The British evacuation from Dunkirk is often described
as a miracle. Over 300,000 Allied soldiers pulled from the sea in the face of overwhelming odds
and the so-called 'Dunkirk spirit' that made it happen helping Britain through
its darkest hour. But what made the evacuations from Dunkirk
so successful? and are the myths surrounding the operation to be believed?
Well before we answer those questions and more a reminder to subscribe to
the Imperial War Museums YouTube channel for more videos just like this every two weeks.
The Dunkirk evacuation is looked upon as a miracle, a miracle of deliverance I think
Churchill himself called it in the House of Commons. But it's not so much a miracle as a
coming together of series of circumstances which played into the hands of Britain.
And to be fair to the Allies they hadn't had much luck so far.
Two weeks previously Germany began its invasion of the Low Countries with French and British forces
then moving into Belgium to meet them, however this attack was just a diversion.
Using cutting-edge blitzkrieg tactics German tanks smashed through the Allied weak point in
the Ardennes and dashed to the coast surrounding the allies. If you want to find out what made this
blitzkrieg attack so powerful we've got a video all about that linked in the description below.
In Belgium and part of Northern France, we have virtually the whole of the British expeditionary
force and a French army surrounded with their backs to the coast. So the British
army started thinking about evacuation before anybody else did because they thought they
might be able to save some of their army from what looked like a terrible disaster.
But time was against them, the german spearhead that had cut the Allies off
then began taking channel ports despite desperate Allied attempts to hold on to them. By May 26th
Dunkirk was the final port remaining. Worse still the port itself had been badly damaged,
leading to dire predictions of what would actually be possible during the evacuation.
Well, the initial thoughts of the British government and high command was that
they were going to try to save what they could. There was no expectation of getting the whole
British Expeditionary Force out they thought they might get act between 30 and 45,000 men.
Despite those predictions though the evacuation, codenamed Operation Dynamo,
eventually managed to save over 338,000 Allied soldiers. So how did they do it? Well according
to Paul there are three things that made these evacuations so successful. First was the weather.
Yeah, the weather could hardly have been more favourable. There were very unusually for that
time of year very light winds for most days there was not a lot of surf on the beach.
That allowed men to load into smaller boats right on the beaches before boarding for larger ships,
an impossible task on windier days, and when there was wind,
that played into the Allies hands as well.
The wind was from the east which blew smoke from the burning port of Dunkirk across the
beach offering a bit of cover from air attack and also there's some low cloud
for most of the period of the evacuation. Low cloud over the beach also protected
the troops from air attack so they won in every sense weather-wise.
Next up was a bit of ingenuity from the naval officer in charge of the evacuation, Captain
William Tennant, which goes against one of those classic Dunkirk narratives. One of the things we
remember or think we remember about Dunkirk is the little boats who took men off the beaches.
Certainly they were there, over 300 of them, but that was a minority of the men who escaped.
Most of the evacuation took place across one of the harbour breakwaters at Dunkirk.
This was a very narrow thing with a walkway on top of it. Most of the men,
I think around 200,000 of the 338,000 men, came off through that route as opposed to the beaches.
The harbour mole was so effective because it allowed troops to step right from the harbour
onto destroyers or other large ships rather than going through the time-consuming process
of taking smaller boats from the beach. The mole was never designed to be used this way,
but it was a major factor in making the Dunkirk evacuations such a success.
Finally, let's look at the infamous german halt order
which gave the Allies valuable time to create a defensive perimeter around the port of Dunkirk.
People in the higher German command basically could not believe their luck. They always were
assuming that the French would manage to launch a counter-attack and cut off those tanks that were
advancing with such speed. They kept trying to get tanks to slow down so the infantry could
catch up and so this halt order on the 24th of May is sort of another iteration of that caution.
Another key issue were further Allied garrisons at other important towns.
British defenders at Calais held on against all the odds until May 26th
while French forces in Lille managed to occupy 10 German divisions alone.
The Germans realised that,
even though they won this battle effectively, they had not defeated France. France still had
a huge army and they were going to need all their tanks in order to achieve this after they dealt
with whatever happened at Dunkirk. They also thought that the German air force could destroy
the troops in the bridgehead or any ships trying to save them, this was why that order was issued.
Bring all of this together and you can see why so many more troops were saved than expected.
The weather providing valuable cover from air attack, the harbour mole allowing extra men
to embark, and the German halt order giving the Allies valuable time to set up defences.
But what was it actually like to be in the town of Dunkirk?
The soldiers there had a variety of experience and the British Army
behaved in a variety of different ways. There was some heroism,
on the other hand, there were instances of disorder and instances of panic.
Scenes on the beaches varied from boredom as soldiers waited for pickup, to bedlam as
the Luftwaffe swirled overhead. According to one soldier writing in his diary on May 30th,
the situation was desperate "every man for himself getting loaded".
We have in our collection a small French railway map which was
pinched from the wall of a cafe by a soldier Bill Osborne. He expected
that he might get separated from his unit and have to find his own way to the coast
things were that chaotic. He also wrote a letter on a scrap of paper to his wife anticipating that
he would be killed and telling her to make a new life with somebody else if she could.
And for the soldiers who did escape the stress was
not over. They were expecting a frosty reception on their return to Britain.
They thought that they would be vilified by the public. They thought that they'd arrived
home with their tail between their legs and yet they found themselves treated largely as heroes
uh because people were so relieved at having saved so many men and this,
for obvious reasons of national morale, was the line pushed by the press and the BBC. It
was extraordinary that they'd saved as many men as they had, well what it didn't point out was
that we'd had to leave all our equipment behind and Britain was effectively open to invasion at
that point had the germans had either the plans or the will or the ability to do it.
And that's the reason that so many of these myths surrounding Dunkirk exist. British
morale was at a low point and so the British press emphasized stories of heroism like those so-called
little ships. Most of those craft were piloted by Royal Navy crews rather than civilians
and yet these stories of plucky Brits winning against the odds
are the stories which have stuck around, part of what's become known as the 'Dunkirk spirit'.
The myth certainly was necessary at the time you know keep people's morale up.
Although Churchill in the House of Commons was was fairly straight with the House of Commons
and said you know this is a deliverance but "wars are not won by evacuations".
Victory for Britain was a long way off, but the evacuation at Dunkirk was one of the few rays
of light in the Allied cause. It was a great success coming at the end of a dismal failure,
a success which kept the British army intact and British morale afloat,
for now. The following month France surrendered to Germany. The battle of Britain was about to begin
