Their Finest Hour (11 page)

This did less than justice to our troops. But I print it as I wrote it at the time.

Prime Minister to General Ismay.

24.V.40.

Vice Chief of the Naval Staff informs me that [an] order was sent at 2
A.M.
to Calais saying that evacuation was decided in principle, but this is surely madness. The only effect of evacuating Calais would be to transfer the forces now blocking it to Dunkirk. Calais must be held for many reasons, but specially to hold the enemy on its front. The Admiralty say they are preparing twenty-four naval twelve-pounders, which with S.A.P.

will pierce any tank. Some of these will be ready this evening.

Prime Minister to C.I.G.S.

I must know at earliest why Gort gave up Arras, and what actually he is doing with the rest of his army. Is he still persevering in Weygand’s plan, or has he become largely stationary? If the latter, what do you consider the probable course of events in the next few days, and what course do you recommend? Clearly, he must not allow himself to be encircled without fighting a battle. Should he [not] do this by fighting his way to the coast and destroying the armoured troops which stand between him and the sea with overwhelming force of artillery, while covering himself and the Belgian front, which would also curl back, by strong rearguards? Tomorrow at latest this decision must be taken.

It should surely be possible for Dill to fly home from any aerodrome momentarily clear, and R.A.F. should send a whole squadron to escort him.

Prime Minister to Secretary of State for War, and C.I.G.S.

25.V.40.

Pray find out who was the officer responsible for sending the order to evacuate Calais yesterday, and by whom this very lukewarm telegram I saw this morning was drafted, in which mention is made of “for the sake of Allied solidarity.” This is not the way to encourage men to fight to the end. Are you sure there is no streak of defeatist opinion in the General Staff?

Prime Minister to C.I.G.S.

Something like this should be said to the Brigadier defending Calais: Defence of Calais to the utmost is of the highest importance to our country and our Army now. First, it occupies a large part of the enemy’s armoured forces, and keeps them from attacking our line of communication. Secondly, it preserves a sally-port from which portions of the British Army may make their way home. Lord Gort has already sent troops to your aid, and the Navy will do all possible to keep you supplied. The eyes of the Empire are upon the defence of Calais, and His Majesty’s Government are confident that you and your gallant regiment will perform an exploit worthy of the British name.

This message was sent to Brigadier Nicholson at about 2
P.M
. on May 25.

The final decision not to relieve the garrison was taken on the evening of May 26. Till then the destroyers were held ready. Eden and Ironside were with me at the Admiralty. We three came out from dinner and at 9
P.M
. did the deed. It involved Eden’s own regiment, in which he had long served and fought in the previous struggle. One has to eat and drink in war, but I could not help feeling physically sick as we afterwards sat silent at the table.

Here was the message to the Brigadier:

Every hour you continue to exist is of the greatest help to the B.E.F. Government has therefore decided you must continue to fight. Have greatest possible admiration for your splendid stand. Evacuation will not (repeat
not)
take place, and craft required for above purpose are to return to Dover.

to cover Commander minesweeping and his retirement.

Calais was the crux. Many other causes might have prevented the deliverance of Dunkirk, but it is certain that the three days gained by the defence of Calais enabled the Gravelines waterline to be held, and that without this, even in spite of Hitler’s vacillations and Rundstedt’s orders, all would have been cut off and lost.

* * * * *

Upon all this there now descended a simplifying catastrophe. The Germans, who had hitherto not pressed the Belgian front severely, on the 24th of May broke the Belgian line on either side of Courtrai, which is but thirty miles from Ostend and Dunkirk. The King of the Belgians soon considered the situation hopeless, and prepared himself for capitulation.

By May 23 the First and Second Corps of the British Expeditionary Force, withdrawn by stages from Belgium, were back again on the frontier defences north and east of Lille, which they had built for themselves during the winter. The German scythe-cut round our southern flank had reached the sea, and we had to shield ourselves from this. As the facts forced themselves upon Gort and his headquarters, troops had successfully been sent to positions along the canal line La Bassée-Béthune-Aire-St. Omer-Watten. These, with elements of the French Sixteenth Corps, touched the sea at the Gravelines waterline. The British Third Corps was responsible in the main for this curled-in flank facing south. There was no continuous line, but only a series of defended “stops” at the main crossings, some of which, like St. Omer and Watten, had already fallen to the enemy. The indispensable roads northward from Cassel were threatened. Gort’s reserve consisted only of the two British divisions, the 5th and 50th, which had, as we have seen, just been so narrowly extricated from their southerly counterattack made at Arras in forlorn fulfilment of the Weygand plan. At this date the total frontage of the B.E.F. was about ninety miles, everywhere in close contact with the enemy.

To the south of the B.E.F. lay the First French Army, having two divisions in the frontier defences and the remainder, comprising eleven divisions in no good shape, cramped in the area north and east of Douai. This army was under attack from the southeast claw of the German encirclement. On our left the Belgian Army was being driven back from the Lys Canal at many places, and with their retirement northward a gap was developing north of Menin.

In the evening of the 25th, Lord Gort took a vital decision. His orders still were to pursue the Weygand plan of a southerly attack towards Cambrai, in which the 5th and 50th Divisions, in conjunction with the French, were to be employed. The promised French attack northward from the Somme showed no sign of reality. The last defenders of Boulogne had been evacuated. Calais still held out. Gort now abandoned the Weygand plan. There was in his view no longer hope of a march to the south and to the Somme. Moreover, at the same time the crumbling of the Belgian defence and the gap opening to the north created a new peril, dominating in itself. A captured order of the German Sixth Army showed that one corps was to march northwestward towards Ypres and another corps westward towards Wytschaete. How could the Belgians withstand this double thrust?

Confident in his military virtue, and convinced of the complete breakdown of all control, either by the British and French Governments or by the French Supreme Command, Gort resolved to abandon the attack to the southward, to plug the gap which a Belgian capitulation was about to open in the north, and to march to the sea. At this moment here was the only hope of saving anything from destruction or surrender. At 6
P.M.
he ordered the 5th and 50th Divisions to join the Second British Corps to fill the impending Belgian gap. He informed General Blanchard, who had succeeded Billotte in command of the First Army Group, of his action; and this officer, acknowledging the force of events, gave orders at 11.30
P.M.
for a withdrawal on the 26th to a line behind the Lys Canal west of Lille, with a view to forming a bridgehead around Dunkirk.

Early on May 26, Gort and Blanchard drew up their plan for withdrawal to the coast. As the First French Army had farther to go, the first movements of the B.E.F. on the night of May 26/27 were to be preparatory, and rearguards of the British First and Second Corps remained on the frontier defences till the night of May 27/28. In all this Lord Gort had acted upon his own responsibility. But by now we also at home, with a somewhat different angle of information, had already reached the same conclusions. On the 26th a telegram from the War Office approved his conduct, and authorised him “to operate towards the coast forthwith in conjunction with the French and Belgian armies.” The emergency gathering on a vast scale of naval vessels of all kinds and sizes was already in full swing.

The reader must now look at the diagram which shows the general areas held on the night of May 25/26 by the British divisions.

On the western flank of the corridor to the sea the position remained largely unchanged during the 26th. The localities held by the 48th and 44th Divisions came under relatively little pressure. The 2d Division, however, had heavy fighting on the Aire and La Bassée Canals, and they held their ground. Farther to the east a strong German attack developed around Carvin, jointly defended by British and French troops. The situation was restored by the counterattack of two battalions of the 50th Division, which were in bivouac close by. On the left of the British line the 5th Division, with the 143d Brigade of the 48th Division under command, had travelled through the night, and at dawn took over the defence of the Ypres-Comines Canal to close the gap which had opened between the British and Belgian armies. They were only just in time. Soon after they arrived the enemy attacked, and the fighting was heavy all day. Three battalions of the 1st Division in reserve were drawn in. The 50th Division, after bivouacking south of Lille, moved northward to prolong the flank of the 5th Division around Ypres. The Belgian Army, heavily attacked throughout the day and with their right flank driven in, reported that they had no forces with which to regain touch with the British line, and also that they were unable to fall back to the line of the Yser Canal in conformity with the British movement.

Meanwhile, the organisation of the bridgeheads around Dunkirk was proceeding. The French were to hold from Gravelines to Bergues, and the British thence along the canal by Furnes to Nieuport and the sea. The various groups and parties of all arms which were arriving from both directions were woven into this line. Confirming the orders of the 26th, Lord Gort received from the War Office a telegram, despatched at 1
P.M.
on the 27th, telling him that his task henceforward was “to evacuate the maximum force possible.” I had informed M. Reynaud the day before that the policy was to evacuate the British Expeditionary Force, and had requested him to issue corresponding orders. Such was the breakdown in communications that at 2
P.M.
on the 27th the commander of the First French Army issued an order to his corps,
“La bataille sera livrée sans esprit de recul sur la position de la Lys.”

Four British divisions and the whole of the First French Army were now in dire peril of being cut off around Lille. The two arms of the German encircling movement strove to close the pincers upon them. Although we had not in those days the admirable map rooms of more coherent periods, and although no control of the battle from London was possible, I had for three days past been harrowed by the position of the mass of Allied troops around Lille, including our four fine divisions. This, however, was one of those rare but decisive moments when mechanical transport exercises its rights. When Gort gave the order, all these four divisions came back with surprising rapidity almost in a night. Meanwhile, by fierce battles on either side of the corridor, the rest of the British army kept the path open to the sea. The pincer-claws, which were delayed by the 2d Division, and checked for three days by the 5th Division, eventually met on the night of May 29 in a manner similar to the great Russian operation round Stalingrad in 1942. The trap had taken two and a half days to close, and in that time four British divisions and a great part of the First French Army, except the Fifth Corps, which was lost, withdrew in good order through the gap, in spite of the French having only horse transport, and in spite of the main road to Dunkirk being already cut and the secondary roads filled with retiring troops, long trains of transport, and many thousands of refugees.

The question about our ability to go on alone, which I had asked Mr. Chamberlain to examine with other Ministers ten days before, was now put formally by me to our military advisers. I drafted the reference purposely in terms which, while giving a lead, left freedom to the Chiefs of Staff to express their view, whatever it might be. I knew beforehand that they were absolutely determined; but it is wise to have written records of such decisions. I wished, moreover, to be able to assure Parliament that our resolve was backed by professional opinion. Here it is, with the answer:

We have reviewed our report on “British Strategy in a Certain Eventuality” in the light of the following terms of reference remitted to us by the Prime Minister.

“In the event of France being unable to continue in the war and becoming neutral, with the Germans holding their present position and the Belgian army being forced to capitulate after assisting the British Expeditionary Force to reach the coast; in the event of terms being offered to Britain which would place her entirely at the mercy of Germany through disarmament, cession of naval bases in the Orkneys, etc.; what are the prospects of our continuing the war alone against Germany and probably Italy? Can the Navy and the Air Force hold out reasonable hopes of preventing serious invasion, and could the forces gathered in this island cope with raids from the air involving detachments not greater than ten thousand men; it being observed that a prolongation of British resistance might be very dangerous for Germany engaged in holding down the greater part of Europe?”

2. Our conclusions are contained in the following paragraphs.

3. While our Air Force is in being, our Navy and Air Force together should be able to prevent Germany carrying out a serious seaborne invasion of this country.

4. Supposing Germany gained complete air superiority, we consider that the Navy could hold up an invasion for a time, but not for an indefinite period.

5. If, with our Navy unable to prevent it, and our Air Force gone, Germany attempted an invasion, our coast and beach defences could not prevent German tanks and infantry getting a firm footing on our shores. In the circumstances envisaged above our land forces would be insufficient to deal with a serious invasion.

6. The crux of the matter is air superiority. Once Germany had attained this, she might attempt to subjugate this country by air attack alone.

7. Germany could not gain complete air superiority unless she could knock out our Air Force, and the aircraft industries, some vital portions of which are concentrated at Coventry and Birmingham.

8. Air attacks on the aircraft factories would be made by day or by night. We consider that we should be able to inflict such casualties on the enemy by day as to prevent serious damage. Whatever we do, however, by way of defensive measures – and we are pressing on with these with all despatch – we cannot be sure of protecting the large industrial centres, upon which our aircraft industries depend, from serious material damage by night attack. The enemy would not have to employ precision bombing to achieve this effect.

9. Whether the attacks succeed in eliminating the aircraft industry depends not only on the material damage by bombs, but on the moral effect on the workpeople and their determination to carry on in the face of wholesale havoc and destruction.

10. If therefore the enemy presses home night attacks on our aircraft industry, he is likely to achieve such material and moral damage within the industrial area concerned as to bring all work to a standstill.

11. It must be remembered that numerically the Germans have a superiority of four to one. Moreover, the German aircraft factories are well dispersed and relatively inaccessible.

12. On the other hand, so long as we have a counter-offensive bomber force, we can carry out similar attacks on German industrial centres and by moral and material effect bring a proportion of them to a standstill.

13. To sum up, our conclusion is that
prima facie
Germany has most of the cards; but the real test is whether the morale of our fighting personnel and civil population will counterbalance the numerical and material advantages which Germany enjoys. We believe it will.
