To make sure there was no mistake about what was settled, I myself dictated a résumé of the decisions and showed it to Weygand, who agreed. I reported accordingly to the Cabinet and sent the following telegram to Lord Gort:

22.V.40.

I flew to Paris this morning with Dill and others. The conclusions which were reached between Reynaud, Weygand, and ourselves are summarised below. They accord exactly with general directions you have received from the War Office. You have our best wishes in the vital battle now opening towards Bapaume and Cambrai.

It was agreed:

1. That the Belgian Army should withdraw to the line of the Yser and stand there, the sluices being opened.

2. That the British Army and the French First Army should attack southwest towards Bapaume and Cambrai at the earliest moment certainly tomorrow – with about eight divisions – and with the Belgian Cavalry Corps on the right of the British.

3. That as this battle is vital to both armies and the British communications depend upon freeing Amiens, the British Air Force should give the utmost possible help, both by day and by night, while it is going on.

4. That the new French Army Group which is advancing upon Amiens and forming a line along the Somme should strike northward and join hands with the British divisions who are attacking southward in the general direction of Bapaume.

It will be seen that Weygand’s new plan did not differ except in emphasis from the cancelled Instruction No. 12 of General Gamelin. Nor was it out of harmony with the vehement opinion which the War Cabinet had expressed on the 19th. The Northern Armies were to shoulder their way southward by offensive action, destroying, if possible, the armoured incursion. They were to be met by a helpful thrust through Amiens by the new French Army Group under General Frère. This would be most important if it came true. In private I complained to M. Reynaud that Gort had been left entirely without orders for four consecutive days. Even since Weygand had assumed command three days had been lost in taking decisions. The change in the Supreme Command was right, The resultant delay was evil.

I slept the night at the Embassy. The air raids were trivial; the guns were noisy, but one never heard a bomb. Very different indeed were the experiences of Paris from the ordeal which London was soon to endure. I had a keen desire to go to see my friend General Georges at his headquarters at Compiègne. Our liaison officer with him, Brigadier Swayne, was with me for some time and gave me the picture of the French armies so far as he knew it, which was only part of the way. I was persuaded that it would be better not to intrude at this time, when this vast and complicated operation was being attempted in the teeth of every form of administrative difficulty and frequent breakdowns in communication.

In the absence of any supreme war direction, events and the enemy had taken control. On the 17th, Gort had begun to direct troops to the line Ruyaulcourt-Arleux and to garrison Arras, and was constantly strengthening his southern flank. The French Seventh Army, less the Sixteenth Corps, which had suffered heavily in the Walcheren fighting, had moved south to join the First French Army. It had traversed the British rear without serious disturbance. On the 20th, Gort had informed both Generals Billotte and Blanchard that he proposed to attack southward from Arras on May 21 with two divisions and an armoured brigade, and Billotte had agreed to co-operate with two French divisions from the First French Army. This army of thirteen divisions was gathered in an oblong some nineteen miles by ten – Maulde-Valenciennes-Denain-Douai. The enemy had crossed the Scheldt on the 20th around Oudenarde, and the three British corps, which still faced east, withdrew on the 23d to the defences we had erected in the winter along the Belgian frontier, from which they had advanced so eagerly twelve days before. On this day the B.E.F.
