21 May 1940. 20:00hrs. Beaurains, France.
The command from General Martel to begin to withdraw after dark, was received by both wireless and dispatch rider and acknowledged. For the last few hours, the main activity in the region of the 4th Bn RTR and 6th DLI had been an artillery exchange between the 368th Battery RA and the German guns that were identified on Telegraph hill and towards Mercatel. As for the tanks and infantry, they had been busy digging themselves in and trying to cope with intermittent attacks from the air. Although a few tanks had tried to use their pompom guns to attempt to shoot down a Stuka, no other success had been achieved. A few officers in both the infantry and tank Battalions took note that in the absence of friendly aircraft, there needed to be something better than the AA platoon with its Bren guns.
At Agny, German motorcycle troops were probing the positions of B Company 6th DLI and C Coy 4th Bn RTR. The few surviving tanks from D Company 7th Bn RTR which had passed through them, had made their way back towards their own Battalion. The worry was if the British positions at Agny were by-passed, the withdrawal of the rest of 6th DLI and 4th Bn RTR from Beaurains would be interdicted. The commanders of the tank and infantry battalions, Lt-Col Fitzmaurice and Lt-Col Miller, tried to work out how best to leapfrog back to the original positions. Some RASC vehicles had managed to make it up to near the front lines, so the tanks had been able to refuel and rearm, making the journey back easier. One of the problems they worried about would be the probable loss of communication with the Royal Artillery battery. The Observation Post Officer, Lieutenant Boyd, had distinguished himself from his position in the belfry of the church.
The plan worked out was to pull back by Company, starting with C Company 6th DLI covering the road to Tilloy, along with B Company 4th RTR. They would take up a blocking position at Achicourt, where they would be joined by the tanks and infantry currently in Agny. The rest of 6th DLI, 206th Battery of 52nd Anti-tank Regiment RA, and 4th Bn RTR would pass through them and then hold at the railway line. Those at Achicourt would then move back to the original assembly point at Anzin-St Aubin, followed by the main force. Withdrawing under the cover of darkness is never an easy process, especially if the enemy were close by.
Just as the two Battalion commanders had finished their Orders Group to communicate and coordinate, there was a sudden increase in tempo of fire both incoming and outgoing. The officers and senior NCOs rushed back to their commands, to find that there had been some German probing at various points of the British defensive positions. With the sun having set and it seemed, the Luftwaffe’s operations over for the day, the British plan to withdraw was put into effect immediately. For the next two hours the leapfrogging of about a mile at a time went smoothly, until all the left column south of Arras arrived back at their assembly point, from where the weary infantry were able to climb aboard Brigade transport back behind Vimy Ridge. The 4th Bn RTR tanks rumbled their way back another six miles on their tracks towards Vimy, where they would be reunited with some of the tanks that had broken down on the journey south from Tournai.
The withdrawal from Duisans to Maroeuil for the 8th DLI and 7th Bn RTR was also straightforward, aided by the 9th DLI, the Brigade reserve sending some transport and carriers forward to bring back the battle-weary troops. The tanks moved back under their own steam, though B Company 7th Bn RTR stayed at Maroeuil with 9th DLI to support them and keep an eye on the road to St Pol.
General Franklyn had a very frank meeting with General Martel and Brigadier Pratt about the difference between what had been planned and what in fact had been achieved. The senior officer had to make a report to Lord Gort at BEF HQ and despite having given the Germans a bit of a punch, it wasn’t landed with the force expected in the planning. Martel and Pratt, despite having known and worked together at the Directorate of Mechanisation, were quite critical of one another. Martel thought that Pratt was overly careful, Pratt thought that Martel was wrong to send off the Infantry Tanks without infantry support. It would be a few hours before the individual reports from the four Battalion commanders could be properly digested. Until then Franklyn suggested everyone try to get some sleep before the Germans started their mischief in the morning.
NB: Italic text differs from OTL. This is much like what happened, though more often later at night, and not quite as easily as described here. I mentioned the arrival of 3e DLM tanks that saved the survivors of two companies 8th DLI at Warlus in the last update. I've deliberately finished the battle of Arras with the First Army Tank Brigade having fundamentally survived. The losses to 7th Panzer are slightly heavier than OTL, but by only about 40 tanks. The Germans however will have control of the battlefield and will therefore be able to recover more of their tanks, while the British won't. This is probably a better outcome than I had originally planned, and that comes down to a couple of small changes that could/should have been made OTL, to be honest I just found it impossible not to improve the British showing, which was almost unbelievably bad as it actually happened.
