may make it easier for Churchill to remove those who supported Chamberlain's policies and left the BEF understrength and underequipped.

The impact would not be on the British Isles. It would be felt in the Middle East where the troops & equipment sent during the BoB OTL would almost certainly be retained for home defence.

Could also butterfly away the 2nd BEF.
 
I love the idea of the BEF 'being rolled up' as if it was not a modern army with modern arms capable of inflicting heavy losses

You get the impression with these posts that the Germans would defeat them with out firing a shot when actually it would require some very heavy fighting while there was already some very heavy fighting going on.

The issue is that while we up timers can look at History books and tease out a potential scenario where some of the leading Panzer might have made it to Dunkirk without encountering much resistance the leaders of the day did have that luxury and had to deal with the reality's on the ground

Post war some of the Panzer commanders went on and on about 'if only Hitler had not been so stupid with the Halt Order! We would have won tsk!' - but I smell BS.

There was not just the BEF but also much of the 1st French Army - half of which was fighting around Lille and the exhausted Panzers and motorised forces had been on the go for weeks and were strung out and needed to be rested and given time to reorg and repair their vehicles in order to defeat the rest of France which was no certain thing then.

Pervitin can only get you so far!

No far better for the BEF and half of 1st French Army to be holed up in Dunkirk where follow on forces could deal with them the Germans had no idea that the British could evacuate most of the force.

As has been mentioned the British army put about 3 million men into uniform in WW2 - and that does not include the RN, RAF and commonwealth forces - the loss of the BEF or at least the part of the BEF 'trapped' in Dunkirk was about 200,000 men and while this would have certainly caused a lot of issues as it included much of the regular pre-war army there was still significant forces in the UK.

In June 1940 after Dunkirk there was 27 Divisions in various states of TO&E and levels of training as well as numerous Brigade sized forces - the BEF at Dunkirk represented 9 of those.
 
To answer the OP. If (somehow) Germany takes ever single person at Dunkirk while losing next to no one, it still has very little effect.
GB is going to do what it did in the BoB and nothing at Dunkirk changes that.
You will not get a large moral boost without the “Miracle of Dunkirk” but that is not going to change much.
You probably see a bit more worry about “home defense” but that doesn’t change much.
You will see a decrease in troops deployed overseas in the short run. So you ,any not get the mess in Greece.
But in the long run not a lot will change.
This is a lot like a Peril Harbor POD. Not a lot changes in the long run.
 
The single biggest difference would be the number and type of munitions being purchased from the USA. I could also see more effort to rebuild the Army while using the RAF as a shield. The men lost are irreplaceable in the short term and does leave the army a little weaker than expected. The British literally would not surrender and the Empire means that the manpower lost can be replaced over time. India alone recruited some 2.5 million soldiers and every single one of them was a volunteer.

So if the British lose every single man of the army at Dunkirk you still have a very effective RAF, RN and also initially 2 divisions ready to fight along with numerous smaller units and also the men and material that got evacuated from other French Ports. All in all Dunkirk preserved the fighting man and morale. Those men became the nucleus of the remainder of the army.

After Dunkirk the British material deficiency was bad, it was improved rapidly and in some ways badly. For example the 2Lb AT gun and Tank gun was due to be replaced, the invasion scare was such that instead of retooling and making the 6lb AT gun and fitting it to tanks the 2lb gun was forced to continue. The paltry HE shell of the 2lb gun caused many casualties in the North Africa campaign.


The website linked is slow to load but a wealth of information. If Sea Lion had been remotely conceivable it had to be launched within 2 months and the RAF wiped out in that time. The RN also needed to be removed as a threat. Both of those are in ASB territory due to the reality's of amphibious landings against contested beaches.

For the Sea Mammal to be possible the Germans need to have spent the 30's building new barges for the Rhine capable of carrying and landing trucks and tanks. Also able to cross the channel and unload on a beach or Quay. What the Germans need is the LCM(https://en.wikipedia.org/wiki/Landi...s_LCM-3_at_Battleship_Cove,_Fall_River_MA.jpg) and they need at least a thousand of them. Why 1000 well it's a nice big number and also the minimum to carry 2 armoured divisions over but not to bring any of the support supplies etc. BTW D-Day used over 4,000 landing craft and followed them in with larger ships and a pair of Harbours. Literally D-Day was the finest co-ordination of military arm's up to that point.
 
Changes nothing
British empire can get over a million Canadians NZ Australian Indian African troops equipped in no time
 
Even with the BEF in the bag at Dunkirk there are still over 100,000 British troops fighting in France that were successfully withdrawn a month later and the troops in Norway that were in the process of being withdrawn to add to the armies building in the UK.

Why? Because the Germans overstretch themselves and get blown to pieces? The UK isn't weakened by a "No Halt Order"-pod, it's strengthened.

Militarily:

That was enough to persuade General von Rundstedt on 22 May to halt any further progress towards Boulogne and Calais until the threat had been contained. For twenty-four hours five German Panzer divisions sat waiting to resist a British counter-attack that existed only in the heads of their commanding officers. Much attention would be given later to Hitler’s fortyeight-hour ‘halt order’ to his tank crews on 24 May. But the halt two days earlier was far more significant. Had the German tanks continued to advance on 22 May at the same pace they had been doing for the last several days – and there is no obvious reason why they could not have done so – then Boulogne and Calais, still totally undefended, would have probably fallen without opposition within a few hours, and Dunkirk shortly afterwards. All the British troops further inland would have been trapped. Rommel’s panic attack unintentionally saved the BEF. 45

On the evening of 23 May, von Rundstedt ordered his Panzerdivisionen to halt their advance on Dunkirk to allow time for the German infantry to catch up. His order was confirmed by Hitler around noon the following day, and not rescinded until the evening of 26 May. Rumours circulated afterwards about the rationale for this famous ‘halt order’, the most sensational of which was that the Führer wished to spare the BEF from humiliating destruction as a goodwill gesture to the British government. There is no substance at all to this. Hitler probably saw the order simply as a way of imposing his will on his own commanding officers after days of confusion.55 After the war, surviving veterans of the 1940 campaign such as Panzer general Heinz Guderian blamed the halt order for allowing the BEF to escape and throwing away the chance of a total strategic victory. But it’s by no means obvious that the German tanks could have quickly seized Dunkirk even if they had been allowed to keep advancing on 23–4 May. Guderian’s men were exhausted, his vehicles were badly in need of maintenance and the Allied defensive line was much stronger than it had been a couple of days earlier. If there was a lost opportunity, it was probably the earlier halt order on 21 May caused by Rommel’s panicky overreaction to the Arras counter-offensive. 56

Gort’s decision was insubordinate. It was filled with risks. But it was absolutely the correct thing to do, as was demonstrated the following morning, when the War Cabinet changed its mind and approved it. Had Gort sent his last two spare divisions south-westwards on 25 May, it’s highly unlikely they could have accomplished anything. The BEF, meanwhile, would have been swiftly enveloped from the north and destroyed. If he had dithered for lack of instructions, the result would have been much the same. Gort was not a great general. His shortcomings had contributed to the disaster that had unfolded in France and Belgium, but his clear-minded courage on 25 May 1940 saved his army from capitulation and his country from losing the Second World War. Which is no bad epitaph to have.48

Politically:

The military background to what took place during these War Cabinet meetings is important. When discussions began on 26 May, Operation DYNAMO had only just been put into effect. About 25,000 British troops were extracted from the harbour and beaches of Dunkirk over the next forty-eight hours. Whether the Royal Navy could rescue many more soldiers than this was still not clear. If Dunkirk fell to the Germans quickly, as it seemed it might, only a small fraction of the total British force trapped in the Flanders pocket would get away. ‘Of course, whatever happens at Dunkirk, we shall fight on,’ Churchill said ‘quite casually’ at his meeting with the outer Cabinet on 28 May. 14 At the time, though, he had no way of knowing whether that was a pledge he could hold to. His statement to the Commons that evening was terse and gloomy. The House, he warned, ‘should prepare itself for hard and heavy tidings’.15 As Mason-MacFarlane’s apocalyptic briefing in the Berkeley Hotel illustrates, the Army itself had no confidence in success. What would have happened if DYNAMO had failed and most of the British troops in France and Flanders had been forced to surrender? Presumably, Churchill would have wanted to fight on regardless. There would have been voices in the Cabinet and the service ministries demanding the same. The RAF and RN might have insisted that the homeland was still safe from invasion by air and sea, for the time being anyway. But consider the context. The Germans would have just captured almost all the British Army. Hitler would be holding several hundred thousand soldiers, most of the country’s trained military personnel, as hostages. If, on 4 June 1940, Churchill had had to return to the House of Commons to announce not ‘a miracle of deliverance’ at Dunkirk but a dreadful mass capitulation, lacking any redeeming counter-narrative to soften the blow of defeat, it’s hard to imagine him being able then to go on to summon up much enthusiasm to fight on Britain’s beaches. At the very least, Halifax would surely have seized the opportunity to reopen the discussion of peace talks that he had been forced to abandon on 28 May. Churchillian hagiography today would have it that it was the prime minister’s iron will alone which kept Britain in the war in 1940. ‘Take away Churchill,’ according to Charles Krauthammer, ‘and Britain would have settled with Hitler – or worse. Nazism would have prevailed.’16 Boris Johnson echoed the same view in 2014, when he wrote: ‘without Churchill, Hitler would almost certainly have won […] only he could have done it.’17 But it was the success of DYNAMO, not Churchill imposing his resolve, however formidable, on his foreign secretary, that clinched the matter of whether Britain fought on in May 1940. Prime ministerial will was important, to be sure. But it was never enough by itself.
 
Militarily:
This has been disproven countless times. The troops that were ordered to halt were worn out and would have taken massive casualties while likely being unable to crush Dunkirk. And the Germans still have to deal with the French, if they take heavy losses fighting 350,000+ troops in terrain not made for tanks they may not be able to pull off Fall Rot.
Politically:
The British expected Dunkirk to be a disaster, and were planning to fight on. The whole "Halifax was one disaster away from overthrowing Churchill and getting Britain to sign an armistice" narrative has been proven wrong again and again.

As Dunkirk going worse for Britain is a frequent POD for Axis victories to prevent a continuing war with the United Kingdom, what if Britain suffered a devastating blow at Dunkirk with countless losses and refused to surrender afterwards? How well would Britain be able to perform in the Battle of Britain with fewer men available to her? Would Churchill be thrown out as bombs fell on London?

The BoB would go as the same as OTL . . . as it was one of the most stupidest military campaigns ever.

As for a more 'a devastating blow' at Dunkirk? . . . again it would go as in OTL.

Although it would be a sharp kick for the morale of the UK's public but since Britain had been fully mobilizing since war was declared in 1939 (basic training around 3 months????, stand corrected if wrong) there would be thousands of men entering into the defense of the UK every week.

The one thing that was missing was all BEF's firearms which were left on the beach.

If the UK can make and import (from Canada & the US) enough firearms to resupply the new recruits then it's game over.
