22 May 1940. 23:00hrs. Koblenz, Germany.
It had been a long day and, unusually, operations in Army Group A had been at a slightly more sedate pace. The French counter-attack towards Cambrai had, like most French counter-attacks, been halted. If it had happened the day before, in concert with the British attack at Arras, it may well have had more serious consequences. The attack west of Arras in the evening convinced Von Rundstedt that his instinct to halt the attack on Boulogne and Calais were correct. The British and French in the north, were withdrawing from the Escaut line, after the battles there on 21 May. But the boil of Arras had to be lanced. If the French and British actually managed to make a combined counter-attack to cut off the Panzers from the Infantry, it could be a disaster in the making. With 5th Panzer Division, 20th Motorised Division and 12th Infantry Division now in place south of Arras, he would, the next morning, be able to get around Arras, and head north towards Lille. The 7th Panzer Division and SS Totenkopf Division had had a day to rest and refit. They would advance against the French to the left flank of 5th Panzer Division. As with the Fuhrer’s order in the morning, Von Rundstedt ordered the attack on Boulogne and Calais to be postponed again, an extra day would make little difference to the final outcome, even if Von Kleist complained again.
NB text in italic differs from OTL. The butterfly is at the end. A postponement now of two days instead of one of the attack on Boulogne and Calais.
